Holroyd Components can offer a wide range of bi-metal thermostats and thermal devices for sale. They include our 0.5 inch Disc, U12 Uchiya & Pepi Ja, with both auto and manual reset solutions available. The temperature options we stock range from +5°C to +220°C - these can either be directly wired into the circuit of the heater, or wired separately.
