Is Tankless a waste o' money?

Mr Homeowner asks..._2

I am planning hydronics into the remodel of my home, and wonder if I should consider using a tankless wall hung unit with an indirect DHW, instead of the traditional floor mount boiler.

Tankless is relatively new here in the USA and I wonder if this stuff is worthwhile, or a bad investment?

Not a waste of $ but...

If you can use a wall mounted boiler...do. Peerless Pinnacle has a wall mounted 90+ that vents with PVC but to run an indirect also you are going to need more BTU's. A Pinnacle/Munchkin can easily do it. Possibly use a wall mounted boiler for heat and a tankless for Hot water.

If you are going to use a tankless for the job due to costs up front, I would use one for Heat and another one for domestic hot water.

Without more details on your system, it's hard to get much more specific. Personally, I'm all for tankless, but am going to use a boiler for hydronics whenever I can. That's what they are made for.

I agree

use a boiler and indirect. WW

and a tankless heater for heating only

must be certified for that application.

PM magazine had a real good article a few months ago about making a water heater work as a heating system engine. By the time you have the beast safely controlled you will have spent more money on an improvised heating system than you would have had you allowed a boiler manufacturer to fund the experimentation and certification process.

I like trinity boilers and rinnai contiuums. Both wall hung both tankless and both very efficient. I love the on demand systems.
