Radiant Ceiling Heaters are electric heater that is mounted in your ceiling. If I can't go all the way up with the bookcases, then how much room must I leave between their tops and the ceiling? Otherwise we keep it on 55 degrees to keep the house from getting too cold when we are at work. energy consumption (Zmeureanu et al., 1988; Howell and Suryanarayana, 1990; Imanari et al., 1999; Petras and Kalus, 2000; Miriel et al., 2002; Feng et al., 2006) and (3) favorable tie-in DIMENSIONS | 24 x 24" and 24 x 48". Our home is just under 1100 sq feet with 3 zones. Here's a brief study of assessing clains of lower thermostat settings in hones with radiant floor heat done by CMHC http://www.cmhc-schl.gc.ca/publications/en/rh-pr/tech/01-106-e.html, They found slightly higher settings in the radiant heat homes and concluded: I will have a professional come and do the work and getback to the discussion with the results. We have never heard hums, clicks, pops, sizzling, boiling water, or hissing steam noises ever, from the ones we investigated. Robert, You are using an out of date browser. I read about it, and anticipated that we d be comfortable with lower temp, The very first radiant heating systems emerged in the Roman Empire. But how does it affect energy consumption ?? Perhaps better than a carpeted radiant floor hot rod It is not that simple minded. From above heating feels very,good on a cold terrace though, The floor keeps in between 21c and 27c Your claim that "A BTU is a BTU" is certainly true, but you said that in response to a point made that a "BTU is not equal to a KWh". Periodic Inspection Reporting & Certification. The ceiling had to be replaced and it originally had a cement board on it. I hope more people return and share information. I have never seen it installed between two layers of drywall before tho. The answer, Warmboard found, was to combine hydronic tubing with lightweight, highly conductive aluminum. Navies on demand Hot Water . I beg to differ, Robert. Kingston - 12 miles.Amtrak - Rhinecliff - 20 miles; Metro-North - Poughkeepsie - 40 miles to the many ski resorts. I had the floor boards up today and noticed that the ceiling rose for the room below, was wired with 3 singles. Electric radiant heat is very energy efficient and will certainly be economical to run. This is not a high heating bill for Minneapolis. The entire house is radiant heat in the ceiling, except the small kitchen which was an addition and has baseboard heating. You act as if people are concocting magic when they discuss radiant heat but standing in the sun on a cold day should provide ample evidence that radiant heat is fundamentally different from heating the air, and the fact is this method of heat transfer to the human body is fairly efficient. It is one of the most efficient ways to heat your home and could possibly save you as much as twenty percent on your energy costs. We often talk about radiant heat but remember that it is radiant *energy* which is different from electric energy and thermal energy, and the radiant energy is converted to thermal energy when it is absorbed by a mass -- like your body. Here's an excerpt from a paper I have (which references many other studies). First of all, your lectures about mean radiant temperatures and comfort are condescending. Still using the ceiling electric as main source of heat. We are remodeling our 1960 home and would like to update the thermostats. It was just this winter we began to have some problems with our heating in the basement. Of course this statement is nonsense, but then, your prejudice against radiant heating, of any kind, should be obvious to the most casual reader of this otherwise accurate and useful site. It uses a Switch Action Open thermostat. -Patrick Beebe-Sweet, MBA in Green Construction. how do I know for sure I have a reading on a ceiling joist and wont be putting a heavy ceiling screw in the heating system?? Thank you. Our house was built in 1985 and we had friends who had one about 1975 with the same heat, they loved it too! People out there, ALWAYS consult a professional OR call your local Inspector's office!! http://www.toolbase.org/PDF/CaseStudies/enerjoy_case_study.pdf. All rooms used or a few not? Below is the link to the guidelines. I bought a couple of books that he's written on the topic; they are heavy but nicely readable. And it is just perfect here "This type of heating has the same advantages of other forms of electric resistance heat, including electric resistance baseboard, electric mats under your tile floor, and electric resistance space heaters. 