Water Heater Installation EXPERT

A Reliable Hot Water Supply for Your Home

Whether your current cylinder has stopped heating properly, you’re converting from a tank system, or you’re building an extension that needs more hot water capacity, we’ll help you pick a system that fits your household size and how you actually use hot water.

If a failing cylinder is also linked to a wider issue, we can check your pipework for leaks or discuss a water softener at the same time to protect the new system.

Water Heater Installation GUIDE

Is It Time to Replace Your Hot Water Cylinder?

Most hot water cylinders last 10-15 years, but a few signs suggest it’s worth replacing sooner: rusty or discoloured water, a cylinder that’s noisy or leaking, or hot water that runs out much faster than it used to. Unvented cylinders in particular need an annual safety check, since the safety valves are what keep the system running safely under pressure.

If you’re not sure whether to repair or replace, we’ll give you a straight answer based on the age and condition of your current system.

COMMON WARNING SIGNS

Don't Ignore These Signs

If any of these sound familiar, your hot water system is worth getting checked before it fails completely.

Discoloured Water

Rusty or discoloured hot water often means corrosion inside an ageing cylinder.

Running Out of Hot Water Fast

A cylinder that used to last through a shower and now runs cold quickly may be losing capacity.

Banging or Knocking Noises

Loud noises from the cylinder or pipework can mean sediment build-up or a failing component.

Leaking Around the Cylinder

Water pooling near the base of the cylinder usually means a fitting or valve needs attention.

Inconsistent Water Temperature

Water that fluctuates between hot and cold during use can indicate a thermostat or valve fault.

Cylinder Over 15 Years Old

Older cylinders become less efficient and harder to source parts for as they age.
