Best way is to run a new cold water pipe from the header tank to the cold side of the mixer.

The flue gas temp needs to be high enough to prevent condensation from running down into the boiler but not so high it wastes fuel. It will be set during boiler annual service and is not something a home owner should mess with.

It costs a bit more because you don't recover the latent heat that goes up the chimney but you benefit from a more responsive system.

To quickly heat the house from cold I have the flow temp set to it's max of around 85 deg C although the downside of that is that the condensing capability of the boiler becomes ineffective.

Even with a condensing boiler there is still a lot of water in the plume and because the venting exhaust gas is at a lower temperature than a non condensing boiler you will see a lot of vapour and drips around the outlet.

Not heard of a multi kill trap. The problem you have if you do not check traps regularly is flies. Also from a humane point of view you need to check daily because mice are so very fast that sometimes spring traps just catches them by the leg.

I live in an older house in the countryside - impossible to keep rodents out - just too many tiny gaps for them to squeeze through. I have tried all the 'fixes' and the only thing that works for me is spring loaded snap traps and plenty of them. You bait the traps with peanut butter and check...

I have seen pipes where they are almost completely blocked apart from a small gap.

In the meantime best leave the heating switched off for half an hour or so after future oil deliveries just in case.

Looking at those photos it might be worth checking your tank for water ingress.

Is the tank outlet higher or lower than the inlet to the pump.

You won't keep them out. They can get in through the tiniest gap so small that you can hardly even see it. I've tried most methods of eradication and the only thing that works is spring loaded snap traps. Put plenty of them around baited with peanut butter and check them every day. After a while...

There are stripped down versions of Windows 11 available. I installed one on my partners 15 year old Toshiba laptop that had been running Windows 7. That was a couple of years ago and it is working just fine.

So DIYer turns off water at mains - tries to graunch off immersion with improvised tool and it doesn't move. Next uses extension bar on tool - puts boot against opposite wall of airing cupboard and heaves. Tank creases and splits at boss boss joint. Jet of water sprays out of split and keeps...

Worse thing you can do is apply torque to an immersion nut. Pretty much guaranteed to wreck the tank.
