How do gas boilers work?

Gas boilers, like boilers that run on other fuel types, are the central piece of equipment in your central heating system. Their main job is to heat water in what is known as a “wet system,” and pump it throughout the house via a series of pipes and radiators.

A continuous supply of natural gas feeds the gas boiler through the gas main connection in the street. When switch on the boiler, gas is set alight and used to heat water via a heat exchanger.

The boiler pumps the heated water to other parts of your house, either to radiators to heat the room, or in the case of conventional or system boilers, to hot water tanks for later use. If you prefer gas combi boilers, then the boiler will warm up the water on demand, and hot water tanks are not needed.

Pros and cons of a gas boiler

There are many advantages to owning a gas boiler.

  • Relatively efficient

Gas is efficient and environmentally friendly compared to other fuel types.

  • Gas main connection

You will not have to store natural gas in the same way you would if you have an oil or LPG boiler.

  • Lower prices

Currently, gas is a much cheaper fuel than electricity.

  • Easy maintenance

Since gas boilers are common, they are relatively easy to maintain and to replace, if the need arises in the future.

However, there are inevitable drawbacks too.

  • Fossil fuel

Even though gas is quite efficient, it is still not a clean, sustainable source of energy.

  • Volatile prices

Since gas price increases are common, your savings might be lower than expected.

  • Installation issues

Without a gas connection, it might take a considerable amount of time and money to connect.

  • Regular maintenance

Additionally, gas boilers require regular servicing to maintain their efficiency.

Running costs of gas boilers

Several factors influence how much you will pay to keep your gas boiler running. These include:

  • Age of your system
  • Your energy and water demand
  • Efficiency of your system
  • Weather
  • Efficiency of your home, namely insulation.

The cost of using gas for your boiler is approximately 4.5p/kWh, compared to 16p/kWh for electricity. Based on the average energy consumption of the UK for heating and hot water (13,500 kWh), the gas and electric heating costs are as follows.

The running cost of gas boilers is approximately £607.50 per year, which is much lower than the £2,160 cost for a fully electric central heating system.

The gas price is still lower than if the Economy 7 tariff is applied. Electric heating costs fall to £1,215, calculated from the lower 9p/kWh for off-peak hours.

Despite the lower efficiency rating compared to electric radiators, gas is one of the cheapest fuels to power your central heating system.
