How to look after your heat transfer plate
It’s important that your heat transfer plate remains in good condition. If it sustains damage it won’t transfer heat effectively to your machine and as a result, you may find that your machine doesn’t function correctly.
The plate is designed to be used on traditional domestic stoves. We recommend using a medium-sized gas ring of between 2-3 inches in diameter, or a medium-sized electric ring.
We recommend that you do not use any of the following stove types with your heat transfer plate, as they produce excess heat which can cause damage to the plate:
• Wok burner-style gas stoves
• Industrial-style stoves
• Camping gas stoves
Replacement plates are available if required:
- Heat transfer plate: this plate works on both gas and electric domestic stoves. It will not work on induction stoves. You can buy it here.
- Induction plate: this plate is designed to work on induction stoves. It will not work on gas or electric stoves. You can buy it here.
Note: The original silver heat exchanger plate, which worked on both gas and induction stoves, may delaminate into separate layers or bow out of shape if it’s left on the heat for too long, pre-heated or cooled with water. If this happens it won’t transfer heat to your machine. This plate is no longer available so if you require a replacement you have the choice of the new heat transfer plate or the induction plate.
