If it was a new build developers are not inclined to oversize radiators so if they were sized for certified output they need a 75degree C flow...
Please update as you can and may I copy the graphs please? I know I can actually but I would like your consent.
Vision Plus, 20, 25 and 30kW. The old Vision is Ali.
Thanks but I did qualify I'm biased.
I would add the same investigation that calculated the 1-2% efficiency hit if burn time exceeded 3 minutes calculated a 12% penalty if the boiler...
I work for this boiler manufacturer so know this product, you can substitute others if you wish. A 20kW Vision Plus with stainless exchanger and...
No, and being old fashioned I keep tripping myself up over this. To me a heat only boiler is just that, it contains no pump or expansion vessel or...
There is not much monetary saving in fuel as NG is so cheap but an additional benefit is range rating, limiting the maximum output so the boiler...
Yes that's what I reckon but it's the costing as well. A £1600 boiler for a 4 rad job. It's not the max but the min output needed I would think...
You're really not supposed to open the combustion box if you're not competent and further, to cure the problem you have to start stripping the...
I believe with the UK having so many high temp rad systems Ali was king. Stainless cannot live with Ali for that, ss strength is its strength and...
15 radiators is a fairly substantial system but so much depends on the total heat loss from the house (now and later) and the hot water demand. In...
Could you put some figures on that muggles to quantify sensible and efficient? A starter home might have a 5kW loss in the extreme weather and...
The boiler is then in a sealed system with no open vent at a higher pressure. A low pressure switch is not compulsory if converting an OV boiler...

Oops, I thought it was a Vision, I was helping someone on another forum and got mixed up. A 29 could be a Compact A, easiheat, Maxim or Excel,...
No plug on the Vision, you have to cut it off and wire it. About £35 from wolseley and easy to convert to OpenTherm also on video on YouTube....
No idea about that stat but look at the questions and answers. Doesn't inspire confidence.
As I work for Vokera I ought to do an advertisement although generally I think it bad form. The Vokera BeSMART control will not look as sexy as...
No need to open anything gas or combustion related, two screws outer case, one screw beneath control box lowers the box toward you. Don’t know...
