sunroom heat loss ???

ScottMP

I have a customer who has a typical residential redwood add-on sunroom.

I would like to make it a seperate zone for her, but I want to check exsiting radiation.

I would like some opinions on the heat loss.

Sunroom is exposed on all three walls, is 12'x10' with a cieling that I averaged out to 8 feet, I took each wall and grouped all the windows as one window, three windows 9'x7',12'x6',6'x7'. Four skylights each 3'x7' ( basically thats the roof/cieling ).

Exsiting baseboard is 30 feet.

All windows are triple pane.

Floor is an overhang so there is nothing below. 10" of insulation.

Is that enough info ?

Hey Scott.

I did a quick manual J using my Wright Soft program. Came up with approximately 11,000 heat loss. Assuming copper residential baseboar at flow rate of only 1 gpm gives 560 btu per liear foot give almost 17000 btu's total. It seems like your customer should have plenty of capacity for the sun room. Hope this helps. WW

Thast what i was looking for. My heatloss said about the same. But I did'nt want to send her an estimate to switch to a seperate zone if the load was off.

Thanks for the help

We've done a bunch of sunrooms with Rinnai Direct Vent heaters. Easy install, sealed combustion, independent from heat system. For 11,000btu you need a model RHFE 263. LP or Nat'l.

The bigger problem

with glass sunroom is the overheating on sunny days. Some window shades would help overheating the space, and also saving the heat during the nightime would benefit.

Hate to see folks open skylights and dump that solar gain
