Megaflo unvented hot water cylinders are a leading product in the hot water market. They are often a first choice when thinking about mains pressure hot water cylinders. There are a few points to consider in an honest review of these products. Megaflo was the first big selling new style unvented hot water cylinder using high grade stainless steel and an internal air gap. The air gap method can be useful in not having to install an external expansion vessel which will give a small installation time saving. Megaflo do also produce high quality unvented cylinders which cannot be argued with. You do have to pay a hefty price tag though even when buying Megaflo at a discounted price from MDS sales. Is it worth the money? Well think about Hoover, everyone uses the brand name but how many people buy a Hoover? There certainly are a lot of vacuum cleaners sold though. The same argument goes for the hot water tank market as well. Our leading seller for a high quality stainless steel unvented mains pressure hot water cylinder is a Telford Tempest. Built to exacting standards these cylinders will give the same performance and last just as long but will cost you 50-70% less to purchase. Telford with its external expansion vessel will require another half hour or so to install which is the only negative, Telford produce their cylinders in the U.K and also manufacture the widest possible range of sizes and types of mains fed hot water tanks and cylinders.
