Combi Boiler

Converting to a Combi Boiler

Changing to a combi boiler may seem like a bit of a gamble, especially if you have only owned a system or regular boiler. Yet combi boilers have several unique benefits. Of course, before making the switch, it is important to understand exactly what a combi boiler is and how it functions.

Combi boilers provide hot water and central heating in the same system. These compact boilers heat water directly from the mains, meaning there is no need for a hot water cylinder.


Why Change to a Combi Boiler?

You will find a variety of advantages when making the change to a combi boiler. Firstly, the compact size of these units, means they take up less space than a system or regular boiler. As combi boilers do not need additional water cylinders or tanks, they will easily fit into an airing cupboard or even a kitchen cupboard, providing you with more living space.

Instead of the water being left in a hot water cylinder, hot water is produced on demand. Therefore, combi boilers boast fantastic energy efficiency. This makes combi boilers a cost effective option, helping you to save money on your energy bills.

Is it worth changing to a Combi Boiler?

Converting from a regular boiler to a combi boiler means you can rid your property of clunky water cylinders and tanks. As a combi boiler is guaranteed to save you space, it makes them ideally suited to smaller homes. While water can be heated instantly through the heat exchanger, combi boilers are most effective for homes with low water demand. Although it is possible for these units to provide hot water to bigger properties, the boiler’s efficiency will struggle if there is water coming from multiple sources. This might lead to a reduction in water pressure, disrupting the flow of water in your home.

Although there are large combi boilers available that provide lots of hot water, they can be very inefficient on the heating system side. Some combi boiler manufacturers have found the right balance of providing lots of hot water without sacrificing efficiency, but the maximum they can supply is still only two bathrooms. Therefore, properties with three or more bathrooms, that have a high demand for hot water, benefit from having a boiler with a hot water cylinder.

What is involved in changing to a Combi Boiler?

After evaluating the personal needs of your property, you might just be ready to trade in that old, inefficient heating system for a brand new combi boiler. For this process to take place, you will need the presence of a qualified boiler engineer, who will have to drain the entire heating and hot water system in your home before they can begin.

Your old boiler will then be removed, along with any existing thermostat. You will then be able to say goodbye to those newly, unneeded cylinders and tanks, while then, saying hello to your new boiler. Once your new boiler is installed, the engineer will perform a system flush to get rid of any unwanted debris. A magnetic filter will be implemented in the system, this filter will prevent any undesired materials from entering the system, helping it to run efficiently. With most modern boilers, there is the option for smart thermostats to be installed. This function will allow you to remotely manage your heating schedule and save energy, through the internet. Then, you will be able to register your boiler’s warranty, so any initial breakdowns will be covered. Finally, you will receive a boiler induction, to help you understand the controls and their optimum settings, leaving you fully prepared to get the best out of your new boiler.
