Solar Thermal

A Few FactsA solar thermal solution will provide a typical UK household with 50

to 60% of their Domestic Hot Water in a year. In the summertime

this will be as high as 100% meaning that the boiler will never have

to fire up saving both energy and money. In the winter a lower level

of energy is produced by the sun, so a boiler is also needed to

provide energy to heat the domestic hot water.

It’s a common misconception that solar thermal systems only work

when the sun is shining. Solar thermal systems work with diffused

radiation, so even on a cloudy day you will still get a good level of

energy from the sun to heat your hot water.

It doesn’t matter where you live in the UK, Solar Thermal will

still provide you with domestic hot water, whether you live in

John O’Groats or Lands End.

A Typical Solar System

Glow-worm offer a complete Clearly Solar Design Service to suit

your individual site development requirements.

Specifications are incredibly important for solar and need to be

taken into account at roof design stage as well as the heating

What Size System Do I Need?A Clearly Solar system should always be sized by a qualified solar

installer, but to give you an idea of what you need please see the

chart below.

Minimum number of persons inhousehold

Maximum number of persons inhousehold

Household average daily hotwater usage Up to 100l 80l to 120l 100l to 140l 120l to 180l

Number of collectors(each collector is 2m2)

Cylinder Size*

Basic Guide to System Sizing

The panels collect energy from the sun which heats the fluid in the

solar panel.

When the fluid in the panels is hot enough, the pump station

circulates the hot fluid around the system

The hot fluid is pumped around the coil at the bottom of the twin

coil cylinder and heats the potable (or mains) water held within the

cylinder for domestic use.

The solar controller is the brains of the operation, managing the

solar system during daylight hours, enabling you to time your hot

water, just like a heating programmer, and measure the amount of

energy you have gained from the sun.

If the temperature sensor in the cylinder detects that the solar panel

hasn’t collected enough energy to heat the hot water to the

required temperature, that’s when the boiler will fire up, heat the

top coil of the cylinder and top up the temperature of the hot water

so that it comes out of your taps at the temperature needed.

200l 200-250l 250-300l 300lNote: This system sizing rule of thumb will deliver 60% of annual DHW assuming near optimum collector orientation (e.g. 30º inclination and south facing based on a 2 or 3 panelkit). For precise sizing contact a qualified installer or Glow-worm’s technical helpline

* Cylinders should be correctly sized

Glow-worm Clearly Solar Systems

Designed for use on UK homes, ClearlySolar has everything you need to look forin a flat plate solar thermal solution.

Robust, hard wearing and high performance flat plates delivering

excellent levels of efficiency, lots of flexibility in installation and a

sleek and subtle design of all components on the roof and inside

the house, plus advanced controls that ensure you squeeze every

last drop of energy from the sun.

Clearly Solar is a pressurised system, meaning that it is completely

full of heat transfer fluid and sealed from the atmosphere

(a similar concept to a sealed heating system). Fully compatible

4

with all new and existing open vent and sealed system boilers

(including the complete Glow-worm range) or immersion heaters

in non-gas areas. Glow-worm Clearly Solar will deliver an average

of 50 to 60% of your annual domestic hot water needs.

On-roof installation

5

Made of brushed aluminium with a neat design that subtly fits

with the roof, Clearly Solar flat plates can be installed both in-roof

and on-roof, horizontally or vertically, or fixed to A-frames and

mounted on a flat roof or in a garden.

We also provide a range of Clearly Solar accessories to give you

flexibility of installation. This includes a variety of fixing brackets to

suit all types of roof tiles including concrete, slate and clay peg

and tools to help you out on the job including, harnesses, carrying

handles and filling pump.

Glow-worm Clearly Solar is the straight forward solar thermal

solution perfect for the needs of UK homes

In-roof installation

Clearly Solar Systems | Key Components

6

Flurosorb Flat Plates

The Flurosorb flat plate (part of the Clearly Solar system) gives you,

high efficiencies from a large absorber area of 2.02m2, robust

construction from toughened glass and ultrasonic welding, whilst

the slim line frame gives it a total footprint of just 2.24m2 and at

43kg it is one of the lightest flat plates on the market.

Flurosorb flat plates can be installed both in-roof and

on-roof, horizontally or vertically, or fixed to A-frames and

mounted on a flat roof or in a garden. The neat design subtly fits

in with the roof and low protrusion making it well within the

threshold normally required for planning permission.

