The Baxi 624 System 2 is a compact, high-efficiency condensing system boiler designed to provide reliable central heating and hot water for medium-sized homes. With a 24kW output, it offers a practical solution for properties with moderate heating requirements and higher hot water demands, including homes with more than one bathroom. The wall-mounted design helps save space, while its compact dimensions allow it to fit inside a standard kitchen cupboard where the manufacturer's installation requirements are met.

Natural Gas and LPG Ready

The Baxi 624 System 2 provides added fuel flexibility, as it can operate using either natural gas or LPG without requiring a conversion kit. This makes it a versatile choice for suitable domestic heating installations.

As a condensing system boiler, the Baxi 624 System 2 is designed to provide efficient heating while delivering reliable performance. It includes an integrated pump and expansion vessel, helping simplify the installation process and reducing the need for additional external components.

Ideal for Higher Hot Water Demand

The Baxi 624 System 2 is well suited to homes with more than one bathroom or properties with greater hot water requirements. It can also be paired with a compatible hot water cylinder, providing flexibility when designing a complete domestic hot water system.

Smart Heating Control

The boiler is compatible with Baxi uSense and other suitable smart thermostats, giving homeowners greater flexibility when managing their heating. It is also OpenTherm certified, allowing it to work with compatible controls for more advanced heating management.

Quiet and Reliable Operation

The Baxi 624 System 2 is Quiet Mark accredited, reflecting its low-noise operation. It also includes an automatic shut-off safety feature designed to respond if the system detects certain operating abnormalities, helping provide additional reassurance during everyday use.

Built-In Frost Protection

A pre-heated siphonic condensate trap helps protect against freezing during cold winter conditions. This feature is designed to reduce the risk of frozen condensate affecting boiler operation when temperatures fall.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
