The quality of the Samp solar water heater is good. It can reach 40 degrees in winter, so you can rest assured. It doesn't matter if it's four or seven tubes or five or eight tubes, just choose the number of liters you need. Generally speaking, it is calculated at forty liters per person. The cheapest one should be purchased, because the solar water heater is proportioned according to the surface area of the collector and the water tank during its manufacture, that is, whatever the tube, the total surface area is the same. . For the same size water tank, the number of 58-inch pipes is small, while the number of 47-inch pipes is large. This should be clear.
The Samp balcony wall-mounted solar water heater is very good. The water tank is cylindrical and adapts to the needs of indoor installation locations of different types of apartments. The collector has a simple shape,smooth lines and elegant appearance. It is the first choice for high-end modern residences such as villas and high-rise residences. It shows environmental protection, fashionable style, and can better reflect the owner's noble taste. .
I hope my answer can help you.
