Plumbing, Heating and Gas Engineers in Guildford | Vented vs Unvented Hot Water Cylinders

Based in Kingston-upon-Thames and Shere, Surrey, Surrey Gas & Services Ltd carries out a range of services in the local region, including boiler installations, central heating repairs, boiler servicing, bathroom installations, boiler repairs and general plumbing and gas works. However, what you may not know about us is that we also specialise in bespoke unvented hot water cylinders.

 

If you live in the Guildford area, we can manufacture a bespoke hot water tank to your exact specifications and requirements. Offering hot water storage solutions in a range of shapes and sizes, which can accommodate a variety of fuel sources, enables us to optimise the connections and minimise the necessary pipework.

 

If you are looking to make changes to your hot water system, this page details the differences between vented and unvented hot water cylinders, to help you make the right choice for your property.

 

Unvented Hot Water Cylinder

 

This is a pressurised system, connected directly to the cold mains water feed. Whether heating water directly, through an immersion heater, or indirectly, via your existing central heating system, unvented cylinders provide hot water at mains pressure. This is a great way to increase the water pressure of your shower without opting for a new boiler installation or power shower.

 

As unvented cylinders do not require a cold water storage tank, this frees up space in the loft of your home in Guildford and means that our gas engineers have greater freedom regarding where to install it.

 

When installing an unvented hot water cylinder, we fit expansion vessels which enable the water in the system to expand as it becomes hot. We also install the accompanying safety mechanisms, such as twin thermostats and pressure relief valves.

 

Just as with boiler repairs, central heating repairs and boiler servicing, it is essential that only qualified and accredited plumbing, heating and gas engineers like us perform hot water cylinder installations around Guildford.

Vented Hot Water Cylinder

 

This is a much more traditional option, which involves having a cold water storage tank in the loft. A gravity system supplies water from the tank to the cylinder, instead of coming from the mains. Some homeowners in Guildford, therefore, experience a lower water pressure than those with unvented cylinders.

 

Either your current central heating boiler or the immersion heats up the cold water, and as the storage tank enables trapped air to escape and allows for the expansion of water when heated, there is no need for our gas engineers to install expansion vessels.

 

Due to their more rudimentary construction and the fact that they operate at a lower water pressure, vented cylinders are generally the cheaper of the two options. However, they take up much more space than unvented cylinders.

 

At Surrey Gas & Services Ltd, we can fit unvented hot water cylinders as part of a new boiler installation, limiting the amount of disruption to your household, while boosting the heating and hot water systems of your home in Guildford all at once.

 

Our gas engineers recommend regular servicing on unvented hot water cylinders, just as we suggest annual boiler servicing to avoid the cost of preventable boiler repairs.

 

We may also perform maintenance work on hot water cylinders during central heating repairs in the Surrey region.
