Topic - Air source heat pump

Philip on 18 Apr 2014
Hopefully moving house to somewhere we will stay for a very long time. I've been through this exercise with my current house where we never intended to stay more than 5-10 years.

I want to install central heating to a property without mains gas. It needs to be a system that works without someone there (not a coal/log fire and back boiler). Cost not a concern, if payback is good (considering renewables).

I'll be removing storage heaters, and disconnecting coal fire back boiler. (Although eventually this will become a log burner and I would later like to couple this in to help provide hot water).

Space inside is not easy, although it's a large house, there is a hot water cylinder, but I don't want an internal boiler if I can avoid it. Space outside is almost limitless. Roof is E and W facing.

I originally though oil, external boiler. Probably combi or unvented tank. Great mains water pressure. But I'd be interested from anyone who's fitted a heat pump either on its own or with some other heat source. I don't want downstairs underfloor heating as it means ripping up expensive flooring - but I see Dimplex do radiators that work at 40 degrees C.

My only worry with heat pump is that I'll be using a lot of electricity if I have heat pump + 1 or 2 electric showers + electric cooking. In my current house the electric boiler and shower are connected by relay to prevent simultaneous use.

Anyone on here tried biomass?
