From compact unvented cylinders to traditional tank setups, we install and replace hot water systems for homes across St Albans. Fixed quotes, honest advice on which system suits your household, and a tidy installation.

Water Heater Installation EXPERT
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
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
If any of these sound familiar, your hot water system is worth getting checked before it fails completely.
Rusty or discoloured hot water often means corrosion inside an ageing cylinder.
A cylinder that used to last through a shower and now runs cold quickly may be losing capacity.
Loud noises from the cylinder or pipework can mean sediment build-up or a failing component.
Water pooling near the base of the cylinder usually means a fitting or valve needs attention.
Water that fluctuates between hot and cold during use can indicate a thermostat or valve fault.
Older cylinders become less efficient and harder to source parts for as they age.
