Hi,
I have a 3 storey house built in 1904.
We put UFH in the house about 20 years ago. Works well with newish gas boiler.
Just curious... I know heat pumps are meant for tightly insulated modern house ... but..
Question: Given that my UFH is always at a low temperature - Could I feed UFH with...
We’ve had a UFH system installed as part of our home renovation which is run alongside our existing radiators. Some of it is in rooms with LVT flooring which means we’ve got to be careful with water temperature (floor temp limits are set, but can easily overshoot if water is too hot).
Our...
Hi. Really strange one. Our underfloor works lovely. But once it clicks off, it stays off, resolutely. This can be either from the zone thermostat or, strangely, after we've showered using water for a megaflow tank. It's speedfit manifold but I think problem might be with JG wiring...
Moved in recently and inherited a combi boiler with 2 zones setup, one to the rads all around the house and a second to the underfloor heating in the kitchen. When the kitchen zone is activated, the boiler kicks in, the flow pipe heats as expected and the heat only travels through the pipework...

Hi!
I have mostly underfloor heating in my house and one new radiator and two old. A bit of metal pipes and three manifolds, but mostly PEX-pipes.
The heat source is a Vaillant FlexoCompact 88/4 heatpump. The plumbers which installed the heatpump added Elysator Sanol (cleaning agent) and...
Hi all. If I may, I'd like to ask some beginner's questions.
The situation: We think we may have air trapped in our UFH system. Therefore, we're considering refilling the circuits. However, there are a few details we need to clear up first.
First of all, we need (?) to buy some hose end...

Hi guys - hoping someone can help...
Have a 12 yr old Wunda 2-zone wet underfloor heating system which is starting to fail (zone heating up despite stat being off) and a generally old and inefficient thermostat system.
Difficult currently to get anyone to come have a look at it, managed to get...
This morning I heard knocking coming from my bathroom sink drain! The central heat outdoor unit is just outside the wall, and it was running. I went outside, but it seemed fine. When the heat unit went off, the knocking stopped. What the hey? I have a video, but I didn't see a way to add it to...
We have a Daikin Air Source heat pump feeding our hot water and under-floor 8 port manifold heating system.
The Daikin has just had its annual service and the engineer commented that the water looked discoloured and that the inhibitor needed replacing??
Is this an easy procedure? I'm pretty...
Our pulsar infloor was installed in 2006 and worked well until a total heating failure in 2020. Following its repair and a new bolier the infloor has not worked properly. Several different plumbers have attended but still no improvement .Are there pulsar specialists out there in the plumbing world?
I have a client with 5 manifolds that are Pulsar Direct supplied .I know Pulsar direct are no longer. I have a few with leaking TRV (RBM -TL50) pins. How easy is it to change the pin side of the valve. . Are they standard or specific to the manifold?
Where would I look for spares. Just had 'we...

Similar to radiator dT's, is there a way to mathematically calculate the UFH pipe centres required to satisfy a given room's heat demands?
150mm-250mm centres are banded about online, with no real explanation, obviously smaller centres allow for lower water temps, but there must be a more...
My Altech CPS 130-5 has stopped working and plumber said he can’t find this pump anywhere! Is this product still being made as it was installed about 10 years ago? Can anyone advise where I can buy it or recommend a similar product? Otherwise the whole ‘kit’ needs replacing and I’m trying to...
I have a Neura heat pump and my thermostat has failed (Theben RAM 797 b). I'm looking to replace it with another more modern one I can use with an app etc.
My question is, can I replace it with any thermostat or do I require a very specific type thermostat to run the heat pump?
Thanks for...
Are there fundamental differences in some of these TMVs?. The attached one, below, would seem to be the better type where a shuttle moves to balance the hot&cold flows, as it increases one flow it decreases the other to keep the mixed flow constant, necessary say in showers etc. I have seen...
