Help with on demand hot water heater

[RiverRat1]

Here's the water heater I'm having installed

I want to know how much it costs to run a regular gas water heater with a tank versus an electric with tank versus the one in the link above.

I read that gas are more to buy up front but in the long run cheaper due to lower utility bills. But the Energyguide I found in the unit says it costs $567/year to run. That seems high to me...Is it?

Mine will run on propane BTW

For a tankless, you want gas not electric.

Rinnai have a lot of problems. I have replaced the electronics in quite a few.

Love ours. We replaced two 55 gal has water heaters with one of those and it ONLY comes on when you want hot water. You do need to flush it with white vinegar to keep the lines clean. I do mine every couple of years.

I have the Rinnai RUR98e at my house.

It’s the only gas appliance I have, and my gas bill is about $30/mo on avg. In a 2.5 bath house with family of 4.

I love it thus far. I’ve only had it a few months, but we were already running out or 50 gallon water heater when we took successive showers.

I’d say tankless are definitely cheaper to operate overall, but I went from an electric tank heater to a gas tankless, so don’t really know the difference.

If you are really concerned with gas consumption, step up to one of the condensing models.
