35L BrewZilla Gen 4 - Heat Exchanger Dish (HED)

Heat Exchanger Dish for 35L BrewZilla Gen 4

This Heat Exchanger Dish (HED) upgrade for the 35 L BrewZilla Gen 4 is designed to improve heat transfer, speed up temperature changes and deliver a more efficient recirculation path during your mash. Pressed into a gentle concave shape, it matches the curvature of the BrewZilla’s boiler false bottom and includes a longer eye‑bolt assembly with a wing nut for secure, hassle‑free cleaning access.

By redirecting recirculating wort away from the central drain hole and toward the outer edge of the BrewZilla base, the HED forces the wort to pass over the heating elements for longer. This increases heat‑exchange efficiency and helps you reach mash steps and temperature targets faster — a real time‑saver on busy brew days.

For best results, pair this upgrade with the RAPT Bluetooth Thermometer to monitor and control mash temperatures from the core of your malt pipe.

How It Works

• Recirculated wort normally drops straight through the false bottom’s central drain hole.
• The HED blocks this direct path, pushing wort outward toward the BrewZilla’s heated base.
• This increases contact time with the heating elements, improving heat transfer and reducing waiting times between mash steps.
