Hot Water Cylinders

Heatworks — How Water Cylinders

Hot water cylinders work in conjunction with regular and system boilers to deliver heat and hot water fast. At Heatworks, we specialise in the installation, repair and maintenance of unvented and vented cylinders. And with several years of experience in the area, you can trust us to treat your heating system as if it were our own.

Hot water cylinders store hot water for central heating systems. Heat is taken from a boiler and sent through a hot water cylinder’s heat exchange coil. This heats that water that is eventually sent to the taps and radiators in your home.

Whether you have an unvented cylinder or an immersion tank, we have the know-how and experience to install or repair your heating system quickly, accurately and tidily. We’re a team of well-mannered plumbing and heating engineers covering Dorking, Horsham, Crawley, Guildford and the surrounding areas. And thanks to our unwavering commitment to customer satisfaction, we have earned a fantastic reputation.

Unvented Cylinders

Fed directly from the water mains, an unvented cylinder delivers hot water at high pressure — perfect for showers. This popular type of hot water tank is available in a range of sizes, from 90 litres all the way up to 300 litres.

We have extensive experience in installing and maintaining unvented cylinders, so we’re able to advise our customers on issues such as low water pressure, performance and energy efficiency. We can custom-design your unvented hot water cylinder to suit your home and your family’s requirements. And we offer a long-term guarantee for your peace of mind.

Vented Cylinders

Also known as gravity-fed hot water cylinders, vented cylinders use the natural ‘pull’ of gravity to move water down a pipe and into the hot water tank. Fed by a cold water tank (usually located in the loft), vented cylinders use height to create pressure.

This type of hot water cylinder is relatively cheap and easy to install. It can provide a temporary source of water if your home suffers a sudden loss of mains water supply. However, for more reliable supplies of hot water for showers and baths, we recommend an unvented hot water cylinder.

We can increase the pressure delivered by vented cylinders with the use of booster pumps, which can significantly increase flow rates for showers.

Immersion Heaters

Although not widely used in modern central heating systems, immersion heaters are still found in hundreds of thousands of properties across the UK. Used in unvented hot water cylinders, an immersion heater sits inside the hot water tank and acts like a kettle filament.

When you’re in need of hot water in a hurry, switch on the heater’s electricity supply and the water inside the tank will heat up. If you don’t have a gas supply in your home, this may be your only option. Other people use an immersion heater as a backup for their main boiler.
