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.

Sharif bhai did a very good job in my property. He fitted the shower properly and fixed the leak issue. He checked everything carefully and made sure there was no more leaking after the work finished. He was polite, professional, and helpful. The work was neat and clean, and the shower is now working very well. I am happy with his service and I would recommend Sharif bhai to others for plumbing work.

I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving. What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler. Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.
