HOT WATER SUPPLY
GENERALIn order to comply with functional regulations XA2 Contained in Part XA of the NBR the following guidance is provided: Accordance with Table 2 and 5 of SANS 10252-1:2004.Requirements for water installation in buildings shall be in accordance with SANS 10252-1 and SANS 10254.All hot water service pipes shall be clad with insulation with a min R value in accordance with Table 1.Thermal insulation if any shall be installed in accordance with manufactures instructions.
THERMAL INSULATIONPipes, fittings and components shall when necessary be protected against freezing. The insulation provided shall be appropriate to the min. temperature that can be expected in that geographical area.All exposed pipes to and from the hot water cylinders and central heating system shall be insulated with pipe insulation material with a thermal resistance in accordance with table 10. R value of 1.00 for 15mm pipes.Insulation shall be protected against the effects of weather and sunlight, and be able to withstand the temp. within the piping and achieve the min. total r value given in table 10:Table 10Internal Dia of pipe >80 .......... Min R value< 80 ........................................ 1.00>80 ......................................... 1.5Hot water vessels and tanks shall be insulated with material that achieves a min r value of 2.0. Note: to achieve this value, insulation in addition to the manufacturer’s installed insulation might be required.Insulation on vessels, tanks and piping containing cooling water shall be protected by a vapour barrier on the outside of the insulation.The piping insulation requirements do not apply to space heating water piping located within the space being heated. Where the piping is to provide the heating to that space or encased within a concrete floor slab or in masonry, such piping shall comply with this Part of SANS.Piping to be insulated includes all flow and return cold water supply piping within 1m of the connection for the heating or cooling system and pressure relief piping within 1m of the connection to the heating or cooking system. Where possible the length of pipe runs shall be minimised.After thermal insulation material has been installed, the ingress of moisture into such material shall be prevented. Note that roughness increases the effective surface area of insulation material and consequently, heat losses and moisture increase the thermal conductivity of the material.
HOT WATER SYSTEMS CALCULATIONCalculated as per SANS 10252-1:2004 (hot water system to be endorsed by specialist):
Type of accommodation: Dwelling / House
Daily capacity in litres: 55 - 110 l/day
Number of people per day: 4
Assumed daily water consumption in litres: 440 l/day
Assumed daily hot water consumption in litres: 220 l/day
Assumed annual hot water consumption in litres:80 300 litres Based on daily design occupancy
50% of daily hot water in litres: 110 l/dayProvided by means other than electrical resistance heating
Insulation Requirements
Internal Dia of hot water service pipes: <80
Min R-value 1.0 as per SANS 204
Min R-value for hot water tanks 2.0 Insulation may be required
Hot Water Calculation as per SANS 10252 - 1
Estimated daily demand for hot water: 110 l/day
Capacity: 250 l storage tank
All hot water pipes must be installed with thermal insulation of minimum R-value 1.0
Conclusion: The design complies with the requirements of SANS 10400 -XA-2011 and SANS 10252-1:2004 for hot water calculations

Assume the lights are turned on between 17:30-21:00 each day:
That is the following number of hours per day: 3.5 hrs/day
52 weeks X 7 days X 3.5 hrs/day = 1 274 hrs/annum
