Rated 5 out of 5 by Replacing 25 yr old cylinder Bought to replace old leaking cylinder. As noted by another reviewer the cold inlet and hot outlet are 1 inch female, I needed to buy adaptors, but only one in stock,not a common item in plumbers merchants so had to drive 10 miles to next Screwfix to find one. Also heating element inlets are in a different position to original so again some adjustment of pipework needed. Appears to be a good quality product though. 15 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
