The facts are there staring you in the face and you still deny it. Who said anything about it not having to be paid back instantly. It’s going to be a drain on the resources of this country for decades to come. Much like this current obsession with net zero, only on an even greater scale. Reality deniers are worse even than climate deniers. At least some on here that argue for it accept that we won’t be able to always heat our home or go on holiday anymore.

You said ‘about what covid cost us’. If you seriously think covid only cost £40B then I can see why you swallow some of the other nonsense pushed out by various politicians. Here it is from the horses mouth. https://commonslibrary.parliament.uk/research-briefings/cbp-9309/#:~:text=Current estimates of the total,the pandemic for that year. ’Current estimates of the total cost of government Covid-19 measures range from about £310 billion to £410 billion.’

Covid definitely didn’t only cost £40B. Missing at least a zero on that. Makes me question your other figures without even checking. All those problems, and yet France did it half a century ago, and still have cheaper electricity than us with all our wind power. Not forgetting the fact theirs works 24/7/365

Start with the simplest/cheapest fixes and go from there. Raise vent pipework Check H pipework Consider blockages elsewhere - heat exchanger potentially If raising the vent pipework cures the issue, happy days. I still suspect there is a partial blockage somewhere, but it might be years before it causes a further problem, if ever.

Letting foreign owned corporations take the pee out of us can’t really be counted can it. The technology for nuclear isn’t anything ground breaking. The French have powered most of their country on it for decades. We could easily reliably power our whole grid from it if the will was there. Your preferred plan involves technology that cannot power the grid reliably and puts us back to the dark ages to boot. You’re implying that nuclear isn’t a viable option. Extraordinary!

I’m not sure how forcibly putting people into a state of poverty, or even just worsening their living standards is caring. But anyway off the top of my head. 1. Mandate PV on all new build / large extension roofs 2. Invest heavily in nuclear 3. Improve insulation and ventilation requirements for new build and extension. 4. Take into account all emissions from mining/manufacture/shipping/disposal etc when deciding on carbon emission figures of a product. If a product is made elsewhere those emissions must be taken into account. 5. Invest in wind to the point where it can be properly utilised. No point running wind and nuclear concurrently for when the wind doesn’t blow. 6. Scrap the ban on petrol/diesel vehicles. It won’t work. Too soon. 7. Those who make the rules to lead by example and any breach to be punished more harshly than the general public. 8. More emphasis on clean and healthy air/water/food supply than C02 9. Plan for temperature/sea level rise and invest in what’s needed to cope with it. If the Maldives can keep expanding their land area when they were meant to be underwater years ago then it must be possible. 10. End political interference by big corporations/‘philanthropists’. No donations over £200 allowed. 11. Stop wasting taxpayers money on vanity projects and other nonsense that doesn’t benefit the taxpayer Drifting slightly off topic but I could go on. Basically do the best we can with the technology we have and invest in new technology as much as possible. It won’t happen though - too much money to be made.

It won’t be accepted. Get the pitchforks ready! Let’s impoverish our population - with all the death and destruction and social breakdown that would go with it, all to stop the emission of a gas that has no effect on human health, but ‘may’ cause global temperatures to rise slightly (which by the way we could adapt to life with). I can’t believe how so many people are happy to go along with this nonsense.

Gas prices have come down as the Ukraine war has progressed. Yet electricity prices have not followed to the same extent. If it was gas causing the price to stay higher this wouldn’t be the case.

So gas is barely more expensive than 8 years ago, yet electricity is fairly significantly higher, and was so before Ukraine war. Wonder why on earth that could be.

Source for that?! The only remotely viable way is nuclear, but for some reason those in charge would rather pursue their visions of utopia.

Possibly. But nobody has a crystal ball and experts/general consensus been completely wrong time and time again throughout history. The problem is that the choice is between carrying on as we are and doing our best to reduce emissions where possible, or net zero and near complete deindustrialisation. Renewables/air travel/heating our homes/working more than walking distance from our houses/car ownership including EV. None of them are compatible with net zero, unless we agree that offshoring our emissions doesn’t count - which is of course ludicrous. Whether or not you agree with the idea of man made climate change - I’m still somewhat on the fence - the ‘solutions’ are nonsense spun up by the very few people who will benefit from them.

Agree with that, but how many can you do that with anyway? Hager. Starbreaker. Some of the brands under the Schneider umbrella. I’m struggling after that.

