elgato Posted February 9, 2007 Report Share Posted February 9, 2007 I have an inspection scheduled next week for a home that has a "electric hot water" heating system, as described on the MLS sheet. I am not familiar with a heating system like this. I expect that there is some sort of tank or apparatus where electric coils heat water, a pump, and distribution system. I would like to know what issues I should look for, other than any normal electric appliance. Has anyone seen these? or is there a site where I can read up on them? Thanks.

Scottpat Posted February 9, 2007 Report Share Posted February 9, 2007 Hi Greg, Sounds like it could be an Apollo type system. They work like the heater in your car. Hot water flows through a coil and air is then blown over the coil. I can't say that I have ever seen an electric hydro heating system, all I have seen have been gas fired. Well I checked the Apollo site and they only make gas units. So it's not that. Quote Link to comment Share on other sites More sharing options...
Terence McCann Posted February 9, 2007 Report Share Posted February 9, 2007 Hard to help with no specifics. There are a few different types of systems out there. How old is the home? If it's a conventional system just substitute a electric boiler for gas. Check the usual items such as electrical connections, contactors and the like for burns / discoloration, expansion tanks, backflow prevention, water makeup, circ pumps, zone valves - all the stuff that would normally go with a hydronic heating system. If you really want to go a step further you can amp out the elements too. Quote Link to comment Share on other sites More sharing options...
Bain Posted February 9, 2007 Report Share Posted February 9, 2007 You said home. Is it a condo or townhouse? Around here there are condo complexes with hydronic heat pumps. Each unit has an air handler, but there's a massive boiler/chiller that heats/cools the water that's circulated through the individual units' coils.

It still might be. We's got hyro-air systems out here that use electric water heaters. Probably not made by Apollo, but they work well. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted February 10, 2007 Report Share Posted February 10, 2007 With "electric hot water" listed, I would assume it is an electric boiler and would follow what Terry described above. I come across 1-2 a year. It seems they are becoming more popular with many in-floor radiant systems. They are usually wall mounted units. The (several) elements are about the same as you find in a water heater. They must be mounted plumb/level and a low water cut-off is usually necessary, because some of the baseboard or the radiant loops are well below the level of the boiler. I'll be out in your valley, a bit south of Lewisburg, late next week. Quote Link to comment Share on other sites More sharing options...
