No need for a cold water tank in the loft
Safer and more hygienic than traditional vented systems
Energy-efficient and compatible with solar thermal systems
Why Unvented Cylinders Need Servicing
Unvented cylinders operate under mains pressure, which means they deliver powerful water flow to your taps and showers. However, this also means they are pressurised systems—and without regular maintenance, they can pose serious risks.
Annual servicing ensures
Safety valves are functioning correctly to prevent overpressure or overheating
Temperature controls are accurate to avoid scalding or bacterial growth
Expansion vessels are properly pressurised to handle thermal expansion
No leaks or corrosion are present that could lead to costly damage
Servicing must be carried out by a G3-certified engineer, which our technicians are. This is a legal requirement under UK Building Regulations
Risks of not servicing your cylinder
Neglecting your unvented cylinder can lead to:
Pressure build-up and potential system failure
Invalidated warranties
Reduced energy efficiency
Leaks, water damage, or even explosion in extreme cases
Many homeowners are unaware of these risks, which is why we’re committed to raising awareness locally in Ashburton and Devon.