Nothing wrong with those mods imo. Fusebox is good stuff and a decent price. I use loads of it and have it in my own house. Money no object, Crabtree starbreaker is the best consumer unit (domestic) imo. Hager is also decent, but the slant on the breakers is no better than Fusebox (ie. Acceptable, but not perfect). Hager have just massively reduced RCBO prices, so obviously feeling the presence of Fusebox! Goes to show how much they were making before…

Nonsense. Inflation is 35% over the last 10 years. As per the Bank of England website. Energy price inflation is at least 3 times that. It’s the road to ruin. As someone else just said, cheap and reliable energy is the main reason living standards have rapidly improved over the past 200 years. Without it - a catastrophe that would make WW2 look like child’s play. As for the last comment 🙄

So there we have it. The thin end of the wedge as many of us predicted. Lucky I can afford PV and an inverter that accepts a generator input. Not sure how everyone firing up their own generators helps with reducing C02 though? Mad max here we come.

Agree almost entirely with @ProDave If carbon dioxide is really the biggest problem that we face and worth spending enormous amounts of money on (not inequality, lower living standards, crumbling public services and infrastructure, inflation, social cohesion etc etc) then why are we not investing heavily in nuclear. We all know that renewables can’t operate reliably in isolation. Also worth noting that in the last decade my electricity cost per unit has gone up by over 100%, with the standing charge going up by even more - far above the rate of inflation. I thought renewables were meant to be cheaper?!! No doubt some will blame Ukraine war for this as the cost of gas has risen, but we have mountains of gas of our own that we for some unknown reason refuse to extract. Far better for the planet to import LNG from Qatar and the US - make it make sense.

At a guess, when you get a restriction, the pressure created by the pump causes the water to take the path of least resistance - up the Vent pipe.

Heat exchanger wasn’t totally blocked on my boiler either. Just about heated the cylinder and got the rads hot for 20 mins or so, then went lukewarm. The USP3 is a very common pump. It won’t be the sole cause of pumping over on a system configuration and that has never previously pumped over imo. I think it’s pretty well nailed on that there’s some sort of obstruction/blockage on the primary circuit. All only in my opinion obviously.

There’s no doubt it’s a slight risk. The part could be damaged, perhaps even by plumber upon fitting - who will blame the part probably. However, if you can find someone sensible to fit it, it’s a risk worth taking imo. Those boilers are fairly bulletproof otherwise in my experience (had one in my old house for 9 years - was 14 years old in total when I sold - zero problems) and your only other option is new boiler if the heat exchanger is indeed blocked.

This is still sounding so much like my situation from a few years back. I also changed the pump as a first move. I also then cut the H section out and found it clear. I removed the mid position valve and found that clear. I then decided it was very likely the heat exchanger in the boiler as it was unlikely to be anything else stopping good circulation around the primary circuit. Also open vented systems suffer with sludge build up, and I had no magnaclean. It’s interesting that my boiler is also the same as yours. You could just replace everything to fix as plumber 3 wants, but seems wrong to me. If I was you then I’d check the ‘H’ section of pipework and if it’s clear I’d be getting the same refurbed heat exchanger that has cured my problem. Assuming you can find a plumber willing to spend a couple of hours fitting it for you that is. I twisted a mates arm (quite hard it must be said!) £150 for him and £80 for the heat exchanger- which according to him looked new.

Threatening it yes, but dates in the near future? Not that I know of. 30th June 2025 is apparently the date. To my knowledge they’ve not given a firm date before, that has then passed with the service still operational. We’ll see I suppose.

Haha LW only!

Radio 4 (which the teleswitch signal runs from) due to be switched off in June, so not too long.

Am I correct in thinking that pump over isn’t the only problem (symptom) here? The original (and also current) problem is lack of circulation and radiators not getting hot enough. Is that still the case?

I can’t see a low loss header in any of the pictures? I’m no plumber (electrician), but I’ve wired hundreds of boiler systems and investigated a lot of faults - although mostly electrical. Seen tens of UPS3 pumps on standard Y/S plan vented systems and never heard of one being the sole cause of pumping over. I pass the plumbing faults over to the plumbers I work alongside, but usually like to find out the cause once they’ve solved, for future reference. Pumping over very often seems to be a blockage and poor circulation. Blocked heat exchanger in boiler/blocked pipework usually where the close coupled tees where F&V pipes are, especially if this is one of those Myson aerjec things. Hopefully a plumber will see this and post soon
