Common issues with unvented cylinders include leaks, pressure drops, temperature fluctuations, and noisy operation. Regular maintenance can help prevent these problems.
The decision to repair an old unvented cylinder depends on its condition and repair costs. If the repair costs are significant and the cylinder is outdated, it may be more beneficial to invest in a new system.
For new cylinder prices check out our pages on indirect unvented cylinder prices and direct unvented cylinder prices.
Common signs include loss of hot water pressure, leaks, strange noises, inconsistent water temperature, and frequent drips at the tundish.
It’s highly recommended to hire a professional for unvented cylinder repairs. They have the expertise and knowledge to diagnose and fix issues safely and efficiently.
It’s not advisable to attempt repairs yourself unless you have the necessary training and experience. Unvented cylinders involve pressurised systems and require specialised knowledge to handle safely.
The repair cost depends on the extent of the damage and the required parts. It’s best to contact us for a detailed assessment and a personalised cost estimate.
Our expert technicians can repair various issues, including leaks, faulty pressure valves, thermostat problems, expansion vessel faults, and more.
In many cases, repairs can effectively resolve issues and extend the lifespan of the cylinder. However, if the cylinder is old, inefficient, or suffers from frequent breakdowns, a replacement might be more cost-effective in the long run.
Regular maintenance is key to preventing future issues. It’s recommended to have your cylinder serviced annually by a qualified professional to ensure optimal performance and detect any potential problems early on.
