Hey guys. Merry Christmas.
I'm looking to make one of my showers a "Hot water on demand" setup. Any recommendations on what the best units are?

Are you thinking electric tankless or gas (natural/propane) tankless?

Kerry, I am a Sr. Service Tech for the gas company. Most of the builders in this area install Rinnai tankless water heaters. They come in various types. There is one model that has a three stage burner, varying the amount of gas used according to the amount of water being used at the time. They can be installed in a closet, basement, or on the outside wall of the house. I have never had a trouble call regarding a tankless. They seem very reliable. If you have one installed make sure the plumber uses a correctly sized gas line. The only problems I have seen come from too small of a line. Depending on the delivery pressure from the meter and the length of the run you should have a 1 or 1 1/4 inch line. The only other thing is you must use a special stainless steel vent. The cost is more then a tank water heater but from conversations with customers the cost of operation is significantly lower. And the instant and continuous hot water is great. Found the website www.rinnai.usHope this helps. |

My son had one of those Rinnai tankless heaters put in his house and he loved it. Cut his gas bill way down he said. From what I have been told the electric ones are not that efficient.

Yeah, stay away from the electric types. Bosch also makes a gas fired tankless, but all the plumbers I have talked to say they are not very reliable units.
