Mark P Posted October 28, 2006 Report Share Posted October 28, 2006 I came accross this on todays inspection, first time I've seen a water heater used for this purpose. As best I can tell the pipes run under the floor of 1 bathroom and shower to heat it up , the rest of the house is heated by a forced air furnace. There is a circulating pump, pressure/temp gauge, 4 pipes running in/out of floor (bottom left corner). A couple of red things behind the gauge that I don't know what they are. If there is something wrong with it I don't know what it is, but thought I'd share it with the TIJ community. Anyone have a link to an article that will educate me on this set up, or even what the proper name is.

kurt Posted October 28, 2006 Report Share Posted October 28, 2006 The couple of red things.... Bell & Gossett pressure reducing valve & an inline B&G T&P valve. I also like the little glass beaker under the tank T&P pipe.... Quote Link to comment Share on other sites More sharing options...

Chad Fabry Posted October 28, 2006 Report Share Posted October 28, 2006 I guess the proper name is "boiler". I'm seeing more and more water heaters employed for space heating. With the proper controls and safety devices, I have no objection. It's easier to plumb w/ copper tube than it is to install duct work.

hausdok Posted October 29, 2006 Report Share Posted October 29, 2006 Hi, Here's a 1998 article by a veteran plumber who uses hot water heaters for radiant heat. OT - OF!!! M. Quote Link to comment Share on other sites More sharing options...
randynavarro Posted October 29, 2006 Report Share Posted October 29, 2006 I'd like to do some more research on water heaters beings used for hydronic systems. I know that most manufacturers make units that are capable of doing both but I don't know how to tell the difference if I see one on a normal inspection.

hausdok Posted October 29, 2006 Report Share Posted October 29, 2006 Hi Randy, The most noticeable features that I see are the exposed lugs on the sides of the tanks where hydronic systems are supposed to connect. That and the fact that most are usually at least 65,000 Btu/Hr vs. the 40 - 45,000 for the typical water heater used for domestic hot water. I see te Bio-Radiant systems frequently and most folks I know who've had them love them. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
swolsen Posted October 29, 2006 Report Share Posted October 29, 2006 I have a customer that has a WH that is used as a radiant heating system for a sun room. It has a mechanical vent for exhuast and a circulator that pumps the heated water through PEX tubing in the slab. Pretty slick. Quote Link to comment Share on other sites More sharing options...

There's the secondary heat exchanger models for those w/the dough, but I've seen completely wonderful hydronic systems using a cheap GE someone picked up @ Le Depot de Maison for $180. At first, it offended every sensibility I have, but after talking, looking, & thinking about it, why not? Quote Link to comment Share on other sites More sharing options...
