This space-saving advantage makes them ideal for properties with limited space, while their efficient operation can help reduce energy costs.

System Boilers

System boilers are designed for homes with higher hot water demands, typically those with more than one bathroom. They use a hot water cylinder, which allows them to supply multiple outlets simultaneously without losing pressure. This makes them suitable for medium to large homes where the demand for hot water is substantial, ensuring that showers, taps, and appliances can operate concurrently.

Conventional Boilers

Conventional boilers, also known as regular or traditional boilers, are most suitable for larger families with significant hot water requirements. They utilise both a hot water cylinder and a cold water storage tank, providing a reliable supply of hot water to multiple bathrooms and taps at once. This type of boiler is advantageous in larger properties with existing traditional heating systems.

Oil and Electric Boilers

Oil boilers are a common choice in areas without access to natural gas, offering a reliable heating solution. They are often used in rural settings where oil is easily available. Electric boilers, on the other hand, are ideal for homes looking for a cleaner and quieter alternative, particularly where gas supply is not feasible. They are versatile and can fit into spaces where other boilers might not, though they can be more costly to operate due to electricity prices.
