Add a 3-way connection under the solar water supply valve, one end is connected to the water, one end is connected to the solar water supply valve, one end is connected to the gas water heater and a valve is added. When using solar energy, turn off the added one. When connecting the valve and water outlet pipe of the gas heater to the hot water pipe, a 3-way connection is also required, which is very convenient.
As shown in the figure below, the outlet pipes of the two water heaters are connected to the pipe leading to the faucet with a tee. A valve is installed in front of the tee and on the side leading to the tee. the water heater.
When using a solar water heater, simply close the valve leading to the electric water heater; otherwise, close the valve leading to the solar water heater; The water supply pipe (cold water) does not need to install a valve here.
Gas water heater, also known as gas water heater, uses gas as fuel and transfers heat to flow through heat exchanger via heater by combustion A. gas appliance that uses cold water in an appliance to prepare hot water.
The solar water heater is a device that uses sunlight to heat water.
Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters. Evacuated tube solar water heaters account for 95% of the domestic market share.
1. Install a ball valve on the solar hot water outlet pipe. When using solar energy, the valve opens and the electric water heater valves are closed at the same time. time, so that it can be used solar water. When using an electric water heater, close the solar valve andopen the electric water heater valve.
2. The solar water heater tank is equipped with auxiliary electric heating. If the water temperature is not sufficient, you can directly use auxiliary electricity to heat the water temperature, which is much faster than the heating time. of an electric water storage water heater. When the weather is bad, do not fill the solar water tank, just fill it halfway. This way the heating time will be faster, making it easier to use hot water.
If you want to connect a solar water heater and an electric storage water heater, you need to purchase two tees and a water valve to connect the connecting water pipe of the solar water heater to the water pipe. of the electric water heater.
3. Electric water heater refers to a water heater that uses electricity as energy for heating.e. It is one of the three main water heaters, alongside gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to heating power: water storage type (also called volumetric type or heat storage type), instant heating type and instant heating type.
4. Solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters accounting for 95% of the domestic market share. Household vacuum tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collector tubes. Pouring cold water to produce microcirculation in the waterto reach the required hot water level.
