Common Boiler Issues We Fix

Boiler Leaks

Leaks usually come from worn valves, pump seals, or internal corrosion. They reduce system pressure and can lead to bigger failures if not checked quickly.

No Heat or Low Heat

A loss of heat often points to thermostat faults, air in the system, or ignition problems. These issues prevent the boiler from circulating heat properly.

Loud Noises (Kettling)

Rumbling or banging sounds mean mineral buildup is restricting water flow. This puts extra strain on the boiler and can damage internal components.

Pilot Light Issues

A pilot that won’t stay lit is usually caused by a bad thermocouple or weak gas flow. This stops the boiler from firing reliably and needs prompt repair.

Types of Boilers

Designed to work with a separate hot water cylinder and cold water tank, conventional boilers are ideal for spaces with high water usage and simultaneous demand across multiple fixtures.

These energy-efficient systems recover heat from exhaust gases, reducing fuel usage and lowering emissions. A smart choice for maximizing efficiency and minimizing energy costs.

Compact and powerful, combi boilers deliver heating and hot water on demand without the need for additional storage tanks—perfect for maximizing usable space.

Boiler Maintenance Tips

Keep your boiler efficient and long-lasting with these quick tips:

Schedule Annual Servicing

Have a licensed technician inspect your boiler every year to catch issues early, clean internal components, and ensure safe operation.

Bleed Radiators Regularly

Air trapped inside radiators can lower heating efficiency. Bleed them as needed to restore full performance and heat distribution.

Monitor Water Pressure

Keep an eye on your system’s pressure gauge. If it drops too low, it could signal a leak or performance issue that needs attention.

How do I know if my boiler needs repair or full replacement?

If your boiler is over 15 years old, needs frequent repairs, heats unevenly, or causes rising energy bills, replacement may be more cost-effective. A technician can inspect the system and recommend the best option for your home.

Why is my boiler not heating evenly or making strange noises?

Uneven heat or noises often come from air in the system, failing pumps, thermostat issues, or worn components. A professional can diagnose the cause quickly and prevent further damage.

How long does a boiler installation or repair usually take?

Most repairs can be completed in one visit. Boiler installations typically take one full day, depending on your home’s setup. We provide a clear timeline before starting any work.

Will a new high-efficiency boiler actually reduce my heating costs?

Yes. High-efficiency boilers use less fuel to produce the same amount of heat, and many homeowners see energy savings of 15–30%. You’ll also get more consistent heat and fewer maintenance issues.
