Description

Complementary system of solar water heater and storage electric water heater

technical field

The utility model relates to a water heater, in particular to a complementary system of a household solar water heater and a water storage electric water heater, and belongs to the technical field of water heater equipment.

Background technique

At present, there are various types of household water heaters, such as solar water heaters, electric water heaters, and gas water heaters. There are three problems in the use of solar water heaters: 1. Unstable water pressure in households leads to unstable solar water temperature. 2. The temperature of solar water heaters in winter or rainy days is low, generally only ten degrees higher than the outdoor temperature, which cannot meet the needs of household hot water. 3. The amount of stored water is fixed, and the hot water storage cannot be expanded. Water storage electric water heaters can meet domestic water needs in various weathers, but consume more electric energy. Gas water heaters are a safety hazard.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described by example.

Referring to accompanying drawing 1, a kind of complementary system of solar water heater and water storage type electric water heater, comprises water storage type electric water heater 1, solar water heater 2, circulation pump and stop valve 3, water terminal A4, water terminal B5, electric water heater water injection pipe 6 , water injection port 7, solar water heater water injection pipe 8, solar water heater outlet pipe 9, electric water heater outlet pipe 10, valve one 11, valve two 12, valve three 13 and valve four 14, water storage electric water heater 1 is fixed indoors, and solar water heater The water heater 2 is fixed outdoors, and the water injection ports 7 of the water storage electric water heater 1 and the solar water heater 2 are respectively connected with the water injection pipe 6 of the electric water heater and the water injection pipe 8 of the solar water heater, and the water injection pipe 6 of the electric water heater and the water injection pipe 8 of the solar water heater are respectively provided with Valve four 14 and valve three 13, the electric water heater water injection pipe 6 and the solar water heater water injection pipe 8 communicate with the stop valve 3 through the circulating pump, and the water outlets of the water storage electric water heater 1 and the solar water heater 2 pass through the solar water heater outlet pipe 9 and the electric water heater respectively.
