What does a combi boiler do?
The combi boiler activates when the hot water tap is turned on in your home. When the water is flowing from the mains into your tap, it will pass through a sensor telling the boiler to burn gas or oil. Inside the combi boiler, a heat exchanger heats up, so water flows across it and it heats up before it reaches the tap.
The boiler’s heating function functions in the same way as before, providing hot-water to your radiators.
Pros and cons of combi boilers
Combi boilers have become more popular in the UK due to their many advantages. While these boilers may not suit every home, it is best to get the guidance of a Gas Safe registered engineer. This is our list of combi boiler pros and cons.
A combi boiler has many advantages
Combi boilers are small and compact – Combi boilers work well in smaller properties with little or no loft space. The combi boiler is safe from freezing of loft pipework. You can even place the combi boiler inside an existing cupboard.
It is possible to save money by installing fewer pipes. A combi boiler heats the water you use, meaning less energy is wasted, which could result in lower energy bills.
Convenient – Hot water is delivered on-demand using combi boilers. This could be very useful if you need to use the shower. You don’t need an additional pump because hot-water is delivered at mains pressure.
Combi boilers are energy-efficient and designed to reduce energy consumption. This can be increased if the combi boiler is paired with additional energy-saving appliances like a smart thermostat. You could have full control over your heating system by pairing it with smart technology.
Advantages and disadvantages of a combi boiler
It is not suitable for homes that have high hot-water needs. Combi boilers can provide hot water only on demand. This means they won’t work well when more than one hot faucet is on at the same time. A combi boiler might not work well if you have several people who want to shower each morning. You have options. There is an electric shower, a mains booster, or accumulator tank.
No Immersion Heating – Immersion heating is often provided by Worcester Bosch boiler installers Bridgwater in order to provide an alternative for a boiler that breaks down. These back-up water heaters are not compatible with combi boilers. This means that in the event of a break-down, you will be without heating or hot-water for the duration of your repair appointment.
