Case study: Grove Springs Eco Home

Kensa supplied Grove Springs with two water source heat pumps to provide the space heating and domestic hot water production at the eco friendly property, significantly lowering the carbon footprint.

The inclusion and integration of new eco friendly technologies has resulted in reducing the carbon footprint to the lowest level achieved by project managers Courtyard Developments Limited and Eco Heat.

Grove Springs benefits from the highest quality design and building standards.

The inclusion and integration of new eco friendly technologies has resulted in reducing the carbon footprint to the lowest level achieved by project managers Courtyard Developments Limited and Eco Heat.

This has been achieved by moving away from traditional fossil fuel technologies and installing a renewable energy plant to provide an eco-friendly heating solution that lowers carbon dioxide emissions and overall running costs.

Kensa Heat Pumps supplied two water source heat pumps to provide the space heating and domestic hot water production at Grove Springs.

A Kensa 16 kW Twin Compact ground source heat pump supplies the space heating to the property. Located in a plant room the Kensa Twin extracts heat from the property’s top lake by circulating a solution of glycol anti-freeze and water around a closed loop pond mat system. The pond mats comprise of three separate 250m long 32mm tube pipes, which are submerged in the lake, and a 100m long 50mm pipe running between the lake and the plant room.

The glycol solution within these loops absorbs heat energy from the water. The lake manifold balances the flow from the pond mat loops and allows a combined single circulation to pass through the heat pump where heat is extracted and transferred to an underfloor heating system.

All rooms at Grove Springs with the exception of the gym are heated by an underfloor heating system, supplied by the Kensa Compact heat pump.

Grove Springs is a large house (630m2) and as such the underfloor network has seven manifolds with electric controls that distribute and control the heating. Each room has its own pipe network and can be individually controlled by a room stat that sends messages to a manifold where actuators open and close allowing the warm water to circulate in to that rooms’ pipework.

Each manifold and room stat is electrically connected to a central control pad.

Grove Springs’ domestic hot water is generated by eight Velux solar thermal panels, supplying two cylinders which together hold 610l of hot water that service the five ensuite bathrooms and handbasins.

In the autumn and winter months when the solar panels are less efficient, the dedicated hot water 7kW Kensa Single Compact ground source heat pump tops up the temperature of the hot water cylinders.

In addition to the solar thermal panels, the property also has sixteen solar photovoltaic panels. These panels collect solar energy and transfer it into electricity that is used by the house.
