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 Link to comment Share on other sites More sharing options...
Woodpecker Posted May 18, 2014 Report Share Posted May 18, 2014 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.

breezybass Posted May 18, 2014 Author Report Share Posted May 18, 2014 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 Link to comment Share on other sites More sharing options...
ted527 Posted May 18, 2014 Report Share Posted May 18, 2014 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? Link to comment Share on other sites More sharing options...

Electricity is sky high and going higher. See you on the big one. Link to comment Share on other sites More sharing options...

If that means losing the radiant so be it. See you on the big one. Link to comment Share on other sites More sharing options...
Woodpecker Posted May 22, 2014 Report Share Posted May 22, 2014 Quote:Originally Posted by Paul_M Electricity is sky high and going higher. 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.....

ted527 Posted May 22, 2014 Report Share Posted May 22, 2014 Queens ny 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.

mako20ft Posted May 24, 2014 Report Share Posted May 24, 2014 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... Link to comment Share on other sites More sharing options...
