Warmup Underfloor Heating Accessories

Warmup accessories are engineered to integrate seamlessly with Warmup systems and are made to Warmup's high standards, which gives you the best long-term compatibility if you stick to the same brand. Some items, such as the 3/4" Eurocone to 16mm compression fitting, use common industry sizes and will physically fit other manifolds and 16mm pipes. If you already have a manifold with 3/4" eurocone ports and 16mm pipe runs, that fitting will connect directly. Using matching Warmup parts reduces the chance of leaks or performance issues, while mixing brands can work but needs careful size and material checks.

The Warmup Wall & Floor Primer (1L) prepares porous substrates so adhesives and levelling compounds bond properly to floors or walls before you lay heating mats or screed. The 1L size is convenient for small rooms such as a bathroom or kitchen run; one bottle often covers the area you'd prime before applying adhesive. Good priming reduces the risk of lifting or poor adhesion later, so use it on new screed, plaster or very absorbent surfaces.

That description means the fitting has a 3/4" eurocone threaded end to screw into standard manifold ports and a 16mm compression end to accept 16mm underfloor heating pipe. In practice, if your manifold uses 3/4" eurocone connectors and your pipe is 16mm, this single fitting joins them without adaptors. It's designed for wet underfloor heating systems and saves time on plumbing runs where those sizes match.

For fittings, count the number of pipe connections to your manifold, a small bathroom often needs two to four circuit connections, so you'd buy the same number of 3/4" eurocone to 16mm fittings. Primer is sold in a 1L bottle; for a single small bathroom that one bottle will usually be enough to prime the floor before adhesive or levelling compound. If you're treating several rooms or large areas, increase quantities proportionally.

Yes, Warmup designs its accessories to simplify installation for both professionals and DIY enthusiasts, with familiar sizes like 16mm pipe compression fittings and practical 1L primer containers. The components are made to high standards so you get reliable, long-lasting parts even if you're doing the work yourself. Just make sure you match the fitting sizes to your manifold and pipe, and follow manufacturer guidance for safe, watertight connections.
