Living in the UK, we are all too familiar with the importance of boilers during the cold winter. Boilers provide us with hot water and heating. Still, suppose yours is not performing optimally, resulting in high energy bills and inefficient hot water and heating. 

In that case, it may be time to invest in a new boiler with a high-efficiency rating. When making this crucial decision, you will need to consider the type of Boiler, the wattage size, and the space available in your home as a boiler can last up to 10-15 years, and rushing into your decision can prove to be very costly. 

This article will guide how to choose the right Boiler for your home, ensuring you get the best product in terms of performance, price value, and longevity.

Consider the type of boilers that are available in the market!

Choosing the correct type of Boiler is essential, as it will provide reliable service for years to come. If you don’t make the proper selection, you may be stuck with a flawed system for a long time. Generally, there are three central boilers available: Regular, System, and Combi. Each has unique features and benefits, so let’s take a closer look.

Regular Boilers

A regular Boiler, also known as a heat-only or conventional boiler, simultaneously provides heating and hot water to multiple taps and bathrooms. It consists of a cold-water storage tank and a hot-water storage tank, making it a traditional way to provide your home with an uninterrupted heating and hot water supply. 

The operation involves taking water from the mains into the cold-water storage tank, which is generally stored in your loft, and transferring it to the hot water tank, which is usually located in your airing cupboard. Additionally, it consists of a feed expansion tank that helps maintain water levels in case of lost water due to leakage or evaporation. The cost of a Regular Boiler ranges from £730- £2300.

System Boilers

A system Boiler is a type of Boiler that provides hot water and heating to multiple bathrooms and taps simultaneously. It may look like a Regular boiler, but the main difference is that a System Boiler only requires a hot water tank, and everything else is built internally, leaving you with plenty of space. 

In terms of operation, it heats water via a heat exchanger, which is then stored in the hot water tank and distributed to your taps, showers, and radiators. The cost of a System Boiler ranges from £1100- £3500.

Combi Boilers

A combi boiler is the most popular and space-efficient Boiler, providing hot water on demand when needed. Around 80% of homes in the UK have Combi Boiler installed. Their popularity is because they draw water directly from the mains, eliminating the need for hot and cold-water storage tanks. 

This makes them ideal for those looking to save space and energy in their home. The cost of a Combi Boiler ranges from £625 – £6188, depending upon the brand and the wattage output.

Weigh in the advantages and disadvantages of different types of boilers.

Now that you are familiar with the various types of boilers and how they operate, it is important to consider the pros and cons of each option before making a purchase. Doing so will help you make an informed decision that best suits your needs.

Regular Boiler
Advantages	Disadvantages
Regular Boiler provides hot water at multiple taps, showers, and bathrooms. The process of installing a Regular Boiler is relatively simple. It is also compatible with immersion heaters consisting of a hot water tank. Regular boilers are not highly dependent on the main pressure.	A regular Boiler requires ample space to store two separate water storage tanks. Once your tank runs out of hot water, you will need to wait for the water to heat up again, which might take some time. The stored water in the hot water tank can lose its heat if not used for a few hours.

System Boiler
Advantages	Disadvantages
System Boiler provides hot water at multiple taps, showers, and bathrooms. System Boilers occupy less space as they consist only of hot water tanks. They are also compatible with immersion heaters. Compatible with solar panels.	Occupies more space as compared to Combi Boilers. Hot water is not instant as compared to Combi Boilers. Complex Installation process. Water might get wasted if you don’t use all the water in the tank, as it will lose its heat.

Combi Boiler
Advantages	Disadvantages
Get instantaneous hot water on demand. Its compact design makes it easy to install. Its condensing technology saves you money on energy bills. Compatible with a variety of fuel options.	It highly depends upon the mains water pressure. Not suitable for larger homes with heavy demand for hot water and heating. It is not compatible with power showers.

Choose the fuel type! 

After weighing the advantages and disadvantages of 3 different boilers, it is time to choose the fuel type. The options you will have been following:

1. Gas 

Due to its affordability, gas is the most popular and widely used fuel for heating boilers. According to UK boiler statistics, in 2023, around 23 million homes in the UK have a gas boiler. However, the UK government has implemented regulatory policies to limit gas usage to reduce environmental carbon dioxide emissions. 

You can easily access gas by speaking to your local gas network provider. Additionally, modern gas boilers are much more energy-efficient than older models, with some reaching up to 90% efficiency. Therefore, switching to a more up-to-date system may be the best option for your needs.

