At TradePlumbing.co.uk, we supply an excellent and wide range of Hot Water Cylinders to both trade and domestic customers, through our website. Found in the vast majority of UK homes, hot water cylinders can usually be found in the airing cupboard (although not in homes with combi-boilers)

Customers who purchase their hot water cylinders from us, are either replacing an old hot water cylinder - or are purchasing one for the creation of a new hot water system. In this article, we look at a few of the different types of cylinders that we supply - with a little information about each type and its application.

Direct Cylinders

A direct hot water cylinder heats the water itself - with the use on an inbuilt immersion heater. Al direct cylinders contain at least one immersion heater, with some models having more, and therefore heating the water quicker. Put simply, cold water enters these cylinders, heated inside - leaving as hot water.

Indirect Cylinders

Indirect cylinders provide the same functionality as a Direct Cylinder, but operate in a different way. Indirect cylinders are filled with cold water, then heated inside the cylinder by a heating element which can come from either the boiler, or other sources of heat - such as solar panels. The coil inside the cylinder, is then heated and in turn heats the water within the cylinder. Hot water is then provided from the cylinder.

Vented Hot Water Cylinders

Vented cylinders rely on a separate feeder tank to supply cold water to the mains supply as well as providing the hot water supply to the cylinder. The vented cylinder then provides the hot water to the household, via a gravity fed system. These cylinders are amongst the easiest to install and maintain, but do require a cold water storage tank to work in conjunction with them.

Unvented Hot Water cylinders

Unvented Hot Water Cylinders do need a cold water storage tank, instead they are fed by the mains and as such rely on mains water pressure. Cold water enters the unvented water cylinder and is then heated and fed to the hot water taps, at mains water pressure. One of the biggest advantages of Unvented Hot Water Cylinders is that because they do not rely on gravity to provide pressure, they can be located anywhere in the property.
