Hello everyone . Just a few questions regarding radiant heat

Ratt

Hello everyone, I've been doing some research on this site on radiant heat . There is so much info!! I have a peerless purefire boiler with forced hot air that I would like to convert to radiant heat. Should I go with ultra fin system or aluminum heat transfer plates? I have heard that the ultra fin system is a bad Idea for high efficiency boilers , can this be verified? My house is 2100 square feet one level.

The heavy duty extruded aluminum plates will give a higher output than the Ultra-fin. We use 3/8" barrier Pex, rather than 1/2"...it's easier to pull, keeping all loop lengths under 200'. The boiler will need a mixing device, either manual or 3 way motorized valve and control. Your efficiency will depend on floor coverings, and where the home is located (design temp)

If you do a heat loss using Uponor's ADS software (or equivalent), it will tell you the loop lengths and produce manifold balancing charts. Uponor has a good instruction booklet on how to install a staple-up application with plates using QuickTrak. The heat loss will also tell you if the rooms will be underheated, even with RFH.

Guessing can be very problematic and result in poor performance of the system.

Ultra Fin

Yes Ultra Fin is a bad idea on a condensing boiler. It requires a constant 180 degree water temp to work effectively and that would require your PureFire to never provide you with what you paid for, a condensing boiler.



Need a good radiant heat loss and design program as Paul has pointed out. Go with the Uponor 3/8" Joist Trak.

another option

if you want to economize and don't mind looking at a few radiators is a plateless radiant system with panel radiator supplemental.



the supplemental is usually small, and you can get conditioned floors and low temperatures more economically than with extruded plate systems. but, there is aesthetic issues and furniture placement issues to consider.

my home is located in new york. Im sure the radiant system will be much more efficient than the forced hot air system that I have now. I work in the water treatment business along with alot of heating contractors so im going to be doing a lot of the work on my own like I did with the forced hot air.
