  • Contemporary self build “Glass House” project benefits from Integrated Air Source Heat Pump and Solar Photovoltaic Installation.

    10kWp Staffordshire Farm

    The Glass House is a contemporary self build project located in Mansfield, Nottinghamshire. The owner is an experienced construction professional who is committed to integrating a thermally efficient house, with an energy saving heating technology and a microgeneration system.

    CTS Renewables completed a full on-site assessment, produced heat loss calculations using building schematics and consulted with the customer on their exact requirements and any limitations due to the building design.

    As the property was off mains gas and was a restricted plot size, it was agreed that the building would be heated using an Air Source Heat Pump distributed via a combination of underfloor heating to the ground floor and radiators on the first floor. Additionally a solar photovoltaic installation was specified to support the electrical running cost of the ASHP alongside the house requirements.

    The heat load of the building required the installation of two heat pumps. The system was designed to split the house into two zones with different flow temperatures. A 16kW Samsung RC160MHXEA unit supplies the underfloor heating via a Gledhill 100 ltr buffer tank at a maximum flow temperature of 45°C and also the hot water through a Gledhill HP250IND 250 ltr indirect, unvented cylinder. A 9kW Samsung RC090MHXEA supplies the radiators on the first floor at a maximum flow temperature of 55°C.

    The Samsung weather compensation feature varies the heating flow temperature according to external conditions maximising performance and efficiency.

    A 4kWp Solar Photovoltaic system was installed using 16 Trina TSM-250PC05A black framed polycrystalline modules. The customer was keen to reduce the aesthetic impact of the solar PV panels on the roof of the property. The Trina panel provided the best match to the blue/black roof slates.
