With increasing energy-consciousness, the decision to invest in a new boiler can be both a practical and financially savvy one. 

In this article, we’ll walk you through the considerations that prompt the need for a boiler upgrade, examine various boiler types, dissect the associated costs, and uncover the ways in which a new boiler can save you money. 

Moreover, we’ll provide valuable insights on calculating potential savings, which we hope will help you to make a correct informed decision. 

Is it Time For a New Boiler?

If your current boiler is nearing the end of its lifespan, it’s worth considering a boiler replacement. Older boilers are often less energy-efficient and more prone to breakdowns. If you frequently call for repairs, the costs can increase over time. Investing in a modern boiler might be more cost-effective in the long run.

A drop in your boiler’s efficiency can lead to higher energy bills. If you notice increased heating energy costs despite consistent usage, you might think, “will a new boiler save me money?”

Types of boilers

Let’s cover some of the most popular types of boilers:

Combi Boilers

Combination or combi boilers provide hot water and central heating without needing a separate water tank. They are space-efficient and provide instant hot water.

System Boilers

System boilers work with a hot water cylinder but don’t require a water tank in the loft. They are suitable for homes with multiple bathrooms and high hot water demand.

Regular Boilers

Also known as conventional or traditional boilers, these require a hot water cylinder and a cold-water storage tank. They are ideal for older homes with an existing central heating system.

The Costs of Getting a New Boiler

The costs associated with replacing your current boiler are divided into two sections. There are the initial and installation costs. This section will cover these costs in more detail and some long-term savings considerations.

Initial Costs

The upfront cost of the boiler unit itself is a significant consideration. Different types of boilers (combi, system, conventional) and brands come with varying price ranges based on features and boiler efficiency. 

Depending on the type of boiler, you might need to invest in additional equipment, such as a hot water cylinder or a water tank, adding to the initial expenses. 

Proper installation requires quality piping and fittings, contributing to initial costs. Ensuring the right materials are used is crucial for safety and efficiency.

Installation Costs

Hiring a certified home heating engineer for boiler installation is essential. Labour costs can vary based on the installation’s complexity and your property’s location. 

Depending on local regulations, if you’re replacing an old boiler, there might be costs associated with its removal and disposal. Installing a new boiler might require additional components such as thermostats, controls, and flue systems. These add-ons contribute to the overall installation cost.

Long-Term Savings Consideration

While the initial costs can seem high, investing in a more energy-efficient boiler can result in long-term savings on your energy bills.  New boilers typically come with warranties that cover repairs for a certain period, reducing the need for immediate additional expenses.

How Can a New Boiler Save Me Money?

There are many ways that a new boiler can save you money. In this section, we will cover some of the most important ones.

Efficiency Savings

New boilers are designed with advanced technology to make your home more energy efficient. They use less fuel to produce the same heat, reducing energy consumption and lowering utility bills. Many new boilers are condensing boilers, which recover heat from exhaust gases. This significantly improves efficiency and reduces energy wastage. 

New boilers come with energy efficiency ratings. Choosing a boiler with a high rating ensures you’re getting the most energy-efficient option, leading to substantial long-term savings.

Maintenance Savings

New boilers are less likely to break down or require frequent repairs, reducing maintenance costs. Most new boilers come with warranties that cover repair costs for a specific period. This eliminates unexpected repair expenses during the warranty period.

Government Schemes/Grants

Many governments offer incentives for upgrading to energy-efficient boilers as part of environmental conservation efforts. These incentives can significantly lower the cost of purchasing and installing a new boiler.

Various grants and subsidies are available for homeowners to encourage the adoption of energy-efficient heating systems. These financial aids can offset the initial investment of a new boiler. In some regions, renewable energy incentives promote using boilers powered by sustainable energy sources like solar panels or biomass.

How to Calculate Potential Savings from a New Boiler

Let’s take a better look at how to calculate the savings that might come from getting a new boiler.


Assessing Energy Efficiency

Calculate the Annual Fuel Utilisation Efficiency (AFUE) of your existing boiler. This indicates how efficiently it converts fuel into heat. Explore the AFUE ratings of modern boilers. High-efficiency condensing boilers often have AFUE ratings above 90%, meaning less energy waste.

Estimating Fuel Consumption

Collect data on your current fuel consumption. This could be in gallons of oil, cubic metres of natural gas, or other relevant units. Using the new boiler’s AFUE rating, estimate your potential fuel consumption. Divide the current consumption by the old AFUE and multiply by the new AFUE.

Estimating Cost Savings

Know the current cost per unit of your fuel (e.g., cost per gallon of oil or per cubic metre of gas). Multiply the current consumption by the current cost per unit to get your current heating costs. Repeat for potential consumption and cost per unit. The difference between potential and current costs represents your potential annual savings.


If your boiler shows signs of ageing, then what are you waiting for? Replace it as soon as possible and get all the benefits we mentioned. 

The text highlights that newer boilers are more energy-efficient, reducing energy consumption and utility heating bills. 

While the initial investment may seem significant, long-term savings through reduced maintenance, improved efficiency, and potential government incentives make it a cost-effective choice. 

You can make an informed decision by assessing your existing boiler’s efficiency, estimating fuel consumption, and calculating potential cost savings. Upgrading to a new boiler enhances your home’s efficiency and contributes to environmental sustainability through reduced energy wastage.
