2. Mandhata Inventions 200 LPD ETC Solar Water Heater
The inner tank of this solar water heater is composed of stainless steel that help provide more strength and durability to the design. This solar geyser has a sacrificial anode rod that uses multi-crystalline solar cells to help reduce salty water. This solar water geyser can hold upto 200L of water and works best for 4-6 members of the family.
3. Racold Alpha Pro Solar 100 LPD Domestic Water Heater
Made using Duronox, the material that is known to provide resistance and durability to the water heater while preventing the corrosion in the tanks and pipes. This domestic solar water heater works best for windy areas as it comes in the form of float valves and it also minimises the long air vents to keep water warm for long hours and provide safe usage.
4. Solarizer Spring AV Solar Water Heater
This solar water heater is made with low carbon steel, glass enamel coating and a flat plate collector of copper tubes that offers efficiency when it comes to handling medium hard water. The plates are tempered that help prevent breakages that may occur due to minor causes.
Storage Tanks and Solar Collectors
Solar water heaters mostly require a well-insulated storage tank that have an additional outlet and inlet connected to the collector. The solar heater that comes with two-tank system, preheats the water before it enters the conventional water heater. Whereas, in the one-tank systems, the back-up heater combines with the solar storage in one tank.
There are three types of solar collectors:
Flat-plate collector: Flat-plate collectors are insulated, weather-proof boxes that has a dark absorber plate under one or more plastic (polymer) or glass covers and are usually glazed. The unglazed flat-plate collectors are mainlyt used for solar pool heating purpose as it has a dark absorber plate, made of metal or polymer, without a cover or enclosure.
Integral collector-storage systems: Also known as batch systems or ICS, they feature one or more black tubes or tanks or in a glazed insulated box. Cold water passes enters the solar collector to preheat and then the water passes on to the conventional backup water heater to provide you hot water. These are best for the mild-freeze climates as water in the outdoor pipes could freeze in extremely cold weather.
Evacuated-tube solar collectors: They come with parallel rows of transparent glass tubes in which each tube contains a glass outer tube along with metal absorber tube that is attached to a fin. The solar energy gets absorbed by the fin's coating but prevents radiative heat loss. These solar collectors are best used for U.S. commercial applications.
Solar water heating systems should have a backup system for cloudy days and conventional storage water heaters are usually used as backup or these maybe a part of the solar water heater system package.
