1. How long does the system need to be left before it can be turned on and used?
The system may be suitable for use immediately, depending on the final floor you or your customer has chosen.
For heating mats or cables installed beneath laminate or carpet, the system can be used once the preparatory levelling compound is dry. Under tiles or stone the system will be ready to switch on once the tile adhesive has fully dried, all drying times depend on the manufacturer’s specification.
2. Can it be run at full power straight away?
For heating mats and cables installed under tile or stone the system can be run at full power immediately.
If the floor covering is wood or laminate we advise slowly increasing the temperature by one degree per day until your desired temperature is reached.
3. Make sure the correct sensor is controlling the system
If you have underfloor heating in a bathroom or en-suite the thermostat will more than likely be positioned outside of the room. To make sure the system is working and heating the desired floor, check that the thermostat is reading the floor temperature via the floor sensor and not the air temperature. If the thermostat is set to read the air temperature it will be adjusting the heating based on the room the thermostat is in, and not the bathroom itself.
4. Avoid thermal blocks
To ensure your system runs as maximum efficiency make sure there are no thermal blocks covering the system. This includes rubber backed carpets, rugs or mats or laundry baskets in bathrooms, in fact even shopping bags left on a kitchen floor can cause thermal blocks!
5. How to minimise your running costs and get the most from your underfloor heating system
To make the most of your system and ensure your running costs are affordable, use your thermostat timer to control when the floor heats and set the temperature depending on your requirements. The most efficient way to run any underfloor heating is using a timer and programmed heating schedule.
Running costs vary depending on a number of factors such as how well insulated the room is, if underfloor heating is the sole source of heating and the thermostat settings you have pre-programmed.
An often underestimated factor in calculating your running costs is how well insulated the floor base is. Fitting insulation boards underneath a system can reduce warm-up time and increase energy efficiency. The faster the warm-up time, the cheaper the system is to run.
It can cost less than 10p to run 1m2 of CORGI underfloor heating at full power for six hours. A 3.5m2 bathroom can cost as little as £3.63 a month* to heat for 4 hours a day in the morning and afternoon. Plus the initial installation cost of electric underfloor heating is lower than wet (water based) systems.
*This running cost is calculated using an energy cost of 9.889p kWh based on Sainsbury’s Energy SE Fixed Price June 2016 v2 and a system comprising of 150W/sqm CORGI heating mats, installed onto thermal insulation boards under tiles.
