Sharing is caring!

Are you shopping around for a new boiler? Choosing which to buy can be confusing. For example, some prefer the conventional boilers while some like the combi boilers. But what is the difference between the two?

A combination boiler is a combination of heating water and a central heating system in one unit. Combi boilers operate by instantly heating water without needing an external storage tank to store the hot water.

On the other hand, a conventional boiler is a traditional heat-only boiler. Once turned on, the boiler heats the water consistently and stores it in separate storage. Conventional boilers often have two tanks to store both cold and hot water. The cold water is supplied to heat the boiler, and the resulting hot water will be stored.

Battle of the Boilers: Combi vs Conventional?

So which is better between the combi vs conventional boiler? It’s good to consider the following criteria before choosing which has the edge over the other.

Energy efficiency

Combi boilers are highly efficient, while conventional boilers are less efficient.

Cost

Combi boilers can be easily installed. You can easily find parts for it, too. Also, they don’t require much labour for installation. Unlike conventional boilers that are complicated to install and have different parts and pipes, combi boilers are relatively simpler. Overall, convention boilers can be time-consuming and would need more people to install. Cost can also be managed better with the help of boiler financing. If you don’t want to spend a large amount of money upfront, you can finance your boiler here.

Storage space

Combi boilers don’t require much space in the house, unlike conventional boilers that need big space for the two tanks.

Use

Combi boilers can only accommodate one water flow at a time, while conventional can support more multiple simultaneously.

Heating time

When heating water, combi boilers tend to heat water instantly, while conventional boilers need at least 30 minutes for the water to be completely hot.

Breakdown

In case the boiler breaks down, combi boilers stop, which means there is no hot water supply and heating in the house available. On the other hand, conventional boilers can only supply hot water but not heat the house.

Water supply

For combi boilers, the water can be supplied from the main source without much work while in conventional boilers, you’d need a tank to store the water needed.

 

Which One Should You Go For?

It depends.

If you have a big space, you can go for conventional boilers. But if you want to save space, then try combi boilers. If you have an existing heating system in your home, it’s better to use the same to avoid additional costs for upgrades.

Also, another to consider is the demand for hot water needed and the number of bathrooms available. When there are more bathrooms and demand for hot water simultaneously, it is better to use the conventional boiler.

Generally, combi boilers are condensed, easy to install, and a quick hot water supplier. This makes it ideal for small homes and people with tight budgets. On the other hand, conventional boilers are big, space-consuming, complicated to install boilers that large households can use.
