Hot Water Cylinder Jacket 18" x 48" x 80mm x 1219mm is rated 4.0 out of 5 by 43.
Rated 4 out of 5 by from Best value for money My hot water cylinder was not lagged. My tank cupboard was like a Sauna. I fitted the jacket and the cupboard temperature dropped dramatically by 15'C. The Jacket was easy to fit and great value. Given the nature of this item I have no doubt about its durability. FEATURES - It helps retain the heat in the hot water cylinder where it should be and I expect to make a savings on my energy bill. Will not take long to recoup the cost. Highly recommend.

Rated 3 out of 5 by from Cheap but tapes let it down Sure enough this is quite effective..WHEN you've been able to fit gently without breaking the flimsey securing tapes. I would happily spend another pound or two if the fixings were made stronger.

Rated 4 out of 5 by from Good Value for this jacket Purchased and pleased with price and fit. I did notice the rivet eyes on a couple of the panels had not held, these rivets are for gathering the panels together around the top of the cylinder. Other than that four panels fitted cylinder well.

Rated 4 out of 5 by from Energy efficient After looking for a cylinder jacket online screwfix was the best value, the same jacket is available on Amazon for 30 pounds. Easy to install and we have noticed the bedroom is much cooler now so it's doing it's job, the real test will be when we get the electric bill after winter. So far so good.

Rated 1 out of 5 by from Size is misleading Although listed as 48" /1220mm in the title, this is actually for a 42"tank (as it says deep in the product info) and I was supplied with a 42" jacket, not a48"one as advertised. So now I have traipseback to screwfix for my money back. Screwfix , this is doubly misleading since 48"is the next std tank size after 42". Thanks!

Rated 4 out of 5 by from Great value This cylinder jacket is great value considering it's half the price charged by the other big DIY chain. I had some difficulty fitting it but that was more due to the awkward location of my hot water tank than with the product. Very good value.
