Electric heater – Water heater that is operated with the help of an electric heater.

Solar water heater – Solar water heater (solar rays) and part of a solar system whose function is to store the hot water. An electric heater is installed in each boiler for heating the water when the sun’s heating is insufficient

Heat exchanger – Usually a heat exchanger is used for a water heater with solar energy (solar rays) similar to a solar water heater and part of a solar system whose job is to store the hot water.

In each heat exchanger boiler there is another unit (spiral tube) in which a liquid that heats from the solar energy flowing as heat transfer to the water inside the boiler.

The water inside the heat exchanger and the boiler water are two separate water systems.

And only the pipe comes in contact with the water in the boiler and heats them.

An electric heater is installed in each boiler for heating the water when the sun’s heating is insufficient.

Solar collector – part of a solar system whose function is to convert direct sunlight into heat energy. The collector consists of a system of pipes through which water passes. These tubes are fitted with a black absorption panel whose function is to absorb the sun’s radiation, as a result of which the absorption panel heats up. This heat is transferred to the pipe system and the pipe system to the water flowing inside.

Solar heating system – A system that utilizes the solar energy (solar energy) for water heating, and consists of a solar or heater based heat exchanger, a collector and a piping system that links the boiler to the collector.

Thermosiphonism – a thermodynamic physical phenomenon and means of fluid convection, heat transfer and the creation of a pump without spin.

In the thermosiphon system, the water heats at Colt flows to the top of the boiler,

Because hot water is lower density than cold water, the hot water floats above the cold water.

That is why the cold water is at the bottom of the boiler and the hot water at the top.

The cold water flows from the bottom of the boiler to the bottom of the colt. The water heats up in a floating colt and goes up the colt and flows back to the boiler. This creates a cyclic movement of water between the boiler and the colt.

Safety Valve – An external safety accessory mounted on the boiler to protect the boiler from cracking as a result of increased pressure. When the boiler pressure reaches 8 bar, the safety valve opens and unloads the boiler pressure (similar to a pressure cooker mechanism)

Repeat Valve – An external accessory that is mounted on the boiler with the purpose of protecting the boiler from the drainage of water contained within it as a result of a water break.

Silhouette Valve – An external accessory mounted on a solar system boiler when the boiler is lower than the top of the collector and prevents hot water from boiling to the boiler as a result of a physical phenomenon called reverse thermosiphonics, in which the hot water flows to the collector and cools, causing the boiler to cool.

Heat booster – A unit made up within the boiler that delivers a limited amount of water around the heater and its function to cause accelerated heating of that limited amount of water. This unit has a long, narrow tube that carries the amount of water that has warmed to the top of the tank. This unit only consists of solar water heaters installed in a standing position.

Plan – A set of components for the boiler that includes: a metal plate with a heating element and a thermostat + heat booster unit + a rubber gasket for the plate.

Heating element – unit in the boiler’s electrical system that converts the electrical energy into heat energy, and its function to heat the water in the tank (similar to an electric water kettle)

Thermostat – A unit in the boiler’s electrical system with wiring to the heater and its function to control the water temperature. When the water temperature reaches 60 ° C, this unit causes the heater to be disconnected from electrical power and thus stops the heating operation.

Differential thermostat – a temperature control unit whose function is to control the measured temperature at the inlet and outlet of the collector. As long as there is a (differential) difference in temperature

From 7 ° C, the thermostat will command the spin pump to operate.

Swivel Pump – The swivel unit functions to create a forced swirl of water between the collector and boiler or heat exchanger.

Boiler – A nickname for solar water heater or boiler Boiler is a foreign word that has come to our fore when they say to turn on the boiler intend to turn on the electric component in the boiler in order for the water in the boiler to heat up.

Kilo-calories – calories = unit of heat and energy.

Kilos = 1,000 thousand units

Pounds of calories = 1,000 calories.

Watt – Measuring unit for electrical power of the heater

Supplier – The amount of work invested or received per unit of time.

Temperature mixer – An external safety accessory consisting of a solar water heater designed to control the water temperature being flowed from the water heater to the home, since the solar water heater cannot be stopped and the hot water can reach high temperatures, control and protection from burns are needed.

This accessory usually aims at a temperature of 50 ° C to protect against burns.

Electric boilers when the water temperature is controlled by a thermostat do not need this accessory.

Thermosiphon system – Solar water heating system which includes: boiler, collector and connecting pipe and which water in this system is naturally spun according to the physical law of thermosiphonics.

This spinning method can only take place when the boiler is above the receptacle.

An open system – a solar water heating system in which the water inside it swirls between the boiler and the collector. And the swirling water is the consumed water.

Closed system – a solar water heating system that has two separate water systems. One system in which the water is in the tank is the consumed water. A second system is the water in the collector and in the heat exchanger coil that in this water boiler swirls between the exchanger and the collector and heats the water in the boiler but is not consumed.

Forced system – a solar water heating system that includes the base: boiler, collector, piping linkage, and differential thermostat, which water in this system swirls with a pump. These systems are used when the boiler cannot be placed above the receptacle.

Low Silhouette System – Solar water heating system characterized by a lower altitude than a normal system
