Heat Pumps vs. Traditional Heating Methods

heat pumps vs traditional heating methods

Are you considering a new heating system but unsure whether to opt for a heat pump or stick with traditional methods like gas or oil boilers? As energy costs climb and environmental awareness grows, the choice between these options becomes increasingly important. 

In this article, we’ll explore how heat pumps stack up against conventional heating methods in terms of efficiency, cost, and environmental impact. Whether you’re looking to reduce your carbon footprint or just curious about the latest in home heating technology, we’ll provide you with all the details you need to make an informed decision that suits your home and lifestyle.

Are heat pumps the right solution for your needs? Let’s find out.

Traditional heating methods

Central heating became standard in homes during the 1970s and 1980s. Before that, people relied on fireplaces and left their stoves on to produce heat. 

From traditional combustion systems to more modern combi boilers and electric radiators, these systems have their benefits but also contribute to environmental damage. 

According to the National Audit Office, 18% of the UK’s greenhouse gas emissions come from heating homes, leading many people to seek alternatives. 

Let’s look at which traditional heating methods offer the most efficiency. 

Gas central heating 

Gas central heating is a common method in the UK, but not all homes have it. Water heats through the gas-fired boiler, which then goes into radiators and pipes to ensure households have heat and hot water. 

Newer gas combi boilers work differently by heating taps on demand instead of through a hot water tank. 


  • Larger properties can take advantage of gas central heating, as it can heat multiple rooms at once. 
  • Gas remains on during power cuts, making it a convenient solution. 
  • Moving from a traditional gas boiler to a combi solution is simple. 


  • Gas central heating costs can mount up, with Ofgem estimating the average annual cost per household at £542. However, many households pay much more. 
  • Global supply levels influence UK gas prices. If supplies are low, it becomes more expensive. 
  • Gas central heating relies on fossil fuels, so it’s not a clean energy source. 

Electric heating systems 

Some UK properties aren’t connected to the gas grid and rely on electric heating systems. 

Storage heaters activate at night when electricity costs are lowest. Ceramic bricks with heat-retention qualities can disperse heat during the day and are cost-effective, but turning them on during peak hours can be expensive. 

Immersion heaters use metal coils and loops in a hot water cylinder to distribute heat around the property. These heating systems are popular for houses without a gas supply. 


  • Immersion heaters can be cost-effective when properly insulated. 
  • Electric heating systems are more accessible for people in flats or those without a gas supply. 
  • Thermostats can control the electric heating, ensuring it doesn’t stay longer than needed. 


  • Heating a home with electricity is often more expensive than gas. 
  • Electricity costs more in the daytime – especially if you use the heaters during peak hours. 
  • Larger homes might struggle to maintain a consistent temperature with electric heaters. 

Oil heating 

Oil heating isn’t as popular as gas or electric systems, but just over one million UK households use it. It works similarly to gas central heating, but the boiler heats the oil, which then goes into the radiators. 

Instead of relying on the grid, oil is delivered to your home and placed in an outside tank, potentially reducing costs. However, running costs can be high. 


  • Households can save money by buying fuel when the prices fall. 
  • Oil can offer better efficiency when used with modern boilers. 


  • Oil prices depend on global supply and political conflicts. 
  • The initial installation and purchase of fuel can be expensive. 
  • Oil is still a non-renewable source of energy. 

Heat pumps

Heat pumps are making a lasting impression on homeowners who want to live more sustainably without compromising comfort. They use renewable energy sources to generate power, promising to reduce our reliance on fossil fuels. 

There are three types of heat pumps available, with air-source pumps being the most common. Let’s examine each in more detail. 

Air-source heat pumps 

Air-source heat pumps use outside units that extract heat from the air, which a heat exchanger transfers into a property. The heat they generate can provide hot water and warm radiators, resulting in a warmer property. 


  • Most homes can use air-source heat pumps, as they’re more accessible than water or ground-source pumps. 
  • The pumps don’t use any fossil fuels and are clean energy sources. 
  • Households can save money on their bills by not relying on the power grid. 


  • Air-source heat pumps can be more expensive initially but result in lower energy bills. 
  • Other forms of heat pumps offer more consistency. 

Water and ground-source heat pumps 

Ground-source heat pumps generate heat using the earth’s consistent temperature, while water-source heat pumps generate energy from lakes, ponds, or rivers. Both of these options are more consistent, but they also require expert installation. 

Installing a ground-source heat pump means digging at least one metre underground and laying pipes, while properties that install water-source heat pumps must have access to a pond, river or lake. 


  • Ground and water-source heat pumps can offer consistent performances. 
  • The pumps generate clean energy, making them more sustainable. 
  • Installing one can save you hundreds each year. 


  • Properties without an available water source or small gardens won’t be able to install ground or water-source pumps.
  • The installation process can take time as they’re more complex than air-source heat pumps. 

The bottom line 

Heat pumps will become a go-to solution as the UK moves away from its reliance on fossil fuels. Their ability to generate clean energy can make a significant difference to the environment while helping each household reduce its emissions. 

Yes, they can cost more to install initially, but government grants and Green Home Loans are available. 

Our customers can also take advantage of heating and solar plans that split the cost of heat pumps into monthly instalments and come with regular services and free repairs.
