What Is An Unvented Hot Water Cylinder System?

Unvented hot water systems have cylinders that are supplied by mains water and have no header tanks. Cold mains water enters the cylinder at the bottom, is heated by a heat source, such as a boiler, and then is delivered at the mains pressure to the outlets.

When carefully designed, unvented hot water cylinders can provide lots of flow that can be used simultaneously to supply multiple hot water outlets.

Typically, the pressure at which these systems operate at is dictated by the mains pressure, although pumps may be used to increase pressure where low.

Unvented hot water systems are known as the premium method for hot water storage and delivery. It is possible to have more than one heat source to heat the water in the cylinder, which allows for such things as solar panels to be used to reduce fuel costs.

Design and the quality of the installation are paramount in ensuring that unvented hot water systems perform as specified. Only a highly-skilled and experienced company like us can ensure that these systems work as they should. Few companies are operating in Bromyard who can deliver what we do.

What Happens When You Cut Corners And Use The Wrong Company!

Pressure, flow, pipe sizes, pipe routes and other factors all affect the performance of an unvented hot water cylinder. Unvented hot water cylinders can produce excellent results with careful consideration and design. Potentially, three to four showers could run from a single cylinder simultaneously, which can be further pushed through advanced plumbing system design and the use of cylinders banks. These systems need intelligence, experience and skill to be designed and implemented successfully. Cut corners here, and you may be sadly disappointed with your investment’s performance!

It is extraordinary how many poorly installed cylinders we find in Bromyard and the surrounding areas during our servicing tasks! We regularly report faults found to clients who have bought homes with these systems fitted or had them installed by others. In many instances, this has to lead to the customer chasing rectification from builders and plumbing companies or paying to have the work put right themselves.

Following our findings of faults on unvented systems in neighbouring properties, we have experienced whole blocks of flats and large numbers of homes on new building estates come together to have defects corrected from developers and homebuilders. These systems are often installed wrong, not everybody has the skillset to be able to install them well!

Poorly Installed Unvented Systems Can Kill!

An unvented cylinder that has been installed poorly may pose a significant risk. In the worst case scenario, these cylinders can explode and destroy properties they are contained within due to steam gas explosions! After a catastrophic discharge, poorly installed cylinders may also fail to remove high-temperature steam and water to a safe location. There are numerous situations in this country where people were killed or seriously hurt as a result of the poor installation of this equipment. However, properly installed uninvented hot water cylinders are exceptionally safe and work fantastically.

It is vital that you use the right installer when installing these systems!
