Rated 5 out of 5 by Indirect cylinder A very good product and fast next day delivery and a very helpfully team at screwfix 22 Mar 2016
Rated 5 out of 5 by Great cylinder Good product with prompt next day delivery, Easy to fit with small adjustments to the pipe work. Too early to comment on reliability, but it has a 10 year warranty. Good value for money. 7 Jan 2015
Rated 4 out of 5 by Things to know I replaced my old copper tank with this unit and thought i would share my experiences. 1/Always wash out the tank as there WILL be bits of foam inside. Mine had lots and you don't want these in your pipes! 2/This tank has 2 side and 1 top hot water connections (total 3, plus the heater exchange coil connections) so if you might need a blanking connection. The description on here and the manufactures site doesn't show you this. 3/ You will need a Incoloy Immersion Heater. 4/ The connection positions WILL be in a different position to your old tank, so don't expect a quick swap out. The British Standards are meant to make easy but it wasn't and all pipes needed adjustment. Cant comment on reliability...yet. we will see in 10 years time :-) Hopefully that will help you! 18 Jan 2014
Rated 4 out of 5 by Good tank but take care! This is a good tank, well made and initial impressions are that it's very efficient. However I had a couple of issues with it. Firstly when I looked inside the tank before fitting there were lots of large bits of insulation in the bottom - this was a real pain to get out, but if I hadn't have checked it would have been even worse as this stuff would have floated and blocked the hot water system - imagine how many extra hours that might have taken to fix! Secondly the immersion flange is weird with hardly any flat sealing surface and almost certainly would not seal with the usual washer, so you need to resort to lots of ptfe! Having the 22mm compression fittings is a real benefit - excellent in a restricted space 19 Dec 2013

Answer: 
Thank you for contacting us. The 815 x 450mm Stainless Steel cylinder has been designed to be as close to its copper counterparts as possible, however because so many designs of copper cylinders exist it is impossible to say that alteration wont be necessary, however in many cases alteration is kept to a minimum.
