Case study: Enstone Manor, Oxford

Where there is a will there is a … water feature!

This sensitive renovation sources heating from a new cascade pond to supply sustainable and efficient heat to the grand manor house.

The new owner of this period manor house was determined to use renewable energy for heating the property due to the considerable running cost savings achievable.

The sizeable plot available meant a perfect solution lay in creating a new, large pond which could be used as both a heat source and an aesthetic cascade pond.

Three of Kensa’s customised plant room heat pumps were installed and commissioned by the clients’ own plumbing contractor. Kensa also designed an open loop system to capture the flowing water energy in the pond.

A submersible pump was positioned in the pond to pump water directly to the heat pumps, where the energy is absorbed and upgraded to a higher temperature of about 35°C to provide a heat supply for the underfloor heating system, installed throughout.

After leaving the pond and passing through the heat pumps, the water is then passed to an exotic new fountain and water feature, before draining back to the pond by gravity.
