The other type of floor heating is through hot water pipes embedded underneath the floor, like a geothermal heating system. Advanced thermostats can even give scheduling capabilities, allowing you to run the heating system at specific times of the day. The temperature of the wires, and consequently the room, can be changed through a thermostat controller. Some electric systems can also be used in the washroom since they are waterproof. The heat then transfers through the floor and heats up the room.Įlectric systems usually come in square tiles, which can be fit together like a big jigsaw puzzle. These electric wires heat up when electricity is passed through them. Nevertheless, you may still love the consistent heat!Īn electric radiant floor heating system consists of electric wires running under the floor surface. So, if you are someone who loves to huddle around a heater and get a cozy spot, you might find a radiant heating system just a bit different to your taste. In the sense that it does not heat from a direct flame, like a space heater, neither does it blow hot air like a furnace. The heat you feel is due to infrared radiation.Īs compared to other traditional heating systems, radiant heating is not a direct form of heating. If you are still confused about what is radiant heating, think of when you place your hand near a hot metal surface, and can feel the warmth even though you aren’t touching it. These pipes or wires can be embedded in floors, walls, or even ceilings. It does so by delivering heat directly from a hot surface, such as resistive wires or hot water pipes, to the indoor air. Radiant heating systems provide heat to the indoor environment using infrared radiation. Pros and Cons of Radiant Floor Heating Systems.To reduce the risk of condensation, it is necessary to take air out of the room from under floor during the cooling period.Radiant Floor Heating Technology & Options When air is taken into the room from under the floor, there is a high possibility that condensation will occur during the cooling period. In order to confirm the risk of condensation during the cooling period, the relative humidity of the underfloor space was measured. And, as the real-scale CFD simulation results, the heat load was reduced by up to 49% using the heat recovery radiant heating system. Previously, according to the results of model measurements on a 1/3 scale of the experiment module, when the temperature difference between indoors and outdoors was 20 ☌, a dynamic insulated floor radiant heating system was used to reduce the heat load by 23.8%. To achieve this goal, using 2 m × 5 m × 2.5 m experiment module measurement with and without dynamic insulation during the heating period, the heat load, ventilation rate, and thermal environment were measured. The purpose of this study is to examine the heat recovery effect and the risk for condensation by using the actual measurement and CFD simulation of the experiment module. This research proposes a heat recovery type radiant heating system that can recover heat radiation under the floor by applying dynamic insulation to the underfloor space. However, floor radiant heating does not use all of the energy used for indoor heating, and some of it causes heat loss to the underfloor space.
