Megaflo-style unvented cylinder replacement in Barnet — like-for-like swaps of failed stainless cylinders with minimum downtime.
Megaflo-Style Cylinder Replacement in North London, done properly the first time
Large stainless unvented cylinders eventually fail, usually through the internal coil or a corroded connection, and the symptom is often lukewarm water or a persistent leak in the airing cupboard.
We replace like-for-like where the existing footprint and discharge route work, or resize if your household has changed since the original install.
Most replacements are a single-day job, and we aim to have hot water back on the same evening.
