Underfloor Heating Accessories

Peel-and-stick mats like the Warmup DCM‑Pro V3 give you a uniform, ready-backed surface that's quick to lay across a single open area, the 14m² size suits a medium bathroom or kitchen run. Matting rolls such as the ProWarm ProGrid+ (15m²) are more flexible for irregular spaces or where you need to cut and route around fixtures. The trade-off is that rolls can be better for shaping but may need more careful positioning; the DCM‑Pro is convenient when you want large, continuous coverage.

That Warmup fitting is specified as 3/4" Eurocone to 16mm compression, so it's made to join a 16mm heating pipe to a 3/4" Eurocone valve tail or manifold connection. If your system uses 16mm distribution pipe and standard 3/4" Eurocone fittings, this part will give a direct mechanical connection. If your pipes are a different diameter or use another cone size, you'll need the matching compression or adaptor.

The Wall & Floor Primer is used to improve adhesion on surfaces before you place underfloor heating components or subsequent screeds and adhesives; the 1L size is aimed at small rooms or patch priming. Coverage varies with surface porosity, but a 1L is typically enough to prime a single bathroom or to treat small problem areas. Use it where substrates are dusty, porous or have been recently repaired so adhesives and mats bond reliably.

The 90‑metre glass fibre tape is for reinforcing joints, sealing overlaps and strengthening edges around underfloor heating mats or where boards meet. Because it comes in a long roll, one length will cover the perimeters and multiple joints in several bathrooms, a 2.5m perimeter around a small bathroom uses only a few metres. It's a simple, low‑cost way to stop cracks propagating into your heating layer and to give a neat finish to taped joins.

You'd keep the ProWarm repair kit (the current product price) as a contingency for minor damage to electric heating cables, it's a cost‑effective way to restore a small fault without replacing the whole element. It's designed specifically for electric systems, so it's a sensible spare if you own electric underfloor heating. Bear in mind such kits are for limited, local repairs; extensive damage will still require professional assessment or replacement.
