Can I install a thermostat myself?

While underfloor heating installation can be completed by a competent DIY, thermostats require electrical work which must be completed by an electrician. All wiring and electrical work must be completed by a qualified and certified electrician only.


With the electrical connections, how many heaters can be wired to the thermostat before the junction box is needed?

When wiring underfloor heating to the thermostat, the maximum number of heaters that can be wired before the junction box is needed is two.


Why should I use insulation boards on a concrete base?

We recommend using insulation boards on a concrete base as this will improve the energy efficiency of your underfloor heating system. The floor will heat up quicker using less energy than without the boards. They act as a very efficient insulation barrier allowing the heat to rise upwards and not to be absorbed in the concrete, reducing the heat up time dramatically. The heaters will hence not heat up the concrete, but reflect and push the heat to the floor level. With the insulation boards, the floor on a concrete base will heat up within 30 minutes to an hour. Without the insulation boards, the heat up time will be significantly longer, anywhere between two to eight hours.


When using insulation boards, how are these fixed to the subfloor?

The way the insulation boards are fixed to the subfloor depends on the base type.
On a concrete base, the insulation boards are put down with a suitable flexible tile adhesive. The boards should be laid with staggered joints and once the flexible tile adhesive hardens, the joints should be re-enforced with glass fibre tape.
On a wooden subfloor, the insulation boards should be put down with a suitable flexible tile adhesive and as with concrete subfloors, the insulation boards should have staggered joints. When the adhesive has set, but not necessarily dried completely, the boards should be fixed using wood screws and washers. The insulation boards should be screwed down at 200mm centres, the screw washer fixing needs to be tightened into the board until the screw head is flush with the surface. After, the joints should be re-enforced with glass fibre tape.


I have installed under tile heaters, how long should I wait before turning on the underfloor heating?

Installing under tile heating involves using screed as tile adhesive. The underfloor heating cannot be turned on until the flexible tile adhesive is fully dried. A minimum of 7-10 days should be allowed for this to ensure that the adhesive is completely dry. Turning the system on too early may force the screed to dry too quickly, resulting in unstable subfloor.
It is important to follow the instructions and drying times advised by the manufacturer.


Is electric underfloor heating safe?

Unlike other types of heating systems, underfloor heating operates without moving parts, exposed heating elements.

Underfloor heating delivers a family-friendly and safe environment. No low level hot surfaces or hard metal edges that comes with a radiator system, which can create a potentially unsafe and dangerous environment for small children, the elderly or those vulnerable and at risk.


How much does it cost to run Warmup underfloor heating?

Warmup underfloor heating is very cost effective to run, it costs just 13p per day to heat an average sized bathroom.


Can I install underfloor heating without raising the floor?

Absolutely! Our electric heating systems would be the best choice.Our systems have been designed with a revolutionary, very thin heating element (only 1.8mm) to allow you to install the system without raising the floor height.


How many Warmup mats or panels can I connect to one thermostat?

Our programmable 3iE energy-monitor thermostat has an amperage limit of 16 amps. You can connect as many mats or panels needed as long as the amperage doesn't exceed this limit.
