And since in-floor heating systems are restricted to a maximum temperature, homeowners can be certain that their flooring will never heat up to a dangerous level. Of course, as always, contacting a professional electrician who can provide more detailed information about any safety concerns is a good idea, especially if it can give you peace of mind. In-floor heating, also called radiant floor heating, is most commonly available in two formats. The first is a hot water system where tubes are placed under flooring with hot water running through them, warming the floor.
The second option is an electric system where wiring is installed under the floor and, connected to a power source, will warm the floor using electricity. Both systems are efficient and provide consistent heat evenly across floors, though they also have different pros and cons. Water-based systems, also called hydronic floor heating, are typically the most efficient option over the course of time; however, installation can be complicated and expensive as a boiler, pump, and gas lines are involved.
These systems are also best installed during the home building process, though retrofitting it in an existing house is possible. Electric floor heating, on the other hand, is easier to install and therefore less expensive to set up. It warms floors—and even rooms—just as well as hydronic systems, but depends upon electric power to run, and electricity can be expensive as well.
Yes, provided that the layers between the heat source and carpet are sufficient conduits for heat. The warmth from your underfloor heat source should pass as quickly as possible to the surface you want to warm.
Therefore your carpet, including its backing and padding, should have a low level of thermal resistance, making it easier for the heat to rise. Luckily, carpets and padding have a thermal resistance rating R-value which takes into account the fiber, yarn type, pile height, and weight of carpet, as well as the thickness and density of padding. HVAC professionals recommend that your carpet R-value be between and, with padding, should total no more than an R-value of 3.
When using radiant floor heating under carpet, care should be taken to ensure effective performance of the system. Everything above the heater, including underlay, overlay and final floor finish need to be in the limits set below. The typical carpet is 1. It is not recommended to install underfloor heating with carpet if the limits below are not met. This may hinder the performance of the system and result in the system not working as desired. In order to achieve an efficient system, the subfloor should be insulated.
This means that the concrete or plywood base on which the heating system is installed on should have additional insulation. Warmup insulation boards or Warmup insulated underlay are designed to give the best performance for the floor heater to provide heat through the underlay and the carpet on top.
Floor heating is the modern heating solution — creating the perfect temperature, making you feel warm and comfortable from the moment you enter the room. The Company. Contact Us. Media Content. When choosing your carpet flooring, attention must be paid to the overall thickness of any materials above the heater including any underlays and overlays.
The underlay should have low thermal resistance and the carpet should be hessian backed to promote efficient operation of the system. A felt underlay should not be used as it may create a thermal blocker hindering the performance of the system. Any type of carpet padding can be used as long as it has a density of 6 pounds per cubic foot or more. Most good quality rebounded polyurethane rebound and prime polyurethane are 8 pounds per cubic foot or more. When installing the system, the concrete or plywood base on which the heating system is installed on should have additional insulation.
This promotes the efficient operation of the system. Warmup insulation boards or Warmup Insulated Underlay are designed to give the best performance for the floor heater to provide heat through the underlay and the carpet on top.
