Project completed in October 2023
The homeowner was concerned about the reliability and efficiency of the property’s outdated heating system. Menai worked closely with them to design and install a modern solution tailored to their needs funded by the ECO4 grant. Since the upgrade, the landlord has described the home as “future proof,” highlighting the long term benefits of the new system.
EPC rating of the property went from a F29 to B89.
Scope of work
10, 405w JA Solar Panels
16kw Riello Air Source Heat Pump
75.5m of therma bead cavity wall insulation
A total of ten 405W JA Solar panels were installed across the west and south facing roof sections. To maximise solar generation, some panels were mounted on the flat roof using a roof mounting system. The solar panels were paired with a 7.5kW GivEnergy battery, neatly located in the plant room, allowing the home to store excess electricity and use it when needed, improving self sufficiency and reducing reliance on the grid.
We installed a 16kW air source heat pump at the rear of the property. This works with a 200L hot water cylinder, also located in the plant room, to deliver consistent heating and hot water throughout the home. Inside, 17 new radiators were installed, each fitted with thermostatic radiator valves (TRVs) to give the homeowner control over individual room temperatures.
75.5 metres of ThermaBead cavity wall insulation was pumped into the home’s external walls, significantly boosting heat retention and comfort.
This project is a great example of how the ECO4 scheme, combined with expert design and installation, can make homes more efficient, comfortable, and ready for the future.
