Benefits of Upgrading to a High-Efficiency Boiler

Introduction and Contents

In today’s world, where energy efficiency, running cost and sustainability are at the forefront of consumer choices, upgrading to a high-efficiency boiler can offer a plethora of benefits. Not only can it significantly reduce your energy bills, but it can also contribute to a greener environment. Here, we delve into the various advantages of making the switch.

Lower energy bills

One of the most compelling reasons to upgrade to a high-efficiency boiler is the potential for significant energy savings. Traditional boilers operate at an efficiency of around 70-80% or less, meaning that a considerable amount of energy is wasted in the form of heat loss.

In contrast, high-efficiency Viessmann boilers can operate at efficiencies of up to 98%, with a minimum of 94%. This translates to less energy consumption and, consequently, lower energy bills. We believe you could save up to £590 a year by upgrading to a more efficient boiler.

Reduced Carbon Footprint

High-efficiency boilers are designed to significantly reduce carbon and greenhouse emissions. Lower energy consumption means less burning of fossil fuels, which in turn results in fewer greenhouse gas emissions. This is crucial in the fight against climate change and for reducing your carbon footprint.

Older less efficient boilers may be 70-80% efficient, or less. They weren’t great when they were built, as new technology and regulations have come along in the past few years, plus boilers can lose efficiency over time.

Increased Comfort

High-efficiency boilers are able to provide a more consistent and even heat distribution throughout your home. This is because they are able to produce heat more efficiently and evenly. As a result, you can expect to enjoy a more comfortable home environment after upgrading to a high-efficiency boiler.

Improved heating control

Modern boilers come with advanced features like programmable thermostats, but you can also add smart controls. These features allow you to customise your heating schedules, optimising comfort while minimising energy use. You can control the temperature of individual rooms, set timers, and even control your heating remotely via smartphone apps.

Improved reliability

High-efficiency boilers are built with the latest technology and high-quality materials, making them more reliable and durable than their traditional counterparts. This means fewer breakdowns and less need for repairs, providing peace of mind and additional cost savings in the long run.

We work closely with Viessmann who have some of the best boilers in the market today. They make a very efficient product and use stainless steel heat exchangers which don’t lose efficiency over time like an aluminium heat exchanger.

Increased value of your home

Upgrading to a high-efficiency boiler can increase the value of your home. This is because high-efficiency boilers are more desirable to potential buyers. As a result, you could expect to get a higher return on your investment when you sell your home.

How much can you save by upgrading to a high-efficiency boiler?

The amount you can save by upgrading to a high-efficiency boiler will depend on a number of factors, including the size of your home, the type of boiler you currently have, and the type of boiler you upgrade to. However, you could expect to save hundreds of pounds per year on your energy bills after upgrading to a high-efficiency boiler.

For example, the Energy Saving Trust estimates that a household with a typical gas boiler could save up to £315 per year on their energy bills by upgrading to a new A-rated condensing boiler.

We’ve had multiple customers tell us that their highly efficient Viessmann boiler is saving them approximately £590 a year! One customer is currently using 3kW a day equalling approx 90p, and it’s running 12 hours a day.

How long does a high-efficiency boiler last?

High-efficiency boilers typically have a lifespan of 10-15 years. This is longer than the lifespan of older, less efficient boilers, which typically have a lifespan of 5-10 years. Often, boilers can last longer than this, but warranties will range from 2 to 12 years. The Viessmann Vitodens range has a 10-12 year warranty depending on the model when serviced by them annually.

Which type of high-efficiency boiler is right for you?

The best type of high-efficiency boiler for you will depend on your individual needs and circumstances. If you are unsure which type of high-efficiency boiler is right for you, you should consult with one of our sales engineers to run through a quick quote and give you the best advice and offers we have available.

How to choose a high-efficiency boiler

When choosing a high-efficiency boiler, there are a few things you should keep in mind:

  • The size of your home

    The size of your home and number of bathrooms will determine the size and type of boiler you need. All the radiators plus any hot water requirements will all add up to the kW boiler you’ll need.

  • The type of fuel you use

    Obviously, if you have gas, you will need a gas boiler and if you have oil, you will need an oil boiler. Oil boiler installers are less numerous than gas safe engineers but Boilerhut has a network of approved installers for all products.

  • Your budget

    Installation of high-efficiency boilers range in price from £1,600 to £3,500 or more depending on your specific property and lifestyle needs.

  • The energy efficiency rating

    The energy efficiency rating of a boiler is measured on a scale of A to G, with A being the most efficient. Boilers should also give you an efficiency percentage too. For example, we know that the Viessmann Vitodens 200-W is 98% efficient. This means that for every £1 spent on fuel 98 pence is spent heating your home or hot water.

  • The warranty

    Most new boilers come with a warranty of at least 5 years. But installations through approved partners, like Boilerhut can get you significantly longer warranties; generally 10 or 12 years depending on the Viessmann model.

How to install a high-efficiency boiler

High-efficiency boilers should only be installed by a qualified heating engineer. This is because the installation process is complex

Every house is different and requires experience to setup correctly and requires specialist knowledge and skills. It’s also important to remember that boilers use fuels, such as natural gas, LPG or oil, all of which are highly flammable.

Carbon monoxide poisoning is a very real and very serious problem that could occur if a boiler is installed incorrectly or not serviced regularly.

Space-saving design

Most new high efficiency boilers are designed to be compact and wall-mounted, freeing up valuable floor space in your home. This is particularly beneficial for smaller homes or apartments where space is at a premium. Combi boilers are even better for space in the home as they don’t require large hot water cylinders in airing cupboards, utility rooms or lofts.

Government incentives

In many countries, including the UK, there are various grants and incentives available for those who choose to install high-efficiency boilers. These incentives can help offset the initial cost of the boiler, making it a more financially viable option.

The main incentive talked about in the UK at the moment is the BUS, or boiler upgrade scheme. This relates to upgrading to an air source heat pump. This is a £7,500 grant that is paid to people once fully installed. However, the grant for air source heat pumps requires strict sign off and additional reports such as a heat-loss report.

Conclusion

Upgrading to a high-efficiency boiler can offer a number of benefits, including lower energy bills, a reduced carbon footprint, increased comfort, improved reliability, and increased value of your home.

If you are considering upgrading your boiler, Boilerhut recommends that you consult with a qualified heating engineer to discuss your individual needs and circumstances.
