Unlike non-pressure water heaters, pressure water heaters require less maintenance. They are compatible with already installed water heating systems and have a electric heater to ensure a continuous supply of hot water on black-out days.
Despite the external similarities, simple pressure water heaters have fundamental differences from non-pressure ones. The water flows out with pressure. There is no water in the vacuum tubes. There is a copper rod in the pipes, which raises the temperature of the water in the water tank. The two systems are similar in that the vacuum tubes are integrated with the tank and placed on the roof. The systems can even provide domestic hot water for the whole year.
They are suitable for private houses, small and medium enterprises.
