Tankless water heater experience?

Hi,

We are considering a tankless water heater. Has anyone on the forum have
any experience with this? Particularly with regards to its efficiency for a
full household?

Thanks,
Chandana

Hi Chandana,

We have one in Falmouth, mainly because we often have visitors and after the
beach everyone can shower. It works great, (also energy efficient because
there is no need to heat water until you need it) If you have the capacity
for venting to an outside wall, I would have done it here, but venting was too
long

I'm not sure if it's the same thing you are talking about, but we have a
"tankless" hot water heater in our oil furnace, which we now only use for
backup (switched to electric "ductless mini-split" heat pumps a few years
ago). I think it's about a 3 gallon tank. It wasn't efficient for us
except in winter. During months when we didn't use the heat, the furnace
came on frequently to keep the 3 gallon tank of water hot. It consumed
about 18 gal/month, with 2 of us using the hot water fairly sparingly. A
larger tank holds the heat much more efficiently, with a smaller surface to
volume ratio.
We installed a 50 gallon GE Geospring hybrid electric heat pump hot water
heater 2.5 years ago and are very happy with it. You are welcome to come
over and take a look.

Hi Chandana,
I think John could probably answer any questions for you...

Chandana,

We placed 2 Rinnai systems in our house when we did our addition and have been
very happy with the decision. The only reason we put a second system in the
second floor was because of the shape of our house and the amount of time it
would take for the hot water to travel upstairs from the basement.

We have never had any problems with running out of hot water, water pressure or
maintenance. The system does need to be flushed periodically with vinegar
(Dan could show Chetan how to flush the system.).

Dan would be happy to discuss any specifics with you.

Good luck!
Tammy
