Ground Source Heat Pump - Intro

I am hoping this is going to turn into a regular feature with updates from time to time concerning this new project of ours. Essentially we are going to have a Ground Source Heat Pump (GSHP) as the main energy efficient supply for home heating and partial hot water supply.

The concept of a GSHP is explained here. We are going for a horizontal closed loop system which will only supply heat as cooling (air-conditioning) is not required in the UK.

In a few weeks time I will be uploading some photos of the underfloor heating installation. Unfortunately I won't be able to show the external loop installation, but the image below does show where the input and return pipes pass down through the floor (they are the large black pipes to the left of the heat exchanger).

So why GSHP? Well, it's all about economy. With energy prices soaring, the future is in efficient technology that combines the provision of cost effective heat and high levels of insulation.
