Expert System Boiler & Unvented Cylinder Conversions
Tired of weak showers and waiting ages for your bath to fill? If your home still relies on an old-fashioned gravity-fed system with tanks in the loft, a modern conversion could be the best upgrade you ever make. We specialise in system boiler and unvented cylinder installations across Redditch, Bromsgrove, Worcester, and the surrounding Midlands.
Upgrade Your Flow: Gravity to High-Pressure Conversions
Many traditional homes use a “gravity-fed” setup, where water pressure depends entirely on how high your cold water tank sits in the loft. By converting this to a System Boiler and an Unvented Hot Water Cylinder (like a Megaflo), we remove those old tanks and let your mains water pressure do the hard work instead.
What is a System Boiler & Unvented Cylinder Setup?
This is the “Powerhouse” of home heating. A system boiler houses the major heating components internally, while the unvented cylinder stores a large volume of hot water at mains pressure.
- Powerful Showers: No more noisy pumps! Your showers and taps will perform at full strength from your mains water supply.
- Hot Water Everywhere: Unlike a Combi boiler, this setup allows you to run multiple hot taps or showers at the same time without the pressure dropping.
- Loft Space Recovery: We remove bulky, heavy cold-water storage tanks from your loft, freeing up space and reducing the risk of leaks or frozen pipes.
- High-Efficiency Heating: Modern system boilers are over 90% efficient, heating your cylinder and radiators faster than ever before.
The “Gold Standard” Installation Process
Converting from a gravity system to an unvented setup is a precision job that requires specialist G3 Unvented qualifications. We follow a meticulous process to ensure your system is safe and high-performing:
- Mains Pressure & Flow Test: We verify your incoming supply is strong enough to deliver that “power shower” experience.
- Tank Removal & Pipework Upgrades: We safely bypass loft tanks and replace outdated pipework with 22mm copper where necessary to handle the increased pressure.
- Safety First (G3 Certified): Our engineers are fully G3 qualified to install the specialized safety valves and expansion vessels required by law.
- System Chemical Clean: We perform a thorough flush of your radiators before the new boiler is connected to protect your investment from old sludge.
- System Balancing: Once installed, we balance your radiators to ensure the whole house heats up evenly.
The Advantages of Making the Switch
| Feature | Old Gravity System | New Unvented System |
| Shower Pressure | Weak (depends on height) | Powerful (Mains Pressure) |
| Multi-Tap Use | Poor (pressure drops) | Excellent (High flow rates) |
| Loft Space | Wasted by large tanks | Tanks Removed / Free Space |
| Water Hygiene | Open tank (dust/debris) | Sealed & Hygienic |
| Efficiency | Low (Heat loss from pipes) | High (Modern insulation) |

Common Installation Questions
Do I need a pump for my shower with an unvented cylinder?
No! Because the water is delivered at mains pressure, you get a powerful flow naturally without the noise or cost of a mechanical pump.
Will my old pipes burst with the higher pressure?
As part of our “Gold Standard” process, we inspect your existing pipework for weak spots or old lead piping and advise on any necessary upgrades before switching the pressure on.
How much space does the cylinder take up?
While we clear the loft, the cylinder usually sits in an airing cupboard. We can source various sizes, including slimline models, to fit your available space.
