Wärmer System Underfloor Heating Manifold Flow Meter/Regulator: Optimizing Heat Distribution

I was unsure when buying these regulators as the were different from the design of the old one (on the right). Videos online only show replacing the top part. From all the checking I made I could not find one like the originals, and the manufacturer of my manifold now supplies one which looks like the ones supplied. As this supplier provides both the regulator and the bottom "nut", it allows it to be used most manufold, however if its not 100% the same as your existing one, you will need to replace the bottom nut which is a more involved task.For the first time since my underfloor system was install these reglators finally don't leak, much better than the orginals.

Good quality and price. If you are replacing ones already on your system make sure these are the same size.

spare for review

I needed to repair the manifold and replace all aged flow meters. The items came next day, very fast. At the same time, I ordered one piece from the brand of the manifold which is with 2 letters. It came more than a week and without the nut underneath although they advertised it to come together. It looks like Warmer System is having same quality at lower price and quicker delivery. All the flow meters were working efficiently. I made the right choice.

Arrived quickly and was a perfect replacement for a leaking flow meter. Replaced in less than 30 mins and system back up and running.

Doesn't fit UPONOR manifolds. The lower valve seat is the wrong thread. The description doesn't state the thread size either.

Bought a couple of these to replace a cracked flow meter on my 2 loop manifold. It was a bit of an emergency as I discovered my heating system was loosing pressure because the cracked flow meter was leaking water. I ordered this on Saturday morning for next day delivery and it was indeed delivered on Sunday. I had them installed 30 minutes later and my underfloor heating in my kitchen was working again. They seemed identical quality to what they replaced and I was impressed with the price and speed of delivery.

These are ok, but we’ve found that some did break after a while. I’m not sure if the issue is with these or our system.? I think these were the best value ones we found.
