Indirect Hot Water Cylinder 900 x 450 120L is rated 3.6 out of 5 by 16.
Rated 1 out of 5 by from Avoid at all cost Needed new cylinder in a hurry and paid extra for next day am delivery- arrived by 11am next morning. Fitted with few issues, other comments re excess foam true but not a problem. Minor changes to pipework require but had hot water and heating by tea time. Two days later woke to the sound of running water and found the kitchen ceiling sagging alarmingly with water dripping through it. All joints were still sound but there was a large pool of water behind the cylinder running through the floor around the emerging pipes. Stripped cylinder out and refilled outside. Water dripping through foam and when I cut this away found the soldered seam between bottom and sides had failed.

Rated 1 out of 5 by from Poor quality Lasted only 14 months before developing a leak. Manufacturer's warranty is 24 months but because it was over 12 months there was no assistance or cooperation from Toolstation. Still trying to get RM Cylinders to collect faulty cylinder and refund me.

Rated 4 out of 5 by from Needed a lot of foam trimming The cylinder is good and the foam thick and quite tough. The problem is the relief around the 5 ports was poor. Only the hot outlet was OK. Worst was the immersion heater port that was off centre and needed about 20mm cut away one side just to get a box spanner in. You need a box spanner for this cylinder. An offset spanner will not work. I must have spent a hour cutting foam back which I should not have to.

Rated 4 out of 5 by from looks presentable In the process of fitting at the moment, tell you what its like when running. The test will be after a few years though

Rated 5 out of 5 by from Easy replacement Wanted a quick replacement for a tank with a weeping leak. Guess what, your favourite diy suppliers don't stock these anymore. Toolstation provided one next day from an on line order, delivered to my home, before middayin my case, at a competitive price. Terminal connections were compatible with the original fittings so no running out for new bits. Terrific service, absolute lifesaver!

Rated 4 out of 5 by from Replacement for a 20+ year old cylinder. Good value cylinder. The cold water feed and hot water outlet are 1" BSP, which caused me a dash to the plumber's merchants but the heating coil fittings were like for like. Used plenty of PTFE tape thanks to previous reviews, the tank felt a little flimsy when tightening joints but no leaks. Pretty happy.

Rated 2 out of 5 by from copper water tank tank arrived with no bottom in the box

Rated 3 out of 5 by from Adequate, but not sure about quality and longevity Arrived promptly and well packaged. Much thinner walls and heating coil inside much smaller diameter than old cylinder, so probably longer to heat water to required temperature. Label says it will take immersion heaters up to 1000mm long but my 880mm heater would not fit. Contacted manufacturer who said it would only take one up to 700mm and suggested I bought a 27" one. They knew label was wrong but it had been like that for some time and never changed. Indifferent attitude that basically said tough. Will have to wait and see if it lasts as long as old cylinder, which was 32 years, but somehow I doubt it.
