Combination vs. System Boilers: Which is Better?

According to Smart Gas Solutions, the difference between a combination boiler and a system boiler lies in how the equipment carries out its primary functions. Combination boilers, also known as combi boilers, can act as both central heating and a water supply and don’t require a storage cylinder; these boilers retrieve water from an internal source and heat it whenever the need arises. 

On the other hand, system boilers require a water tank to function, but because of the extra storage capacity provided by said tank, they are capable of supplying more hot water to the household.

So it’s not so much that one is better than the other; it really depends on your water usage, how big your house is, and your budget.

Combi Boilers: Pros and Cons

Let’s explore the advantages and disadvantages of combi boilers first. Because combi boilers lack storage tanks, they tend to be more compact and use less energy, as they do not have to work to maintain stored water at a consistent temperature. This makes them the more energy-efficient and cost-effective choice. And they don’t take up as much space, either.

However, do note that the output of combi boilers can decrease if tap pressure is too low, which can compound existing functionality issues when demand for hot water is high. Basically, if you have to fight other members of your household for hot water, this probably isn’t the best choice for you. For this reason, Smart Gas Solutions recommends combi boilers for smaller homes with low water usage.

System Boilers: Pros and Cons

Conversely, Smart Gas Solution cites system boilers as a better choice for larger households, as their storage tanks allow them to supply hot water to multiple outlets with virtually no wait times. 

Furthermore, many modern system boilers are compatible with solar panels, which can offset their higher energy requirements. You won’t even notice the costs if you don’t actually have to pay for energy!

That being said, Smart Gas Solutions says that the overall efficiency of a system boiler is influenced by how well the storage tank is insulated, making regular maintenance paramount to keeping the equipment functioning properly. So even if you do have solar panels, you still might have to spend more money on maintaining the boiler anyway.
