Increasing Comfort While Reducing Heating Costs. You can enhance your comfort while reducing heating costs. It is well-known that the lower the temperature of the water used by your boiler to heat the home, the more economical it is. This is especially true for condensing boilers. However, the lower the temperature of the heating water, the harder it is for the heat to be emitted, as the temperature difference between the room and the incoming water decreases. This issue can be resolved by increasing the surface area of the heater. Beyond a certain size, this would be impractical with radiators. Moreover, multi-panel radiators increasingly rely on convection (heating the air) rather than radiation to emit heat. This is not ideal, as radiative heat at lower temperatures provides a more pleasant and better thermal sensation. The following describes how to install wall heating in an occupied apartment with minimal mess and disruption, which can be done as a DIY project. 8mm diameter heating pipes are installed between strips of drywall, then one wall is covered with an additional layer of drywall and the other with porcelain tiles.
Here, the heating pipe is already in the living room wall:
