The last thing you want is an inefficient system. That is what I would truly be more concerned about, getting the proper flow rates, delta T and water temperature. I would call and get some more quotes, but a lot of plumbers do not mess with it or have the experience laying it.īut What is more important is getting the proper load calc and design. Have yet to buy pumps or a separate tankless, but that will be around 3000$ more. I skipped the main level hydronic.Įnded up spending somewhere around $1100-1300 with manifolds and piping for the basement and 2 days of me laying the circuits. about 14$/sq ftĪfter being shocked by that, and having experience doing hydronic, I ended up doing my own design / load calcs with LoopCAD for the basement and installed it and the manifolds myself. for tubing and labour) Keep reading for an in-depth breakdown of the different costs of in-floor heating. I had a quote of 70k, for 2984 sq feet on main level with viega climate panels, and 1850 sq feet finished basement, piping laid in slab. An electric radiant heating system is cheaper. If you opt for a larger boiler, the price can double or even triple. Would be interested to see who that quote was from. Radiant floor heating cost can vary depending on the system but averages 3,867 nationally, typically ranging from 1,687 to 6,032. This can set you back anywhere around 1,500. It seems on the high side if it's 4200sqft, and it's probably about right if you wanted lines running under your basement floor as well. So your $71k number seems really high if it's just 2100sqft. There isn't anything technically complicated about it, it's just the labor to install the plates and run the lines (it took these guys about a week to run it all). Truth be told, now that I see it going in, it's pretty easy. Then it's just running the water line, and hooking it up to the zones & boiler. When installed in a small 35 square foot bathroom running a total of 8 hours a day, the system would only use 4.2 kWh per day. A typical electric floor heating element produces 15 watts per square foot. We needed about 12 boxes of the aluminum heat spreading plates to cover the 1500sqft ($300/box = $3600). Electric Radiant Floor Heating Cost to Operate. The cost to cover ~1500sqft (we're not doing hydronic floor heating in the 500sqft in-law unit above the garage) is ~$25k (including boiler & 2 zones). Hot-water radiant costs more to install than other types of heating systemsfrom 6 to 15 per square foot depending on the method, whether you’re starting from scratch or retrofitting, and where you live. Are you saying you want radiant floor heating in the basement floor, or just the one story above the basement? If so, how much is that one story above the basement? Is that 4200sqft, or is it half of that (2100sqft?)įor reference, I'm in the process of a new build and they are putting in hydronic floor heating right now. This quick calculator will tell you the cost to operate an electric radiant floor heating system by using the power consumption of the underfloor heating system and the energy costs in your area.
