If you already have a jacket fitted, check the thickness, it should be at least 75mm thick. If not, it's worth treating your cylinder to a new winter coat. Fitting a British Standard jacket around your cylinder will cut heat loss by up to 60% and save you around £40 a year - more than the cost of the jacket! Fitting Instructions1. An insulating jacket pack normally consists of four plastic covered panels, two securing straps and a tie cord.2. Position the panels vertically around the cylinder, with the eyelets to the top. This allows any connecting pipework pass through the gap in the panels.3. Pass the supplied cord through the eyelets and tie off so that the panels fully cover the top of the cylinder.4. Use the two straps to secure the panels in the final position.Tip: These panels insulate more efficiently if they're not compressed so don't overtighten the straps. Review: good insulation - this is a difficult size to find at this price and seems to be reasonable quality. delivery was also very fast Review: Not up to task - Don't normally write reviews but thought I would add a comment. Needed one quick to cover a tank in a shed and just saw the 4 star rating. Should have read the reviews. It makes out its for a 48 inch tank. wrong the panels maybe 48 inch but when you cover the top it does not cover 48 inch. The top rope is just two short shoe laces. the tie straps, according to the instructions there should be three of, turned out to be two lots of two. Unfortunately they are too short to fit around the 18 inch tank so you have to tie two together, still leaving you one short. the panels are not wide enough to over lap much. If I had not been so desperate to get some sort of insulation around the tank before the cold snap I would have returned it. Ended up wrapping loft insulation around where it did not touch. ## Features - Made from 80mm thick mineral fibre wool - Up to 60% heat loss saving / Save £40 every year (on average) - Jacket consists of overlapping sleeves allowing plumbing pipes to pass between sleeves - Easy to Fit / Can be applied in minutes / Two fixing straps and instructions included - Available in 30"X18", 36"X18", 42"X18" & 48"X18" sizes ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Excel | | Part Number | EC4818 | | Package Dimensions | 59.6 x 41.8 x 15.6 cm; 1.94 kg | | Manufacturer reference | EC4818 | | Size | 48" X 18" Jacket | | Material | Mineral Fibre Wool | | Item Package Quantity | 1 | | Usage | Commercial/Residential | | Batteries Required? | No | | Item Weight | 1.94 kg | ## Images ![EC4818 : Hot Water Cylinder Jacket, 48" x 18" for 45 Gallon Tank - Image 1](https://m.media-amazon.com/images/I/91doaA5ElVL.jpg) ![EC4818 : Hot Water Cylinder Jacket, 48" x 18" for 45 Gallon Tank - Image 2](https://m.media-amazon.com/images/I/812KmdG0m8L.jpg) ![EC4818 : Hot Water Cylinder Jacket, 48" x 18" for 45 Gallon Tank - Image 3](https://m.media-amazon.com/images/I/519stbNrXpL.jpg) ## Questions & Answers **Q: Has the jacket been british standard approved?** A: Is there a British standard for such things? I doubt it. This is a pretty cheap and basic design - probably largely superseded by insulated water tanks. But from my viewpoint it prevents enough heat loss to save some money, while allowing the airing cupboard to stay warm all the time. I bought it to replace one where the plastic had begun to disintegrate. I am sure this is a safe product, but if you are concerned about it conserving heat to some specified standard this is not the product for you. **Q: What is 36 gallons in litres** A: 1 gal = 4.55 litres hence 36 gals = 163.8 litres ## Customer Reviews ### ⭐⭐⭐⭐⭐ good insulation *by J***W on 20 June 2015* this is a difficult size to find at this price and seems to be reasonable quality. delivery was also very fast ### ⭐ Not up to task *by D***B on 10 November 2016* Don't normally write reviews but thought I would add a comment.

The tape itself breaks if you pull it hard to keep it tight, plus the panels dont fit very well. Disappointing really but very few other options out there. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/61002744-ec4818-hot-water-cylinder-jacket-48-x-18-for-45](https://www.desertcart.sg/products/61002744-ec4818-hot-water-cylinder-jacket-48-x-18-for-45) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-18*
