Why to install a condensing boiler?

Do you know condensing boilers can attain up to 95% efficiency, as opposed to their non-condensing counterparts? Yes, this is true. On top of that, these boilers are eco-friendly. Plus, they can dramatically cut your heating costs. Non-condensing boilers, on the other hand, only achieve 70-80% efficiency! So how do the condensing models manage to achieve this? It’s all due to their proprietary condensing technology. It works by utilizing a heat exchanger. This preheats the water that circulates through the system. As a result, it essentially preserves heat that would otherwise be lost. Now, if you’re looking for free-of-charge condensing boiler installation, there might be free boiler grants available. For example, the ECO4 scheme aims at replacing older, non-condensing boilers with condensing models.  However, not all people could qualify for them. Eligibility criteria differ for these grants, so you need to find out before applying. 

What’s the distinction between a condensing and a non-condensing boiler?

Condensing boilers are highly efficient. They absorb heat from gas and convert it into water, allowing them to work more efficiently. They frequently operate at 90% or higher. Non-condensing boilers, on the other hand, are less efficient. They don’t absorb heat from gas, so they operate at 80% to 85% efficiency. Furthermore, condensing boilers incorporate a second heat exchanger. This collects more heat from the gas and produces water. This allows them to perform better. Non-condensing boilers contain only one heat exchanger and cannot generate water.

Secondly, condensing boilers use cooler gas. It ranges from 50 to 60 degrees Celsius. Non-condensing boilers, on the other hand, use hotter gas, which is often above 100°C. Third, condensing boilers require specific outlets for their cooled gas. They employ plastic. Non-condensing boilers, on the other hand, can operate with standard metal pipes. Finally, since condensing boilers consume less fuel, they produce less pollutants. Non-condensing boilers, on the other hand, require more fuel and so emit more pollution.

Why to install condensing boilers?

Well, there are several reasons that can make you think to opt for condensing boiler installation. Below are the top ones”

Government Regulations

Now the UK government’s regulations make it compulsory that all boilers installed would be condensing models. First of all, the government has banned the production of non-condensing boilers. Now, citizens don’t have any other option except to install condensing models. These fall under UK Building Regulations in 2005. Plus, there are heavy fines if anyone installs a non-condensing boiler.

Condensing boilers have a higher efficiency

Condensing boilers are more efficient because they effectively utilize heat. As previously stated, heat was mostly squandered in older boilers. They can be more than 90% efficient, but non-condensing boilers are only 70–80% efficient. In contrast, condensing boilers reuse the heat from the circulating water. It goes via a condenser before being evacuated. This component helps to warm up the water before returning it to the burner. So, by the time it reaches the burner, the water has already warmed up. This means that the burner does not have to work as hard to heat it up even more.

This causes water vapour to condense, which is extremely efficient. As a result, condensing boilers are both cost-effective and environmentally friendly. They utilize less gasoline and emit less pollution.

Cost-saving benefits of condensing boilers 

  • Condensing boilers reduce fuel consumption and lower gas expenses. As a result, you can significantly reduce your annual gas bill.
  • Save Up to £310: Estimates estimate that you might save up to £310 every year, putting more money in your pocket.
  • High efficiency: Over 90% efficiency results in lower costs for the same amount of warmth.
  • Reduced fuel consumption: These boilers extract more heat from fuel, lowering overall fuel requirements.
  • Long-term savings: Initial expense is offset by lower energy bills over time.
  • Modern condensing boilers often require less regular maintenance, resulting in lower expenses.
  • Improved home value: Installing these boilers can boost the value of your property when selling.
  • Condensing boilers are a future-proof investment for heating.

How can I select the appropriate size of a condensing boiler for my home?

Choosing the appropriate size of a condensing boiler for your home is critical to ensuring effective heating and hot water delivery. Let’s break it down.
Boiler types:

There are three types of boilers: combi, system, and regular. Combi boilers are small and compact, providing rapid hot water. System boilers require a hot water cylinder to store hot water. Traditional heating systems often use regular boilers, which require a cold water tank.  Consider factors such as property size, as larger homes typically require greater output boilers.

  • Allow for 1.5 kW per radiator.
  • Divide approximately 3 kW per bathroom.
  • Well-insulated dwellings may require less heating electricity.
  • Consider local weather conditions.

Boiler Size Calculation: Calculate the kW requirements based on radiators and bathrooms. Use these scores:

  • For tiny radiators, use 1 kW.
  • The average-sized radiator requires 1.5 kW.
  • For large radiators, use 2 kW.
  • Consult a professional installation for personalized service.

Bottom line

When it comes to cost savings and efficiency for UK homes, condensing boilers come out on top. They reduce energy expenses with remarkable efficiency ratings, sending money back into your wallet year after year. Low-income households can also receive boiler grants. These awards provide whole new condensing models. If you qualify, you might receive a quieter, more environmentally friendly heating system that will keep your house warm and comfortable for years to come. So, if you want to improve your boiler, a condensing boiler is a wise investment that will pay for itself in the long run.
