Hot water heating with a gas boiler

Mark Hunt

21 people don't "drop in", they ARRIVE!! LOL!!!

If you use the indirect, you will definately have more HW that you and your husband could use, but the boiler would only run when the water needed to be heated AND the indirects have such a low stand-by loss the boiler would not cycle all day long.

Buying multiple units seems more wasteful to me as opposed to buying one unit sized for the worst case scenario. The extra plumbing PLUS the extra equipment would cost more than it would to operate one large indirect for MANY years.

A 60 gallon indirect will cost less to operate than a 40 gallon direct fired unit.

Hope this helps.

Hot water heating with a gas boiler

Hi, We are remodeling (completely redoing) about a 4500 sq ft home. We are doing baseboard hot water heat in the basement and Wisbro floor heat in the main floor. Most of the year it is just my husband and I but a couple of times a year our 5 children, plus spouses, plus 11 grandchildren drop in. We are trying to decide how to heat hot water. Our heating contractor wants to put in a 60 gal storage tank and use the boiler to heat it...great but I don't think the two of us can use 60 gallons and then we have to run the boiler all year. BUT, when everyone is here, we are a water using menace. Help. Should we do indirect, coil, tankless, recirculating, multiple heaters???? I'm confused.

Thanks. Stacy

Stage 2

This is a question to your question. Does anyone know how could stage a couple of instantaneous water heaters. Stage one would operate, in the northeast anyway, at roughly 3-1/2gpm. That would be good for you and your husbands needs. Only heating when you need water. You could stage in a second heater to supply up to 6-7gpm when the family arrives. I would think this could be possible with todays technological age.

answering my own question

I thought of one way to answer my own question to yours. You could isolate the second unit with ball valves, closed when it is you and your husband, only allowing flow through one unit. Open when the family arrives allowing flow through the second unit. That is the simple mechanical, however, still looking for suggestions on controls that may be able to do this.

P-U!!! Have you ever smelled a WH that has sat for a few months not used?? Boil some eggs and let'em sit in a warm boiler room...yuck! Not to mention the bacteria that could breed in a stagnant tank...ask ME, why don't cha! (see leigonella thread)

might want to go with...

a Large Buderus indirect..they are insulated to beat the band...add an anti scald valve..have a zone valve on the hot water line...:) shut it off an on with a remote control:) that way, you insure they get out of the bath room ...lickty split

you ran away from home and they Tracked you down ...:) What can i say?

*~/:)

call it..a COLD IDEA ...

you might even fid it would work on your existing indirect ....
