Tankless Heater

[werbo]

I am building a new house and am looking into installing a Tankless Water heater to supply hot water to the house and heat the infloor system in the basement. The supplier to the builders plumbing contractor is recommending a Navien CR-240A and closed loop heating box for the application. I have read up on the Navien in the forums here and it seems they have some issues. Can anybody recommend a brand and or system to use in this application. Originally the builder had quoted me on a boiler for the infloor heat and a Tankless system. The boiler seems to be a waste to me if I am gong to go with a Tankless system.

To give you an idea of the application the house is a 2700 sq/ft two story with 1500 sq/ft of developed basement (infloor heat). There are 3 1/2 bathrooms. I want a system in which 2 showers and one faucet can be used simultaneously.

Any advice is appreciated.

Thanks

some of our other members can give you more specifics, but the boiler with an indirect hot water tank sounds like the better option in your case.

Tankless hot water is nice if you Need the space, but if there are more than 1 or 2 of you in the house i'm not sure if the gas savings will really be there.
