Hello, I’m looking for info/advice about installing a underfloor heating system in a newbuild house. It’s miles out in the country, sits in 15 acres of land, and with no mains gas and the price of oil being high and only going to get higher, the heat will be provided by a ground source heat pump. The favourite unit so far is a Worcester Greenstore 11kw ‘system’ ground source heat pump. Has anyone got any experience of this unit? The spec reads very good i.e. max heat to heating system is 65 C. with a 2 year warranty and 25 year life expectancy. I’m told it’s simple technology and not to be afraid but it’s a friends house and they know where I live, so it has to work and work well!
