Rated 3 out of 5 by from Made in England Not fitted yet but opened up to ensure all components were there, which they were. To be honest I don't have much luck buying British made products and I'm concerned about the quality of the item as the first thing I noticed was the outlet connector producing from the top at a strange angle, not perpendicular to the top of the tank. Lucky I own a pipe bender.

Rated 5 out of 5 by from Easy to fit, great insulation! Bought 2 of these for hostel on Isle Of Skye for running Ladies and Gents showers, easy to fit with most fitting in the box. Had it running of a 250L cold water storage tank through a 3.6bar pump to a TMV and then onto push button shower. Switched on heating elements, 2 hours later hot water you could shower from, switched off after test, nine hours later still hot water for showers. Fab. Fully recommended.

Rated 5 out of 5 by from More than you think Doe's exactly what it says on the tin and more. The kit comes with an expansion vessel, two safety valves, filter and is preloaded with heating elements and stats. Plus all connections are 22mm (simples)
