Many people assume that the underfloor heating cost of a whole-house system will be higher than their gas/oil furnace, simply because gas is currently cheaper than electricity. But it's simply not the case. Running costs will always depend on the room size and the running time, as well as how well the room is insulated. To get an accurate idea of underfloor heating costs, see the table and notes below.
Warmup has extensively tested its underfloor heating systems, running under normal operating conditions, in a test laboratory built to EN442-2 specifications. The data collected from this testing allows us to give you piece of mind by telling you exactly how our products perform in a given situation, letting you choose the product and installation method that is right for you. Warmup is the only manufacturer with this information, and the only company that can answer your electric underfloor heating costs questions with 100% accuracy. Please note that these tests were performed using Warmup heaters and that this data is accurate for Warmup heaters only.
During the heat-up period, as the floor reaches its set temperature, the heater is running at full power. After this period, the heater needs to run at only half-power to maintain the set temperature. Simply put, the faster the floor heats-up, the cheaper the system is to run. By properly insulating your floor with Warmup Insulation Board, you can reduce the heat-up period significantly thereby reducing the overall underfloor heating cost by as much as 50%.
According to independent energy watchdog Energywatch, since 2003, gas prices have risen by as much as 92%, while electricity prices have only increased by just 54% in the same period. As electricity is almost 100% efficient at the point of use, whereas gas boilers waste energy by way of the flue and transport throughout the walls, gas users will soon be paying much more and receiving much less. The typical lifespan of a gas boiler system is 10 years, according to industry estimates. Our underfloor heating for tile floors have no moving parts to wear-out and come with a LIFETIME Warranty. When maintenance costs are added to the equation, the annual underfloor heating cost of a radiant underfloor system looks remarkably attractive.
Adding a zone to a house that uses electric underfloor heating is as simple as adding a thermostat. Gas systems tend to run all the rooms of your house at once, whether you are using them or not. Electric systems, however, can be set to heat an individual room where and when you need it (a bathroom for an hour and a half in the morning for example). By tailoring your system usage according to your lifestyle, you can reduce the underfloor heating cost and enjoy substantial savings.