1- i agree that hydronic is the best of both world, except in its isntallation complexity and potential problems/maintenance that is why i personally chosed electrical, but again worst heating ever and super inefficient. It is a film type heat and my installers said it was easy to do. Seven years or so ago we had a remodel done and our kitchen and bath wires were inadvertently cut. Just after we bought the house, a friend wired in a light/fan fixture, so I started there and removed the fixture and base. one room is no longer working however. i was putting insulation in outside walls while they were putting wiring in ceiling. Last year (2022) we filled Jan, Mar, May & Sept and we live on the Massachusetts coast. Myth No.2: Radiant Ceiling Heat is Not Efficient. Ducted-air systems (I prefer that to 'forced-air', which implies excessive pressure and velocity) need not have a wind-chill effect. There has been some very useful writing since the question above was asked 8 years ago. A well insulated room that utilizes radiant heating systems can save money over a gas system if used and designed properly. It's very comfortable and maintenance-free. The main hall, where the seating areas are, is heated via forced air. Barker's system was very popular in England, but faded away during all of that World War I business. It would be great if John writes a blog post to generate a good discussion here. Sorry for drifting off on a tangent Just noticed this discussion. Of course, Wright was ahead of his time in more ways than one, so it was not until decades after his death that radiant heat finally came into focus. Different systems have differing system-efficiencies- with differing fractions of distribution loss. However I'd be happy to go into greater detail at another time, perhaps in another topic area that is more appropriate. If it leaves a client without power Hi everyone, Tag: Radiant Ceiling Heat 1970s Electric Cable Ceiling Heat Pros and Cons Many houses built during the 1960s and 1970s, in areas not served by natural gas suppliers, incorporated electric cable ceiling heat as the primary means of keeping the interiors warm during the cold months of the year. 1990). Good luck to everyone and stay warm!! I also suggest you get in touch with John Siegenthaler who is a guru in this area and he can walk you through all of the technical considerations. "Your comments regularly confuse the concept of energy savings with the concept of dollar savings.". Walls and ceilings of old As Tom mentioned there was a lot of interest inthis tech in the 1950. look at some of the big names that were involved. This principle of using wire elements to create radiant heat has been greatly refined over the years and forms the basis of many current energy-efficient infrared heaters made today. The entire unit is mounted in silicone rubber to eliminate hum and expansion noise. But you cannot compare forced air gas heat with electric radiant based on the cost of electricity and gas alone. While Warmboard offers better-than-average . This is a good alternative to houses with central heating system. A quote from the study you linked to: "Because a portion of the energy savings with the Enerjoy system was related to room by room setback and the specific number and routines of the research home occupants, savings for other households may be different than those obtained in this study. How can I find local installers of it.? Thus convective heating systems typically respond slower especially to step (temperature) We had them come to a job 6 months ago to repair 1 cut wire after a homeowner tried to cut-in his own cans. That said, many wonder why radiant heating isnt in more American homes, especially considering its popularity abroad (in Europe and Asia, 40 and 80 percent of homes, respectively, are heated by a radiant system). A few weeks ago they were working fine. This year we decided to try to bear it and have set it at 61. Btw Martin, fuels costs are way to high here to consider anything else than fire or electricity, The tech wanted the sheetrock/plaster removed in a 2' radius around the break, and the repair to the wire cost around $ 850.00. It is also greener, as less energy is wasted in this process. It will not keep a consistent temperature. We have electric radiant heat in our ceilings in a ranch house built in the late 1960s by my uncle. When applied to the sizing of a radiant system, conventional heat-loss analysis often includes a reduction in design temperature from 70F to 65F and a 10% to 25% reduction in building air infiltration, exfiltration, stratification and glass heat loss. The heating working great, I just want a digital thermostat put in. every room of the house has radiant heating and yes it does dry out the joints and will crack it over and over as heat will remove moisture. Alas, I've gone beyond the point of answering the Original Poster's question, and I don't wish to derail his thread. Here in heat-pump country we learned a long time ago that low-velocity high-volume systems are the way to go, and they make for a great, easy to manage background system. 