Tankless Water Heater

Jammer_2 Member Posts: 7
Looking for any advice/opinions from the pros on tankless water heaters. Are they worth it? Will they save energy dollars? Any problems with them? What are good brands? electric vs. propane? My home is going to have 2 1/2 baths and is located within 30 miles of Harrisburg, PA.

    I feel that propane would be the most effecient way to go and the fastest recovery on hot water. there are many brands out there bosch and rinnia put out a few brands that you can look at.

    Rinnai's are excellent! Be aware if you are from an area with very cold groundwater such as we have in Alaska you may want to consider the commercial models. They are only a bit more expensive and have a higher temp output ( 140* on residential up to 160* on commercial models. Max output with our groundwater temps appears to be in the neighborhood of approx 4 g.p.m.- Mr Ed

    On a Rinnia unit the only difference between the res. and com. unit is the com. unit is factory set for a high temp. water. One Rinnia unit is good for up to 2 to 21/2 bathrooms as long as there isn't a whirlpool tub, then I would recommend you put in 2 Rinnia units. Very dependable as long as there put in right by the installer.

    I have very good luck with the rannai heaters. I can't stress enough that they be installed correctly. Take special caution to properly size the gas line. And yes the incomming water temperature makes all the difference in the world as to their performance.
    When they are used for correctly to make domestic hot water the work fine

    I'm currently using a Toyatomi kerosene on-demand for domestic hot water - works great and is very efficient! (88% according to the Toyotomi web site). This unit produces 148,000 btu and I have never run out of hot water.
