Hello all

Iam in the process of building a 1800 sq ft house with radiant heat 2 bathroom.

I am trying to decied if i should use a tankless Navian combination boiler

or a burnham alpine condensing boiler with a indirect water heater

this will be place in a attic

what would you do / what would be best

You mention two bathrooms, but If you are comparing  hydronic systems you must be talking about radiant heat for the entire house , yes?



On the outside chance you are only talking about radiant for the bathrooms I would  go electric. 



For the whole house, more efficient typically means higher initial cost so crunching numbers may lead you to the most practical method for your needs and budget.

radiant heat for the whole house. i feel like i am gambling with the combination boiler. as far as quality,you hear conflicting reviews on these systems

they sound great in theory . but are they reliable and will they require more maintenance / service calls or last as long

will they provide enough hot water

Electricity is sky high and going higher.

See you on the big one.

My house i would go with a traditional condensing boiler with indirect tank.

 

If my house theres no way i would ever put a hydronic system in the attic, where are you located?

Get the simplest gas boiler you can get so anyone can understand, work on, and get parts for your equipment. If that means losing the radiant so be it.

See you on the big one.

Yes, I was suggesting that only if the bathrooms were getting radiant and the rest of the home was not radiant. Would be hard to justify the cost of a hydronic system to heat two 30 sf areas.....

The attic is supposed to be temp regulated with foam insulated air exchanger

 

IF the attic is sealed and foamed i might put a hydronic system up there. not a fan of water over finished sheetrock.

Water storage in an area above Sheetrock and/or living quarters....no, no and did I mention no? If you do elect this route please ensure you have not just a pan but rather a tub arrangement permanently affixed to a waste line.

 

If the situation were my decision. Simplest, quality brand name "standard" heating system AND THEN the addition of 220V electric, radiant for the 2 bath areas. Way cheaper initial investment and most of my customers honestly don't even notice a substantial bump in the monthly bills. Then again, with this being new construction and the extensive energy efficiency you're building into the home I can't see your monthly bill being much to begin with.

The wheels on my reels go round and round...round and round...round and round...
