Can radiators be used inside my house instead of under floor heating?
A. Yes, they can, but you will need larger radiators, sized for the typical 45° C to 50° C water temperatures obtained from heat pump systems. If your house is really well insulated they may be suitable, but check to see how big they would have to be and the space they would take up. There is now available a wide range of very stylish Italian die cast aluminium, high output radiators. These are very efficient and smaller than conventional radiators. Upstairs is usually less of a problem as bedrooms are normally kept at lower temperatures.
