The cost of installing a vented or unvented hot water cylinder typically ranges from £500 to £3,500, depending on factors such as the type and size of the cylinder, whether it’s a new install or replacement, and the complexity of the job.
Vented systems are generally more affordable, starting around £500 and going up to £1,500, with installation usually completed in a day.
Unvented systems, which may require plumbing, electrical, or water main upgrades, tend to cost between £900 and £3,500 and can take 1–2 days to install.
Heating & Water System Separation – Dental Practice
High Wycombe
We were called out to a dental practice in High Wycombe due to issues with their heating system not working. On investigation, we discovered that the building had been split into two separate units—a dental practice on the ground floor and a flat above—but the water and heating services had not been properly separated.
Our task was to separate the services for both properties, ensuring each had its own independent heating and hot water system. For the dental practice, this involved converting the system to a sealed setup and installing a new unvented hot water tank to provide efficient, reliable performance.
Despite the complexity of the job, the outcome was a fully modernised, compliant system—and a great result for our client, improving functionality and reducing future maintenance issues.
Vented cylinders rely on a cold water tank and gravity, while unvented systems are fed directly from the mains, offering better pressure and no need for a loft tank.
Vented systems typically take one day to install, while unvented systems may take 1–2 days depending on complexity.
Prices range from £500 to £3,500 depending on the type of cylinder, installation complexity, and any required system upgrades.
Yes, especially for unvented systems which require a G3-certified engineer to ensure safe and legal installation.