1989). Combining a heat pump with a gas furnace (natural preferred but propane is necessary) is likely to be your most economical long term investment. Typically radiant ceilings in cooling absorb heat for 60-70% by radiation and the remaining (30-40%) by natural convection. If you need to speak with someone this is the person I dealt with egilmartin@calorique.com phone is 646 369 2527. Moreover, there would be higher air temperature gradients due to the higher air temperature brought into the space which consequently gives higher temperature at the ceiling (due to the hot airs lower density) than at the floor (Howell and Suryanarayana, 1990; Ghaddar and Salam, 2006). In the older form, electric heating elements are sandwiched between a layer of drywall and a layer of plaster. You received a plan on which sheets went where. Kevin, still here and reading all with interest. If you use an electrician, let him know you've done the research so you don't get screwed on the replacement switch. Regular paint? Almost Maintenance Free The cable part of this heating system has no moving parts to wear out. We are very happy with the radiant system. In an era when energy costs were not so prohibitively high, it might have been fine to install an all-or-nothing system, one that offered no compromise between the off setting and full-throttle operation. My condo was built in the 80's and apparently radiant ceiling heat was all the rage. But even a gas-burning 50%-er would not make electric radiant mats a more cost-effective solution in most markets. Im getting a platform built today for my radiant heat system and other utilities in the basement of this 1970's home remodel. . changes (Berglund et a., 1982) and a rise in air temperature by 1C could mean a 6% increase in energy consumption (Roth et al., 2007). There is a 3-wire cable for each room that runs 2 hot wires and an unshielded ground from the breaker box to each room for 220v. ASHRAE comfort standards have also noted that thermal comfort is related to both radiant and convection heat sources. (typical houses in those days were all 1/2" regular walls and ceilings) It was a really clean even radiant heat. Only when the boiler and distribution plumbing are in uninsulated unconditioned space does that loss add up to much. In general, these studies proved that radiant heating systems offer the potential of (1) reduced heating unit sizes (due to reduced heat load and peak load), (2) reduced In the attic, there is a vertical 2x4 (extending up approx. A hot-water baseboard or radiator system, in comparison, runs with a water temperature of 160-210 degrees. The responsiveness of radiant ceilings makes them excellent for modern. In the end, you can save serious money on home heating by choosing any radiant system, but among all manufacturers offering radiant products, Warmboard can save you the most. 4.5 4.5 out of 5 stars (699) $879.00 $ 879. "B. Radiant heaters vs. convective heaters They may be good for retrofit. Steve, In the next phase of development, radiant heating took a big step toward becoming its own entity, an active system capable of providing heat with or without help from the sun. Most parts of the country are paying about $1 a therm for natural gas. It's an older system and I'll describe what I learned about it. Any help with this question would be much appreciated. Radiant ceiling heat: This system heats the room from the top to the bottom. About as much use as a bad bellyache seemed to be the concensus amongst users,now long since converted to wet systems.If I recall it was fed on the onpeak side of E7 via a T/S and contactor,and available 24hrs. means that radiant heating systems increase the mean radiant temperature (MRT; average room surface temperature) to which occupants are exposed, thereby allowing comfort at lower My insurance company wants to know who the manufacturer was, how can I find out, and who can I get to inspect it for safety???? We have radiant heat in our ceiings. However, there was no voltage on the other grid lead. Ill post when i talk with electrician. It should cost less than $100. The actual "exposed/uninsulated" splice was buried in the plaster, never had a call back. They had full heat sheets, half heat sheets, and 1/3 heat sheets. Radiant ceiling heat is a style of heating that is significantly different from the radiators or forced air ducts that you may be used to. I have no idea what sort of ceiling heat is being discussed, but when I lived in Colorado in the mid-70s, I worked for a contractor during the winter building expensive custom houses. I have the same issue and I dont know what it is but my electric bills are through the roof. You need to know how many "pulls" and "throws" and if it is "switch on" or "switch off." Morgan : The human body is a radiator and it is also a detector of radiant heat. I'm really not trying to start a Riversong battle -- just trying to shed