ThermaHive V2

The Heater Insert is the working heart of the ThermaHive system. It snaps into any Bottom Treatment Frame via a magnetic locking connection, connects to the controller, and brings your hive up to treatment temperature with a self-regulating 500W PTC ceramic heating element. When the treatment is done, pull it out in seconds and move it to the next hive.

How It Works

Plug In. Treat. Move On.

The Heater Insert handles the hard part — converting electrical power into precise, controlled heat that fills your hive evenly during treatment. One insert can move between any number of hives equipped with a Bottom Treatment Frame.

🔥
PTC Ceramic Heating — Self-Regulating by Design
The 500W PTC (Positive Temperature Coefficient) ceramic heating element is inherently self-regulating — its electrical resistance increases as it heats up, which naturally limits power draw and prevents thermal runaway without any additional circuitry. The ThermaHive Controller still governs the treatment profile, but the PTC element adds a built-in layer of safety at the heat source itself.
🔒
Snaps In. Pulls Out. No Tools.
The Heater Insert connects to the Bottom Treatment Frame via a magnetic locking system — no screws, no clamps, no straps. It seats securely during treatment and releases cleanly when you’re done. Moving it to a different hive takes seconds. If you have multiple hives equipped with Bottom Treatment Frames, a single Heater Insert can rotate through all of them.
⊕
Add a Second Heater to Treat Simultaneously
One Heater Insert with one controller treats one hive at a time. Add a second Heater Insert — along with a second controller (Top Box) — and you can run two full treatments simultaneously on separate hives. This is the most efficient configuration for larger apiaries where mite pressure means you need multiple hives treated at once, not one after another.
🌡️
Precision-Controlled by the ThermaHive Controller
The Heater Insert doesn’t operate on its own — it works in tandem with the ThermaHive Controller (Top Box), which monitors hive temperature via the wireless sensor and switches heat output through a KY019 relay, backed by a KSD301 thermal switch and an SF96E thermal fuse. The controller maintains your target treatment temperature throughout the session and logs every data point to the SD card. The Heater Insert is the muscle; the controller is the brain.
