What are Back Boilers and Why Should They Be Replaced?

Back boilers were once a common sight in UK homes. Typically installed behind a fireplace, these older-style boilers used the heat from the fire to warm both water and living spaces. Back boilers are now considered outdated and inefficient. If you are looking to replace your back boiler with a more energy efficient heating and hot water system then you could qualify for a back boiler removal grant.

Reasons to replace your back boiler

• Back boilers use excessive energy consumption, leading to significantly higher energy bills.
• Safety Risks: An old, neglected back boiler can pose serious safety hazards to you and your family. Cracks, corrosion, and improper maintenance can increase the risk of carbon monoxide leaks, a silent and deadly threat. Additionally, the high temperatures associated with back boilers can heighten the risk of fire hazards.
• Environmental Impact: Back boilers are major contributors to carbon emissions due to their heavy reliance on fossil fuels.
• Repair Difficulties: Finding qualified technicians to repair an aging back boiler can be a challenging and costly endeavor.
