Infloor liquid heating

Body

A little progressOn top of a 40 ton load of crushed limestone well tamped down, spray foam insulation was applied to a thickness of75 to 100 mm thick.Steel re- bar mesh grid was then laid down. To that, the various circuits of the floor heating tubes are installed, held in place with ny-ties.We will be heating the water based liquid with an electric heat pump, as yet to be purchased.Europeans are far ahead of the heating companies in North America regarding efficiency, I have been told. Sweden uses this type of system, as does Austria, and Germany. It is now being used in the UK too.Although they use 250 volt 50 htz systems, it may be possible to convert from single phase 220volt 60 htz?My issue is to either hack an air to air system to be able to run liquid, using heat exchangers, or buy a European system, as North American systems are not geared for in floor heating, unless you pay big money. The outcome is fairly uncertain, speaking with people who have gone the North American route.I also wish to burn wood, as the property produces, purhaps, five cords a year, with just windfalls and branches, that must be cleared and disposed of.Supplimenting the heated floor, or hot water, seems a good idea in winter.I have not as yet even addressed solar power, electric or thermal, but in any case must get the infrastructure for the apparatus in place. The fundamental item is the heated radiant floor. I need this workshop to continue my research.The building is to be my workshop, studio laboratory space. It needs to be heated. Another Winter is coming!Cheers Warren
