Boiler modulating - best preformance?

But, lawdie, 21oC? Tsk...

Oh dear. A simple post, with honest useful information, requesting similar help and now I get criticism.

So you know all about my living circumstances? Why I would want or need 21degrees of heat in my home? So I have now to justify that?

 Really?

How much more efficient over standard boiler is one with load control and weather comp?

I was teasing, John. In earnest. 

You are absolutely entitled to have your heating on at whatever level you - or your wife - like. And you don't need to justify it. 

I'll try and justify my tease-i-e, tho'. There is a bit of a crisis going on, where it's barely an exaggeration to say that decency, civility, and democracy is under threat. And because we've seen the true mettle of the British electorate over the past few years, I would hazard their resolve and commitment to Ukraine (and the West, should they fail) would soon crack should energy prices continue to soar, power cuts occur, or taxes rise excessively. And if everyone continued to keep their homes at 21oC, that's what's likely to happen.

Buy her a few new jumpers and tell her it's to help save the planet. Heated throws are cosy for evenings in front of the TV. Heat the human is the new way.

We are lucky enough to be able to afford heating but keep to a 17.5C max as we also care how it affects others.

Elderly and those with medical conditions will suffer if too cold. Extra layers and heated throws are not always the answer.

Just accept that some people need to keep warm. My wife has chronic pain and other health issues that are aggravated by being too cold - but obviously you are right, I should make her suffer in pain to fit your self righteous agenda.

Our energy usage is still a fraction of most houses in the UK - it's not about being miserable for the sake of it (which seems to be the main British past time at the moment), it's about heating to the level that's needed in the most effective way. We've invested in the right things over the years so that we can be comfortable.

Assuming that it is a condensing boiler the likes of Viessmann will say it can be up to ~15% with weather compensation potentially more efficient than load compensation.
It does depend though upon how you are currently running your boiler e.g. if you are already manually adjusting boiler flow temperature. then doing so automatically will still improve but by less than if you were normally just sticking your boiler flow temp to a certain temp & leaving it on that at all times.

This is an interesting article https://www.heatsy.co.uk/blog/outdoor-weather-compensation-vs-load-compensation-vs-tpi/

I don't think Alnat has suggested that there aren't folk who need to keep warm - of course there will be, and that's fine. And everyone else is also free to heat their homes as far as their purse and conscience will take them.

I would just ask where would we currently be if no-one changed their heating habits? 

I know it's not fair; I doubt if many of those who can easily afford the current energy prices will touch their room 'stats - sacrifice is not for them -  and many of these are likely to be the folks 'running' the country. But the more gas we all consume, the higher the prices will be, the harder it'll be for many others to keep warm, the greater the ultimate tax burden, the greater the actual risk from outages, the greater the risk of loss of life.

As far as my 'tsk' response to the OP, yes, sanctimonious, no question. But I don't think it was completely unacceptable given that the OP came on here asking for advice on improving the efficiency of his boiler, telling us they keep their hallway at 21o, and it's because 'his wife feels the cold more than he does'. Based on that, the obvious answer is 'turn it down a tad - that'll give you the single greatest savings'.

(I am not going to suggest or claim that the reason we've turned the temp down to an average 18o is for the sake of the country - it isn't, it's to save money, commensurate with finding that temp quite acceptable. It helps to also understand it's of communal benefit, tho', - a win-win - and if the opposite were true - that it harmed the country - we would try not to do it.)
