This is a series of some of the most common technical questions our 24/7 all year round technical support receives. We answer your questions within the series and look forward to helping you with any other underfloor heating questions. To ask a question yourself, please leave a comment or contact us at email@example.com.
Q: I am considering between different heating systems. Can underfloor heating be used as a whole-house heating system?
A: Using underfloor heating as a whole-house heating system has several benefits from decreased energy consumption to freeing living space as radiators are not needed. In many cases, underfloor heating can be used as the primary source of heat as long as the rooms have the correct levels of insulation. A heat loss calculation needs to be carried out to establish how much heating is needed to heat each room and whether the insulation levels allow underfloor heating to be used as a whole-house system. Heat loss calculations are normally carried out by a builder, an architect or a heating engineer.
There are also heat loss calculators available online which can be used if the insulation levels are known to give guidance on heat loss levels.
Q: I am testing my underfloor heating to see if it works, what setting should the multimeter be on to test floor probes?
A: When testing electric underfloor heating and checking the resistance of heating cables, a multimeter should be used to test both the heating element and floor probe before, during and after installation. This will tell you whether the heating system and/ or floor probe is working correctly and has not been damaged by using the Ohms scale. To test the floor sensor the multimeter should be set to 20 K (20,000) ohms. The reading you get back will depend of the model of thermostat installed.
To test the heating element the multimeter should be set to either 200 Ohms or 2K (2,000) Ohms dependant on heater size. Resistance readings for all our heaters can be found in the relevant Installation Manual for that heater.
Testing an underfloor heating system before and during the installation is important as it will tell you whether the system has been damaged during install. Testing the system before installing the final flooring will give peace of mind in knowing the heater is working and will ensure that no damage to heater occurred during the laying out of the heater. Should the heater have become damaged during the installation, Warmup’s outstanding SafetyNet™ guarantee will replace the heater for free. Warmup will provide another of the same make and model for free, providing the following the terms and conditions have been met.
As part of Big Energy Week (Jan 16-21) we will be joining in with consumer organisations, energy suppliers, switching sites and the government to let you know just how you can lower your energy bills. Improve your home heating and save money by using Warmup electric under floor heating. In a series of blog posts we will [...]
The benefits of electric underfloor heating and comfortably warm rooms and feet are now widely known. Lesser known however, is how the advantages of floor heating can be extended even further by way of effective insulation. Extensive research conducted by Warmup on the impact of proper insulation on energy usage has revealed some note-worthy results. [...]
