Water heater removal steps:

Tools/materials: water heater, wrench.

1, first remove the hose, the water heater inside the water drain.

2, and then two people work together to lift the water heater upward some, and then move outward on it.

3, electric water heater is usually hung on the wall, if it is fixed with screws, first loosen the screws.

Water heater working principle:

A complete household multifunctional water heater contains 2 main parts:

1, its internal structure mainly consists of four core components: compressor, condenser, expansion valve, evaporator.

2, its workflow is this: the compressor will return to the low-pressure refrigerant compression, into a high-temperature and high-pressure gas flow through the pipeline, high-temperature and high-pressure gaseous refrigerant flow through the winding in the water tank outside the copper pipe, the heat is conducted by the copper pipe to the water tank, heat exchange, cooled down the gaseous refrigerant in the pressure continues to turn into a liquid state, through the expansion valve and then into the evaporator, due to the pressure of the evaporator The pressure of the evaporator is suddenly lowered.

So the liquid refrigerant here quickly evaporates into gas, and absorbs a lot of heat. At the same time, under the action of the fan, a large amount of air flows over the outer surface of the evaporator, the energy in the air is absorbed by the evaporator, and the air temperature is rapidly reduced, becoming cold air discharged into the kitchen. Subsequently absorbed a certain amount of energy refrigerant back to the compressor, into the next cycle.

3, by the above working principle can be seen, the working principle of domestic multi-functional water heater and air conditioning principle has some similarity to the application of the principle of inverse Carnot, through the absorption of a large number of low-temperature heat energy in the air, through the compressor compression into high-temperature heat energy, transferred to the water tank, the water heated up.

The whole process is a process of energy transfer (from the air with the transfer to the water), not the process of energy conversion, there is no electric heating element to heat the hot water, or burning combustible gases to heat the hot water.
