Floor Heating
Can I relocate a floor heating return vent to the wall?
I want to relocate the heating return that is on the floor to the lower wall. It is just the return, not the actual vents that blow out the heat. It is right in the middle of the hallway and sticks up above the floor. It is hazardous and unattractive. Can this be done? Is it expensive to do? Thanks in advance.

What is the equivilent of floor heating in commercial aircraft.?
I know there are a lot of ex-military retired commercial pilots out there, or in here. Military aircraft had floor heating. What is the civilian counterpart to that function?
T1 Air can provide cooling or heating. Configuration of military aircraft is mission dependent. Floor heat in a military aircraft is an option dependent on that configuration. So do what is the civilian counter part.
I'm sure the old retired pilots will know since they would have made the transition.
Avrilfan:The modern engineering concepts in aircraft design, especially commercial, cater for over all comfort of the passengers. This area of design is so carefully tailored that the cabin remains at the most comfortable conditions for long relaxed journeys. It is much like the 'climate control' in automobi... More...

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...

If a house is already built, is it possible then to install radiant floor heating?
also what steps must be taken to install radiant floor heating?
wakaru8:It depends where you want to run the radiant floor and the type of floor it is. If its a concrete slab, then it'll be difficult and quite messy, but if you have access underneath the floor such as a basement under the 1st floor then its can be retrofitted easily.... 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

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
stedyedy:I installed my own radiant heating system. For the heating system I used a Munchkin Boiler, propane fired. I have been extremely pleased with its performance.

fireguy:are you thinking of electric heat or radiant hydronic(water) heat?

How can I cover an old grille type floor heating vent?
I just moved into a new apartment. It now has central air/heat, so the old floor heaters are obsolete. They are covered with a heavy duty black grille. They are large, maybe 3' x4'. It is completely open underneath. I can see gravel. However, the old heaters are still in place, so that leaves only a millimeter or two between the bottom side of the grille and the top of the old heater. Any ideas for covering this?

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...

My ground floor is solid. The kitchen and conservatory are to be wet under floor heating with tiles on top. Can I use the same heating system for my front room when I want to lay carpet. Electric underfloor seems to say yes but I can find no advice for a wet system.
Helping you:Yes you can. the carpet has a natural R value. This is what you should keep in mind when buying you carpet.

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?
finaldx:Properly installed, you should not have any kind of a problem with the Radiant Heating, and if you do , it should be under warranty.... More...
How do you check for leaks in a radiant floor heating system?
My gas bill has gone up and I can't figure out why, except that the heated water is going somewhere. We don't have a basement and I don't see or smell any sign of water.
Kurtis G:Drain the system, pressurise with air. (about 25psi.) If the system holds pressure for an hour or more, there's no leak. If there is a leak, you can usually find it from the hiss of escaping air. If not, a dye may be added to help locate the leak.... More...
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.

Installing under floor heating do I need 75mm seletex and if so where can I get this foil back insulation?
Its foil backed insulation sheeting on a roll. Also, have been told I need to add some flexible something to the screed to stop any cracking of the tiling afterwards. Does anyone know what it is called.
D A:The foil back insulation you describe sounds like Trilso Super 10 or Thinsulex, But are used for roof insulation. Sounds like you are running the underfloor heating from your central heating system. Lay 75mm Celotex / Kingspan insulation boards on to your concrete sub floor. Then lay pipe and floor ... 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...

Can I use any thermostat w/timer for radiant floor heating?
I just received my radiant flooring and it just came with a standard thermostat. I would like to have the option of having a timer on it, so I can program it to turn on and off when needed. Can I go out and buy any thermostat/timer for the flooring?
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.
There are usually two thermostats that are fu... More...
Which type of under-floor heating is the best, electric or water-fed?
Best being in terms of installation cost, running cost, reliability, and ability to heat a large 35 sq. m room. Will I need additonal radiators in the room as well?
xenon:There can only be one correct answer, and it has to be water-fed.
The water is heated by gas or oil preferably in a condensing boiler, and pumped around plastic pipes embedded in the concrete.

under floor heating or normal radiators?
I hope to build a new house on the side of my end terrace. I dont like radiators so wondered if underfloor heating was as good as or better than normal radiators. I will not have blown air heating.

Radiant Floor Heating. How do I get more heat?
Here's a diagram...
http://home.comcast.net/~kierchar/radflr.jpg
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?

How can I put a central heating duct into the bathroom floor without pulling up all the tiles?
Our house has a gas ducted heating system that a previous owner installed. There isn't a duct in the bathroom, but we noticed one under the house sitting there ready for it. Is there a way I can put that into the tiled floor of the bathroom? The main problem is doing it without having to retile the bathroom - can I cut existing tiles without pulling the whole lot up?.
Alternatively, who do I need to pay to do this for me? A builder? A tiler?

When using in-floor heating w/Glycol, does one need a furnace for the upper floors, or should the heat carry?
roadlessgraveled:It's going to be hard to make the lower floors hot enough to carry to the upper floors.

Usually there... More...
i have a question about in floor heating?

candyman:yes you can do a staple up installation. They make special heat panels that the tubing runs in and helps reflect the heat up.You then insulate after them to help even more.You will also have to install a mixing valve on the system to drop the water for the floor down to the right temp. This install... More...

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.

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 need to replace a floor-standing boiler(heating only)is there a suitable condensing boiler for an old system
to re-position any replacement to the current 'Diplomat' cast iron model would be very awkward and with an open vented gravity system could I possibly get exemption from John Prescotts 'SEDBUK A/B' ruling by fitting the most efficient alternative (as a condensing boiler might not run at top efficiency anyway without significant modifications all round)
Why is there no reference from boiler manufacturers to SEDBUK B grade. I think wet Central Heating is getting too complex and I may consider
opie with an attitude:You could replace your controls if the boiler is in sound shape (the boiler I work on is 30 years old and the piping is over 90 years old) If you have radiators I would replace the steam traps on each radiator if you haven't done so in the last 5 years. These traps are located on the outlet side a... More...
