Have you been asking: can a new boiler installation save money? We look at the ways that replacing your older, less efficient boiler can save you money.

How much money could I save with a new boiler?

Replacing the boiler system inside your household or property is an incredibly cost-effective method for adequately reducing your home's current energy costs. 

In the long term, you'll discover that your costs or monthly instalment payments will decrease, and a solid replacement of a more updated, efficient boiler model is the best way to do so.

Boiler Efficiency

Boiler efficiency is deciphered through a percentage rating and is captured through the type of model you have, primarily the age, location in the buildings and various other factors. 

New A-rated boiler systems are at least 90% efficient, and G-rated boilers are approximately 65% efficient for use. 

For energy-efficient boiler options, you should consider investing in condensing gas boilers as these possess a rating of A to A+++, saving you around 30% on annual energy heating or fuel bills. 

Finding the perfect boiler for your household or property is vital to ensure costs remain low and provide quality, efficient heating for your needs. 

1

Combi-boilers

These boilers provide heated water on demand, which is why they are of such good monetary value and energy-efficient for those with smaller homes. It isn't ideal for those with more prominent families or homes due to its lack of hot water storage cylinders.

2

Conventional boilers

These boilers have hot water cylinders directly connected to them, making them perfect for larger households and families requiring lots of water faster.

System boilers

System boiler models combine conventional and combi-boilers, making them entirely efficient without the need to reduce the water supply.

Condensing boilers

Such boilers are perfect for future use, as they condense waste gas and don't waste any energy. They don't sacrifice any efficiency or functionality in their design.

Things to Consider with a New Boiler Installation

If you find that your boiler has aged and worsened in efficiency and therefore needs to be changed, or you're thinking ahead about its future boiler replacement, it's best to begin deciding what type of heating system suits you. 

We highly recommend switching from your current boiler model to low or zero-carbon emission heating systems to reduce your carbon footprint. That way, you ensure you're saving money and being more eco-friendly. 

The UK government plans to gradually reduce carbon emissions to zero within the next few years up to 2050. Fossil fuel heating systems will likely phase out over time to reach these goals, starting an efficient ban from 2025 on gas and oil boilers throughout new buildings and households. 

When choosing the perfect heating system for your property, there are a few instances and aspects to consider.

Fuel type

For those with modern condensing gas boilers with all the right mains gas connections, you'll discover that this boiler system provides some of the lowest running costs for adequate hot water and heating. Average fuel prices for gas fuel tend to be some of the cheapest compared to LPG, house coal, electricity and oil. 

If you're searching for ways to lower your carbon emissions with a form of heating, such as heat pumps, as these are low-carbon and ultimately help reduce your yearly energy costs concerning the fuel you wish to replace it with or the type of system used.

Boiler Type

Oil and gas boilers are either of two types; combi or system boilers. System boilers tend to carry separate hot water cylinders that allow hot water to be stored inside. In contrast, combi boilers typically heat water upon demand and therefore don't require a hot water cylinder.  

It is known that system boilers are usually more efficient at producing heat and hot water as they store it ready; however, one of its downfalls is that heat is typically lost over time from inside the cylinder. 

Combi boiler can become more efficient throughout your property, yet this depends on several factors, for example, the number of people inside the building and installing solar panels for your property. 

A hot water cylinder allows homeowners to store the energy they gain from their solar panel systems. If you cannot have solar panels installed, you may change your decision on the boiler type you wish to purchase and have fitted. 

The perfect boiler is generally determined by the following factors:

The level of hot water usage will impact your decision. Large families tend to use more hot water, making system boilers more suitable. However, smaller households use less water, so a better fit would be combi boilers. The space inside your home or property is paramount to your decision. 

Those with less space should opt for combi boilers as they do not come with any hot water cylinders. Solar water heating compatibility is also significant if you wish to install solar panels for heating. We recommend a system or combi boiler if you wish to implement this. 

Ensure your home is heat pump ready if you wish to install new boilers that include hot water cylinders. Heat pumps require a functioning hot water cylinder to work efficiently.

Boiler Energy Ratings

The age and type of unit you have in your household or property usually determine its boiler efficiency. In their design and use, older boilers are associated with being less efficient than newer, updated ones. 

The industry categorises boiler efficiency through percentages and grading systems, known as the A-G rating. A-rated boilers tend to be around or more than 90% efficient, whereas any G-rated models have approximately 65% efficiency. Between the older and more modern models, these efficiency ratings perfectly display the gulf in performance. 

homes with newly installed boiler units had around 88% efficiency or above

In studies completed in October 2010, professional engineers found that homes with newly installed boiler units had around 88% efficiency or above. 

Efficiency is based on numerous factors; however, one of the most significant is the type of model your professionals installed for you. 

For example, a condensing model that is used by condensing waste gases to use later is more energy efficient than a non-condensing boiler, as these tend to waste more energy. By installing a condensing boiler into your home or property, you can improve boiler efficiency, carbon footprint, and money on your gas bills. 

Annual Energy Savings Breakdown

You'll find that most energy-saving costs are highly dependent on various factors, predominantly the efficiency of the boiler, the fuel used to heat your home, and its overall age can affect the final price. 

The energy rating of your boiler model can also help decipher the energy savings costs you can expect. For example, a higher functioning boiler with an A or B rating will use less energy to heat your home, which will mean you won't have to turn it on at your smart thermostat for such extensive periods whilst the system gears up.

Throughout the UK and England, energy prices are always varied and subject to change by the Energy Savings Trust, which will typically impact your monthly savings. 

When it comes to replacing older boilers, you can find yourself successfully reducing your heating bills through a more high-functioning model; however, it is a massive step to take.  

As mentioned before, the costs you may be expected to pay upfront can be off-putting; however, the potential rewards you can achieve in saving energy and money are attractive factors. 

There are many ways you can improve the energy efficiency inside your home to ensure all wanted heat is kept locked in, whereas unwanted heat during the summertime is kept out. For example, you can utilise blinds, thick or dark curtains or large furniture in the warmer months to block out the sun. When reducing waste and minimalising your heat usage, here's how to go about it: 

One straightforward method that enables you to avoid harmful or unnecessary energy waste is to time your hot water or central heating. Professionals highly recommend setting your heating and hot water to turn on at specific times or different moments throughout the day, and this will encourage your radiators and heaters to heat up far faster. 

Ensure your boiler is turned off whilst you aren't in the house, or pre-emptively turning on your boiler just before you arrive home is far more energy-efficient. That way, your system will be on for less long, as when you return home, it will be nice and warm so that you can switch it off after a shorter period. Ultimately, you'll cut down on energy output, which is more eco-friendly and helps save money. 

The most simple trick includes removing any radiator covers or guards that conceal the heat moving throughout your home. You can close the doors in certain rooms to keep the heat in, help maximise your heat output, save money on energy bills and cut your carbon emissions.
