Types of Instant Solar Shower Water Heater

An instant solar shower water heater uses sunlight to heat water for showers. This heater is popular in camping sites, beach resorts, and homes. There are different types of solar shower water heaters, such as portable camp showers, garden showers, and deck showers.

• Portable camp showers

  An ideal choice for outdoor enthusiasts who need a warm shower after a long day of hiking. A portable solar shower is easy to carry around because of its lightweight and compact nature. It uses a water reservoir bag to hold and heat the water using sunlight. Portable solar showers are typically 2 to 5-gallon capacity bags. They also come with a showerhead attached to a hose for easy bathing. Some shower bags have dark-colored exteriors to absorb and retain heat from the sun. A portable shower usually takes about 5 to 6 hours for the water to heat up before using it for a shower.

• Garden showers

  Garden solar showers are usually fixed. They consist of a shower pole and a water reservoir. The design of these showers makes them a great addition to any garden. Plus, they provide an eco-friendly way to cool off on a hot day. A solar garden shower has a tube with a reflective surface inside to absorb the sun's heat. This causes the water inside to heat up. Garden showers come in various styles, like the tower style or the outer tube with spirals. Also, they have different capacities, which could be 30, 40,or 50 liters. A solar garden shower heats water in about 3 hours if the outside temperature is about 20°c (68ºF).

• Deck showers

  Deck showers are popular in beach houses and resorts. They are located near swimming pools or in backyards. A deck shower provides a quick rinse after swimming or to cool off. These solar showers are made with durable materials, such as stainless steel or powder-coated aluminum, to withstand harsh environments. Also, they have a stylish and shine appearance. A deck shower consists of multiple showerheads for a refreshing experience. It usually features a holding tank with a capacity of about 70 liters or more. The water in the holding tank can be heated in about 1 to 2 hours if the sun's heat is intense.

Functions and Features

Instant solar shower water heaters are ingenious devices that use the sun's energy to heat water. They are designed for outdoor showers, camping, and off-grid living. These heaters use solar panels or collectors to absorb sunlight and warm up the water inside them. Here are some of the features and functions that come with solar shower water heaters:

• Energy efficiency

  Outdoor solar water heaters are the most energy-efficient water heating systems available. They do not use any electrical power or fuel to operate. All outdoor solar water heaters rely entirely on the sun's energy to heat water, saving the environment and reducing energy costs.

• Water supply systems

  There are two main types of outdoor portable solar showers - pressurized water supply systems and non-pressurized water supply systems. Non-pressurized systems rely on gravity to make water flow from the storage tank, while pressurized systems have a built-in pump that supplies water under pressure. Some portable solar showers include a pump to make the water spray from the shower head at a higher pressure.

• Showerhead and controls

  The showerhead provides a means to enjoy a refreshing outdoor shower after a long day of activities. Most solar showers have a simple on/off control that allows users to stop or start water flow through the showerhead.

• Storage capacity

  Solar water heaters come in different tank sizes to accommodate varying capacities. These capacities can hold between 8 and 10 gallons of water. The tanks store heated water from the daytime for use during showers or other activities. Tanks with larger storage capacities provide more hot water, while smaller tanks are more compact and easy to carry.

• Durable construction

  Solar shower water heaters have durable and weather-resistant constructions. Most are made from rust-resistant materials such as stainless steel or strong plastics. This durable construction can withstand the harsh conditions that come with frequent outdoor use.

• Integrated handles

  These portable shower water heaters come with built-in handles for easier transportation and handling. The handles make it easier to move the shower around or hang the shower from a tree or pole when it's in use.

How to Choose Instant Solar Shower Water Heaters

A consumer or retailer market for solar water heating systems has developed as a result of rising energy costs and environmental concerns. When choosing a solar-powered water heater, there are other factors to consider other than cost. These include the kind of collector, size and capacity, durability and maintenance, installation, and regulatory compliance.

When comparing various instantaneous solar shower water heaters, one must first grasp the distinct kinds of collectors stated below:

• Evacuated tube collectors: Modern evacuated tube collector designs are well known for their high performance. They are perfect for conditions with extremely low temperatures or where there is a lot of frost. The heated water in these tubes rises to the top as the temperature inside the evacuated tube rises. A phase change occurs when a small amount of water vapor inside the tube condenses on the inner surface of the tube, forming a ring. The ring's movement creates a vortex that propels the water upward, generating steam. This steam provides excellent insulation for the tube by creating an internal vacuum. Because of this vacuum, the concentrated sunlight cannot escape, and water in the tubes heats up quickly.
• Flat-plate collectors: A glazed flat plate collector, as the name implies, is a set of flat panels with a glass cover and black-coated metal pipes mounted on a roof. How well these collectors work depends on the weather, how much sunshine there is, and the temperature of the water that is being heated. They are frequently utilized to heat swimming pools.
• Integrated collector-storage systems are made to work best in temperate and tropical climates. They can sometimes be utilized in more excellent regions where heating water for outside showers is only sometimes necessary. Whenever the outside air temperature is above freezing, these systems can heat water based on how much direct sunshine hits them. ICS systems consist of two components: a water storage tank and a series of black-painted tubes.

Instant water heater capacities range from 100 to 500 liters. Small families may reasonably use a 150 LPH heater, a medium family may use a 300 LPH heater, and a big family may use a 450 LPH or 500 LPH instant solar water heater. When choosing solar water heaters, consider the size and kind of residence and the amount of power needed every day.

Opt for solar heated showers made of high-quality powder-coated MS or stainless steel to prevent corrosion. Collectors, storage tanks, and any exposed components should be built to withstand harsh weather without requiring extensive maintenance.

If a heater requires installation, choose one that is easy and quick to install. Check that it complies with local rules and laws. Select a heater that meets all applicable safety and quality standards, such as IEC and CE certifications.
