When is it Time For a new boiler?
Several signs indicate it might be time to consider a new boiler installation:

Age: Boilers typically last 10-15 years. If yours is nearing or exceeding this lifespan, it may be prone to breakdowns and decreased efficiency.

Increasing Energy Bills: A sudden spike in energy costs without increased usage could mean your boiler is working harder than it should.
Frequent Repairs: Constant repairs can quickly add up. Investing in a new, reliable boiler might be the more cost-effective solution.

Strange Noises: Banging, clanking, or whistling sounds often indicate internal issues that may require a replacement.
Leaks: Any water leakage should be addressed immediately, as it could lead to significant damage and signify a failing boiler.
