Denray Posted August 22, 2013 Report Share Posted August 22, 2013 OK, I know nothing about this stuff. The hot water for the house and floor heat seems to be all out of the same boiler. Only fault I see is that the TPR drains have some uphill portions. The rest I be ignant on. See any problems. The old, 2004 boiler was replaced in 2011.

kurt Posted August 22, 2013 Report Share Posted August 22, 2013 I just gave the pics a quick glance, but I think you're fine. It's a boiler with a secondary heat exchanger for domestic water heating and a reservoir/holding tank for domestic hot water. I see these systems in various forms; they're great. This one might have some fine tuned stuff I'm too tired to see right now. Quote Link to comment Share on other sites More sharing options...

kurt Posted August 22, 2013 Report Share Posted August 22, 2013 Actually, on second glance, the 2nd heat exchanger is in the big tank, not the boiler. It warms up the water in the tank. Still ok though. Quote Link to comment Share on other sites More sharing options...
Denray Posted August 22, 2013 Author Report Share Posted August 22, 2013 When I was starring at it all I was thinking the boiler hot water was going directly into the large tank, duh. That seemed dumb. Then I couldn't figure out how that pipe mess was going on there. Realizing there is a heat exchanger in there makes it come together. Thanks Kurt. It's terrific that you guys are so helpful. Quote Link to comment Share on other sites More sharing options...
Hearthman Posted August 23, 2013 Report Share Posted August 23, 2013 You have a condensing boiler with piping to an indirect tank for potable hot water followed by a water softening system behind it. Can't tell much but a few points other than the already noted discharge piping issues: -low voltage wire sharing the same Romex clamp. Should enter at a separate point. -Can't see a backflow preventer. looks like just a fill valve. -can't see but the cold potable water feed must have a check valve downstream of an approved isolation valve on the indirect -thermal expansion tank should have a dedicated isolation valve so it can be tested or replaced as needed. any more pics?
