Which is more affordable, solar vs. air water heater?

Generally speaking, solar energy is cheaper in terms of price, solar water heaters cost hundreds of yuan or more than 1,000 yuan, and air source water heaters are not so cheap. The operating cost in daily use depends on the region. Different regions determine which is cheaper to run.

Mainly look at the annual sunshine time, when one-third of the annual sunshine time has no sunlight, the operating cost of the two of them is comparable. More than two-thirds of the sunshine hours are low, and the operating cost of air source heat pumps is lower. Of course, this only refers to most places, not to alpine regions, such as the Northeast.

This comparison is compared with the cost of electricity, because when the air source heat pump is between minus 5 degrees and minus 30 degrees, the electricity consumption of each ton of water produced is equivalent to one-third to one-sixth of the direct electricity consumption, and solar energy needs to rely on electricity to boil water when there is no solar energy. So when there is sunshine, the cost of solar energy savings, when there is no sunshine, because of the large power consumption will increase, the overall year, whose operating costs are low depends on the sunshine time.

There is no other cost for ordinary solar energy after a single investment. Air energy water heaters must consume a certain amount of electricity per day before they can be used. It is recommended that you buy a regular solar water heater with electric heating.

If electricity is heated a hundred days of the year, then their running costs are about the same. But the amount of water that can be used in the air is not as limited by the tank as solar energy, and it's not as strongly affected by the weather as solar energy is. If the landlord uses a lot of water, you can consider using air energy.

It depends on the use of solar energy in the ** area, solar energy is affected by rainy weather, more than 100 days a year is a rainy day, in addition to the winter sunlight is often insufficient, air energy also depends on the region, the ambient temperature is lower than minus 25 degrees, it is not energy-saving. If you are in an area south of the Yellow River, it is recommended that you use an air energy water heater.

When there is no solar energy, of course, you have to use other methods to achieve the heating effect.

But "Cicero Solar" as long as there is light there is hot water, but it has not been able to reach a very high temperature (at this time only a little electricity is needed), no matter what, "Cicero Solar Water Heater" is definitely the most energy-saving "hot water bather", after all, it is a "photoelectric cooperation" hot water instrument, "light" has helped you save a lot of electricity.

Solar water heater is good.

The working principle of air energy water heater is a heat pump, through which the heat energy in the air can be transferred to the water to heat up the water. Its heating coefficient directly depends on the air temperature (air temperature), and the intensity of sunlight is not light. The heating coefficient can reach 7-8 in the hot summer and only 2-3 or even lower in the winter.

Whereas, heat pumps need to consume electricity to work.

Solar water heaters can convert light energy into heat energy, so as long as there is sunlight, hot water can be produced, if the heat collection area is large enough, the water capacity is large enough to use up hot water on the day, and the next day even if there is no sun, there can be hot water. On rainy days, you can also use auxiliary electric heating to save the emergency. Air energy water heaters need to occupy a certain amount of housing space, while solar energy does not take up indoor space.

How to choose a water heater:

1. Look at the inner tank, the inner tank of the electric water heater is divided into stainless steel inner tank, enamel inner tank, and galvanized inner tank, among which the stainless steel inner tank has the best quality and long life, which is slightly higher.

2. The galvanized liner has the shortest life and low cost.

3. Pay attention to safety performance, electric water heater should have anti-dry boiling, anti-over-temperature, anti-overpressure device, leakage protection and automatic disconnection without water, as well as additional power-off indication functions.

4. It is safer to choose products with large thickness of moisturizing layer and high density of insulation materials.

5. The key to the impact of thermal insulation effect on the power consumption of water heater is the thermal insulation effect, and it is more energy-efficient to choose products with large thickness of moisturizing layer and high density of thermal insulation materials.

6. Pay attention to the heating pipe of the electric water heater, the quality of the heating pipe, and the electrical performance of the electric heating pipe directly affect the use of the electric water heater.
