Foam and aluminum radiant panels...

I finally found information about the styrofoam and aluminum panels that I saw a while back. There is a local supplier in my area that can supply the panels. They come in boxes that cover 96 square feet and the price of a box is $495 retail. I thought at the time that I saw them that is was a neat product but kind of on the expensive side. At anyrate the Beaverton, Oregon company that can supply the panels is located at the following web site:

http://www.spnwsupply.com/

This particular product is not listed on that web site however. I found out by talking with them that they can still supply the product and that it is made by Roth. The following web site describes the product and gives installation information:

radiant floor w/rv500 difficulties

Sometime, I'll get around to posting some pictures of this project we're working on...

We totally gutted our '69 Ambassador, reinsulated the trailer with the aluminum foil bubble insulation. (Which is really wonderful stuff. Sooo much better than fiberglass). We actually used two layers of it. One layer pressed against the skin of the trailer and ribs. Then as we attached our wall panels we used another layer by laying it on top of the ribs to provide a barrier between the walls and the ribs. We were a little worried about the insulation being too poofy and the rivits sinking in to cause a quilted look, but that really wasn't much of a concern once we tried it out.

We also installed radiant pex tubing on top of a foil/vinyl/foil sheet from the same company that makes the bubble wrap (we special ordered it from a local hardware store). We actually used 3/8" tubing and ripped 1/2" strips of wood to screw to the subfloor to use as channels for the tubing.

I have to interject and say that this came about because my dad suggested we put in a radiant floor. As a plumber/heating man he was convinced this would work, and we agreed. We're currently living with him, and he is helping us get it going.

So now we have our RV500 hooked up. We're using a closed loop system with antifreeze in it because I imagine we will be in some pretty cold places and we want the tubing in our floor to be protected. We could have a used and open system and just circulated our fresh water through it, but this just seemed like a better solution for us.

It did complicate things more because we needed a heat exchanger (stainless steel plate type-a small one) and another pump. We went with a couple of the smallest el sid pumps purchased from The Solar Biz (http://www.thesolar.biz/Our%20Comple...0Inventory.htm)
nice people. best price. they have a lot of cool things in stock esp. solar panels & batteries. We sent up our plumbing for the loops according to a diagram from the radiantcompany.com site. They have a diagram for a Takagi - another instantaneous heater so we figured it would work well for our system too. One nice thing about this method is that you can use domestic hot water while the radiant floor heat is on. Before we found this diagram we thought we would have to switch it back and forth.

We are having some problems at the moment because the RV500 is short cycling due to the hot water coming back to it. Dad just recently talked to Pricision Temp (The company that makes the RV 500) and he is in the process of obtaining info about how to modify the system to prevent this from happenning. One thing we will need to do is install a small storage tank for the hot water. I'll write back more when we've figured out a little more.

This has gotten pretty complicated and we are spending a lot of time & money tinkering with it. But if it works as well as we are hoping, it will have been worth it because my partner Andy & I plan on living in this Airstream for several years.

If anyone has any advice for this type of system, I'd love to hear it.

Hilary

nontoxic antifreeze

According to my dad, the plumber: The RV antifreeze is nontoxic - they put it in licorice - and they use it in dormant houses in the winter and then just flush it out with water in the spring.

I put a Pro-Com 28000 btu raidiant heater in my 86' and have had no problems other then uneven heating. Pro-Coms have a low O2 detector, I also installed a co2 detector. My avarge Propane consumtion for Montana living is 40 gallons/ month. That's running everything, fridge, cook stove and hot water heater. The best part about it is the price the unit cost me less then $200 with shipping. Oh by the way, no venting required. Our little forced air unit couldn't heat the 20 below weather of Montana we had to do something diffrent.

How about some updates?

Unfortunately I am still not quite at the point in my remodel where I can get serious about installing my radiant heating system.

In the meantime I would love to hear updates from any of the people who posted on this thread or any new readers about their experiences with hot water radiant heating systems for their Airstreams. How about it?

Where did you mount your Pro-Com heater in your MH? We'd love to install a vented propane fireplace in the MH behind the front passenger seat. We prefer to "camp" in cooler weather than hot but upgrading our furnace/heating system would be great also. a fireplace would add to the ambiance of "camping".

Floor Vented Heater

Does anyone know the name of the heater used to replace the Panel-Ray. The one that was in our '54 was gone but had an air intake hole in the floor beneath the radiant gas heater. This hole was screened and vented into the bottom of the heater itself;

I have started my radiant heating install...

Since this thread has surfaced again I thought I should mention that I have finally started installing my hot water radiant heating system. I have started a new thread to document the process. Check it out at the following link:
