dual water heaters: parallel or series??


Had the same arguement w/ a co-worker. His take on it was, "There's no way to ensure that they will be used equally." My response, "Rephrase, 'There's no way YOU can ensure they will be used equally... I know how to use my tape measure."

Thanks Micheal Thomas... I'm gonna print out that bulletin and slam it on the windsheild of his van in the morning.

I would wonder if using it as a warmer as I do would still cause this Problem... Basically I put the first water heater on Med and second on hot so they are both still being used all the time

Doc,

Personally I don't think it is a concern if you turn the first heater back. The question is what is the Delta T.... normally this is approx 20 degrees difference. Not really sure there.

plumber26, tell your coworkers that you can't fight physics. Many have tried and lost.

It's always hard to teach old dogs and young pups!

Question

Ok boys.... What would you do?

Just failed an 8 year old AO smith 66gallon electric

Wanted the tax credit and save on money, so installed the GE Geospring 50 gallon unit.

Running out of hot water and water pressure is much less on the hot side, I'm assuming the GREEN GEOSPRING has a flow restriction.

I like the geosprings features, warrenty, low cost... I'm thinking about getting another Geospring and plumb it parallel. This should double out amount of storage, increase hot flow rate, and still be cheaper to operate per year than a single 100 gallon. Agree or disagree with my gameplan?
