"Best Waterless Tank Heater on the Market"

Rinnai was The choice of a high end builder here in California. That’s impressive!

"I had a 4 year old home ( built new); It had Three Rinnai water heaters. One failed. Estimate to take apart and fix 3,000-4,000 but if I bought a new one for $5,000+ I would have new warranty and new model is easier to service. I was still under warranty for parts, the estimate for repair was mostly labor--it was a BAD design if it takes that much labor to fix under warranty. I bought Rinnai again due to other two Rinnai units-but not happy to do so."

"Tankless water heater "

BBK Oct 11, 2018

5.0

Quick heating and ease of temperature regulation makes this a great product. B

"It was a fair amount more to install than just replacing the hot water heater, but it has significantly lowered our utility bill. No doubt it will pay for itself, and the endless hot water is very nice. "

It is nice to know we are not heating 55 gal. of water 24/7 even when away on vacations, weekends etc.

"I had to adjust to how it works"

Homebody Jul 28, 2018

4.0

Having a water heater outdoors, taking up no storage space in the house is a plus. Using energy only when you are actually wanting hot water is a plus. But, having to run a faucet for ages and ages to finally get delivery of hot water is a negative. You may be saving on energy but wasting lots of water.

Continuous hot water. Had it for 5 months works fine. Had to make a slight adjustment in the beginning as the water turned hot, then cooler, then hot. Small adjustment corrected the problem.J R

"Working well so far."

Bothell Jul 23, 2018

The on-demand system certainly saves space. The time from turning on the faucet to having hot water has not changed noticeably and the temperature of the water is good. We haven't used it during a winter yet, so we are still waiting to see how it performs then.

"Good but has some issues"

Sparky Jul 20, 2018

Having unlimited hot water is great, bus sustaining a minimum flow rate is not only a challenge but a waste of water.

"Gas tankless water heater"

Jupiter Lady Jul 20, 2018

5.0

The gas tankless water heater installed in our newly built single family home by Toll Brothers Builders seems to be performing satisfactorily. At first when we heard that it would be installed on the outside of House we were concerned about the effects of Florida weather on the water heater. It appears to be working fine.

"Great Water Heater"

This unit has been trouble free for going on a year now. The hot water temp is stable and water pressure is adequate for 2+ showers running at once.

"Endless Hot Water"

Never suffer with a cold shower again - Rinnai's tankless ensures everyone gets all the hot water they want. No more yelling at the kids to shorten their showers.
