What is a Combi Boiler?
When it comes to replacing your boiler, there are three main types you need to consider. These include System boilers, Conventional boilers and lastly Combi boilers. With so many choices, it is difficult to know which one is right for you.
The first question is, are you connected to the UK’s gas network? If you are, then you are more likely to opt for a gas boiler. Each type has their own set of advantages best suitable for different properties. The most common type of domestic boiler in the UK are Combi boilers, also known as Combination boilers. They provide instant heat and hot water with no need for water tanks or cylinders.
If you’re still undecided, here is more about why a Combi boiler might work for you.
How does a Combi boiler work?
A Combi boiler is the most popular type of boiler in the UK. The word ‘Combi’ is short for ‘Combination’. The reason for this name is because it’s designed as a single unit with two main functions – hot water and central heating.
Not only do they provide domestic hot water directly to your taps, but also run your central heating. So it eliminates the need for separate storage tanks because a Combi boiler will heat the hot water instantaneously. It works by sensing a flow across a sensor and then heats the domestic hot water through a powerful heat exchanger system.
What is a Heat exchanger?
A heat exchanger is what transfers the vast majority of the heat from the burnt gas to the cold water. It then circulates hot water round to the taps as required. So when a hot tap is turned on, the Combi boiler sends energy to the water, allowing for on-demand hot water at any time of the day.
In regards to the central heating side, your Combi boiler will kick in once the temperature has dropped below your thermostat pre-setting. It will send a signal to your boiler’s expansion tank for hot water to be pumped around your radiators.
Benefits of a Combi boiler
- Save money on energy bills
- No water tank required
- Increased energy efficiency
- On-demand hot water
- Space saving
- Cheap & Quick to install
How are Combi boilers fuelled?
Gas is generally used to fuel combi boilers since most domestic properties have access to gas mains. However, they can also be fuelled by LPG or oil if you’re situated in a rural area where you have no access to gas. Most heating suppliers would advise a combi boiler system as the best option for most average sized residential properties.
How much do Combi boilers cost?
A boiler installation varies depending on how much work you require, the parts needed and professionals you hire. If you are replacing your boiler in the existing place as your old boiler, it will cost around £600 to install a combi boiler. However if you want to install it in any different location, it will cost between £1,500 and £1,800.
