Vacuum hot water boiler is absolutely safe and is praised as the boiler without explosion forever because it operates in the negative pressure. During the operation process of the boiler, the hot media (water in boiler) doesn’t make any change; it only stays in the vacuum chamber and transfer heat between heat-exchanging tube and heat exchanger.

Vacuum hot water boiler is an ideal solution for heating supply, gas and oil are available to be used in the heating boiler. There is completely deoxy purified water in the furnace, so there is no corrosion and incrustation.

That vacuum breaker needs to be installed about 6 inches +/- above the top of the tank. It needs to be installed AFTER the cold water shutoff into the heater.

Author: AC Service Tech LLC As hot water leaves the tank, it automatically fills it with fresh water that is heated. Because water heaters only deal with water and not your home’s heating system, replacement costs are less. The average hot water heater installation cost is $881. On the other hand, a boiler provides hot water and heat throughout the home.

Essentially, a water heater is a storage tank with heated tubes that keep the water at a certain temperature. When hot water is needed, the unit siphons hot water from the top of the heater. It then replenishes its supply by heating cold water and moving the freshly heated water to the top.

Vacuum hot water boiler adopts the principle of water-fire tube boiler, SU304S stainless steel heat exchanger, high heat transfer efficiency of flue gas, compact structure, high efficiency and energy saving, ultra low NOx emission and small volume. The vacuum boiler operates under negative pressure and has multiple protection functions.
