What is a Solar water heater, and How does work a Solar water heater?

This is a solar-powered appliance, and solar water heaters are typically mounted on roofs. It comprises solar radiation collectors that face the sun to capture solar radiation. Cold water first enters the vacuum collector tube at the initial level. The solar energy the collector absorbed here causes it to warm up. Water starts to rise or warm as the temperature rises. It then moves into an insulated tank where hot water can be kept for extended periods. The insulation prevents heat loss, keeping the water hot even when used hours later. And that is how a solar water geyser based on collectors works. Long-term water storage, a thermostat, a timer, notification, an alarm system, and many other features make this kit the ideal solar geyser.

Types of solar geyser

Here, we will disclose the Type of solar geysers. Which is best and which is affordable? In general, there are two types of solar water heaters ETC and FPC water heaters, and we will discuss both here.

  • FPC (Flat plate collector)

Flat Plate Collector is another name for the solar geyser. The FPC is more well-liked than the ETC solar geyser. It has a glass-covered rectangular box with a rectangular shape. Its metallic construction makes it enduring. The placement of the connected copper pipes, which allow water to flow through them, is particularly attractive. It must be anticorrosive because it is a rooftop appliance. As a result, it has an enamel coating, and various companies offer various coatings and anti-rust technology.

  •  ETC (Evacuated Tube Collectors)

Evacuated Tube Collectors is the full name for ETC. Glass tubes are used to capture sunlight. Through a multitude of annealed glass tubes, each of which has its own heat-absorbing plate within, evacuated tube collectors collect heat. There are many distinct designs, yet they all operate on the same fundamental idea. Essentially, each tube functions as a miniature greenhouse that collects sunlight, which is then utilized to heat the water or a unique fluid that distributes heat to the water.

Buying Guide

How to find the best solar water heater | Buying guide of the solar water heater or solar geyser.

So many brands, features, quality, and different norms are available in the water heaters. You should keep in mind these factors before buying a solar heater.

  • Solar Type: there are generally two types of solar types. You should buy one that suits your requirements. Both have their own advantage and pros along with their cons. FPC is better as they are cost-effective, easier to install, has low maintenance costs, and can extract heat energy from humid areas. On the other hand, ETC is more efficient in transferring heat than FPC- up to 163%.
  • Dual function: Normal solar water heaters only function when it’s warm outdoors. If you want consistent performance out of your heater, try settling for a dual-purpose gadget. However, even when it is not as sunny outside, the dual function ensures the device’s great performance.
  • The Size: This is a one-time purchase, so if you’re searching for a solar water heater, choose the standard size instead of always choosing larger models. Although expensive, their effectiveness and performance make up for the high cost.
  • Safety Majors: This kind of equipment must have significant safety features. Safety in the large appliance’s construction materials, connected inlets, tank, and other components
  • Brand: We advise you to pick well-known brands over the many affordable solar heating options from lesser-known manufacturers. This attests to the product’s dependability and guarantees that it will endure longer than equivalent models with a lower price tag.
  • Warranty: You should not buy a water heater that isn’t backed by a warranty. The best solar water heaters should have a 10- to 15-year warranty.
  • Cost: Solar water heaters are generally more expensive than electric water heaters. These water heaters are offered at various price points. However, they come at a significant initial cost, even though they might help you save money on electricity. Therefore, if you plan to use a solar water heater for a long period and live somewhere permanently, go for it.
  • Purpose or Use: Solar water heaters are ideal for large offices or any other department that need water heaters for your office building because they are large in size, require no maintenance, use no electricity and save money from your electricity bill. They’ll help you save a lot of money on electricity, and you’ll quickly recoup your investment. However, be cautious about purchasing a highly efficient solar water heater as otherwise, especially in the winter, you risk receiving cold water after a short period. 

Also, if you reside in a tropical area where water heaters are rarely used, avoid purchasing a solar water heater. When compared to electric water heaters, they are relatively expensive.

  • Climate: When buying a solar water heater, this is absolutely essential. In an emergency (rainy season), you may wish to think about a solar water heater that also uses electricity; unfortunately, this feature is only available on a limited number of solar water heaters. Some brands may only withstand the cold for a few days before they start producing typical cold water. So you might want to think about a multi-featured solar water heater if you live somewhere where it gets chilly for a long time.
  • Geographical Location: Your Solar Water Heater’s ability to heat water directly depends on how much sunlight it receives. It will work better if you reside in a place nearer to the equator. However, its heating capacity will drastically diminish as you get further away from it.
  • Tank Quality: The tank ought to be rust-free and capable of retaining heat for an extended period. It will last without leaking if it has a high-quality structure and finishes.
  • Certification: Last but not the least, although it’s not absolutely necessary, most nations have certification requirements for certain products. Therefore, confirm that your product has been accredited by regional or national standards.
  • Temperature Regulation– To keep the temperature at its ideal level, getting a water heater with a thermostat is essential.
  • Type of Collectors: FPC and ETC are the two main categories of collectors. Metal-based FPCs heat up quickly and cool down almost as quickly. Although durable, they are only appropriate for tropical areas. ETCs are fragile and constructed of glass, yet they are better at retaining heat. They are appropriate for both tropical and temperate climates.

How Does A Gas Geyser Work?

A flame starts when you turn on the tap connected to the gas geyser. Typically, a click sound is present to indicate the same. The heat exchanger contains water pipes that are protected by metal fins. These fins heat up when the flame is lit, which heats the pipes.

Additionally, the water that passes through these pipes heats up. The technique is quite quick; as soon as you turn on the faucet and light the flame, hot water begins to flow.
