He mentions Uponor in the subject, so I think he means quick trak.

2 rooms I need help sizing

I am a heating contractor mostly Air heat But we are moving back to moms she is 80+ and could use some help .
We are remoding the upstairs one room never had any heat so I want to use warmboard and pex 1st room 153Sf 9731 btu heatloss will have pergo type floor. 2nd 210 SF 7703 btu loss .

best way to pipe ? home run to basement for each room ,how much warmboard Sf for btu loss? temp of water is it ok to mix with iron pipe and radators with mixing valve ? thanks

hot_rod

Sure

home runs would be a good way.

First check your loads. 9731 BTU/hr for a 153 square foot room seems awful high? Over 60 BTU/ sq. ft? Way beyond what that floor area could provide.

Remodel

Warmboard is a little tough to use for a remodel. Do you have access from below? If you do, Radiant Engineering's Thermofin might be an option. If not, a product like Viega's Climate Panel, Rehau's Raupanel, or Thermofin could be used above the floor also.

If you can centrally mount a manifold in a closet and make the piping easier, that would be my choice.

Btu sqft

I have to agree with HR on this. Btu per sqft way to high. Rmemeber when doing a radiant heat loss you cannot use a hydronic heat loss program unless you calculate the change in air exchange and design temp as we do not use the same numbers.

would two buderus or myson type panel rads...

entice you to bag that idea?

i have a feeling that these rooms must be uninsulated or "look outs" from an attic...even so, maybe more insulation is Key ingredient...just thinking out loud here *~/:)

i live a bit North of you and i would consider rebuilding the exterior wall if the heat loss was that high or at least getting an opinion from an isothene type (spray foam) insulator before proceeding much further...

Andrew,

Surely Dlux means Quik Trak and not actual "warmboard" dontcha think? Kevin

D lux_2

yes Quik Trak. I dont understand heatloss for radiant is different than scorch air ? going to have isoneen spelling ? sprayed in 2x6 rafters in room 1 room 2 has pink and blowin walls and 6 in or so rock wool overhead .
