Floor Heating
Can Under floor heating systems be incorporated to existing concrete floored School buildings?
The existing concrete floor school buildingis 5000 Sq.m in area with 3 storey's, located in Scotland. The space heating of the building is being served with a boiler located at the basement. Can this existing boiler be used to supply under-floor heating? If yes, can the heat distribution be controlled, for example by users or sensors? How much floor thickness would the heating coils need? Is it going to be very costly or would it serve to be a good solution in the long run? Can the heat radiate
Who Yah:Underfloor heating does not heat a room to ceiling height - this is part of its benefit and means "no" to your point about transferring heat through a ceiling. It does not cause the currents that radiators do. It heats spaces to around two meters up from the floor in a very stable manner because ... More...
I have radiant floor heating. Without power, will my pipes freeze in the basement with no heat available?
My house was built 3 years ago with radiant floor heating in my basement which is living quarters. In the event of a power outage during a winter storm, my heating system would not run. What I need is ball park figure of the time that it would take to start freezing the water lines that are constructed within the cement slab floor. A brief outage obviously would be no problem. Lets say that at 10 F. the ice covered electric lines took 12 hours to get up and running. Probably, still cool. But at

Radiant floor heating.?
Can radiant floor heating be installed in the concrete pour, then after concrete has sufficiently cured (28 days) can a resinous coating, such as a epoxy/polyurethane floor coating be installed on a floor that will later be radiant heated. My concern is that these coatings are very moisture intolerant. Does radiant floor products, create any moisture in the slab that could rise to the surface. Does changes in temps affect the moisture levels in concrete. Electric radiant floor products s

Radiant in-floor heating?
We have a hydronic in-floor heating system in a slab subfloor that has an engineered wood floor glued on top without a seperating membrane in between. We like to change now to a tile floor. Trying to take the wood floor up we noticed this to be very piece meal like. That glue does not come off easy and I like to find out if anybody has any knowledge in this. Can I leave the wood floor in and install tile over it or do I lose too much heat? Any suggestions on how to remove the wood floor and glue
pipedreams:so the radiant heat is in the concrete slab correct? if yes then i would take up the wood flooring, alot of work but will be worth it. I would think you would have a big heat lost leaving the wood floor on, plus how thick the floor would be after putting tile on top of it. To get the glue off try he... More...

Under Sub-floor Heating Solutions needed?
I have a bungalow with a large irregular main floor area covered with about 400 square feet of 12x12 Porcelain tiles. The basement is unfinished with joists on 12" centers. We also have a Bradford & White Everhot tankless water heater (maybe possible to utilize for heating solution). I am looking for advice from experts in the industry to advise on a solution that will keep my floor tiles warm and not cost too much to maintain form an energy standpoint.
noskwik2:I'm sorry I cant help much but from what I've seen your best option would be the pex type tubing the is stapled to the underside of the floor from the basement. Then a layer of aluminum shielded insulation is stapled in between your joists to keep the heat going up. As far as the source of heat, I d... More...

Home heating question pellet furnace v. in floor heat!?
In our home remodel we are planning a change in the heating system. A home addition and several updates in the current house. Currently we are using a forced air propane furnace and its very expensive. We are considering in floor heat for the addition (master bedroom, bath, and family room), and a pellet furnace for the entire home. Has anyone any experience with both systems. How does price compare in operation AND comfort level.
ps we are in central IL!
sbleter:We had a radiant floor heating system in one of our previous homes, and we were absolutely delighted with it. However since it required an 80 gallon hot water tank it ate up the energy costs big time both in electricity to run the hot water tank and also natural gas costs. Your pellet stove, I'm alm...

What is the most efficient heating source for radiant floor heating?
I am replacing a twenty year old steam boiler and steam radiators to a radiant floor system. I am so confused by the number of choices to heat the water for this system. I could use a traditional boiler, a tankless hot water heater, or even a wall hung combination boiler and tankless hot water system. What is the most efficient system that will offer the lowest heating costs? I can use either oil or propane. Natural gas is not available in my area. My house is a 1100 sqft cape. Thanks for the he

How to control the temperature on under floor heating?
We are living in a rented apartment in Switzerland which has under floor heating, but there are no thermostats, and we are finding that we are far too warm during the night. There is a cupboard with a few horizontal pipes. Each has a tap...one for the bedroom, one for the lounge etc., but again no way of controlling the temperature as far as I can see. Can anyone help?
jayktee96:'Wet' underfloor heating is often regulated by a return loop at the manifold by means of a three way valve which simply keeps the same water circulating in the floor loop untill it cools a bit, then letting a bit more hot in to maintain the temperature, there could also be a flow thermostat on indiv...

candyman:yes you can do a staple up installation.

How can I cover an old grille type floor heating vent?

Which is a better heating system for a new home - Forced Air, Hot Water Baseboard, or In-floor Radiant?
Seem to me that Forced-Air is the worst for allergies. Hot water Baseboard is good but more expensive to install. And Radiant is the most expensive to install, and if there's a problem with it, you have to break open the foundation to fix it. Also we want to put real solid hardwood floors, and those are not compatible with In-Floor Radiant Heating.
I am leaning toward either Forced-air or Hot Water Baseboard.
Which is better?

Radiant Floor Heating. How do I get more heat?
Here's a diagram...

I get 160 degree water in the injection loop (1/2" cooper tubing loop on diagram). Maybe the 1/2" pipe is too small. Would 3/4" work, or defeat the purpose?
I can't seem to get no more than 80-85 degree water, supplying the zones. Any suggestions?

Radiant floor heating - what to do specifically before pouring concrete slab in basement?
What must be done right before pouring the concrete? Is it just about placing the pipes and tying them? What about the pressure test kit... Is it necessary and how do I set it up?
HVAC Man:Main things are making sure the pipes are places exaclty where they need to be, and also make sure they are tied down very good. You also may want to make sure you leave plenty of extra tube on the ends, its much easier to cut off a little extra rather than trying to splice it down by the floor.

Rich Z:Yes you can and you will save money on your heating bills. Make sure that it has an anticipator setting because the radiant heat tends to overheat at floor level while the wall thermostat (at eye level on the wall) is slower to sense the heat.