Construction:

• Brushed aluminium frame

• Grid absorber made of copper

• Solar glass thickness 4mm (tough and resistant to vandalism)

• Absorber ultrasonically welded and not soldered, suitable for

high temperature

• High selective absorber coating

Dimensions:

• Dimensions 1.16x1.93m

• Gross collector area 2.24m2

• Absorber surface areas 2.02m2

• Low flat plate weight only 43kg

• Total depth 110mm achieving low protrusion

Performance:

• Leading performance flat plate collector

• Collector efficiency 81.8%

• Light transmission 91%

• Solar radiation absorption 95%

• Solar radiation emission 5%

• Shutdown temperature 196ºC

• 60mm insulation for improved efficiency

• 10 year warranty

Fixing:

• Horizontal and vertical orientation possible

• Mounting accessories for pitched roofs (On-roof and in-roof)

• A-frame for flat roofs

Fluropro Controller

The Fluropro controller (part of the Clearly Solar system) is the real

brains of the operation, simple to use with a boiler domestic hot

water programmer and solar gain display to show how much

energy has been collected from the sun since the system began

operating. Intelligent functionality in the controller holds off the

boiler whenever there is solar gain to be had making fuel usage as

low as possible.

• Differential temperature control

• East / West system control

(additional collector sensor and

pump station connection)

• Solar gain display

• Temperature sensors

• Three channels (solar, boiler, auxiliary heating)

• Programmable boiler & auxiliary channels

• Easy wiring connections

• Solar gain modulation

• Boiler heating delay function (similar to optimum start)

7

Flurocyl Twin Coil Cylinder

Unvented, stainless steel and narrow enough to fit through any

standard airing cupboard door, the Flurocyl twin coil cylinder (part

of the Clearly Solar system) is a cylinder for all seasons.

To ensure that every last bit of the suns energy is used, the solar

gain modulation (working with the controller and pump station)

steadily pulses the solar fluid into the bottom coil of the cylinder,

evenly heating the domestic hot water and ensuring that the boiler

does not fire up until it really needs to.

The special construction of the coils inside the Flurocyl cylinder,

ensures that the top coil will reliably heat the top 2/3 of the cylinder

delivering high volumes of hot water during winter months when

there is less solar energy.

The Flurocyl cylinder is supplied with a thermostatic mixing valve

to mix cold water into the solar heated water as required and 3

thermal cut outs for the boiler, immersion and solar, all fully

integrated and approved.

• Twin coil Flurocyl cylinder fully compatible with all open vent

and sealed systems, including the full range of Glow-worm

boilers

• Available in 200, 250 and 300 litres

• High grade stainless steel cylinder with laser welded seams

• Insulation meets CHeSS best practice (loss as low as 1.9kWh)

• 25 year warrantee in cylinder shell

• 554mm width for flexible siting

• 3kW immersion heater as standard

• 3 thermal cut outs (boiler, immersion and solar)

• Supplied with a carrying handle for easy of transportation

Solar Pump Station

The Solar Pump Station (part of the Clearly Solar system), pumps

the solar fluid from the flat plate to the cylinder and back again. Its

compact design fits easily on the wall in the house or loft. The three

speed pump enables you to match the flow rate of the system to a

wide range of properties.

Because heat naturally rises the pump station is fitted with 2 check

valves which stops circulation of the solar fluid when the pump is not

running, forcing the heat to stay in the cylinder rather than

transferring back into the flat plate, increasing system efficiency.

• 6m head pump

• Integrated flow meter

• Two isolation valves

• Two non-return valves

• Two temperature gauges

• Pressure gauge

• Pressure relief valve

• Expansion vessel connection

• Integrated slow adjuster and meter

New Generation in Glow-wormHeating and Hot Water Systems

For years the Glow-worm xi range of boilers has served the British

public well, becoming one of the most popular choices in the

UK market.

As technology and customer needs develop over time even the

most popular models need to move with the times. This is why

Glow-worm have developed a new generation of advanced

boilers to replace the xi range.

Introducing the Ultracom

The Ultracom is based on 4th generation tried and tested

technology. We have kept all the great bits of the xi, like the

stainless steel heat exchanger and extensive flueing options

and enhanced it with technically advanced inbuilt digital

user controls, improved aesthetics and drop down wiring

connections for easier installation.

This makes the Ultracom not only exceptionally reliable and easy

to install, but also easier to program, better to look at and

provides increased system control to the homeowner.

Providing the complete system package

The new Ultracom range is SEDBUK A rated and available as

a Combi, Open Vent or Sealed System boiler in a

wide variety of outputs to suit all domestic needs.

We also provide Cylinders (page 14), Plume Management Kits

(page 15), Condensate Pumps (page 15) and a brand new range

of Glow-worm controls (pages 6, 7, 12 and 13) which are simple

to fit and designed to talk to the Glow-worm boiler, giving you

everything you need to complete the job.

