Happy New Year.
Okay, maybe the subject is a little dramatic, but hopefully I've got your attention for a few minutes 😀
After a recent upgrade of my CH system, which included a LLH and a new circulation pump, my trusty old Vaillant ecoTEC 637 Plus system boiler seems to be spending a lot of...
Just had a Grundfos UPS3 installed, replacing old UPS.
Working well, but I wish to understand a little bit more about the Proportional Pressure (PP) mode
If I run it in Constant Curve (or Speed) mode, CH & HW are fine, pump running.
If I go to PP mode CH & HW outputs are still fine.
BUT, the...
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...
Hi. I have a Salus RT510TX thermostat and the batteries in the transmitter unit ran out. (After it went dark I kept forgetting to go get some alkaline batteries)
Now with new batteries it won’t power up at all. Any ideas please? No combination of buttons seems to reset it??
The receiver seems...
Hi folks be glad of some help with this as its puzzling me.🤔
I have an Alpha 2 15-60-130 pump serving 12 Rads with thermo valves and Hot Water cylinder. The boiler is an Alpha CD18R
Since I had another rad installed downstairs I've noticed the heating pump has been noisier than usual ie...
Hi
for a few reasons (problem with hot water, possible smart heating installation), I familiarised myself with my heating system and wiring. Looks like a standard S-Plan with magnetic valves for hot water, central heating and UFH. Valves are controlled by normal standard backplate programmer...
I am a retired Chartered Electrical Engineer and am looking for information about the necessary conditions for gravity primary circulation in a 28mm domestic indirect vented hot water circuit.
Until recently I have fitted Hercal cylinders in my house and they always worked without any...
BOXT Boilers and Boiler Installations - Are you a BOXT Installer?
Seen an advert on TV for a BOXT Boiler. Black friday deal. Wondering if we have any BOXT installers on here and whether they're doing alright with them?

Hi folks, just a regular member of the public here, learning all he can before having a new combi-boiler and radiators installed in my old victorian flat. For years I've just had some fan heaters! But now it's time to upgrade.
I'm fairly techie, but I can't see why your would range-rate a...
Hello
My Greenstar CDi boiler goes into Siphon Fill mode multiple times a day for 15 minutes at a time - this means that there is a 15 min lag between the thermostat clicking on and the boiler leaving the siphon fill mode and kicking in and heat returning to the radiators.
Im looking for a...
Hello,
Around 2 years ago we had a very old, leaky Baxi combi replaced with a newer Baxi.
For background I live in a 3 storey terrace. First floor has 3 rads, second floor has 4 rads and third floor has 2 rads.
We noticed problems with noise and air in the system. One of the rads in the loft...
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?
Recent install Firebird 26kw Condensing boiler. Space heat only. Installed as replacement boiler in well insulated 80s renovated home. (Silver bead wall cavities, triple glazing 0.6 centre pane U value, 450mm rockwool in loft) This house is now split into 2no zones. Downstairs and Upstairs...
Hello everyone,
I have a problem, to which there is probably a simple solution but I can't see the wood for the trees.
I swapped out an old Grundfos pump for the new one. Gone is the lovely old silver button on the front where you can bleed the pump and now we have more bells and whistles. But...
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...
Wondering if there are plumbing gurus here who can suggest what could be the issue .Recently changed to gas heating and have a viessmann vitoden 100 , 26 kw condensing boiler .The old oil boiler was a firebird 26 Kw and I have almost already started missing it .
The house is well insulated and...
Hi,
I have noticed my boiler Viessmann Vitodens 100-W(B1HC-26) makes a series of short cycling before starting to heat. Boiler is controlled by Baxi uSense room thermostat connected via Opentherm. I installed some monitoring equipment to get the better understanding of the problem. Bellow is...
Hi
When the zones are near temperature (if far away it keeps boiler fully on instead) it seems that the Evohome is bringing the boiler on for 1 minute in every 10 (as some of the zones are reporting not at 0% even though the system is reporting that it is at temperature).
I believe (though not...
Hello can someone help, my boiler this morning needed topping up as it was showing no pressure and flashing radiator symbol, I've topped it back up but still have the flashing radiator symbol and won't fire up.
It's a glowworm 100e
Thanks for any advice
Pete
Hi gents
You helped me massively before so I thought I'll give it another go as is Saturday evening and I'm totally stuffed with my Honeywell programmer. The problem is it doesn't stay in just click on and off. Lights off and back on when I try to set it to water heating or central heating...
