Rated 5 out of 5 by cylinder well made Does what it suppose to do no faults found very pleased 2 Oct 2015
Rated 5 out of 5 by Indirect cylinder Decent cylinder at a competitive price. 1 inch female iron on cold feed and top connection. 1inch male iron on cylinder unions on flow and return. No separate connection for shower or extra feed. Decent. 4 Jul 2015
Rated 5 out of 5 good value cylinder,. well made, straight swap for a 30 year old cylinder, always in stock at our local branch :) never had a problem with these and very competitive in price too. 31 May 2015
Rated 4 out of 5 by Indirect Cylinder Cylinder is of decent quality. The one I received was supplied with the draw off and cold inlet connections being 1" female threads, and with the Flow and Return being 1" male threads. Screwfix could add this to the description to make things a little easier when it comes to knowing what fittings you might need. It is very well packaged so you can't see it without opening the box. Also it's worth noting that it's not supplied with an immersion heater or a plug to blank it off, so that will also need to be ordered separately. For the DIYers... If you are connecting to 22mm pipes then you'll need 2 x catalogue number 61955 and 2 catalogue number 50777, or equivalent. If you are not using an immersion heater you will need a plug, catalogue number 51855. I'd advise against using jointing compound on the threads and instead use ptfe tape as the threads are cut a little generously and the tape is needed to gain a good seal. Jointing compound / paste is not rigid enough to take up the spaces on the threads, especially on the female connections. 20 May 2015
