Powerful Hot Water Without a Cold Water Tank
An unvented cylinder stores hot water under mains pressure, allowing it to deliver strong hot water flow without relying on a traditional cold water storage tank in the loft.
This can make an unvented system a good option for homes where strong hot water performance is important, particularly where several taps, showers or bathrooms may be in use.
Benefits of an Unvented Hot Water Cylinder
Mains-Pressure Hot Water
Hot water is supplied from the cylinder using the incoming mains water pressure rather than a gravity-fed tank.
Strong Water Flow
A correctly specified system can provide strong hot water performance for showers, taps and multiple bathrooms.
No Loft Tank Required
Because the cylinder is supplied directly from the mains, a traditional cold water storage tank in the loft is not normally required.
Stored Hot Water
A correctly sized cylinder stores a useful volume of hot water ready for use around the home.
Installation, Annual Servicing & Repairs
Unvented cylinders contain important pressure and temperature safety controls. Kassgas provides qualified support throughout the life of the system.

We Recommend Servicing Your Unvented Cylinder Every Year
Unvented cylinders operate under mains pressure and include safety components designed to control temperature and pressure. An annual service gives a qualified engineer the opportunity to inspect the system, check key safety components and identify developing problems.

Unvented Cylinder FAQs
Straightforward answers to common questions about unvented hot water cylinders.
What is an unvented hot water cylinder?
An unvented cylinder stores hot water and is supplied directly from the mains rather than relying on a traditional cold water storage tank. This allows the system to deliver hot water at mains pressure.
What does G3 mean?
G3 relates to the requirements covering hot water storage systems within the Building Regulations. Engineers working on unvented hot water systems need the appropriate knowledge and qualification for this specialist work.
How often should an unvented cylinder be serviced?
Kassgas recommends having your unvented hot water cylinder professionally serviced every year. Annual servicing allows important safety components and the general condition of the system to be checked.
Can Kassgas repair an existing unvented cylinder?
Yes. Kassgas provides fault finding and repairs for suitable unvented hot water systems as well as installation and annual servicing.
Why is my unvented cylinder losing pressure?
Pressure or performance problems can have several causes and should be properly diagnosed. If your cylinder is losing pressure or behaving differently, contact Kassgas so the system can be inspected.
Can an unvented cylinder supply more than one bathroom?
An appropriately sized and correctly specified unvented system can be suitable for homes with multiple bathrooms. The available mains water flow, pressure and expected hot water demand all need to be considered when choosing the system.
Do unvented cylinders need a cold water tank in the loft?
Normally no. An unvented cylinder is supplied from the incoming mains water supply, so it does not normally require the traditional cold water storage tank used by older gravity-fed systems.

Our Happy Customers!
We rang Kassgas on Wednesday afternoon. By Thursday afternoon we had a new boiler. Billy fitted our boiler, he was extremely polite and tidy he even took his shoes off each time he came into the house. Not enough words to praise him enough, he took time to explain how to work the new boiler and controls to two pensioners.
Billy and Matt were about to leave when we mentioned that our stop tap was leaking, they stayed behind and fit a new one. It was heartwarming to meet two young men who didn’t want to rip us off.
We would and already have spread the word about this company.

Billy and Matt just installed a new boiler. They recommended Ideal with a 12 year warranty. They turned up on time within a week of providing a very good quote. they removed the old boiler, installed the new one, flushed the radiators, added inhibitor, installed new halo wireless thermostats and checked everything was working ok in the space of 5 hours. They removed all the rubbish and left a very tidy finish.
I would definitely recommend themWould definitely recommend Kassgas if you have any heating or boiler problems.
