Client might sue

Have a clinet who built a spec home in Aspen Colorado. Sold it to a rich lady from Arizona.

Last year and now this year, she has complained about 1 room which cant warm up to her satisfaction.

Long story short, would like some tips on what to look for.

The entire house ( approximetly 6000 sf skinny slab except for lower level, 4 inch slab) is radiant heat with supplenental schorched air. All other rooms work. The room that does not work is a bed room,carpet, 2 out side walls, big slideing glass door, no curtanis. She has a problem because she has thermostat set for 74 degreees, but the thermostat tells her the room is only 64 degrees.

50% of the room is bed, furniture etc. There is a bath room on same zone, floor is always quite warm.

Any thoughts on what to look for, very much appreceitated.

I'd like to put a thermometer in room to see what it reads, maybe TT bad, please recomend the best way to do this.

I also know that the insulation below and above is correct. this room in bottom floor, Slab, I was told that insulation was used below radiant. Insulation above is correct, radiant above, house is 3 levels.

This lady is rich, very nice to look at, every thing in the house works except this room. The developer has had couple other heat guys look at problem, no body had any good Ideas.

I hate to raise the supply temp out to floor for only one room.

If I check supply temp across supply and return, and it is more than 20 degrees, whats the solution?

If I caN SOLVE problem, developer will give me millions of dollars of future work!!!!!

Yeah right,

Thanks for the help in advance. Todd

well, you are comming from behind the 8 ball on that one.

heres why you didnt install the loops ...so how long are they? and in relationship to what .? i'd shut down other zones in the vicinity for a day say make them 60 F see if that room indeed is controlling the zone's heating ...it... maybe it isnt! Oh Joy! say it is..well what temp is the floor yesterday and what is the floor temp today...what is the outside temp yesterday when you determined the 64 degree room/floor temp? is the zones in comming water temps around 120? the out going temp is it within 4,10,20,30 degrees of out going supply water? maybe the tubing was different loop length and is unbalanced no problem, balance the flow to the longest length...maybe its all it can do...if it is hooked straight into 180 degree supply side headder we will all get back with you

Need more pump...

if you've got a 30 degree delta T, you need more flow. Check to make sure that any (if anyy) pressure activated bypasses are properly adjusted. If not, go to the next bigger pump. Trying to reverse engineer one of these puppies is a mean female dog...

As for monotoring, as long as your client is willing to put up some buckage for monitoring, go to www.onset.com and check out their 4 station Hobo. I have one and love it. You could watch system supply and return, floor temp and room temp. You may have to reduce the R value of the carpet too.

A million dollars eh...

Carpet, pumps and restrictions - oh my!

Same thoughts popped up here too. I'd begin at the beginning and do a thorough heat loss calc to see what temp you actually need to send into that zone's circuits. That should also reveal if the carpeting was added (yeah, like that never happens!) after the job was completed or without telling the installer during the design phase.

Carpet

two outside walls, Big glass, furniture, ouch! I'd like to see what the original design called for regarding supply temperatures, and expected output compared to required.

Check the floor surface temperature, if you are not getting 80 or so, you may not meet the load on the cold days.

Hot rod... you just make and sell to Todd another one of your custom hydronic bedframes and then he can save the developer and everyone will be happy!!!


BTW, a small set of curved needlenose pliers popped that little white ring out like magic.

Radiant design

I would shoot for an average temp across the floor of 85 degrees. The delta T should be about 15. Have done many carpeted areas. The carpet and pad must not have a heat resistant barrier which some do.

can you

tell if that room is the last one in that zone? if so...Can you reverse the flow so that it is first? This would give higher supply temps to what is probably the highest heat demand room in the loop.

my $0.02 in addition to the other great minds here.

I dont remember if this was mentioned yet but the material for the carpet and pad are very important.

You should check out the RPAs flooring guide if you already havent http://www.radiantpanelassociation.org/i4a/pages/index.cfm?pageid=246

so, all of us are saying.....

what is the heat loss for the room? what are the loops temp supply and return,how do you know if there is flow? how much added insulation is Built up over the slab?and if all this info is suspect what about a new pannel or two ,ceiling ,wall panel, or go creative and make a fancy railing or heated bench+panel something neavou:)

Kidding!!!!!!!

Come on, I wasn't the only one who thought of it.
