Not everyone has a combi boiler, there are thousands of homes in and around London with hot water cylinders. These rely on either one or two immersion heaters and normally are run off a timer or economy 7 rate electricity. These hot water cylinders directly heat the water by electricity, this results in hot water temperatures and quick recovery times.
There are many pros and cons to these units, pros include no gas is needed and these units can be located in a cupboard or a suitable space such as loft making them perfect for homes in London space.
But on the con side, due to hard water and poor maintenance hot water cylinders are susceptible to damage on the immersion heaters and problems occur due to the fact these immersion heaters have to do a lot of work. This is because they are submerged in water and home owners and tenants can’t see when the heaters are being attacked by lime scale or ready to rupture due to age and high demand.
