The heat source is a Vaillant FlexoCompact 88/4 heatpump. The plumbers which installed the heatpump added Elysator Sanol (cleaning agent) and...

Hello,
I have a gas boiler in my apartment that heats a net area of 300 m2 with an underfloor heating system. The boiler has a capacity of 45 kW. There's no issue with the heating system, but I want to increase the hot water capacity. I plan to connect an external 200-liter boiler. How can I...
Bit of advice needed. Searched but couldn't find anything about Combi's and UFH with no rads.
Customer wants to have a combi, UFH but no radiators. Is it a good idea to have a single radiator on the system to provide a heat dump? Or should an auto-bypass suffice? If an auto-bypass then close...
I live in a property where underfloor heating was already installed by a previous owner. No manual was left, not even sure of the model/setup of our system (other than the fact that it’s a wet system linked to my boiler/central heating system & I can see these pipes behind a cupboard). It is...

I spotted this dark stain on my wood floor around 3 weeks ago, last time the underfloor heating was on was in December. Yesterday I switched it on again and it seems to be getting bigger. The stain is dark, no cupping or crowning, no sign of water or moisture. Any ideas whether it's a chemical...
Hi,
Having wet underfloor heating put in and been doing some reading, think pipe spacing is going to be 200 but read somewhere 100 from walls & sliding doors/bi-folds - is that correct ?
What distance would people recommend from kitchen units ? I have a run against one wall and then a 1200...

Hi
I have a 4 zone / 7 loop UFH system.
2 zones (4 loops) always get hot when the system is on when the zone thermostats and actuators are off.
The video posted shows when I turn on another zones the flow meters drop. (Kitchen prep and kitchen TV are the issue, two at either end of the...
Just wondering if there are any issues with adding water to a UFH via the boiler filling loop… reason being wanting to flush out some gunk from a loop and ventilate but don’t have access at the moment to proper hose connection adapter so I can plug mains water at the manifold.
Was thinking to...
Hi there
As you can see from the video below, our pump exploded. The question I have is, this pump is added to a firebird condensing boiler and when we found this mess the boiler and pump were stil operating but the pressure in the boiler was reading 0. Should the pressure switch have kicked in...

Hello,
I'm looking at installing a new central heating system with UHF on the ground floor and normal rads on the 1st Floor. The design was initially to have at its heart an Ideal System Boiler and a Telford Tempest 500l Indirect Cylinder but I'm considering changing/modifying this design to...
So vinyl instructions say limit is 30c, but that means it'll take longer to get the room hot, which i don't wanna wait. But I also don't wanna destroy the new vinyl I've just laid.
So I thought why not test it.
I have a sous vide machine which will heat water to a consistent temperature, I...
