The Hidden Costs of Limescale for Your Boiler and Budget

Limescale might not seem like a major issue, but it can quietly cause serious damage to your heating system, your wallet and the planet.

New research from Save Money Cut Carbon reveals just how much energy is wasted due to limescale build-up, and how much Grimsby homeowners could save with proper prevention.

How Limescale Affects Your Heating

According to British Water, limescale can cause a 12% drop in boiler efficiency. If a typical family home uses 47kWh of gas per day (around £2.82 at current rates), that inefficiency adds up to:

• £139.05 per year in wasted energy

• 0.5 tonnes of extra CO₂ emissions annually

That’s both an economic and environmental cost no one wants to pay.

A Simple Solution: Combimate

One of the most effective ways to prevent limescale is by installing a Combimate. This small but powerful device releases food-safe polyphosphate into your water system to stop limescale forming.

With regular maintenance (replacing the Combiphos crystals annually), research shows:

• £863.50 saved over 10 years

• Return on investment in as little as two years

It’s a smart way to protect your boiler, save on heating bills and lower your household’s carbon footprint.
