Boilers are the leading appliances for providing domestic central heating and hot water in U.K.There are different types of boilers available for residential needs. The most common types are combination boilers, system boilers and conventional boilers. However, choosing a boiler with condensing technology is highly recommended. Condensing means, the boiler generates more heat from the amount of oil or gas that is burnt, which is more efficient than a non-condensing boiler. Boilers can be wall-hung or floor-standing.
About Combination Boilers
Combination boilers, otherwise known as combis, provide central heating and instant hot water directly from the mains. They’re compact units easily available in the market. They do not need a separate water storage cylinder or an overhead water tank. As they come as a single unit and take little space, they are ideal for smaller homes. The Combi boilers are extremely easy to install and require less pipework. They are best energy savers as they heat up water instantly. They provide hot water on demand.
Advantages of combi boilers
The combi boilers are very compact and use very little space which makes it ideal for smaller homes.
They supply unlimited hot water instantly from the mains as and when needed. There is no need to wait for the water to warm up.
The Combination boilers are highly efficient when compared to other conventional boilers as it saves energy and cost.
Combi boiler installations are generally cheaper and they are less complex without involving much pipework. This helps in reducing the initial cost.
They involve very little maintenance as they don’t need a separate water storage unit or a water tank.
Disadvantages of combi boilers
The combination boilers are highly dependent on mains pressure and may not support power showers.
The immersion water heater cannot be used as there is no storage space. Hence, no backup option available in case of any breakdown or faults.
Combi boilers are not ideal for larger home as they cannot supply water to multiple outlets at a time. The pressure will be comparatively low in case if the water is used in multiple outlets.
The functional efficiency is affected when the pressure is low at the main itself. So, it is essential to investigate the pressure levels of the mains before installing Combi Boilers.
