Hi All,

I've got a Worcester 4000. Never had a combination boiler before. After 14 mths message came on saying pressure was 0.9 and to top up. I topped it to 1.3. Four months later (today 28th of February) it's reading 1br. Boiler has been used pretty much constantly through the winter. Is this normal? I've checked all radiator points for leaks but not found anything.
The boiler is on my elderly mum's so not worried about it.

Thanks

Hi,
I Have a Honeywell 3 way power head that the motor seems to have died, my question is can the power head be replaced on this particular model or will i need to change the whole valve?

I've got a Worcester Greenstar 38CDi Classic ErP with a keyless filling link. One of the rads has a tiny leak so every few months I have to top up the system (and bleed a rad upstairs). I should get the leak fixed but since it's so minor I haven't bothered.

My actual problem is that the system is SO SLOW to fill. It takes around 30 mins of holding that stupid blue lever to get the pressure to just over 1 bar.

In the manual it shows the blue plastic fill lever can be pulled down a full 90...

 

I have a problem with my system when both CH and HW are on. The CH seems to take priority and the HW hardly warms up.

To get the HW to heat I usually need to turn down the heating on the thermostat or turn it off on the programmer.

Is there a way to make the system give priority to the HW over the CH.

The radiator in our bedroom does not warm up. I removed the thermal adjusting "thing" to expose the pin. The pin simply slides in and out as I would expect it to do. In or out, the radiator does not warm up. The radiator in the kitchen was the same, but removing the "thing" and pulling the pin out, gently of course, corrected the radiator and it functions normally now. What should I do to coerce the radiator in the bedroom to begin functioning again.

Hi guys quick question,

My central heating system is over 40 years old. A mixture of 15 and 22mm pipework to and from the boiler (which is 15 years old), while the rads are served via microbore pipe from the two distribution trees hidden away under the back bedroom floor.
A few weeks ago, the pipework became blocked and fortunately a local plumber managed to clear it. He gave me some instruction to clean the system, which I've followed closely:
1 - Refill the system with plain water, run for a day, then drain -...

 

Hi

I have recently bought a house which is 17 years old.
There was a small leak from one of the radiators So I took the pipe off and drained the radiator and the water was black/brown.

I took the radiator off and flushed it out with a hose pipe out the garden but it's got me thinking and I now want to clean the whole system the best I can.

Just looking for some advice really on what the best way to do this is as I have never done it before.

Shall I take each radiator off one by one and...

 

hi,
For newer boilers with variable speed (modulated) water pumps for central heating. Should there still be bypass valve when all radiators have TRV's. Plumber saying not needed anymore.

I had a new Vailant boiler installed 2 years ago, and the system has needed a motorised valve replaced twice and now the Onyx pump has started making an irritating and irregular high pitched squeaking noise.
Can anyone advice me what the fault could be ?

Many thanks

Hi

I have an unvented Megaflow system, which is 10 years old. Since October last year we have had low pressure in the shower, I have had to take off the shower mixing valve every few weeks and clean out what I believe to be scale from the hot water inlet mesh (see photo attached) . The pressure then returns to normal.

The TPRV valve is slowly dripping in the tundish, even after i reset the airgap via the instructions on the front of the megaflow, could this be causing the buildup?

We...

Hi,
Has anyone used a company called Cohostore before ?
Prices seem good but they claim to have a warehouse in Glasgow while their phone number is a Dover area code. Also when I order something I get sent a payment link with a different company name attached. Any help appreciated

Hello, I put x400 in our system at the end of November, intending to leave it for a few days but took ill and it's still in there. Now on the mend I want to drain it soon & I've just emailed Sentinel who replied:

"The maximum recommended time for Sentinel X400 to be in the system prior to flushing is 4 weeks. If it has been left in longer it will not damage the system but may not have cleaned as efficiently"

To me that's worded oddly as generally things carry on reacting (till they're used...

 

Hi all, we bought a house 3 years ago that has underfloor heating on the ground floor but the way it has been installed does not seem to conform to any of the accepted standard. It has a newish oil boiler that is running the UFH temp at 75 (yes I know that is too high) but the floor still remains tepid at best. It is an Uponor manifold and I have just changed the valves and flow meters and flushed and vented the circuits (there are 9 circuits). No change still tepid. However, I am wondering...

 

I found various makes of TRVs had been fitted to the radiators by the previous owners. One make in particular, Westherm four, all have the same problem with the pins. The pins aren’t stuck, they move freely up and down when using a pair of grips but they stay in the up or down position and don’t pop up under spring pressure. I’ve banged them a bit and sprayed them with WD40 several times over several days but the pins still won’t spring up from the down position.
I guess they are faulty but...