Condensate Pump

Unlike old standard efficiency boilers, High Efficiency Condensing

boilers produce water in the form of condensate as a by-product

of operating more efficiently. This is a great benefit for the

environment, but can make installation more difficult in places

with restricted access to a waste drain pipe, like the basement.

To remove this problem and enhance the siting flexibility of

the Ultracom cxi, hxi and sxi, Glow-worm have produced a

condensate pump to collect the condensate from the boiler and

pump it back into the waste system.

The Glow-worm Condensate Pump is the smallest available in the

UK, being smaller than a shoe box, it operates at maximum

efficiency, with the reservoir pump discharging the condensate in

one go when the fill level is reached rather than as a continuous

operation. In the unlikely event of the condensate pump

becoming too full, the overflow safety switch will shut the

Ultracom down and the pump’s LED display will go red indicating

a fault.

• Smallest condensate pump in the UK

• Compatible with all Glow-worm Ultracom models

• Vertical pump height up to 4m

• 6m discharge hose for connecting the pump to thewaste water system

• Over flow safety switch

Plume Management Kit

Plume is the vapour trail that is

seen coming from the front,

back or sides of a house when

the flue gas temperature drops

below the dew point. It can

happen with all boilers, but is

more significant on high

efficiency condensing boilers.

Plume is not harmful but can

be viewed as unsightly and can

potentially be a nuisance if it drifts across neighbours properties

or public areas. This is why Glow-worm provides the Plume

Management Kit.

The simple piping kit fits neatly onto the horizontal flue of

any Glow-worm high efficiency boiler installed in the UK. The kit

enables the plume to be exhausted further away from the flue

duct, reducing the visual impact of the vapour trail.

The Plume Management Kit can also be used to overcome many

more site issues. The kit can be extended to a maximum of 6m

in length and can be directed around ledges and other obstacles

to easily achieve the minimum clearance required on installation

without having to do the costly and difficult job of relocating

a boiler.

• Siting on wall face or above the eaves of a building

• Can be retro-fitted to any existing Glow-worm

High Efficiency installation

• Additional elbows, bends and 1-meter extensions available

• Simple push-fit connection

• Available in black or white to match rain water fittings

New Generation in Glow-wormHeating and Hot Water Systems

For years the Glow-worm xi range of boilers has served the British

public well, becoming one of the most popular choices in the

UK market.

As technology and customer needs develop over time even the

most popular models need to move with the times. This is why

Glow-worm have developed a new generation of advanced

boilers to replace the xi range.

Introducing the Ultracom

The Ultracom is based on 4th generation tried and tested

technology. We have kept all the great bits of the xi, like the

stainless steel heat exchanger and extensive flueing options

and enhanced it with technically advanced inbuilt digital

user controls, improved aesthetics and drop down wiring

connections for easier installation.

This makes the Ultracom not only exceptionally reliable and easy

to install, but also easier to program, better to look at and

provides increased system control to the homeowner.

Providing the complete system package

The new Ultracom range is SEDBUK A rated and available as

a Combi, Open Vent or Sealed System boiler in a

wide variety of outputs to suit all domestic needs.

We also provide Cylinders (page 14), Plume Management Kits

(page 15), Condensate Pumps (page 15) and a brand new range

of Glow-worm controls (pages 6, 7, 12 and 13) which are simple

to fit and designed to talk to the Glow-worm boiler, giving you

everything you need to complete the job.

Amazinglyflexible

Available with a direct rearflue option

So small, it can fit inside a kitchenwall cupboard

FlexicomAmazingly flexible, surprisingly compact.So much more than High Efficiency.

To replace an old boiler or install a new one with the minimum of

fuss, you need a boiler that will fit just about anywhere. That’s

why Glow-worm created the Flexicom.

The Flexicom has a direct rear flue and is so compact it fits inside

a standard kitchen cupboard. The Flexicom gives you loads of

siting flexibility, particularly useful when replacing a standard

efficiency boiler with an existing direct rear flue or if space is a

premium in the property you are working in.

The pull-out electrical connection block means that you don’t

have to remove the front case during installation and the

pre-fixing jig, upward piping frame and technical back-up

provided by Glow-worm, should you ever need it, are all designed

to make installation as easy as we can for you.

Available as a Combi, Open Vent or Sealed System boiler with a

wide range of outputs, the Flexicom has the best possible rating

for energy efficiency being SEDBUK A rated with a NOx class 5

rating and recommended by the Energy Saving Trust.

installation and compact size which means you are able to fit it inside

a standard kitchen cupboard*.

