What kind of hot water cylinder do you need?

Unvented hot water systems

An unvented hot water cylinder is a water vessel that holds heated water under pressure, releasing it when a hot water tap is opened and providing instant hot water. The name comes from the fact that the system is pressurised and so doesn’t need to vent steam or water.

Unvented systems have been fitted in homes since 1986 and are more popular than vented cylinders. The high pressure available from an unvented system means large quantities of hot water can be pumped around the system at a steady, regulated flow. Ideal for homes with multiple showers.

They tend to be more expensive to install than traditional vented systems because of the extreme pressure they operate under. Additional safety features, like relief pipework, need to be installed, they need to be fitted and maintained by specially qualified technicians with G3 qualifications.

Vented hot water systems

Popular in older homes, vented hot water systems require a cold water tank which is usually located in a loft or attic. This tank feeds cold water to a hot water cylinder. The cylinder is typically situated in an airing cupboard, with the cold water feed at the bottom of the tank. Heated water rises to the top of the reservoir where it is drawn off for feeding the heating system.

There are two methods of heating water with vented hot water systems:

  • Direct heating: Immersion heaters and/or a gas boiler is connected to the system and provides the hot water to the cylinder
  • Indirect heating: A coil within the hot water cylinder is fed via the central heating system and heats the water in the cylinder. An immersion heater is also provided so that the boiler can be switched off in the summer and the cylinder takes over providing hot water

What hot water cylinder services do we provide?


It’s essential to hire a qualified professional to install a new hot water cylinder. They operate under extreme pressure and transfer large amounts of hot water. Installation of relief pipework and other safety mechanisms must be performed by G3 certified engineers.

Our experienced engineers are fully trained and insured to install hot water cylinders for gas and oil central heating systems.

Our installation service includes any necessary adjustments or improvements to your pipework. All necessary work will be fully explained as part of a heating assessment performed before we provide a cost.

Maintenance and services

Hot water systems should be serviced annually. Unvented systems should be maintained by qualified engineers with G3 certification only. It’s critical to have the condition of relief pipework and other safety mechanisms checked each year.

We offer an annual service for your heating system that checks the condition and performance of your hot water cylinder and pipework.

This will ensure your central heating system is kept in good, safe working order and is properly maintained according to the manufacturer’s instructions.

This not only gives you the peace of mind in knowing that your system is kept in the very best condition but also ensures your insurance policy is valid.
