Picture this – it’s a cold winter day. You’ve cuddled up on the sofa with a soft blanket and a nice cup of tea, enjoying the warmth inside your home. You probably have your central heating to thank for that comfort and protection from the chill outside. Maybe you’re just wondering how it all works, or maybe you want to know what types of central heating systems there are. Well, read on! This article is for you.

If that sounds like you – you’re in luck! This article has the answers.

Wet Heating Systems

Wet central heating systems are the most popular type in the UK, used by over 90% of households. This kind of system uses a fuel-burning boiler to heat up water. The hot water travels through the house via a network of pipes, either buried under the floors or passing through the walls, reaching the radiators. Once it has passed through each one, the water makes its way back to the boiler to be reheated, and the cycle continues. This gives your radiators the heat they need to warm your house up and provides your taps and showers with hot water.

With wet central heating, you will probably have a standard or a combination boiler, the latter being more popular. While standard boilers require a hot water cylinder for storage, combi boilers provide instant hot water and are considered more efficient.

There are several types of fuel that may power your boiler: gas, oil, LPG, or solid fuel.

Gas

Gas central heating is undoubtedly the most common type. Its price and convenience, along with the efficiency of modern boilers, makes it the top choice for many households. With this kind, natural gas is transported to your boiler through the gas distribution network. The boiler then burns that fuel to heat up the water that travels through the system.

However, not all homes can benefit from this type of central heating. Many households aren’t connected to the gas grid. Installing a new heating system from scratch can be costly and disruptive, so many choose an alternative method of heating.

Pros

  • Cheaper than other types
  • Upgrading your boiler is simple
  • Gas does not need to be stored
  • Modern boilers are efficient

Cons

  • You need to be connected to the gas grid
  • Installing a gas central heating system can be disruptive
  • Gas is not a clean source of energy
  • Prices are on the rise

Oil

For many families that can’t get connected to the gas grid, heating oil can be an alternative. It works in a similar way to natural gas, but the fuel itself gets delivered to your property in a truck. This means oil needs to be stored on site. To do that, you may need to rent or buy an oil storage tank from your supplier. Oil central heating systems are generally cheaper to run, the price being close to that of gas.

Pros

  • Cheaper than most types
  • Efficient
  • Replacing your boiler is easy
  • Good alternative if you don’t have a gas grid connection

Cons

  • Fuel needs to be stored on site
  • You may need to rent or buy a storage tank
  • Prices fluctuate often
  • The storage tank needs annual servicing
  • Oil is not a clean source of energy

LPG

LPG (Liquid Petroleum Gas) is another alternative to mains gas. It shares some similarities with oil heating systems, in that the fuel is delivered to you and needs to be stored on site. One significant difference is the price of running an LPG system. The costs are much higher than those of natural gas or oil, closer to those of electric heaters.

Pros

  • Efficient
  • Good alternative to mains gas
  • Replacing your boiler is easy

Cons

  • Fuel needs to be stored on-site
  • You may need to rent or buy a storage tank
  • More expensive than other types
  • LPG is not a clean source of energy

Solid Fuel

This refers to boilers that burn coal or biomass (for example, wood chips). These types often use back boilers, which are now dated and rarely used. While some say that biomass burning systems are sustainable, the emissions can be polluting and therefore are not considered a clean source of heat. Solid fuel burners also require cleaning out daily, which can be a hassle.

Electric Storage Heaters

This is perhaps the second most common type of central heating. Storage heaters are wired into the house’s electric system. They use the off-peak electricity at night to warm up heat-retaining bricks, placed inside the heaters. The bricks store that heat and release it during the day. Most storage heaters can be used as standard ones, too, and can be switched on at will. Since they use night electricity on the Economy 7 or 10 tariffs, the energy usage bills are not as high as if you were to use the regular kind.

Installing such a heating system is cheaper and simpler than the wet kind, since they call for much less effort and no pipework. However, the cost of running electric central heating can be three to four times higher than that of gas.

Pros

  • Easier and less disruptive to install
  • No piping required
  • Mains electricity is widely available
  • Storage heaters can be used as regular ones as well

Cons

  • A lot more expensive to run
  • Daytime rates on Economy 7 and 10 tariffs are higher than on single-rate
  • Increase in gas prices reflects on electricity cost

Warm Air Systems

This type of central heating used to be common in the 70s and 80s, but has lost popularity in homes in recent years. It is still commonly used in commercial buildings in the UK. With warm air systems, the boiler heats up air and distributes it around the property through ducts and vents. These kinds of systems can be either gas or electric powered.

Pros

  • Commonly used as a cooling system as well
  • Can be cheaper to run
  • Heats up your home quickly
  • Efficient

Cons

  • Many systems do not heat water
  • Installation prices can be higher
  • Retrofitting ducts into your home can be difficult
  • Moving air can be an issue for people with allergies

District Heating Systems

District central heating is only available in certain areas of the UK. In these places, properties get their hot water and heat from a centralised heating source, such as a fuel burning plant. Think of it as one big boiler that supplies the hot water to your neighbourhood. The water gets transported around the houses through insulated pipes that run under the streets. This type of heating has the advantage of being low maintenance, as you don’t need to service or repair a boiler in your own home.

However, installing it can be costly. Another downside is that the properties must be close together and can’t be branched out at great distances.

Pros

  • Pay for what you use
  • More efficient
  • Low maintenance

Cons

  • Heat can leak if pipe insulation is faulty
  • Only available in certain areas
  • Expensive to install for the first time
  • Properties must be close together
