I really don't know the ins and outs. Frankly, I'd never considered a
tankless, but a municipally funded nonprofit agency offered to install
it in my house for free. I qualified for the program, they are dedicated
to energy conservation and ecologically sound home improvment
technologies, they'd never installed a THWH, evidently wanted to do so,
and they had some extra money at the end of their fiscal year, ended
June 30. On top of that, I had a bit of a problem running a vent from my
dryer out the wall because of the old tank water heater I had was in the
way. It was about time to replace the water heater, and they got the
idea to install a tankless, and I figured "what do I have to lose?"
Honestly, I'm not overjoyed. I guess it's OK. I won't have the whole
story until I live with it a year, through all the seasons. It doesn't
furnish hot water unless the flow is at least .5 gallon/minute. One
effect of that is that you either use that much flow or you turn the
spigot off. That's because any water coming from the heater at a slower
rate will not be heated at all, so when it gets to you, it will be cold!
Right now (summer), I'm mainly using it for taking a shower, because the
cold water is warm enough to do my dishes, unless I have a lot of
dishes, in which case I use the hot. In my situation, I'm very unlikely
to have hot water flow to the point where the heater can't furnish the
supply needed. I would never have installed it if I had to pay for the
thing, that's for certain. I actually expected I'd have to buy a tank
heater myself and install it myself. One thing I plan on doing (and
could have done with the tank water heater) is insulate the hot water
pipes, at least the ones I use the most.
