Outer wall solar central water heater

Abstract

The invention relates to a central water heater used on an outer wall body, which comprises a window (2) arranged on the opening of the wall body; an airtight heat storage room (6) made of light transmission glass plates (7) is arranged a wall (1) around the window; a solar heat exchanger (8) is arranged on the wall (1) inside the heat storage room (6); a hot water inlet (10) and a tender fillinghole (13) of a hot water container (4) arranged indoors are respectively connected with a heat exchange tube water inlet (3) and a heat exchange tube water outlet (9) of at least one solar heat exchanger (8); a hot water outlet (15) and the hot water inlet (17) of the hot water container (4) are respectively connected with a shower head and a tap water network through a pipeline. Test improves that the invention has simple construction, easy and convenient installation without damaging the water barrier of the building, sufficient hot supplying in summer, and well running in winter. The manufacturing cost and the running cost are low, the application range is wide, the hot water can be supplied centrally, and the invention can also be used in families.

Description

Technical field [0001] The invention relates to a solar water heater, in particular a central water heater with an outer wall body, which is suitable for installation in bath buildings, residential buildings and office buildings. Background technique [0002] In the past, the hot water in traditional baths usually used a boiler to directly produce hot water or produce steam to heat cold water to provide hot water to the bathroom. With the development of industry and the improvement of people's living standards, direct-fired gas water heaters and electric water heaters have entered the homes of ordinary people, providing convenience for people to bathe and use hot water at home. However, despite this, many years of practice have also revealed unsatisfactory disadvantages such as high cost of use (consumption of gas and electricity) and certain hidden safety hazards (such as carbon monoxide poisoning, and danger to personal safety once leakage). Based on the above reasons, in rece...

Problems solved by technology

However, because the outdoor water heater is usually installed on the sunny side of the roof and needs to penetrate the waterproof layer of the roof, the construction requirements are strict, and a slight negligence can easily cause water leakage

In addition, the operation effect is not good in the cold winter in the north, and antifreeze measures need to be taken even if it is disabled. Although the situation of freezing and bursting glass tubes also occurs from time to time, the promotion and application of the glass tube in the cold winter in the north is limited to a certain extent, and further improvement is needed.
