Will the Solar Thermal Collector be a fire hazard during hot/dry weather?

Not at all. The hot solar thermal fluid is contained within the copper lines. Each component of our Solar Collectors are high-temperature rated and non-flammable, so even during periods of strong sunlight with the pumps off (stagnation) such as in a drainback system, the system will be no fire threat. The Evac Tubes are cold to the touch even while they are producing over 150 F water to your house heating and/or DHW tank. The majority of components are stainless steel, aluminum glass or glass wool. The manifold outlet will be fitted with a pressure/temperature relieve valve, which will prevent the fluid temperature from exceeding it limits.
