Frequently asked questions
Are Biasi and Cointra the same?
Biasi is linked to the Cointra group and shares some components and platforms. However, they are distinct brands with their own models. Many minor spare parts (thermocouples, electrodes) are compatible between both brands.
What should I do if my Biasi water heater does not ignite?
The most common issue with Biasi water heaters with a pilot light is the defective thermocoupleThe pilot light ignites but goes out when the button is released. If the ignition is automatic, it could be the piezo electrode or the gas valve. The thermocouple is an inexpensive part and the most commonly replaced in this type of equipment.
How often should a Biasi unit be serviced?
Annual inspection for sealed water heaters. Atmospheric ones require inspection of the flue duct every year due to safety regulations.
