Underfloor heating for a manor house in Hertfordshire

Better Planet was selected to design, supply, install, and commission a Ground Source Heat Pump System and Underfloor Heating in connection to this new build in Sussex.

Our involvement started with a room-by-room heat loss calculation allowing us to size the heat pump and design the underfloor heating.

Ground source heat pump and underfloor heating

Heat is collected from a field using 1.2 km of 40mm collector pipe. Groundworks using a trenching machine subcontracted by Better Planet. The collector pipes are connected to a ground manifold and two 63mm pipes connect the manifold and the plant room. Underfloor Heating throughout the property. A screed system on the ground floor and a dry screed system on the first and second floors.
