Vented or Unvented, Which Suits You

A vented cylinder is fed from a tank in the loft and is simple and cheap to maintain. An unvented cylinder runs at mains pressure, so showers are stronger and no loft tank is needed. Unvented needs good incoming mains pressure to work well, which we test before quoting.

Getting the Size Right

Size is based on how many bathrooms you have and when people use them, not on what was there before. Too small and the hot water runs out mid shower. Too big and you pay to heat water nobody uses. We work it out with you before ordering anything.

Hard Water and Cylinder Life

Bedfordshire water is hard, so scale settles on immersion heaters and coils and slowly reduces how much hot water you get. Fitting a scale reducer on the mains and having the cylinder checked yearly keeps it working and protects the parts inside.

Frequently Asked Questions

How long does a hot water cylinder installation take?

A like for like replacement is usually a single day. Changing from a vented to an unvented cylinder takes longer, because the pipework, discharge pipe and controls all change. We confirm the timescale at the quote so you know how long the hot water is off.

Does an unvented cylinder need servicing?

Yes, once a year. The expansion vessel, pressure relief valve and thermostat are all checked and the cylinder is inspected for scale. Manufacturers require it to keep the warranty valid, and it is a safety item because the cylinder holds water under mains pressure.

Why does my hot water run out so quickly?

Usually the cylinder is undersized for the household, the coil is furred up with scale, or the timer and thermostat are set poorly. A failed immersion heater does the same. We test the cylinder and controls first, because a cheap fix often solves it without a replacement.

About us

We install hot water cylinders as part of new heating systems and as standalone replacements when an old one starts leaking or scaling up. Unvented work is carried out by qualified engineers, as the regulations require. Twenty years of local installs means very few airing cupboards surprise us.
