The Strategy
New Systems3 & 4 No panels of PVProviding 1955kWh/y of Primary Energy
System used- Dimplex DCPVM250P6C-30
Following an initial review and a more detailedDEAP analysis the heat pump and smart radswere removed - some minor upgradingworks to the existing boiler still produced thedesired result without additional cost to the client
There is an option to replace the existing gas boilerwith a more efficient Heat pump under futureupgrades or if the existing boiler fails.
