Family Use Vacuum Tube Solar Water Heater - MXR-M470

vacuum tube solar water heater

Non Pressure Solar Water Heater Working Principle

The vacuum tube absorbs the sun’s rays and turns it into heat energy, heating the water in the tubes. As the temperature of the water rises it becomes less dense, so the hot water in the tubes float into the tank, and the cold water in the tank travels down into the tubes. This natural cycle keeps repeating and the water in the tank gets hot. This unit will work below freezing temperatures as the glass tubes are sealed and heat can only enter and not escape from them. Non pressure system drains by gravity, unit must be placed at high place above supply line.

Installation Notes:

1. Assembly of this unit typically takes less than one hour

2. Unit is gravity drain, must be placed at highest point of house

3. For maximum efficiency unit should be placed in an unobstructed view of sun light for eight hours a day

4. In freezing climates all exterior pipes should be well insulated

5.Reliable and efficient with twin-glass solar tubes

6. Easy plug-in installation
