Back boiler replacement: also replace cylinder?

asteroids over berlin

Hi

Due to a bad BER rating, we got the house pumped with beading and the attic insulated.
However, the direction the front of the house faces appears to be in line with wind direction in winter and so the vents on the walls let the cold in like there is no tomorrow.

We have a Baxi back boiler circa 2002 and were advised to get it replaced with a modern wall boiler and so we could block up the vents as well as in the long run, energy costs will be down etc etc

We were also advised to replace the cylinder (very minor leak - if any) in the hot press.
Any opinions on should we do so - or is it normal procedure to change the cylinder, also the guy mentioned separating the heating water supply so we could turn off all rads with one valve?

I know this is a bit vague - but any opinions appreciated.

A modern system is zoned to allow heating of the hot water and rads separately often two zones for rads upstairs and downstairs. Each zone should have separate time and temperature control so that if the timer isn't calling for heat in the zone, it isn't heated and if the timer is calling for heat as soon a it warms up the thermostat turns off the heat or it doesn't come on if the thermostat is already satisfied. Each timer powers a thermostat which powers a motorised valve to open, when it's open a switch inside powers the boiler. So there will be days when you have the heating set to come on and the boiler won't even turn on also from summer to winter you won't have to even adjust the heating settings (well maby when the clocks go back and forward).
With thermostatic rad valves this is a system that saves on heating cost.

thanks for the info. But I wouldn't necerssarily would have to change the cylinder for this?
Also we were quoted 2800 for an ideal logic system 30 15kw - just for the boiler installation, this comes across pretty steep as from what I read, it is a low end boiler

I'm an oil man so I couldn't be sure about the pricing but it seems heigh for just a boiler and cylinder. Cylinder replacement is up to you. If it's leaking I'd advise replacement. If it's not and your happy with it then leave it.

Thank you

Cylinders have a limited life span, they can last for a very ling time if the water in the area is kind to them but in some areas they need regular replacement. So if your cylinder is leaking now seems a very good time to replace it.
