Hot Water Cylinder Jacket 18" x 48" x 80mm x 1219mm is rated 4.1 out of 5 by 36.
Rated 4 out of 5 by from Decent Jacket Low cost and functional. Easy to fit and makes a heck of a difference on my already foamed water tank. The instructions say to overlap the panels at the top as they are square to give extra insulation. I did mine differently to the suggested technique by fixing the left and right panels first then the front and back panels with an additional tape. Much neater and less 'flappy' bits.

Rated 5 out of 5 by from Can't grumble for the price! I didn't expected much to be honest for the price but after the initial survey said we'd benefit from a thicker hot water jacket I thought I'd give this ago before winter kicks in. The one I received the outer bag had been opened and ripped but tried not let that detract from its functionality. The eyelets aren't great but do keep it in place for the time needed to fit it. After an hr of cursing and hugging the tank due to the position its in and making sure they overlapped properly its made our hot water hotter for longer well into the next morning. The airing cupboard isn't half as warm either. Our tank already had a thinner purpose sized jacket so I've in effect doubled its effectiveness. If it saves me 9 quid in energy it will have been well worth the hr lost :)

Rated 2 out of 5 by from Cylinder jacket- wrong size Perfectly acceptable product but the size was only 42" long, not 48" as advertised. Screwfix don't sell the 48" one as I discovered when I rang head office. I was offered a refund, and an apology

Rated 1 out of 5 by from Listing still states wrong siz Product is actually 42*18" despite the advert stating 48*18. Very annoying having to return it as a consequence.

Rated 5 out of 5 by from Easy to fit,does what it says. I was replacing the immersion heater so decided to replace the 25 year old insulating jacket. This was easy to fit with simple to understand instructions and took about 15 minutes - fiddling it around pipes in a confined space. The result is far less heat loss - judging by the surrounding temperature and a neat and tidy job.

Rated 5 out of 5 by from Made our hot water hotter This tank jacket is great, keeps the heat in and keeps the water in the tank warmer. As a result the room that the hot water tank is in is now much cooler, thanks ScrewFix.
