What Our Unvented Cylinder Services Covers
How Our Unvented Cylinder Services Works
From initial contact to completed work, here's what you can expect when you choose us for unvented cylinder services in Greenhithe.
Book Your Cylinder Service
Contact us to book your annual unvented cylinder service. We can service your cylinder on its own, or if you have both a boiler and unvented cylinder, ask about our combined service package (Boiler + Cylinder for £180) which offers better value than booking separately.
Appointment Confirmation & Engineer Tracking
You'll receive confirmation of your appointment, and on the day, we'll send you a text when your G3-qualified engineer is on the way. Our tracking link lets you see when to expect us - no more wasted days waiting around.
Visual Inspection & Safety Assessment
Our engineer will examine your unvented cylinder and associated pipework, checking for signs of corrosion, leaks, or damage. We'll verify that safety devices are present, correctly positioned, and haven't been tampered with. We'll also check that the installation still complies with current Building Regulations.
Temperature & Pressure Relief Device Testing
We'll test all safety devices including the temperature relief valve, pressure relief valve, and expansion vessel. These critical components must operate correctly to prevent dangerous pressure buildup. We'll verify that discharge pipes terminate safely and meet regulatory requirements.
Expansion Vessel & Pressure Testing
The expansion vessel is crucial for absorbing pressure increases as water heats up. We'll check the vessel's pre-charge pressure and test its operation. If the vessel has lost pressure or failed, it will need recharging or replacement to ensure system safety.
Performance Checks & Adjustments
We'll verify water temperatures, check thermostat operation, and test heating elements (on electric cylinders) or coil performance (on indirect cylinders). We'll ensure your cylinder is heating water efficiently and maintaining the correct stored water temperature.
Service Report & Recommendations
After completing your service, you'll receive a detailed report confirming all safety tests carried out and any recommendations for repairs or component replacement. We'll explain our findings and provide quotes for any additional work needed, allowing you to make informed decisions.
Unvented Cylinder Services for Greenhithe Properties
Common Heating Issues in Greenhithe
The diverse housing stock in Greenhithe means we encounter a wide range of heating issues. In the older Victorian and Edwardian properties, we frequently find outdated heating systems struggling to cope with modern demands. These homes often have traditional radiator systems that were designed decades ago, and many still operate with old conventional boilers in need of replacement. Poor insulation in period properties means heating systems work harder, and we often recommend upgrading to more efficient condensing boilers alongside improved controls. In contrast, the newer developments like Ingress Park present different challenges. While the heating systems are modern, we've seen issues with pressurised systems losing pressure, often due to installation issues or minor leaks that need professional attention. The riverside location brings its own complications - properties near the Thames can experience higher humidity levels, which occasionally affects flue terminals and condensate pipes. We've also noticed that combination boilers in smaller flats sometimes struggle when multiple hot water outlets are used simultaneously, and we can advise on whether a system upgrade might improve performance. Frozen condensate pipes during harsh winters affect both old and new properties, and we offer preventative lagging services to avoid this common problem.

Frequently Asked Questions
Common questions about unvented cylinder services in Greenhithe
What does G3-qualified mean and why is it important?
G3 refers to Approved Document G of the Building Regulations, which covers unvented hot water systems. Anyone who installs, services, or repairs unvented cylinders must hold the G3 Unvented Hot Water qualification. This ensures they understand the safety-critical nature of pressurised hot water systems and can work on them safely and legally. All our engineers are G3-qualified, which means you can trust that the work complies with legal requirements.
How often should I have my unvented cylinder serviced?
We recommend annual servicing for unvented cylinders. This is essential to test safety devices like pressure relief valves and expansion vessels, which protect against dangerous pressure buildup. Most manufacturers require annual servicing to maintain warranties, and landlords must ensure annual servicing for legal compliance. Regular maintenance also prevents efficiency loss and extends the life of your cylinder.
What brands of unvented cylinders do you work with?
We service and repair all major unvented cylinder brands including Megaflo (the most common brand), Heatrae Sadia, Gledhill, Range Tribune, Telford, OSO, and many others. Our engineers have experience with both direct (electric immersion) and indirect (heated by boiler) cylinders, and we can source parts for all common makes and models.
Why is water dripping from the overflow pipe?
Water dripping from the overflow (tundish discharge) usually indicates a problem with the pressure relief valve or expansion vessel. The most common cause is expansion vessel failure - when the vessel loses its air charge, excess pressure from heating has nowhere to go except out through the relief valve. This needs attention promptly as constant water discharge can cause damage and indicates the safety system isn't working correctly.
Can you install a new unvented cylinder if mine needs replacing?
Absolutely. We're fully qualified to install unvented hot water cylinders in accordance with Building Regulations. If your cylinder is beyond economical repair, we'll discuss replacement options including cylinder size, brand recommendations, and whether direct or indirect heating suits your needs. We'll provide a free, no-obligation quote for a complete installation including all required safety devices and pipework modifications.
Is the combined boiler and cylinder service worth it?
If you have both a boiler and an unvented cylinder, our combined service package at £180 saves you £60 compared to booking each service separately (£120 + £120 = £240). It's also more convenient as both services are completed in one visit. For homeowners with this combination, it's by far the most cost-effective way to maintain both systems annually.
What happens if my cylinder fails and needs replacing urgently?
We carry some common unvented cylinder parts and can often resolve issues like failed thermostats or relief valves on the same day. For complete cylinder replacement, we can typically arrange installation within a few days and will recommend temporary solutions in the meantime. We understand that losing hot water is disruptive and will prioritise getting you back up and running as quickly as possible.
