TLDR OK, this is not so dozy a question - and the background is below for people who want to know why I am asking this, but bottom line: What is the technical reason for anti-cycling lockouts? Does constant firing use too much gas, wear something out - what? Put it another way: If there was...

Great minds think alike! I did consider this - but rejected it for two reasons: 1. The existing skylight is in a roof with an adjacent wall (side of the house) so looking up through a pyramid lantern, I would see a big wall, whereas, the current rooflight, because it is almost flat, just gives...

A BIG thanks to you all for your input - some really useful (and sanity reinforcing) comments here. To be clear, if I could have found someone to do the replacement sealed unit I would. (I was going to specialists - not the usual white PVC window installers). You are right, it is Planitherm...

That's more like it Harry - I like your "pioneering" spirit! I have been wondering... instead of dry air (where am I going to get any of that in this country?..) about some sort of inert gas - and given that it was filled with Argon in the first place, I have just rather surprised myself by...

Thank you @crank39 and @mrrusty ! I guess the reason for the sizes, is that whatever individual panes are used, it all needs to add up to 28.8 - so as to fit in the upstand and teh extruded aluminium (I guess) edge that runs around it. BUT when you say "Fitted" - that's the challenge.. I am...

Unfortunately, my warranty (for the sealed unit) wasn't insurance backed, so if I do pay to fix the problem (basically, by buying a replacement from the new company owners) I become an unsecured creditor - and I can't imagine that will go well.. So yes, my plan was to rinse the inside of the...

Stick with me on this - there is a method in my madness.. I have a 1000 X 1500 Sunsquare skylight (https://www.sunsquare.co.uk/product/skyview-rooflight/) The sealed unit in it is a bit special: - 6mm toughened soft coat low E outer pane. - 14mm Argon filled silicone sealed cavity with a...

Ah, I see what you are saying - but that's not me saying that. it's the dude who wrote that blog LOL! I agree with your analysis though, HOWEVER, while I can't comment on the zone valve closing during anti-cycling (simply because I have never experienced that) my pump DOES stop during...

@Johntheo5 thanks so much for this! My apologies for not being sufficiently clear: If I set D2 to default time of 20, you are correct, that according to the table, with a target of 60C, actual anti-cycling time will be 6. That's what I get in any case with D2 set to 10. HOWEVER, if I set D2 to...

@Johntheo5 – my big apologies, I should have been clearer that I was the one that set these. D0: 12 – yes, 12K otherwise I find that when the burner fires, it heats up faster than it can modulate back down – so I get a burst of about 15 secs and then nothing until.. D2: 10 – because if I set...

Oh thank you so much for this! It's an EcoTec Plus 837 and yes, I have an upstairs Bathroom towel rail that is always on - even though, as you say, the zone valve is closed (only opens when the timer calls for upstairs heating in the evening. Now, there is some weirdness - which will probably...

Thanks! So what would this by-pass typically consist of? I ask, because I have all UFH on the ground floor and normal rads upstairs (on a Y Plan). This was installed by a heating engineer (not me) as part of a refurb 11 years ago - and I am not aware of any components that could be deemed to be...

Two data points that may help: 1. I have had my system in for about 10 years now - with Ground floor all UFH and upstairs normal rads. 10 years is long enough that I have been able to experiment with one winter season running 24/7 - on the grounds that once you heat up the entire mass of the...

So, I just turned the mixer up to max, and control the flow temp at the boiler. In that way, I can dial it down to 60C max, which is how I get the above manifold temps. In any case, are you sure your mixer is, well, properly mixing? Just to be on the safe side, I bought a service kit...

I have had a similar challenge to you, so here are some top tips of things I literally last changed/adjusted in Sept: 1. Boiler is Vaillant Ecotec Combi. Despite what is said here AND all the Vaillant documentation, it just doesn't work when you set target temp for Return (as opposed to flow)...