1. Oil 

Oil is another common fuel, though not as popular as gas. It is also relatively inexpensive and a great alternative if you are not connected to a gas grid network. However, before choosing oil as a fuel type, you should consider that you will need an external storage tank to fill it with oil, and when it runs out, you will need to get it refilled, which can take some time. 

Additionally, oil has a higher intensity of releasing CO2 into the environment. Nevertheless, if you are considering oil as your fuel type for heating and hot water, you can rest assured that 865,940 households already use oil to heat their homes.

1. LPG 

LPG is a more expensive fuel option than gas and oil but emits around 12% fewer CO2 emissions. It is an efficient choice, as it requires less storage space, and its maintenance costs are cheaper than oil. Despite its higher cost, there are fewer qualified engineers available for LPG. 

However, if you are not connected to a gas network and oil is your only option, then LPG is worth considering.

1. Electric 

Electricity is a fuel type gaining considerable popularity due to its lower carbon dioxide emissions. It is more expensive than oil and gas but has fewer maintenance costs and is safer to operate. If you have solar panels, electricity is the best fuel option, as you can offset a significant portion of the cost. 

Therefore, electricity is the best option if you are willing to bear the hefty price tag to reduce your carbon footprint.

1. Biomass

Biomass fuels are an effective and cost-efficient fuel type for boilers that can generate renewable energy while reducing emissions. Biomass fuels are derived from organic materials, including wood, agricultural waste, and other by-products of forestry or farming industries. 

These biomass fuels can be burned in a boiler to produce heat energy used in many industrial applications such as food processing, paper production, and even small-scale power generation. Burning biomass creates fewer carbon dioxide emissions than traditional fossil fuels like coal and natural gas due to the lower carbon content of organic materials used as fuel sources. 

Additionally, fuel supply for biomass is abundant and relatively low cost due to the availability of forests, farms, and agricultural waste. The sustainability of biomass utilization makes it very attractive among those looking for solutions to reduce environmental impact while still being cost-effective in the long run.

Other factors to consider:

Now you know the type of boilers that are available as well as the fuel type, but still, there are a few factors to consider before buying a boiler:

Energy Prices:

Knowing the current and future energy prices is essential, as the UK government has implemented the Energy Price Guarantee (EPG) to protect customers from rising gas and electricity costs by capping the amount suppliers can charge per unit of energy used. 

However, it is vital to remember that energy prices may still increase in 2023, regardless of how much energy you conserve. Selecting a boiler with a high-efficiency rating is recommended to ensure you are saving on your energy bills.

Budget:

When budgeting for a new boiler, it is important to consider the potential long-term savings associated with installing a high-efficiency boiler. Though investing in an efficient model may have a higher initial cost, the return on investment can be significant over time due to reduced energy and maintenance costs. Consider including additional costs such as installation, insulation, and venting materials when pricing different units. 

Additionally, research local incentives or rebates that may reduce total investment, including those from the local utility or government agencies. With proper planning and research, one can purchase the right equipment to fit their current needs while minimizing overall costs over time.

Usage and Household size:

Your usage is critical, as the three different types of boilers mentioned above will be practical depending on your use. To make it simple, if you have a small household with one or two bathrooms and two to four people requiring hot water and heating, then a Combi Boiler is the ideal choice. 

On the other hand, if you have a new central heating system in a new home with three to four bathrooms and five to seven people requiring hot water and heating, then a System or Regular Boiler is the best option.

Warranty Period

When purchasing a boiler, it is crucial to assess the quality of the warranty period offered by the specific model. Look for warranties that are comprehensive and offer protection from defects and malfunctions in both parts and labour over the lifetime of the warranty period. Generally, warranties can vary from 1-5 years, depending on product type and manufacturer. 

Boilers usually have long periods of coverage due to their high cost of repairs or replacement if something goes wrong. More expensive models may come with a more extended warranty, providing peace of mind. It is essential to read the terms and conditions carefully to understand all allowable exclusions, as well as what service or repair costs will need to be paid by you should something go wrong.

Cost of the Boiler

The cost of a boiler can vary depending on the type and size required. Generally, boilers are priced according to their energy efficiency rating, ranging from 90-95% for high-efficiency models to lower ratings for standard models. In addition, factors such as fuel type (natural gas, oil, or electric), BTU output and model features may affect boiler cost. 

Professional installation is recommended for best results, which can add anywhere from £500-£2,000 to the total cost depending on complexity and other geographic factors. Be sure to consult with a professional to determine the boiler cost and any additional installation costs that may be incurred.
