Do you know condensing boilers can significantly reduce your carbon footprint? These boilers are more efficient than their non-condensing counterparts, they’re more energy efficient and cut utility costs. Moreover, the government has banned all non-condensing boilers. So you can no longer buy one, let alone install it on your property.
This does sound like a worry if you’re still using the outdated, inefficient, old, non condensing boiler. The UK government introduced a plan to ensure everyone uses the latest technology aiding in a net zero carbon emissions plan. ECO 4 scheme is a major part of it offering grants for boilers. Your eligibility gets you a brand-new condensing boiler with free insulation. Once installed, you’ll feel a big difference in its efficiency and cutting your costs.
What’s a condensing boiler?
A condensing boiler is a modern type of boiler you often find at home. It saves money and reduces pollution. Firstly, when you burn gas or oil, it makes hot gas. However, in old boilers, this gas just goes into the air and is wasted. But in a condensing boiler, we catch that hot gas and use it again. It goes through a thing called a heat exchanger and gets reused. Then, depending on the type of boiler, the heat goes to either the radiators or the hot water system. So, in simple terms, a condensing boiler is like a recycling machine for heat!
What’s the difference between condensing and non-condensing boilers?
The key difference between condensing and non-condensing boilers boils down to how they handle heat. Non-condensing models work by burning fuel to heat water. Unfortunately, they waste a lot of energy because the hot exhaust gases containing valuable heat simply escape through the flue. Condensing boilers, on the other hand, capture that wasted heat from the exhaust gases. They cool down the gases, causing water vapour to condense into a liquid. Consequently, they release even more heat. Moreover, this extra heat is then used to pre-heat the water returning to the boiler. So this makes them much more efficient.
Here’s a quick comparison:
| Feature | Non-condensing Boiler | Condensing Boiler |
| Efficiency | Up to 80%

| Energy Bills | More expensive | Less expensive |
| Environmental Impact | Higher emissions | Lower emissions |
| Cost | Lower upfront cost | Higher upfront cost |
Why are condensing boilers more efficient?
Condensing boilers are more efficient because they use heat better. As mentioned earlier, in old boilers, heat was mostly wasted. They can be over 90% efficient, while non-condensing boilers are only 70-80% efficient.
But with condensing boilers, the heat from the circulated water is reused. It goes through a part called a condenser before being vented out. This part helps warm up the water again before it goes back to the burner. So, the water is already warmer when it reaches the burner. This means the burner doesn’t need to work as hard to heat it up further.
As the water gets warmer, it also helps cool down the gases from the flame. This makes water vapour condense, which is really efficient. As a result, condensing boilers save more money and are greener. They use less fuel and produce fewer emissions.
How much efficient are condensing boilers?
Condensing boilers grab heat escaping in old boilers, making them super efficient. Forget 70-80%, these boilers hit over 90% efficiency, using less fuel for warmth. Moreover, their other efficiency measures include:
- Go green: Less fuel means fewer carbon emissions, good for you and the planet.
- Small size, big benefits: These boilers fit in tight spaces, unlike bulky old boilers.
- Peace and quiet: Enjoy the silence! These machines run much quieter than old models.
- Lasts for years: Proper care means this boiler will keep you warm for a long time.
- Quick install: These are easy to install and fast, minimising disruption.
- Warmth & savings: Get both! Condensing boilers keep you cosy and save you money on energy bills.
How much do condensing boilers save on bills?
- Slash gas bills: Condensing boilers use less fuel. As a result, you can ensure significant savings on your annual gas bill.
- Save Up to £310: Estimates show potential savings of up to £310 per year, putting money back in your pocket.
- Highly efficient: Over 90% efficiency means you pay less for the same level of warmth.
- Lower fuel consumption: These boilers squeeze more heat from fuel, reducing your overall fuel needs.
- Long-term savings: The upfront cost is balanced by years of lower energy bills.
- Reduced maintenance costs: Modern condensing boilers often require less frequent maintenance.
- Improved home value: These boilers can increase your home’s value when selling.
- Future-proof investment: Condensing boilers are the future of heating, making them a smart financial choice.
- Warmth without spending a lot: Enjoy a comfortable home without worrying about sky-high energy bills.
Bottom line
Condensing boilers are a clear winner when it comes to cost savings and efficiency for UK homes. They slash energy bills with impressive efficiency ratings, putting money back in your pocket year after year. Moreover, there are grants for boilers for low-income households. These grants provide brand-new condensing models. If you qualify, you may get a quieter, more eco-friendly heating system that will keep your home warm and comfortable for years to come. So if you’re looking to upgrade your boiler, a condensing boiler is a smart investment that pays for itself in the long run.
