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 Stone.
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 Stone Properties
Common Heating Issues in Stone
Stone's diverse housing stock presents varied heating challenges that keep our engineers' expertise sharp. The period properties around St Mary's Church and the older cottages throughout the village often have heating systems that weren't designed for modern comfort expectations. Solid walls, high ceilings, and original features like sash windows make these properties more challenging to heat efficiently, and older heating systems work harder as a result. We frequently recommend upgrading to modern condensing boilers with improved controls, which can significantly reduce running costs while maintaining period character. Many of these older properties still have conventional boilers with separate hot water cylinders, and the boilers themselves are often reaching the end of their serviceable life. The larger properties in the Stone Castle area sometimes have complex heating requirements with multiple zones needed to heat spacious rooms efficiently. We've encountered inadequate system design in some cases, where the original heating installation didn't properly account for room sizes or the property's layout. Mid-century properties throughout Stone are at the stage where boilers installed in the 1990s and early 2000s need replacement, and we help homeowners navigate the upgrade to more efficient modern systems. Across all property types, frozen condensate pipes during winter are common where external pipes haven't been insulated. We also see aging radiators that have become inefficient over decades and benefit from replacement.

Frequently Asked Questions
Common questions about unvented cylinder services in Stone
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.
