The Baxi 418 is a highly efficient 18kW heat-only boiler engineered to deliver reliable thermal performance in traditional domestic heating systems. With an exceptionally low lift weight of just 17.5kg, this unit significantly reduces installation fatigue and requires minimal effort during wall mounting. The compact footprint measures 625mm high, 370mm wide and 270mm deep, ensuring seamless integration into standard kitchen cupboards. It provides an excellent retrofit solution for older properties as it functions entirely without a pump overrun or a permanent live connection.

Designed to simplify complex boiler replacements, the system offers versatile exhaust routing through either a central top flue or a discreet in-case rear flue configuration.
