Hi, I am having to replace the powerhead of a Honeywell 22mm Motorised valve, model is a
Honeywell V4043H1056 (272848)
it is not that expensive retailing at approx £72 but Corgi do one for £42, is the Honeywell worth the money, the one I have has lasted less than 10 years!
Thanks
Andy
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 large kitchen/dining area and I've measured the temperature. It's an interesting pattern... up and down.. and up and down... even though the thermometer is set at a constant temp. No night time set backs or anything like that... just inertia.
We have a GSHP and ancient controls (see...
Hello I'm new to the forum and wanted to ask a question after having a good read. House is undergoing a complete renovation and new pipework needs to be installed for the heating system. The current boiler is a WB Greenstar 34CDI combi boiler and is not very old so I wanted to reuse this in a...
My daughter has just had a new boiler, her system is radiators to upper floors and underfloor to all of ground floor. Despite the valve serving the underfloor being turned up to a high temperature and the pipe leading to the pump being very hot the flow and return pipes on the manifold are only...
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...
Hello all, hoping someone could help me with this, Boiler pressure is 1.5 bar, but when we turn on UFH pressure drops to 1 bar. then when we turn off UFH, pressure on boiler goes back up to 1.5 bar?? any help much appreciated
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...
Hi
We have an UFH system part of the house (large kitchen / dinnner and utility room) and then Rad system for rest of house (10 rads).
We have noticed in this recent cold weather when both UFH and Rad are on (ie thermostatic driven) the UFH is robbing all the hot water and not getting round...
I have NuHeat UFH system, and this has no Thermostatic Blending valve on the heating circuit. (Heat Master II cylinder has pick up coil)
Nu-Heat System installed -
This means I can't run store above 60C due to risk of overheating UFH pipes.
I want to add a Thermostatic Mixing valve so have...
Hi all,
I have a Heatmiser UFH installation, 7-8 years old now. This week we noticed that a few of our heating zones were not warming up, even though the thermostat was showing the flame symbol. They were working fine last winter. I knew from when I looked at the installation in the past that...
Hello all. First time posting so apologies if this is answered elsewhere.
I am close to completing a purchase of my first flat, an ex-council place from the 1960s built in the usual concrete slab and brick.
At present there is some ghastly pipe work for the radiators sprawling round every...

System is as per drawing

I have a UFH manifold from Wundatrade with a Grundfos pump. The pump feed has a mixing valve which has a hot inlet from the thermal store, and a cold inlet from the return manifold. In-between the mixing valve cold inlet and the return manifold, is a tee which returns the cold water to the...

So I posted a while back regarding my 300ltr unvented cylinder not seeming to keep any volume of water hot for very long.
Could it be the system boiler is not powerful enough? I have approx 220m2 of underfloor heating and the hot water cylinder’s . Does anyone know if Worcester Bosch Greenstar...
Hi all,
I have recently had a UFH circuit added to my existing CH/HW system and had a question on performance when UFH and CH are operating at the same time.
My boiler is an Vailliant EcoTec Plus 630 and for a number of years this was running with a CH and HW loop only. Each loop had a 2 port...
I have a OMNIE designed wet underfloor heating system on three floors. Ground and 2nd floors work well with those two floors having a single manifold and recirculating pump for the various zones.
On the 1st floor the rooms are split over two manifolds each with its own recirculating pump...
Hi - please help me. I think our UFH is installed incorrectly. Please see pictures (if anyone needs more images I can take them). UFH-Full-View-Labelled - https://ibb.co/3C0MsKD
The problems we have are. The heating takes FOREVER to heat the rooms. The circulation pump is running all the...
Hi,
I have a combi boiler that supplies hot water to two ufh manifolds. We only have ufh and no radiators. I am trying to find the most efficient way to heat our home. What would your recommendations be on the following ways to set our system up.
A) Set the ufh mixer to max so it isn't doing...
As above. Ideally it'd be less.
This might be the wrong forum for the Q. But the system is actually working fine. the system is in the 15mm insulation boards above a tar subfloor.
Are my next steps to start getting cavity wall insulation etc etc?
