Pre-heating Solar Water Heater (compact low pressure system) stainless steel Series
SF-1800-58-470-18-SSPH 150L with a Copper Coil inner Tank
150L 18 Vacuum Tubes Pre-Heating Solar Water Heater With Stainless Steel Tank
Description:
Pre-heating solar water heater (compact low pressure solar water heater) is comprised of three parts: water tank, vacuum tubes (collector), and support (bracket).
A copper coil inner tank is the main feature of pre-heating solar water heater (compact low pressure solar water heater). The copper coil directly connects with tap water, and the coil is under pressure, so that we also call pre-heating solar water heater as low pressure solar water heater.
Working Principle:
1) The working principle of Pre-heating solar water heater is more advanced than thermosyphon solar water heater (compact non-pressurized solar water heater). The copper coil directly connects with tap water. By natural circulation, the water in the tank becomes hot water, and the hot water transfers the heat to the water in the copper coil.
2) People can use the hot water directly from the copper coil, and the water is much better than that in the tank.
3) People can also use the hot water from the tank.
Features:
1. Lowest price. Most family can afford it.
2. Highest efficiency. The water fills the whole system, so that the heat loss is the least.
3. An auxiliary tank must be used.
4. The copper coil is under the pressure of tap water.
5. There is no need to wait and the hot water is available immediately.
6. SUS304-2B food grade stainless steel inner tank keeps the water quality, and it is innocuity.
7. SUS304-2B stainless steel outer tank
8. An electrical heater can be used as the auxiliary heating equipment.
Applications:
Pre-heating solar water heater (compact low pressure solar water heater) can be used for ordinary families, or appartments.
Bath room, hand/clothes wash, kitchen, and warm
