You have three different options to replace your combi boiler. These options are combi boilers, regular boilers (heat only)  and system boilers:

Combi Boilers

Thanks to their compact design, they are generally preferred by those who have to fit a combi boiler in a small space on their property. They can fit in small spaces because they don't require a hot water storage cylinder and a cold-water tank. Because of their design, they are more suitable for small homes and are not an effective choice for large or multi-bathroom homes.

Regular Boilers

Combi boilers are more suitable for small houses, while regular boilers are a choice that can operate very effectively for houses with two bathrooms. However, they come with a cistern tank, which means you are not as flexible as for leaving space as you can do for combi boilers. Besides, the cistern may get frozen if it is exposed to too much cold. On the other hand, they can operate efficiently in homes with low water pressure.

System Boilers
