The Warmup Loose Wire System has been designed so that installation is quick and easy. However, as with all electrical underfloor heating systems, certain procedures must be followed. Ensure you have read all technical specifications and you are happy to fit Warmup Loose Wire Underfloor Heating to your room. To install your Warmup Underfloor Heating system follow these 4 steps. Please note that this is a summary. More detailed instructions can be found in the Loose Wire Installation Manual
Smooth, clean and dry the subfloor surface. Paint the floor with Warmup Primer (you do not need to use primer if installing on an insulated tile back board). The light green colour of the primer will change to a dark green once dry. Avoid traffic once primer is down.
Calculate in square metres the size of the area to be heated. Use the Sizing Guide (found in the back of the Installation Manual) to correctly fit your heating wire into the space provided. Layout the heating wire in parallel lines. Begin at the start point and in U shapes go to the furthest point. Using the wire spacing markings as tape down points, secure the heating wire to the floor with adhesive tape. Once completed, tape down the entire length of the heating wire, positioning the tape centrally over the wire.
Follow the instructions supplied with your thermostat. Your underfloor heating system will not function without a correctly installed thermostat.
Check if the heating wire is fully taped and secured. Grout the floor as soon as possible as per the manufacturers’ instructions. Tile as normal, taking care not to damage or dislodge the heating wire.
  • The heater can be installed without the need for specialist tools or expertise (in accordance with local building code). It is important, however, that the Warmup Thermostat be connected by a qualified electrician.


Controlled from a smartphone, tablet or computer, the 4iE Smart WiFi thermostat learns how you use your heating and the unique way your house reacts. It automatically suggests ways for you to save energy, like what temperature you should set for when you’re not home and times you can turn the heating off early.

The smart ways the 4iE finds to heat your home more efficiently could save you up to £200 on the average UK energy bill.

Warmup are independent from the energy suppliers so the 4iE also works in the background to find better energy tariffs for you, which could save you up to £380 in addition to the savings you get from your lower energy usage.
