Case Study - Ground Source Heat Pump Installation

Location: Kilkeel, Co.Down

This project demonstrates the design, supply, installation and commissioning procedures involved in the installation of a 14kW Alpha InnoTech Ground Source Heat Pump, 2 Panel VELUX Solar System and Underfloor heating.

When this client decided to build a four bedroom house on the outskirts of Kilkeel, they wanted to make its energy supply as sustainable as possible. They were interested in the conservation of energy and felt that wasting raw materials on heating was unnecessary when so many renewable energy sources were available. Having seen heat pumps in operation, they were very impressed, so when the opportunity arose to build a new house, they looked into the possibility of installing a ground source heat pump.

Kellys Renewable Energy Solutions worked closely with the client and the architect to ensure that this house was designed to maximise the efficiency of the heat pump. As heat pumps run at a lower temperature than normal central heating systems, it was advised that underfloor heating should be installed, combined with the right insulation in the walls, floors and loft to create an efficient heating system. To maximise further savings, the clients had a 2 Panel VELUX Solar Hot Water System installed, to provide up to 70% of their daily hot water requirements.

The location of the client’s home was ideal for a ground source heat pump as they had plenty of ground space which allowed them to dig horizontal trenches for the ground loops.

Following the installation of this system, the clients have noted how pleased they were with the level of service and expertise that Kellys Renewable Energy Solutions provided throughout the duration of the project. As a result, this house will use considerably less energy than it would have done without the heat pump and solar panels. Although the capital cost of installing a heat pump is higher to that of a conventional central heating system, the client believes that the environmental benefits make it a worthwhile and sensible investment.
