Answer:
First, ZG Group provides good quality industrial hot water boilers, not the hot water heater. You should know clearly what is suitable for you, boiler or water heater.
Hot water boiler: Hot water used for space heating may be heated by fossil fuels in a boiler, a closed vessel where water is heating. An industrial hot water boiler is at least 0.35MW or we say 0.5 ton, it can heat almost 3000 square meter. Natural gas, light oil, heavy oil, coal, biomass, wood pellet, rice husk and waste heat can be used in the hot water boilers.
Hot water heater: A traditional hot water heater is a storage tank with heating elements in it. The heat is generated by either burning gas or electricity. Typically the water is heated to around 125 degrees and kept at that temperature by a thermostat until it is needed. Then the water is drawn from the top of the tank, and sent through supply pipes to whatever fixture is calling for it, whether it’s a sink, a shower or your laundry machine. As the water is drawn off the top, fresh cold water is added to the bottom and gets heated along with the rest of the water in the tank.
