Replacing a boiler is a big decision, and the type you choose affects your hot water, your energy bills, and how much space you give up. The two most common choices for homes in Inverness are combi and system boilers. Here’s how to decide.
What is a combi boiler?
A combination (combi) boiler heats water on demand, straight from the mains, without needing a separate hot water cylinder or cold water tank. Turn on a tap and hot water arrives within seconds.
- Space-saving, no cylinder or loft tank required
- Hot water on demand, with no waiting for a tank to heat
- Generally cheaper and quicker to install
- Ideal for flats and smaller homes with one bathroom
What is a system boiler?
A system boiler works with a separate hot water cylinder, storing a large volume of hot water ready to use. This means it can supply several taps and showers at once without a drop in pressure.
- Strong performance with multiple bathrooms
- Hot water to several outlets at the same time
- Compatible with solar hot water systems
- Better suited to larger family homes
Which should you choose?
As a rule of thumb: if you live in a smaller home or flat with one bathroom, a combi is usually the most efficient and cost-effective choice. If you have a larger property with two or more bathrooms and a busy household where several people need hot water at once, a system boiler will cope far better.
Mains water pressure matters too. Some rural Highland properties have lower pressure, which can affect how well a combi performs, something worth checking before you decide.
