Accessory is not the most exciting topic but it can not be avoided, because accessories are still needed, should something be defective or you need it for a space heater with a thermostat to control.

Of course, you can also find other related products, such as Remote controls, condensate pumps or perhaps Installation tool (condensate lines, union nuts, etc.).
