![]() furnace was 3 years old, paid $300.pilot light needs to be off the floor, min. garage (1.5 story) in 1991.poured floating slab on 1" thick foam.Ī few years later, put in NG forced air heating furnace (85% mid efficient unit) & sleeve AC unit (12,300 btu).on the cheap. but you can make a slab comfortable if you insulate it properlyīuilt my custom 24x30 ft. but not to todays standards - and I am very comfortable using panel radiators in the space. ![]() My home office is in my walkout basement - the slab was insulated. then do a heat load so you know how many BTU's the space is going to need. But I'm still going to use a hydronic fancoil in the HVAC and only warm the floors in the coolest part of the winter. I don't have NG service (propane or electric) so I'm installing a heat pump as I also want AC - the wood part of my studio will be a product called Warmboard and then I am going to use pex in the slab. so in the fall and spring they can overheat a space without proper controls. A concrete slab is a high mass floor - they take time to heat and to cool. Radiant floors work great in the same kind of big open space - with doors opening all the time. I don't think you will be happy with them in a new tight building. ![]() They work like a bonfire - heating objects. The tube heaters are fine in an open shop - like a car dealership with big open spaces and doors opening all the time. Can you tell me your floor temp in the winter? Mine usually never got above 37° or so. That way I would think the slab would stay warm and once the room was up to temp it should not cost any more to heat than the in-floor heat. ![]() Steve in MI: Good point about heating 24/7 with normal forced air heat and a good insulated floor. A mechanic friend of mine has it in his garage and he said it is comfortable at about 55° if you are actually working. I love the idea of in-floor heat for that reason and I would assume I would keep the heat on 24/7 in the winter months. I will be in the shop a lot more and I do not want to lay or stand on a cold floor. I plan to retiring in a few years so I am building this garage with that in mind. But the floor never got warm and even with good boots on I would have to go inside to warm up. Before we moved, I had a 2 car garage with a normal space heater and I would just flip the heat a hour before I started working. I am in Minnesota so I need to heat the garage for several months in the winter. ![]()
