Why fit an unvented cylinder?
+−
Mains-pressure hot water at every tap and shower, no loft tank, freed-up loft space, and the option to run multiple showers without flow dropping. Especially good for larger Lancashire homes with 2+ bathrooms.
Are you G3 qualified?
+−
Yes — every unvented install we carry out is by a fully G3-qualified engineer, with discharge pipework, T&P + expansion valves correctly sized, Building Control notified and a full Gas Safety Certificate provided.
Which cylinder brands do you fit?
+−
Megaflo (Heatrae Sadia), Telford, Joule and most major UK unvented brands — we will recommend the right size and brand based on your hot-water demand and boiler.
Does an unvented cylinder need annual servicing?
+−
Yes — G3 best practice is an annual safety check of the expansion vessel, T&P valve and discharge pipework. We can bundle it with your boiler service.
