"Recently changed out old copper cylinder for a 1200 x 450 S/S. Well worth it, much faster recovery time and minimal heat loss throughout the day so much less frequent boiler cycling. Height measurement slightly less than the 1200mm quoted but not a problem, plus the pre-installed 22mm connectors save on extra plumbing. Also has additional take-off point for direct feed to shower. Seems well made and was available next day."
"Speedy delivery. Good price. Manufacturer's help line was very good. Bought to replace an old leaking cylinder. There was excess foam on each of the connection points which must be carefully removed. Then flush it out to get rid of any bits of foam inside before final fitting. If your old cylinder is really old, you may find the new connections don't line up with your pipework, despite being supposedly made to the same standard. I think this is due to whether the 'standard' includes or excludes the foam at the base of the cylinder. After altering my pipe work, it's now installed and working fine. The foam is about twice as thick as that on the old one and so will be more efficient. Reliability average because it's too early to know."
