Anti=freeze

Wayco Wayne_2

Don't wanna but... I have constant circulation because of the air under the sun room, its 8 feet in the air on columns, and I just imagined a power outage on a cold night. It would cool off more quickly than the rest of the house. I could tell the Home owners to put a kerosene heater in the room in that eventuality but I would rather things be idiot proof. The last radiant floor customer I put glycol in didn't return my calls when I tried to tell them to check the acidity of the glycol after 2 years. Didn't want to be bothered with the maintenance I guess. What to do, what to do. WW

Installing

a radiant floor on a sunroom that has nothing under it but air. It has joist trak plates with pex tubing. I look at it and imagine a power outage in Winter and wonder if I should put in anti freeze to pevent damage in that situation. If I do it will take a bit because the heat source is a 30 gallon gas water heater isolated to heat just the floor. first question...Should I or shouldn't I. 2nd question. If so what kind of anti freeze? 3rd. Where do I buy it? RE michels sells some but it's already mixxed and kinda expensive. Thanks for any input. WW

Wayne....

I realy don't like glycol...more work than its worth. It decrease floor output and is a maintenance headache. Cryotec by Hecules is the std. here...$60.00 for 5 gal....

There is rule that always holds true.

"If it is able to freeze, and if it is in a place where it can freeze, then some day it will freeze"

We may be dead men when it happens, but then again it may happen this winter.

I would put in the antifreeze. Not cheap but a lot better than the alternative.

Be sure to read the instructions on the container so you have the proper mix for you climate.

WW i think you have the right idea...

get yourself a taco X block isolate the floor from the rest of the system, put a by byass loop and no kinks on both sides of it,then should a mishap occur it could be drained down...friction fit and foam should make the floor box beams and rim joyst able to slow the loss of heat to a dull roar...a single line run around the perimeter would also give you "options" in the future for thawing purposes . just make sure the insulation is real tight ,no daylight ....i hate this stuff buh Tremco has its place in that part of the envelope ..homeowner insulation installs miss real important points...i know that even when you show someone something and they are doing it right the min you turn to your work they are right back at it again...

Wayne,

If a power failure happens, what's the average time it's down?

I would consider a system based on constant circulation and one of the battery computer back-up packs. They'll run a single circulator for quite a while during an outage, as long as it isn't cycling off and on. Just a thought. Chris
