EcoRenovator - View Single Post - Combined solar plus heatpump central heating

..my latest project..

Last year I built a heat pump system and connected it to my central heating system. The results were spectacular to say the least. I saved in the order of 1500 euros on heating oil for an investment of about 100 or so euros.

See http://ecorenovator.org/forum/geothe...ks-mods-3.html

Well, having acquired a couple of 100L vertical mounted water tanks during the year (one top fed, one bottom fed, couldn't have wished for a better combination!) and a couple of solar hot water panels with blown pipework (an easy enough fix just a bit of brazing) the logical thing to do was to see if I could add solar heating to the system as well.

So I have put a system together, one tank (the left one in the photo) connected to the solar panels, the other tank connected to the dual compressor heat pumps (there are actually 3 but...) - see http://ecorenovator.org/forum/geothe...at-pump-2.html

I've just got to mod the controller now so it runs the solar as well as the heat pumps and commission the system. Just in time for winter although it seems to be later coming this year.
