Nice Idea...

Greg Gibbs

Jeffery Cambell w/ Simply Solar (Steamboat Springs, Co) hauled me to one of his jobs last week...I thought I was going to see another great Boiler installation...He could not wait to show me his new "Under Constrution" Boiler...
Jeffrey like so many others is sick of construction dust and other trades damaging his Boilers.
I thought this was a pretty slick idea

Firing Boilers in \"under construction\" conditions.

Jeffery Cambell w/ Simply Radiant (Steamboat Springs, Co) hauled me to one of his jobs last week...I thought I was going to see another great Boiler installation...He could not wait to show me his new "Under Constrution" Boiler...
Jeffrey like so many others was sick of construction dust and other trades damaging his Boiler installs...
I thought this was a pretty slick idea...He now has two electric water heaters he takes from job to job one is 14KW
and the other is about 28KW ...He uses a simple 24 hr timer to to start a circulator. This job was warmfloor and the timer ran from 7:00 A.M. to 5:00 P.M., on a slab install you could run the "boiler" @ night and reap the warmth of the solar mass all day... You have to remember this is in Steamboat, it is cold all winter.

120 volt T-Stat

He can also use a 120 v. T-stat in line w/ the power to the circulator to control temp. -Greg

Insulation

Once they insulate I will use a line voltage tstat but with out insulation there is no reason to heat the shell at night. It works great during the day for the subs though. I am supplying the system with 110 degree temp.using Warmboard radiant sub flooring system. Even without insulation with outside temps in the teens and low 20's I able to keep the inside around 55 degrees. Its great because unlike traditional temp heat sources the heat is staying down were we are working and not going out the roof. They will be insulating later this week and I can't wait for the building to actually hold the heat.
Try it for yourself it works! Jeffrey

Warmboard

Have you used this much? We're considering it for a project.

How does the tubing hold up with the other trades working on it?

Any problem with sawdust, wood chips etc after the tubing is in place and before the finished floor is installed?

Warmboard

This is my second project. The first went alittle rough but the second went smooth. The first was rough because the contractor did not listen to the warmboard rep. We were suppose to cover the floor with 1/4" masonite board immediately after the tubing install but instead he waited a month why I do not know. Needlessly to say, the tubing was hit 8 times. Not too big of deal. The second project only one hit, its really easy to fix when its exposed. You need to cover the tubing for a couple of reasons one is UV rays can ruin the pipe and tow it protects from damage. I would recomend building the entire frame including roof, excluding the interior wall. THen install the tubing and finish the interior walls. If you are considering theproduct talk to your local rep. They have a list of acceptible tubing. I used Wirsbo. They will also give you great support and a blue print map to follow.Finally it was very easy to clean witha shop vac. I have used othe r aluminum products and they all seem to work great-higher output with lower temps=higher efficiency. The aluminum tranfers the heat much faster than Gyp or concrete. Good Luck Jeffrey

Yeh,GC's get a little stressed when.................

We start telling them when this, that or the other thing can happen. We just moved off a 1,500 sq ft Climate Panel job today. The GC had a real "deer in the headlights" look on his face when I told him the CP wouldn't be installed until after the drywall crew had come and gone. Then he flipped when I told him that after they had gone, we needed a week to get our tubing run in the basement ceiling before they could come back and drywall the basement. He wanted heat in the building RIGHT NOW!. Which brings me to the origonal subject. Jobsite temporary heat.

We keep a couple of cheap 80% furnaces around for that application. Cheapest pieces of junk you an buy, you can guess the brand. We'll run a hunk of copper tube to it, vent it out a window that we seal off with metal, hang a stat right on the furnace and let it rip. If you're thoughtful about location of the furnace in the house, it'll do a pretty fair job of heating a place fairly even. The furnaces survive about 2 seasons and we scrap 'em when they get to gunked up to be safe. All in all, it averages out to be pretty reasonable on a per job basis.
