Unvented Cylinder Servicing in Kent
Unvented hot water cylinders need annual servicing – it’s a manufacturer requirement and essential for safety. As a G3 qualified engineer, I can service all types of unvented cylinders.
What’s Included in a Service
A proper unvented cylinder service covers all the critical safety components:
Temperature and pressure relief valve – This is your cylinder’s main safety device. I’ll test it to ensure it opens at the correct pressure and temperature, and check for any signs of limescale or corrosion.
Expansion vessel – Unvented systems include an expansion vessel to handle thermal expansion. I’ll check the pre-charge pressure and inspect for any signs of failure.
Pressure reducing valve – This controls the incoming water pressure. I’ll test it’s working correctly and check for any debris buildup.
Tundish and discharge pipework – I’ll check these are clear and correctly installed to safely discharge any water if a safety valve operates.
Anode rod (if fitted) – Some cylinders have a sacrificial anode to prevent corrosion. I’ll check its condition and recommend replacement if needed.
General inspection – I’ll look for any signs of leaks, corrosion, or damage to the cylinder and pipework.
Why Annual Servicing Matters
Safety first. The safety devices on an unvented cylinder exist for a good reason – to prevent dangerous pressure buildup. Regular testing ensures they’ll work when needed.
Maintain your warranty. Most manufacturers require annual servicing by a G3 qualified engineer. No service record = no warranty claim if something goes wrong.
Prevent breakdowns. Small issues caught during a service are much cheaper to fix than emergency callouts.
Extend cylinder life. A well-maintained unvented cylinder can last 15-20 years. Neglected ones fail much sooner.
Landlord Requirements
If you’re a landlord with unvented cylinders in your property, annual servicing is strongly recommended as part of your duty of care to tenants. While not a legal requirement like the gas safety check, it demonstrates due diligence.
Fair, Fixed Pricing
I charge a fair, fixed price for unvented cylinder servicing. You’ll know the cost upfront – no surprises.
