Water heaters are not designed to be used as boilers.

Period.

If in

you need more than 140° temperatures, I too would consider a boiler.

There may be a few WH brands and models with 160° aquastats still available. The State Apollo is one. Some of the Bradfords came with high temperature stats.

Although not listed for such applications basic, non condensing, tank style, WHs are commonly used for low temperature low BTU demand systems.

The main reason being the upfront cost

If you start switching controls you assume all the liability should a problem arise, by the way. Be careful!

NO WATER HEATER IN PLACE OF BOILER

mike I can only speak from experiance that I had fixed a few small wet radiant systems up that were originaly installed with hot water tanks.
Even though the numbers said the tanks would produce enough BTU's they just couldn't bring the slads up to temp.
We ended up putting boilers in solved the problem.

I agree with the boys

I've used a couple for radiant applications. By the time all is said and done, you have piped out a whole boiler, but you are still stuck with a water heater that will not last as long...what do you really save THe HO in the end. I used a water heater once for two very small high temp baseboard zones. I had to change the gas valve add an aquatstat, spill switch. It wasn't worth it dude! Spend the money on a tiny Burnham or even Slant Fin makes a really tiny 2 section boiler perfect for these applications. Mad Dog

How many BTU's?/KW?

And perhaps more importantly How do you intend to deliver and distribute the requirement.....? and for how long a period of time do you need it to happen?.........those are just some questions you must ask yourself.........it is a little unlikely that a person can guess what you think is doable and a very real dose of what in fact is the actual reality. then ours is not the final say you will also have to get permission from the authorities having jursidiction, does it meet code in your state , county or burg. ...? that sorta thing. i have a water heater i use as a tool, i know what it can and cannot do. it may be you can dream up some other use for it though,that is within the realm of possibility...however at this momment you first need to get a grip on the first questions that i rolled by you.no one has asked you about maintinance either, that is something i belive is important thing to consider. The water heater i use is electric, for radiant space conditioning,during construction,it is modified slightly to meet what i need it todo.do to the relative temp differences of outside to inside the building ,for us, it "Works".in a radiant system,iwould not hesitate to have it available for a temporary back up sysytem, i am not making any claims here that it would be able to hold against the cold indefinitely.i am not a water heater sales man how long the tool is going to last ? i dont know...i only use it in the early winters ->spring it is drained...i have been doing that with it for about 5 years. oh . and it looks it!:) seems not every one respects it as one of my tools.today it is been on line since we poured cement in some realchilly temps.just before it went 40 below... the other day we poured gyp crete. i have no intention of running anything thru it for at least another couple weeks. however most likely it will be this tool i use to deliver very low water temps to the zones while i plumb the boiler.it could go colder this year.this is the first time i have used any anti freeze in it. the reason is that it was too cold not to. once it is 30 below running water into a slab might not want to come out the other end:) Trust me an experience youd be better off without .....so to use some newly discovered Weezbo Hydroglyphs on the applicabilities of water heaters as heat sources..........It only works if You Think it to.
