joints and mating areas of parts are treated with silicone sealant at all stages. To protect the structure from precipitation, the wood is coated with a special composition and painted with enamel.

Features of installation and operation of liquid heating collectors
To place the solar collector, choose a spacious place that is not shaded during the entire daylight hours. The mounting bracket or subframe is made of wooden slats or metal so that the tilt of the water heater is adjusted within 45 to 60 degrees from the vertical axis.

To install a solar water heater, a support frame is assembled.

Connection to an indirect heating boiler or heat japan mobile database is performed using threaded fittings and copper, metal-plastic or multilayer polypropylene pipes. They are covered with a layer of thermal insulation.

The storage tank is placed as close to the unit as possible to reduce heat loss. Depending on the conditions, natural or forced circulation of the coolant is organized. In the latter case, a controller with a temperature sensor embedded in the outlet pipe is used. Pumping of the working fluid along the circuit will be switched on when its temperature reaches the programmed value.

A seasonally operating system is filled with water, while year-round use of a solar water heater requires the use of an antifreeze. The ideal option is a special antifreeze for solar systems, but for economy, liquids intended for car radiators or household heating systems are also used.
