Choosing Electric Underfloor Heating
Roma Heating supplies electric underfloor heating to the trade and to anyone fitting their own floor. We stock the lot: 150W and 200W heating mats, loose wire cable, foil mats for laminate and wood, in-screed cable, thermostats, insulation boards and the decoupling, tanking and adhesives that go with them. Orders for mainland UK go out for next working day delivery, or you can collect from us in Paignton. Installers and electricians can open a trade account for trade pricing and an extra discount online. If you want a hand sizing a job, send us the room and we will quote it for free.

We have been supplying electric underfloor heating for over 20 years. Stock is held here in Paignton, not drop shipped, so if it shows in stock it is on the shelf. Technical support is free, before and after you order, and a trade account gives anyone fitting regularly trade pricing on everything.
You do not need an account to buy. Every product is on the site at the published price and you can check out as a guest. The trade account is there for the people who come back every week.
What a Roma trade account gives you
Two types. A trade account is for installers with a business name and email who fit regularly. A stockist account is for merchants and outlets with a premises who hold stock and order most weeks. Both get trade pricing on everything, an extra discount for ordering online, and 10% off the first online trade order.
Apply on the trade account signup page and we aim to have it live within 24 hours.
Which output to spec
150W per m² is the secondary heat source spec, for most rooms on insulation. 200W per m² is the primary heat source spec, and the one for high heat loss areas.
Size mats to 80 to 85 percent of the open floor. In-screed cable serves as primary heating at 90 to 100 percent floor coverage.
Insulation and thermostats
Insulation underneath helps every system heat up faster and run more efficiently. Tile backer boards at 1200 by 600mm are the trade standard under tile, in 6, 10, 20 and 30mm, with a cement face for the tiles to bond to. XPS boards are the lower cost option, in the same thicknesses. Under foil mats the recommended underlay is Impact Plus, or XPS under rubber-backed LVT.
Thermostats are rated 16A, which is 3,600W. Above that you split the floor into zones with a thermostat each, or run the load through a contactor: 25A up to 5.8kW, 40A up to 9.2kW. We stock the RWI5 Wi-Fi thermostat, the RT5 touchscreen, the RM5 digital and the M100 manual, plus the relays and floor probes. For wet rooms we carry the shower trays, tanking and decoupling too, so the whole floor comes from one place.
Delivery and collection
Mainland UK orders go out for next working day delivery. Scottish Highlands and islands, Northern Ireland and the Isle of Wight carry a delivery surcharge, shown at checkout before you pay. If you are local, use click and collect from Unit 9, Trojan Industrial Estate, Paignton. We also ship to 16 countries outside the UK.

Electric underfloor heating questions we get asked
Can I put electric underfloor heating under laminate or LVT?
Yes, two ways. A foil mat laid dry on XPS or Impact Plus insulation suits laminate, wood and click floors with built-in underlay. Or a mesh mat or loose wire cable embedded in around 12mm of self-levelling compound. For rubber-backed click LVT over a foil mat, use XPS rather than Impact Plus.
Can it be the only heating in a room?
Yes. 200W per m² mats and loose wire are the primary heat source spec, and loose wire at 200W is recommended for primary heating on XPS or tile backer boards. In-screed cable serves as primary heating at 90 to 100 percent floor coverage.
What spacing for loose wire cable?
80mm centres for 150W per m², 60mm for 200W per m², which is two lugs apart in HC decoupling. Cable spacers hold the spacing as an alternative to HC.
What size mat do I order?
Size it to 80 to 85 percent of the open floor. Send us the dimensions and we will calculate the system size and coverage before you order.
Is there a warranty?
Yes. Register the system on our warranty registration page after fitting and keep the resistance readings you took before and after the install. Those readings are what any warranty claim rests on.
How do I get trade prices?
Apply for a trade or stockist account on the trade account signup page. Once it is approved, log in for trade pricing on every product, plus an extra discount for ordering online.
