Benefits of Installing Unvented Cylinders
Unvented cylinders deliver powerful showers, free up valuable space, and future-proof your home for renewables. With safer, cleaner, and quieter performance, they’re the smart upgrade for modern living—expertly installed by T.M.S. Mechanical Services.
Why you can trust our content
We understand that the boiler industry can be confusing, with plenty of outdated or misleading information. That’s why we rely only on trusted, proven sources to guide our advice and installations:

Vented hot-water systems with loft tanks belong to another era. Unvented cylinders deliver hotel-grade showers at mains pressure, reclaim loft space, and future-proof homes for renewables. Here’s why making the switch with T.M.S. Mechanical Services is a game-changer.
- High water pressure without pumps:
Vented systems limp along at 0.2 bar; unvented units supply 2–3 bar, powering rainfall showers and rapid bath fill-ups without noisy booster pumps. - Space-saving design frees your loft:
Eliminating the cold-water tank liberates valuable storage and removes the risk of ceiling-destroying leaks. Gravity no longer dictates cylinder location—you can tuck it into a garage or utility. - Superior hygiene and water quality:
Feeding directly from the mains eliminates stagnant loft-tank water and reduces legionella risk. Internal potable-grade expansion vessels keep the supply pristine. - Energy efficiency through better insulation:
Factory-applied foam lagging cuts standing heat-loss to ~1 kWh/24 h. Twin-coil cylinders integrate seamlessly with heat pumps or solar-thermal panels for Net-Zero readiness. - Simultaneous use of multiple outlets:
Mains-pressure storage means no more shower-schedule choreography in busy households or B&Bs. - Built-in safety mechanisms:
Temperature-and-pressure-relief valves, dual thermostats, and G3-certified installation deliver rock-solid safety. - Reduced system noise:
No cistern glugging, no pump whine—just tranquil plumbing. - Increased property value and appeal:
“Mains-pressure hot water” in a listing commands higher offers and happier tenants. - Compatibility with renewables:
Twin- or triple-coil models accept heat from boilers, heat pumps, and solar panels—future proof built-in. - Longer manufacturer warranties:
Stainless-steel cylinders often carry 25-year anti-corrosion cover.