Available in 24, 30 & 35kW models, the Flexicom cx provides

excellent domestic hot water performance with a 5 second hot water

delivery**. It is also recommended by the Energy Saving Trust for

energy efficiency being SEDBUK A rated with a NOx class 5 rating

- the best possible.

The Flexicom is incredibly easy to install with a pre-fixing jig and

‘pull-out’ electrical connections block, which means you don’t have

to remove the front case during installation or commissioning.


Glow-worm’s unique ‘Continua’© electronics allow the Flexicom

NEW Flexicom ‘glide down’ plug in timer

A brand new development for the Flexicom cx is the simple but

effective plug in timer. One simple push and the clock glides in to

position. Set the time to your requirements and another gentle

push hides the clock from view inside the base of the boiler.

The Flexicom clock accessory simply clips in to this imaginatively

designed, glide down casing and there is no need to remove the

case to fit it. An optional extra on all Flexicom cx models, it

provides the functionality of an electromechanical timer built in

without the need for external controls or extra wiring.

The only time the homeowner sees the timer is when they are

setting it. At all other times it is tucked up neatly inside the case

so the Flexicom cx retains its stylish appearance.

Flexicom Combi Controls

Brand new from Glow-worm are the Climastat, Climapro and

Climapro RF. This range of intelligent controls is totally compatible

for use with the Flexicom cx and very easy to install.






All Glow-worm controls are intelligent. This means that

they talk to the Flexicom cx adding an extra level of intelligence to

the modulation built into the boilers. This advanced level of

intelligent modulation keeps the room temperature totally

constant, providing better room comfort and makes the system

more efficient.

Room temperature is kept totally constant with a

Glow-worm control

The Climastat, Climapro and Climapro RF all operate on low voltage

and have simple wiring connections so there is no worry about

Part P compliance when installing a Glow-worm controller with a

Flexicom cx.

the controller talks to the boiler using radio frequency technology.

This means there is no need for any wire to link the controller up

to the boiler. No taking up flooring, no threading wires around the

room - just a clean, tidy and easy installation with a receiver that

wires directly to the Flexicom cx.

Flexicom hx Open Vent Boilers 12-35kW

Ideal for most homes, from apartments to 5 bedroom detached, the

Flexicom hx provides a large supply of hot water through a compact

just the Glow-worm range, in open vent or sealed systems.

Our cylinders are incredibly robust and built to last. Each

manufactured from high grade stainless steel, with laser welded

seams and guaranteed against perforation of the steel shell for

25 years.

But most importantly, all Glow-worm cylinders have excellent

insulation that achieves heat loss as low as 1.7kWh and a high

recovery-heating coil that provides recovery in as little as 20

minutes.

Available in six sizes 115, 150, 175, 200, 250 and 300 litres, they

are suitable for all sizes of property from small single bathroom up

to a large two bathroom property with ensuite shower room.

Plume is the vapour trail that

is seen coming from the front,

back or sides of a house when

the flue gas temperature

drops below the dew point. It

can happen with all boilers,

but is more significant on

high efficiency condensing

boilers.

Plume is not harmful but can be viewed as unsightly and can

potentially be a nuisance if it drifts across neighbours properties

or public areas. This is why Glow-worm provides the Plume

Management Kit.

The simple piping kit fits neatly onto the horizontal flue of

any Glow-worm high efficiency boiler installed in the UK. The kit

enables the plume to be exhausted further away from the flue

duct, reducing the visual impact of the vapour trail.

The Plume Management Kit can also be used to overcome many

more site issues. The kit can be extended to a maximum of 6m in

length and can be directed around ledges and other obstacles to

easily achieve the minimum clearance required on installation

without having to do the costly and difficult job of relocating

a boiler.

• Compatible with all Glow-worm Flexicom models

• Siting on wall face or above the eaves of a building

• Can be retro-fitted to any existing Glow-worm

High Efficiency installation

• Additional elbows, bends and 1-meter extensions available

• Simple push-fit connection

• Available in black or white to match rain water fittings

Condensate Pump

Unlike old standard efficiency boilers, High Efficiency Condensing

boilers produce water in the form of condensate as a by-product

of operating more efficiently. This is a great benefit for the

environment, but can make installation more difficult in places

with restricted access to a waste drain pipe, like the basement.

To remove this problem and enhance the siting flexibility of the

Flexicom cx, hx and sx, Glow-worm have produced a condensate

pump to collect the condensate from the boiler and pump it back

into the waste system.

