Cost of New Oil Boiler: Invest in Efficiency with Our Revealing Guide

Are you considering investing in a new oil boiler for your home? Installing a new boiler can be a significant expense, but it’s a worthwhile investment in the long run.

Oil is a popular choice for many households in the UK, providing efficient heating and hot water.

This comprehensive guide will explore the cost of new oil boilers, including installation, running costs, and benefits. By the end, you’ll understand the expenses involved and why upgrading to an oil boiler is smart.

1. Introduction to Oil Boilers

Oil boilers are a popular choice for homeowners in the UK who are not connected to the gas grid. They provide efficient heating and water, making them an excellent alternative to gas boilers.

Approximately 6% of UK households use oil boilers for central heating systems. These boilers are particularly common in rural and remote areas with limited access to the gas grid.

With an oil boiler, you can enjoy a reliable and consistent heat and water supply throughout the year.

Oil boilers are known for their efficiency, and modern models are designed to maximize energy savings. Upgrading to a new oil boiler can reduce bills and decrease carbon footprint.

2. Factors Affecting the Cost of Oil Boilers

The cost of installing an oil boiler can vary depending on several factors. Understanding these factors will help you estimate the expenses and make an informed decision about your investment.

Size of Property

The size of your property plays a crucial role in determining the size and output of the oil boiler you need.

Larger properties with more rooms and radiators will require a more powerful boiler to meet the heating and water demands.

On the other hand, smaller properties will require a smaller boiler. The size of the boiler will impact the overall cost, with larger boilers generally being more expensive.

Type of Boiler

Different types of oil boilers are available, including combo boilers, system-type boilers, and conventional boilers.

Each type has its own features and benefits, and the cost can vary accordingly. Combo boilers are compact and provide heating and water on demand.

System-type boilers store water in a cylinder, making them suitable for larger households. Conventional boilers use a cold water tank and a water cylinder.

The type of boiler you choose will affect the cost of installation.

Number of Radiators

The number of radiators in your property also influences the size and output of the oil boiler. A higher number of radiators will require a more powerful boiler to ensure efficient heating throughout the property.

The new boiler installation cost will increase with the number of radiators it needs to support.

Location

The location of your property can impact the cost of installing an oil boiler. Areas with higher living costs, such as London and the southeast, may have higher installation costs.

In contrast, remote and rural areas may require additional charges for installation due to accessibility issues.

The location will also determine the availability and cost of oil supply in your area.

3. Types of Oil Boilers

Before diving into the cost of installing an oil boiler, it’s essential to understand the different types available.

Each type has its own features and benefits, catering to different household needs. Let’s explore the three main types of oil boilers.

Combination Oil Boilers

Also known as combi boilers, they are a popular choice for smaller households.

These boilers provide heating and water on demand, eliminating the need for a separate water cylinder or storage tank.

Combi boilers are compact and space-saving, making them suitable for properties with limited space. They are energy-efficient and offer fast water delivery.

However, they may not be suitable for larger households with high water demands.

System Oil Boilers

System oil boilers work with a hot water cylinder to store and deliver throughout the property.

They are suitable for larger households with higher water demands. System style boilers are more efficient than conventional boilers as they eliminate the need for a cold water tank in the loft.

They provide a constant supply of water to multiple outlets simultaneously.

Conventional Oil Boilers

Conventional boilers, also known as heat-only or regular boilers, require a separate water cylinder and a cold water storage tank.

These boilers are suitable for properties with older heating systems and multiple bathrooms. Conventional boilers are often found in traditional properties and provide a reliable and efficient heating solution.

However, they require more space for installation and may not be as energy-efficient as new combi boilers or system boilers.

4. Cost of Installing an Oil Boiler

Now that we understand boilers well and their types, let’s explore the cost of installing a new oil boiler.

The cost can vary depending on multiple factors, including the property size, type of boiler, and additional requirements.

By understanding the installation costs, you can budget effectively and make an informed decision.

Oil Boiler Installation Costs

The installation costs of an oil boiler can range from £1,500 to £6,500, depending on various factors.

The size of the property and the type of boiler you choose will impact the overall cost.

Larger properties with more radiators require a more powerful boiler, increasing the installation cost.

Likewise, the type of boiler you choose, such as a combi boiler, system, or conventional boiler, will affect the installation cost.

To give you an idea of the installation costs, let’s look at some estimates:
