Solar water heaters, or solar thermal water heaters, utilize natural sunlight to heat water, catering to human needs.
In addition, solar water heaters are eco-friendly and promote optimal energy savings. While buying a solar water heater is easy, achieving convenient installation and optimal performance requires careful attention to these 5 factors:
1. The installation location of a solar water heater must receive ample sunlight.
Since solar water heaters rely on sunlight to heat water, they should be installed in areas with abundant sunlight. This type of solar energy system may not be suitable for households in apartment buildings due to difficulties in capturing sufficient sunlight to heat water.
Typically, solar water heaters are installed on the roof to maximize direct sunlight absorption. The ideal time for optimal sunlight absorption is from 11 a.m. to 3 p.m.
2. Prepare the water tank
Before installing a solar water heater, your household needs to have a water tank. Specifically, the recommended capacities are as follows:
- 120-140 liters suitable for 2-4 people.
- 160-200 liters suitable for 5-8 people.
- 200-300 liters suitable for households with over 8 people.
- Over 300 liters suitable for places with a higher number of occupants such as guesthouses, hotels, hospitals, etc.
3. Water pipe system
Prior to installing a vital appliance for your household, you need to inspect and carefully consider how to install the water pipes in the most scientific and convenient manner to avoid encountering difficulties later on. The water pipe system plays a crucial role, and if installed improperly or hastily, it can be very troublesome to repair.
1. Installing solar water heaters: What you need to know
Typically, the cost of installing a solar water heater can be relatively high due to additional purchases required such as fixed stands, water pipes, etc.
2.5 Considering whether to buy an oil-tube or regular solar energy system
Oil-tube solar energy systems operate on the principle of thermal convection and the greenhouse effect. Sunlight heats the oil inside the tubes and then heats the thermal conductive bars on the top inserted into the tank. Consequently, the water in the tank gets heated.
Generally, oil-tube solar water heaters have a clear advantage over regular tubes. Oil tubes do not accumulate sediment and can maintain heat even when the sun is not shining, ensuring prolonged hot water supply. Therefore, despite the higher price tag of oil-tube solar water heaters, which is typically 1-2 million dong more than regular tube ones, investing a little extra for a superior experience is worthwhile considering the notable advantages they offer.