The Glow-worm Condensate Pump is the smallest available in the

UK, being smaller than a shoe box and operates at maximum

efficiency, with the reservoir pump discharging the condensate in

one go when the fill level is reached rather than as a continuous

operation. In the unlikely event of the Condensate Pump becoming

too full, the overflow safety switch will shut the Flexicom down and

the pump’s LED display will go red indicating a fault.

• Smallest condensate pump in the UK

• Compatible with all Glow-worm Flexicom models

• Vertical pump height up to 4m

• 6m discharge hose for connecting the pump to the waste

water system

• Over flow safety switch

Ultrapower sxi High Efficiency System Store 100|170 Ltr

30kW High PerformanceSystem Store

The new Ultrapower sxi floor standing High Efficiency boiler has

been designed for the larger new build property. It provides

endless hot water on demand thanks to the innovative shift load

storage system. Available in two models 100 and 170 litres, the

Ultrapower sxi generates hot water whenever a tap is turned on

and by drawing on the internal storage system at the same time it

can rapidly deliver up to 170 litres of hot water.

Fitted as standard is an built-in bypass, filling loop, 2 stage frost

protection and anti seizure controls. Extensive flueing options are

available, and the Ultrapower sxi is also fully compatible with both

the Glow-worm Plume Management Kit and Condensate Pump.

for Glow-worm controls, designed for theUltrapower sxi

Ultrapower sxi High EfficiencySystem Store

The impressive hot water performance of the Ultrapower sxi is

achieved thanks to its innovative storage system which allows

the generation of endless hot water on demand.

Unlike an indirect cylinder the Ultrapower sxi heats the water

stored in its cylinder directly, resulting in a much faster reheat

time compared to that of a conventional indirect cylinder.

Hot Water Performance

The Ultrapower sxi re-heat time is approximately 10 minutes for the 100 sxi and 17 minutes for the 170 sxi.

As hot water is drawn from the store of the Ultrapower sxi it is

automatically replaced by the boiler, by doing this the

Ultrapower sxi can provide the equivalent hot water

performance as a much larger conventional indirect coil cylinder.

3

True on demand heating andhot water from a Combi

Stylishly designed

with an orange

back-lit display, the

inbuilt controls of the

Ultrapower sxi provide

technically advanced

inbuilt system control.

The adaptable inbuilt programmer provides 7 day or 24-hour,

single or two channel control for the central heating and hot

water pre-heat function. The simple push button controls, cut &

paste and advance functionality mean that it takes seconds to set

and alter any programmes, providing the homeowner with as

much or as little flexibility as they need.

2 Min 4 Min 6 Min 8 Min 10 Min

The Ultrapower sxi also utilises a much smaller hot water cylinder

than a conventional system boiler, but because the boiler

recharges the cylinder as the hot water is being drawn off, it

means the Ultrapower sxi provides the same hot water

performance as a much larger indirect cylinder.

Another major advantage is that unlike an indirect cylinder, once

the hot water store of the Ultrapower sxi has been depleted the

boiler operates as a normal combi, which means that the

homeowner never runs out of hot water.

notes

• This boiler must be installed by a competent person in

accordance with the rules in force in the United Kingdom.

• No secondary domestic hot water storage is needed.

• When domestic hot water is required, the heat exchanger

heats the mains cold water directly, ensuring a rapid response

time from turning on a tap to a continuous flow of hot water.

• In areas where the water hardness is more than 200mg/l, it is

recommended that a proprietary water conditioner be fitted in

the cold water supply to the boiler. A non-return valve must be

fitted to precede the water conditioner supply.


* Increase to 25mm clearance from combustible material.

† A removable compartment door can be placed at least 5mmin front of the appliance.

Ultrapower sxi Controls

Introducing the Climastat, Climaproand Climapro RF

The Climastat, Climapro and Climapro RF are Glow-worm’s brand

new range of intelligent controls, each being totally compatible

with the Ultrapower sxi. Whether you are adding controls to the

Ultrapower sxi because it is difficult for the user to reach or

providing extra control and functionality, Glow-worm have the

totally compatible, easy to install solution.

Totally intelligent controls

All Glow-worm controls are intelligent. This means that Glow-worm

controls talk to the Ultrapower sxi adding an extra level

of intelligence to the modulation built into the boiler.

This advanced level of intelligent modulation keeps the room

temperature totally constant, providing better room comfort and

makes the system more efficient.

When used with an Ultrapower sxi, the Glow-worm control

automatically overrides the inbuilt digital control so there is no

need to disable it. All controls use 24V power supply and a simple

wiring connections, so there is no requirement for Part P when

installing a Glow-worm control with an Ultrapower sxi.
