How many cylinders in UK left?

[Goldspoon]

Two questions:

1. What sort of percentage of properties in the UK have a cylinder/f&e based system (rather than combi or unvented)? Anybody know approx... or just an idea from your experience...?

 

[Breesey]

I would have thought that it was still the majority.

 

[JohnD]

I've got one and i think it's wonderful.

There are about 17 M homes.

Boilers last 10 years.

Last 10 years 56% of boilers fitted have been combis.

Its anybodies guess but I would suggest about 50-60% are combis by now.

The manufacturers probably have a better idea but keep it secret!

read a report about the coming change in the wobble number of gas, in the report it said something like 60% are combi now. so agile guess is about right

Tony, I have 1400 customers who's boilers I service on an annual basis.

over 500 are over 10 years old.
145 are over 20 tears old
26 are over 30 tears old
7 are older than that, with my grandads bbu being in its 41st year.

I have less than 7% combi boilers.

Oops! Well the second question was going to wonder at how many cylinders had the older more unsafe immersion heaters with no safety cut off...?

Q2 , nearly all of them. Many are only there as backup so almost never get used.

On what do you base this article of faith?

My mothers house has got a direct cylinder heated by an eastham maxol 12c gas bf heater. In 30 years it has only needed a new gas valve assy once. Most economical water heater and hot water cylinder supply you can get. Never any problems

I've got eight in the shed, and they're going to the scrappy tomorrow

Liked the weigh in myself after a combi conversion. Strange how some cylinders weighed little and only got £25 a go. And others weighed a lot heavier and got £40 a go. Different graded i suppose. Theres no conning a scrap man, they are nearly always big egors and intelligently numb on the side of menace
