Description

A solar heating device

technical field

The utility model belongs to the field of heating equipment, in particular to a solar heating device.

Background technique

How to heat in winter has always been one of the problems that affect the lives of most people. For people living in northern cities, central heating is undoubtedly the lowest cost and best heating method, but for rural areas without heating and people without heating In southern cities, heating in winter is a big problem.

Existing heating methods include:

1. Electric heating, whether using electric heaters, air conditioners, small suns, etc., are all heated by electricity. This heating method not only has high emergency costs, but also causes indoor air to dry out, and the temperature drops immediately after turning off the appliances.

2. Coal stoves are used for heating, such as braziers and stoves. Compared with electrical heating, the cost of this heating method is much lower.
