mixing strategy

@ July 6, 2013 10:30 PM in mixing strategy

I hear what you guys are saying and they are very good ideas. My lower temp areas are Warmboard areas with wide plank,7" hard wood for a finish floor. I want the floor to be as stable as possible, constant circulation or as close as possible I think would be a good thing.
Thanks for your time any other thoughts are appreciated.

pex in Warmboard

@ July 6, 2013 1:35 PM in Best pex for warmboard

I have had problems in the past with keeping pex tubing (Uponor He-Pex) to stay down in the Warmboard groves. So have been using per-al-pex tubing which seems to hold better but not great especially on long straight runs. I have heard Warmboard has recently tighten up the grooves on their panels. And I am thinking of going back to using pex barrier tubing again does any one have any thoughts or experience with this.

Hey Swei and Rick,
Thanks a lot for your replies. Sounds like the Taco I series is the way to go. Rick, I am using a 15 degree Delta T that is why my flows are what they are. And yes I did do a heat loss.

Never installed a two temperature system before and trying to decided the best way to set one up. The project is a house with a mixture of tubing embedded in concrete slab and Warmboard. The low temp requires 9GPM, with a output of 63,000 BTU, using 100 degree water. The high temp requires 6.5 GPM, with a output of 45,000 BTU, using 120 degree water. The heat source is a Triangle Tube Solo, that will be set for the 120 degree water and thinking of using a three way mixing valve with outdoor reset for the low temp, either a Califfi NA164 or a ESBE 62.
I know their is a lot of options available and was hoping to get someones opinion on this.Thanks

Radiant heat back up

@ March 17, 2013 2:34 PM in Radiant heat back up

I live in central California, outside design temperature is 32 degrees, using a mod-con boiler suppling the heat for a in-floor radiant heating system (26,000btu on demand load) and a 80gal DHW indirect tank. The tank is a Boderus with two heat exchangers. One hx is for the boiler the other is for two 3x8 solar panels. I would like to supplement the radiant heating by use of stored solar water, but I am not sure what equipment and controls I would need and how cost efficient it would be. If any one has any suggestions they would be greatly appreciated.

Thanks Swei, Think I,ll stick with TT know then pretty good but your right about the tank think the 40 will do it thou.

small house combi

@ March 9, 2013 4:20 PM in Combi in small house

Thanks for your replies. The small house,little heat load, big domestic is the problem. Would be nice if their was a combi to fit the bill. So I am think of using the attic space putting in a Triangle Solo 60, which turns down to 16,000 btu with a 30 gal indirect for dhw. That way the indirect temp can be raised and tempered down for more output.

Combi in small house

@ March 9, 2013 4:47 AM in Combi in small house

I have a small house with in- floor radiant heat the load is 25,000btu and their is two small bathrooms one of them has a small soaking tub. I would like to use a Triangle Tube challenger combi boiler cc105. My question is, is this a good match for this system? If not could someone please make a suggestion.

Triangle Tube heat exchanger

@ April 8, 2011 6:02 PM in Triangle Tube heat exchanger

I hear that Triangle Tube is going to be changing their heat exchanger in the Prestige series this fall. Supposedly, they have a new and inproved one made with stainless and polypropylene. Has anyone else heard this and if so what do you think?

munchkin T-50 fan motor

@ November 5, 2010 6:38 PM in munchkin T-50 fan motor

I have to replace a fan motor in a Munchkin t50. I did it once before, but I think I did it the hard way could someone please tell me the easy way?

solar with central heating

@ May 25, 2010 5:41 PM in solar with central heating

I'm trying to figure out if the cost of a solar system to supplement a radiant system, in the mild climate on the coast of California, is worth the expense. I know it is done, but how efficient is it.

Roth panel installation

@ February 13, 2010 8:54 PM in Roth panel installation

Going to be installing Roth panel for the first time, and would like suggestions on securing to wood sub-floor. Roth says to use min. 8 screws per panel or glue. Which seems to be better. Also how about staples. (7/16*1 1/4 inches) 
Thanks Mike

I'am doing a above floor tube and plate system and plan on covering it with temper hardboard (peg board) has any one done that with success or see a problem with it? I would appreciate some advice.
