Is solar water heater heating water good?

In order not to worry about electricity bills every month, the choice of solar water heater is the best solution.

What is solar water heater?

Solar water heater, also called solar power, does not use electricity but takes energy from sunlight to heat the water, effectively heating the water to 96 - 98 degrees Celsius. Hot water will be saved. Store in a insulation bottle.

Solar water heaters use 1 of 2 types of pipes: oil pipes and vacuum tubes.

Water heating efficiency of solar water heaters.

The effect of good water heating depends on the number of pipes. The higher the vacuum tube or the oil tube, the better the heat absorption for the water effect.

Vacuum tubes can keep hot water heat up to 72 hours. The vacuum tube design with low transparency will transfer solar radiation into extremely good heat. 5-layer vacuum tube technology will absorb heat up to 99%.

Solar energy oil tube has an outstanding advantage over the oil pipe that is when the sun can be turned off, it can heat the water for another 1.5 - 2 hours thanks to the heat effect of the oil, ensuring the source of hot water is always abundant.

Solar energy tube has a heating time many times faster than the solar energy tube.

Solar energy oil tube has the ability to hold heat up to 96 hours.

Evaluation of advantages and disadvantages of solar water heaters

Advantages of solar energy:

Solar water heaters do not use electricity so they do not have to pay electricity bills monthly.

Flat solar panel is protected by a high-grade tempered glass for high durability, extremely good heating effect.

Airtight heat-absorbing tube minimizes fouling or moss in the tube.

The hot water heater is equipped with a insulation bottle to store hot water and heat so you can use bath, wash dishes, cook.

Solar energy has a longer service life than hot and cold water bottles. Easy installation, less damage.

Using solar energy is extremely safe, not afraid of electric shock, not afraid of fire and explosion.

Disadvantages of solar water heaters

1. The initial cost is quite high, the price is more expensive than the hot water heater.
2. Designing bulky machines takes up a lot of ceiling space.
3. The temperature of hot water is unstable because it depends on the sun's sunshine.
