Understanding Heat Only Boilers and Their Benefits
Heat only boilers, often called regular or conventional boilers, are designed to work with a separate hot water cylinder and cold water storage tank, making them suitable for properties with multiple bathrooms or high hot water demand. These boilers provide reliable central heating and stored hot water, commonly used in larger homes and traditional heating systems. They are frequently installed alongside system boilers, boiler flues, and heating controls to create a complete, efficient setup.
These boilers operate by heating water that circulates through radiators and a cylinder, ensuring a steady supply for taps and showers. Most models are compatible with open vented or sealed systems and meet modern standards such as ErP A-rated efficiency. They can work with smart thermostats and often include features like automatic pressure management and rear piping connections for easier installation.
Practical benefits include the ability to supply hot water to several outlets simultaneously without pressure drops, making them ideal for homes with multiple bathrooms. Their compatibility with older radiator systems reduces the need for major upgrades, and the separate storage system means hot water remains available even during boiler maintenance. Many models also support future energy transitions, such as hydrogen blends, offering long-term flexibility.
