Decision: Matching Boiler to Property & People
The core of this choice is how many people need hot water simultaneously. A combi heats water on demand. It's excellent for smaller households (1-3 occupants) with one or perhaps two bathrooms where simultaneous hot water use is rare. For the prevalent 2-up-2-down Victorian terraces in Hindley, with often just one bathroom, a combi is frequently the most practical solution. However, if your property has multiple bathrooms and everyone needs a shower around the same time, a combi will struggle, providing a noticeable drop in flow or temperature.
- Combi: 1-2 bathrooms, 1-3 occupants
- System: 2+ bathrooms, family occupancy
- Combi needs good incoming mains flow
- System buffers weak mains with stored water
