![]() which helps to make a place feel comfortable. Sand, concrete etc all offer a "thermal mass". they didn't have PVC pipe or boilers or such but they ran heated water through channels under the floor. Yes, that is essentially radiant in-floor heat. find someone who KNOWS the stuff to work out your design. Īnyway I see nothing BUT inherent compatibility between radiant heat and a properly designed / installed geothermal system. Installation is usually quite steep compared to other systems. Geothermal is very basic principles as well in a PROPERLY designed system the cost of operating can be very low. Radiant heat is incredibly simple technology though some "versions" put in all sorts of doo-dads to make it seem more impressive. I have no idea what "out of balance" means other than the guy hasn't done one / isn't very familiar with them. ![]() If the g-heat pump can supply sufficient hot water to provide your heating needs then it is indeed ideal for radiant. it could be a wood burning stove, a conventional water heater by propane, NG, or electric or solar or whatever. Radiant heat doesn't care where it's hot water comes from. Geothermal is simply a way of obtaining heat other than by burning fuel or an electric heating element. I used real hardwood flooring installed completely normally EXCEPT installed directly upon the subfloor. Been here 5 years now with nothing BUT radiant heat. I've got nothing but hardwoods maple and white oak. Radiant in-floor heat and hardwood floors play JUST fine together. No such issues with radiant heat.ĭon't know if I've answered your questions or not. You need hotter air for it to "feel" warm if it's moving. A warm mass of moving air can feel cool especially in winter when humidity levels tend to drop. we are all accustomed to forced air being quite hot. Again radiant and hardwood floors are inherently very dust free.ĭon't know enough about geothermal to say if it's capable of generating hot enough liquid to do forced air via a heat exchanger. Also consider that any type of carpeting is going to contribute at least some amount of fibers etc. this may well be a source of much of the dust etc. In an older, less tight house you are sucking air in through all kinds of little leaks all over the place. A tight house will tend to be "cleaner" as the only outside air coming in will be THROUGH the ERV / HRV which are filtered. If you're doing new construction don't forget an ERV or HRV in a tight house you HAVE to have it. and if DIY installation of it is within your abilities ( time more than anything ) it's tough to beat in the overall picture. There are some places out there that charge absolutely outrageous amounts for radiant heat and installation. It also depends upon having a good, properly done design by someone who knows what they're doing. Geothermal is cheap to run initial installation is more but that depends upon what type. If you have to have A/C don't know any way around ducts etc. įorced air blows whatever is in the house around. I can answer further specific questions about radiant heat if you're interested. But, it indeed is quite efficient and without question exceptionally comfortable and clean. GEOTHERMAL FOR RADIANT FLOOR HEATING COST INSTALLI did my own radiant heat install it was NOT the cheapest way to go. Many times spending more up front will give long term benefits in more ways than financial. While cost is a factor to all will you be uncomfortable with results of the cheapest system and derive comfort from the fact that it was cheap ? I think not. ![]() A cheap forced air furnace would likely be the cheapest to install, or electric baseboard. " Most important, which is the most economical at installation? " Don't think this should be the major factor at all. it will do a poor job of dehumidifying the air and any cooling that does take place will tend to condense moisture at the coolest point. You CANNOT do cooling with radiant type "heat". How well the system holds up will likely be a big determinant of the overall cash picture. I happened to use a conventional 50 gallon water heater for heating my entire house here in central New York state.Īs with most things up front costs can be high with geothermal though energy costs are quite low. ![]() it is not necessarily connected to radiant type heat but it does lend itself to it very well. Geothermal is just a way of generating heat. You will want water at about 120 deg F or so geothermal can easily generate that. I'll tell you that radiant heat is by far less prone to be dusty / dirty etc. ![]()
