When it comes to keeping engines in peak condition, not all coolant heaters are created equal. While the market is flooded with low-cost, mass-produced options, these often come at the expense of quality, reliability, and service life.

At Preheat Engineering, we take a different approach. Our FALCON Thermosiphon Coolant Heater is engineered for performance, longevity, and dependability, even in the most demanding environments.

Built to Perform. Built to Last.

The FALCON is more than just a heater, it’s a precision-built solution for professionals who can’t afford failure. Each unit is carefully manufactured using high-grade materials and rigorous quality control, ensuring it outlasts and outperforms the majority of generic heaters found on the market.

Key design advantages include:

•High-quality heating elements designed for long service life and consistent output

•Bi-metallic thermostat for precise temperature regulation and energy efficiency

•Corrosion-resistant components that withstand thermal cycling and harsh operating conditions

•Optimised coolant flow for effective thermosiphon circulation and even engine block heating

Designed for Ease of Use

While other products may involve complicated plumbing or unreliable mounting methods, the FALCON is designed for quick and simple vertical installation. Each model includes a 5/8” (16mm) hosetail and comes with a mounting kit for a secure, professional finish. Multiple voltages and CE-compliant models are available to suit a wide range of applications.
