Vented Cylinder Replacement
Vented Cylinder Replacement
Vented hot water cylinder replacement across North London — copper and foam-lagged cylinders swapped quickly on gravity-fed systems.
Vented Cylinder Replacement in North London, done properly the first time
Plenty of Barnet homes still run a traditional vented cylinder fed from a loft tank. When one starts leaking or the coil fails, replacement is straightforward and considerably cheaper than converting the whole system.
We fit modern foam-lagged cylinders with far better standing heat loss than the old copper ones, and take the opportunity to fit a proper cylinder thermostat and zone valve if the controls are outdated.
If it is the right moment to consider moving to unvented or to a combi, we will lay out the options and costs honestly rather than assuming.
