Are you still relying on an outdated oil-fired boiler to heat your home? You could be missing the opportunity to upgrade your heating system completely free of cost.
Are you still relying on an outdated oil-fired boiler to heat your home? You could be missing out on a warmer, more energy-efficient home and the opportunity to upgrade your heating system completely free of cost. Thanks to the ECO4 Scheme, thousands of UK homeowners are replacing their old, inefficient oil boilers with new energy efficient condensing boilers and reaping the rewards in terms of lower energy bills, reduced carbon footprint, and improved comfort.
Are you a UK homeowner and have never claimed a free boiler grant yet?, this could be the perfect time to get started. In this guide brought to you by Cozyfy, we explain everything you need to know about replacing your oil boiler with a condensing boiler, how to benefit from the Free Boiler Scheme, and why the ECO4 boiler replacement scheme is a game changer for energy savings.
Why Replace Your Oil-Fired Boiler?
An oil boiler might have served your home for years, but these systems are now considered outdated and inefficient compared to modern alternatives. Here’s why making the switch makes so much sense:
Outdated Technology
Oil boilers typically operate at lower energy efficiency ratings, often below 70%, meaning more than a quarter of your energy is wasted. In contrast, condensing boilers achieve efficiency levels of over 90%.
Rising Oil Prices
Heating oil prices are volatile and can fluctuate drastically. Upgrading to a gas combi boiler or renewable option under the ECO4 reduces dependence on oil and stabilizes your energy costs.
A condensing boiler is a modern, energy-saving heating system designed to make the most out of the fuel it uses usually gas or LPG. Unlike older systems, such as oil-fired boilers, condensing boilers reuse the heat from exhaust gases that would otherwise be wasted. This smart design significantly improves efficiency and helps lower your energy bills.
How A Condensing Boiler Works?
A condensing boiler is a modern, highly efficient heating system designed to make the most of the heat it produces. Unlike older boilers that waste a lot of energy, condensing boilers recover and reuse heat that would otherwise be lost through the flue. Here’s a simple breakdown of how it works:
1. Heat Generation: The boiler burns gas or oil to create heat, just like a traditional boiler. This heats up the water that circulates through your radiators and taps.
2. Heat Recovery from Exhaust Gases: In a non-condensing boiler, hot gases (usually around 200°C) escape through the flue. But in a condensing boiler, these gases pass through a secondary heat exchanger which extracts extra heat from the exhaust.
3. Condensation Process: As the flue gases cool down, they reach a temperature where water vapour condenses back into liquid water (called condensate). This condensation releases latent heat, which the boiler recycles back into the system to heat your home.
4. Condensate is Drained Away: The cooled water (called condensate) is drained through a boiler condensate pipe into your home’s wastewater system.
5. Efficient Water Heating: The result is a heating system that achieves an energy efficiency rating of up to 90% or more, significantly lowering fuel bills and emissions.

Eligible Property Types
- Off-grid homes relying on oil or LPG heating
- Properties without modern insulation
- Houses in rural or hard-to-heat areas
Oil Fired Boiler vs Condensing Boiler
When comparing an oil-fired boiler to a condensing boiler, the efficiency and eco-friendliness of the latter stand out clearly.
Energy Efficiency: Traditional oil boilers typically operate at around 60–70% efficiency, while modern condensing boilers can reach over 90%, helping you save more on heating bills.
Carbon Emissions: Oil boilers release significantly more CO₂, while condensing boilers reduce your carbon footprint by reusing heat from exhaust gases.
Fuel Type and Cost: Oil is often more expensive and subject to market fluctuations, while gas condensing boilers offer a more stable and cost-effective heating option.
Maintenance and Longevity: Condensing boilers are easier to maintain and have fewer moving parts compared to oil systems.
Under the ECO4, Cozyfy helps eligible households replace their old oil boiler with a new, energy-efficient condensing boiler completely free of cost. It’s a smart switch for your home, your wallet, and the planet.
