Case Studies

Case Study - Oxfordshire

The INSTALLER contacted Thermal Earth following the original specified heat pump was declined permission to connect to the electricity network. The fixed output heat pump's starting current was too high for the grid. This jeopardised the whole scheme as the cost from the DNO was £100K+ to upgrade the supply and the client had already drilled 14 x 100m boreholes. MasterTherm's Inverter Brushless DC (BLDC) compressor with ZERO starting current was an obvious option and following submission of the paperwork to the DNO permission was granted without the cost of upgrading the electricity supply.

The system compromises 3 x MasterTherm AquaMaster Inverter 22kW - totalling 66KW with 1 x 1000 litre hot water cylinder and 1 x 1000 litre buffer tank providing heating water to a low temperature underfloor heating system and indoor swimming pool.