 

Good morning Gents!

I keep getting asked by a loft company to move header tanks in the loft.

Long horrible horizontal pipe runs.

This of course creates tremendous ball ache with air locks etc.

The heating is always converted to unvented but the hot water.....

Can someone point me towards regs, guidance, standards, literature etc saying you should not do this?

I want something to wave in their face.

Many thanks,

Jerry

I have had 7 Stelrad softline radiators start to leak around the weld where the elbow joins the radiator panel.

As part of a renovation I have replaced all the radiators and 90% of the copper pipe with Speedfit barrier pipe.
System is treated with Fernox F1 and has a Magnaclean Twin Tech filter which is checked annually when I top up the F1.
Water has been tested by Fernox and was OK.

Hi

I own a new build property (well 4yrs old), and moved in 2 years ago.

When I had the first boiler inspection, the chap mentioned that the systems in new builds were a bi 'different'.

The oddities (that I see it as) ready to be educated here!, are:
-The radiator in the upstairs hall way is connected to the downstairs thermostat and not the upstairs thermostat.
-The bedroom radiator does not have a TRV on it - so, it is 'always on'.

This isn't really creating a problem; in fact we...

 

Hiya,

I have an Ideal Classic FF230 in my house with the sealed system kit and I’ve been having pressure issues with it the past few weeks where it comes on, the pressure steadily rises to 3 bar and then vents via the PRV and then when it cools down the pressure is zero.

I’ve had British Gas come out to look at it twice under the homecare agreement, the first guy said it was the expansion vessel and removed it, re pressurised it and then put it back and said it was all fixed and left...

 

Hi all

I have Vaillant 624 running 3 circuits; a Telford unvented tank and then 2 hearings circuits (downstairs & 1st/2nd floor).

This is currently all run with 3x 2-port valves in and-plan+ configuration with Hive controls. I did have LLH fitted which was removed about a year ago for some trials with a 637 boiler. Now I’m thinking about getting this reinstated but also upgrading all the controls to Vaillant to utilise better modulation and control of temps for each circuit (possibly hw...

 

Hi, can anyone recommend a controller for wireless TRVs that can set on off time for individual TRV using a phsical control panel with it's own interface/screen that does not need a smartphone app to work and can be used stand alone?

Hi everyone,

I have a customer who needs a new system boiler, currently has a 22kw which I've roughly calculated as enough heat output for the heating (its a 6 bed victorian terrace house), but this doesn't take the 200l unvented cylinder demand into account. Currently the system is setup on S plan, with no priority domestic hot water. When I fit the new boiler, I would like to try and set it up with PDHW for obvious reasons, but I'm not sure if this is possible with the existing two x 2...

 

Had a new ideal vogue max c32 boiler fitted. The programmer has an “efficiency level” button that says it’s around 9-14%. That seems low.”, worried it’s installed incorrectly

Anyone have same issue?

I bought one of these:

and I am using it to control the temperature of my hot tub, and it works great. Does anyone know of a device like this that does not use plugs but rather can be wired in? I am looking for something to control my cylinder, that can be programmed down at night with the ability to set the differential. This model works great for the hot tub and you can set the on/off temperature as you like in...

 

I had an engineer today added inhibitor in the boiler filter via Magnaclean when he did the boiler service after taking off the filter.

But before the engineers all added inhibitor in the radiators, and I searched online that majority information shows the inhibitor should be added in radiator.
So is it ok or right to add inhibitor in the boiler filter via Magnaclean?

Thanks for any input!

I have a wall mounted thermostat which is connected to a 26 volt supply from my Glowworm 24ci boiler.
I would like to replace this thermostat with a programmer so i can time when the heating comes on and off.
Currently the heating is turned on/off using the thermostat.
Can the thermostat be replaced with a programmer that works off this 26 volt supply or is a mains supply required.
Any suggestions which programmer i should use.
Thank you

Hi all,

When I use my hive thermostat in the way I think your supposed to. I.e. set it to a desired temperature then don't touch it. The combi boiler seems to cycle on/off in short succession as can be seen in the attached image of the heating history. Does this indicate what's called short cycling? In a way it makes sense to me that the boiler is doing this if what is happening is:
-temp drops below set point
-thermostat triggers boiler
-room temp is raised beyond set point in short...

 

Hello,

We have had a bad sewage smell coming from the downstairs toilet for the last few years. We had a new suite put in back in 2019 which didn't resolve the issue. The smell seems to be coming from the sink side of the room. I have removed the sink unit now and can see that the waste pipe just seems to fit in a hole in the ground. The pipe in the ground also seems to be damaged. Is this likely to be the cause of the issue (potential stagnant water not draining properly into the main...
