You mentioned several types of electric heating: 1. If there is an electric heating port under your solar water tank, just install it directly. 2. If there is no electric heating port under the water tank, you can unplug it. one of the vacuum tubes and install an electric heater (similar to the one above, there are straight and curved ones) 3. Install it at the water inlet. This method can block the flow of water in the sewer pipe. It is generally not applicable. It is recommended to use both of the above! Generally, it is a 1500W installation method, which is sealed by a sealing ring. Simply remove the cap or vacuum tube under the water tank and install the electric heater~!
There are currently two types of solar brackets on the market: aluminum alloy brackets and carbon steel spray brackets can bemade into different shapes, while aluminum alloy profiles can only be used in rod form. structural supports. Relatively speaking, I always prefer aluminum alloy brackets, which are durable. There is also the stainless steel bracket, which is usually made of 430 stainless steel (commonly known as stainless steel) which is made of ferritic stainless steel. There will be rust spots on the surface in a humid environment, but it will not affect the structural strength. . The performance is better than carbon steel since the price is not favorable, not used much now.
