Hot Water Tanks

Unvented Hot Water Cylinder

Unvented Hot Water Tank

An unvented hot water cylinder is a high efficiency, sealed tank that is pressured by your mains water supply

Unvented cylinders deliver a powerful supply of pressurised hot water direct to your outlets, without significant loss of performance if more than one tap or shower is used simultaneously; this makes them ideally suited to modern day households with numerous bathrooms

Since they do not rely on a gravity feed, unvented cylinders can be located almost anywhere in your home

Unvented cylinders are installed in almost all new builds and can be used as direct replacements for your exisitng, traditional, gravity fed, hot water tank. If you are planning on installing a new boiler, this is the perfect time to consider upgrading your hot water tank.

Servicing your pressurised hot water tank

Vented Hot Water Cylinder

Vented Hot Water Tank

Many customers are unaware of the importance of servicing their unvented hot water cylinder on an annual basis. A regular service is necessary in order to ensure all the 'cut off' safety devices are operating correctly.

In many cases, the 25 year manufacturers warranty will be declared void if the appliance is not serviced each year.

A traditional, vented, hot water cylinder is usually located in your airing cupboard and covered with blue or green foam.

As the name suggests, these cylinders are 'vented' and deliver a gravity fed, non pressurised, supply of hot water to your taps and other outlets.

These days vented tanks are typically only installed as a 'like for like’ replacement.
