No. Each component of the SunMaxx solar collector is high-temperature rated and non-flammable, so even during periods of strong sunlight with the pumps off (stagnation), the system will not catch fire or give off sparks. The majority of components are stainless steel, aluminum, glass or glass wool. The manifold outlet should be fitted with a temperature relieve valve, which will prevent the manifold temperature from exceeding 99°C (212°F).