some light where you are misinformed. Do I need to do anything with the wire if I do clip it, beside insulating the end? Bedrooms are so comfortable at times it is not even necessary to turn on heat in those rooms unless temperatures become extremely frigid. In one of our more recent design/build radiant systems we radiated the slab in the basement and the ceiling for the main floor at the same design water temperature - 110F ,which of course modulates with outdoor air temperatures having an average design water temperature made for heat pump or condensing boiler. It's the type with a wire snaked back & forth, embedded between two layers of sheetrock or plaster. Since we have already exceeded building code and comfort expectations with a well insulated house and argon filled thermal pane windows, everything added subtracts from ROI and diminishing returns are the only guarantee. But at the end, i will still install heatpump mini splits to cool, so with the effeciency difference, they will see alot of use in the off winter months heating period. Many interesting posts enjoying the debate. I understand where you're coming from - it's a very common belief that you can equate a therm with the equivalent kilowatt and just multiply the costs to get a comparative answer, the truth is you simply can't. Mine is wire embedded in the drywall, NOT between two layers. Panels, each inset with hot-water tubing, lie under the floor material of your choice, delivering heat to the space above quietly, invisibly, and in a constant, enveloping way. But for homeowners who want warmth more than anything else, the reason to choose a radiant system is that its design and technology always ensure maximum comfort. Here, the heat responds to thermostat adjustments, not gradually, but more or less instantly. There is usually a 3" wide by 8" long drywall repair that needs to be made. Sounds like you are doing well with your set up. 2. I am sorry this feels condescending to you, but the way you put down anyone who tries to explain radiant heat to you comes off as condescending and uninformed. Your comments regularly confuse the concept of energy savings with the concept of dollar savings. Your $500 would be impossible for me at 16 cents a KWH and I have just under 2000 sqft. Fix cracks and skim coat entire ceiling. Radiant heating systems operate with water temperatures of 90-140 degrees. Thats one of the reasons that more and more homeowners are switching to radiant. Voltage from each hot wire to one of the grid leads showed 85v, same as my good room. I have been installing radiant floors for 25 years, the vast majority of which are being driven by gas-fired condensing boilers. You posted a similar comment on this page on Feb. 9, 2012. Give us a call at 562-595-1448 to find out . Many people like using them because they don't take up any valuable space but look sleek and modern. ". http://oikos.com/esb/37/radiant.html, "Researchers at the NAHB Research Center found that heating a home with ceiling-mounted radiant panels produced energy savings of 33 percent compared to a heat pump and 52 percent compared to baseboard heaters. It's NOT a heatlamp! Also We need to repair one wire that the electrician cut into. of well insulated living space last month (December) for less than $100.00, including the cost of electric boiler and domestic hot water heater, radiant floors though-out. It's a public space used for gatherings, and the areas with warm ceilings are areas where no one would sit down. On the other hand, a convective heating system produces an environment where the air temperature is greater than the MRT in space. When we replaced the furnace, we added digital thermostats with no issues in all 3 zones. And its only a matter of time before winter returns. I live in central Ohio and live in a home that was built in 1974 and has radiant ceiling heat. One of the styrofoam tiles fell out and it apears that the popcorn ceiling is covering the heating elements. Google the old one. http://www.radiantec.com/why/technical-explanation.php, Partial quote: In this particular installation, warm ceilings probably work great. The house was built in 1954 and we had the original furnace replaced 2 years ago. Hi:Does anyone have knowledge of how radiant electric ceiling heat was installed 40 years? All answers were no and i wouldn't hold him responsible if anything happened. Floor and ceiling heat and love it. I believe the floor and ceiling heat is Perfectly warm and their deicing is Perfectly clear. Improvements to chimney flues occupied many scientific minds. I sent them both a website inquiry. But I also know that both use electric resistance heating elements. Fires around the building fed heat into these hypocausts, which in turn heated the interior spaces of the home. If you're going to work on your system, be careful, you're playing with 220v.
