Product Information

Baxi Assure System 2 Boiler Only

The Baxi Assure System 2 is a compact system boiler designed to provide efficient heating for central heating and hot water systems. Available in 18kW and 24kW power ratings, it offers a choice of outputs to suit different property and heating requirements. With its lightweight and compact design, the boiler is well suited to installations where space is limited. Its cupboard-fit design helps keep the boiler discreet, while a range of practical installation and maintenance features makes it a convenient choice for heating professionals.

Available Power Ratings

The Baxi Assure System 2 is available in the following power options:
  • 18kW
  • 24kW
The 18kW option is suited to properties with more modest heating requirements, while the 24kW model provides a higher output for homes requiring additional heating capacity. The appropriate output should always be selected based on the requirements of the property and heating system.

Compact and Lightweight Design

Designed with installation flexibility in mind, the Baxi Assure System 2 has a compact and lightweight construction. Its cupboard-fit design can be particularly useful where installation space is restricted, helping the boiler sit neatly within the home. A supplied hanging bracket also helps provide a practical mounting solution during installation.

Durable Heat Exchanger and Hydraulic Block

The boiler features a stainless steel heat exchanger, providing a durable component for efficient heat transfer. A robust brass hydraulic block further supports the boiler's long-term reliability and everyday performance.

Protection Against Cold Weather

The Baxi Assure System 2 includes a pre-heated and siphonic condensate trap designed to reduce the risk of condensate freezing during cold winter conditions. This feature can provide additional reassurance where low temperatures could otherwise affect condensate drainage.

Easy Installation and Maintenance

Thoughtful design features help make installation and servicing more straightforward. The combined pressure relief valve (PRV) with a separate drain facilitates easier maintenance, while removable, easy-access wiring blocks provide convenient access when electrical connections need to be installed or serviced.

OpenTherm Certified

The Baxi Assure System 2 is certified for OpenTherm, allowing it to work with suitable OpenTherm-compatible heating controls. This can provide more responsive control over the heating system and help optimise heating performance.

2-Year Parts and Labour Warranty

The boiler is supplied with a 2-year parts and labour warranty, giving homeowners added peace of mind. Warranty terms, conditions and any registration requirements should be checked with the manufacturer.

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. You'll receive tracking details once your order has been dispatched, and if we need to confirm any delivery details, one of our team will contact you directly to keep everything running smoothly.

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.
