Heating a cottage is a separate conversation, how much trouble with this, if you do not carry out central heating, can not be described. Whatever we did, the house was always cool, around +18. We don’t know whose jamb it is, builders, or those who made us a coal boiler, but the result was such. Tormented by sleeping in socks, I decided to lay warm floors throughout the house.
Expensive, of course, but there was no strength to freeze. After a long search for a suitable option, I stopped at a warm field of Rome. And here's why: water floors erupt, infrared film burns. And in Rome it is positioned as fireproof, infrared, and is suitable for a shower (and it was cold there, too, so we decided to put it there). I decided not to take it through partners, I arrived at the plant myself, looked at the floor, talked with managers, and even with the director. All very nice people, it is clear that they not only understand what they produce, but also love their product, live it. Already a year and a half has passed, no complaints have arisen, all the promised pluses are present, I have not found any cons. It's warm at home.
This summer I will make a gazebo, with the expectation that in the winter it will be possible to make a barbecue. I'll put a warm rim floor there so that there is no ice.
pros
Fireproof, infrared, everything you claim to produce is true.
