Hi all ,
on a pressurised heating system is it ok to take a flow and return up into the loft and down again to install new radiator also would it be prudent to put AAV at the high point , thanx in advance .

I have a greenstar 35cdi combi boiler that when the thermostat calls for heat. It will fire up heat to temp and then drop down to 41* on the boiler display and then kick back in again.
I have checked all wiring and the zone valves. What else could it be? anyone seen this before
Hi,
The outlet of all my radiators are at 55°C, but the boiler keep showing the Return Temperature is 60°C (and keep raising at 1°C/min rate)
Also the flow temperature keeps going up above the set point and when it reaches +5°C above the set point, the boiler shuts down (even before the room...
I recently had a new 2023 Vaillant ecoTec plus 630 (30kW) system boiler installed along with a Low Loss Header (LLH) in my house. I have 21 rads in the house and a room with UFH. The LLH was introduced as I was finding (before the LLH was fitted) that my old boiler (Vaillant heat-only boiler)...
Hello.
I've just replaced our old Potterton EP2 CH controller with a Drayton Wiser HubR (& peripherals). The old backing plate wasn't compatible with the new universal one, but the wiring was pretty close AFAICT (N, L, 1, 3 & 4 connected) .When I first powered it up but didn't have any TRVs...

Hi all,
My pressure is stable at 1.5 when the boiler is off, but if I switch it on, the pressure rises as expected, but once switched off it will only drop back down to 1.6. This happens exach time the heating is switched on so eventually it gradually rises to above 2 bar and I have to drain...
Hi
I am somewhat confused.
My daughter has a combi boiler bought 2-3 years ago and has it timed to come on in morning for an hour and at night for a few hours using "auto"? mode
I had been brought up to leave boilers on manual and set the thermostat low at night to prevent pipes from...
I have been facing central heating low pressure on unvented hot water RM Cylinders but can't see any leak on the PRV, expansion vessels and plasterboard celling.
I have got unvented pressurized RM Cylinders hot water system with 27KW Worchester gas boiler with expansion vessels .
When...
I need some help and advice with a boiler issue. We have F29 and then F29 appearing on our new boiler. This happened after few days where water was dripping from the condensation pipe. Our regular gas engineer(who installed the boiler) was not available and will be in a couple of days. The...
Apologies - I am not a plumber - not sure if it is ok to post here but...
It's freezing and my boiler is not working so, I wonder if anyone can offer me advice?
I have an old Glowworm Micron 30FF. Must be about 18 years old. The whole system needs replacing if I am honest - the tank it fills...
On my Valliant eco tec boiler the pressure guage is on red when cold . I drain a radiator to correct to pressure and it works fine and stays in the safe zone . When I switch boiler off the next day it’s back in the red
It could be one of the valves leaking .
Can I take the loop off , which...
Hi.
I believe this boiler can be changed to a system or combi. Does this mean the hot and cold tails have to be blanked off??
Also the horizontal flue does not come with self tappers compared to another brands I've installed in the past.. Im I right in saying it's almost like a pushfit? The...
Hi all,
We've bought a property that has a Worcester Greenstar 37CDi boiler installed, with an old British Gas RS2 Thermostat linked to it. I'm not clued up on boilers in any way, though I'm quite handy with mechanics and always like to learn how things work.
The problem: The internal Bosch...
Hi
We urgently need to get our h/w cylinder replaced because it's leaking. Our current system is oil boiler feeding underfloor downstairs, radiators upstairs and an unvented hot water cylinder for hot water. We are thinking of moving to a heat pump at some point but aren't ready to do this. My...
Hi,
I’m looking to find a replacement Collector circuit pump for a ground source heat pump. This is the pump on the brine circuit. The pump I have is no longer supported by the manufacture.
It’s a Wilo TOP-S25/7.5
Any recommendations would be very welcome.
My Vaillant boiler now only fires up for around 30 secs then goes off. The egg timer symbol then appears and flashes for several minutes. After that it fires up again and heats the rads. Would be grateful if anyone could suggest why this is happening. Thanks.
Hi, we have a back combi heater. Whenever the heating comes on it seems to lose pressure within a few hours and I have to refill each morning. The boiler seems to function well, and the pressure only drops with the heating and not the water being on. Ie it started last winter and was then...
Got back from a week visiting family over Xmas and our boiler has now started making banging and grinding noises.
It’s a British Gas 330 which is a Glow Worm boiler.
This valve is fitted to the lower heating coil of the hot water cylinder Can anyone say what is the point of it I have been told its a thermostatic valve to control hot water temp so would have thought it may be in the wrong position ?Any explanations welcome
I got my regular annual boiler service for my Vaillant ecoTek 930 about a month ago, and the engineer identified that the AAV was leaking, so he closed it. This is a tenanted property and it's not straightforward to get access to it.
How risky is it to / how long can I leave the AAV closed...
