Heat Exchangers
The heat exchanger is the core of your boiler. It transfers thermal energy from the burner to the water that heats your home and supplies your taps, working continuously under high temperatures and pressure.
A clean, efficient heat exchanger ensures optimal performance and low energy bills, while a scaled or cracked exchanger can cause significant problems.
Common signs of failure include slow hot water recovery, fluctuating temperatures, water leaks, or unusual kettling noises.
