#2. Types of 100L Water Heater

To meet the different expectations of every individual efficiently, the solar market provides several kinds of 100L solar water heaters. Each kind has mastery in its specific field. You can choose the one that suits your area’s climatic conditions, latitudes and other needs. Besides, the types allow you to choose the best heater that can satisfy your budget as well. 

There are two types of solar water heaters available, first one is flat plate collector and the second one is evacuated tube collector.

The flat plate collector (FPC)-based system has a longer life than the evacuated tube collector (ETC) system because it uses a metallic box flat plate collector. FPC systems are available with and without a heat exchanger, and they can operate with or without a pressure pump (pressurized and non-pressurized).

The FPC solar water heater is further divided into 4 types-

    • Non Pressurized or Standard (NPX)
    • Pressurized (Px.)
    • Heat Exchanger (HE)
    • Pressurized with heat exchanger (Px. HE)

#3. ETC 100 Liter Water Heater

ETC stands for Evacuated Tube Collector; hence it has evacuated tubes as heat collectors. The ETC technology employs tubes made from double-layered borosilicate glass to heat the water. As the technology hit the solar market, it became the favourite choice of buyers. And why not when it demands less from the user while providing them more. It requires little roof space and minimum effort for installation along with low maintenance after installation. Still, it captures maximum sunlight, works effectively in all weather conditions and is tough and durable. Besides, an ETC 100 litre solar water heater is an incredibly efficient and advanced water heating technology.

How does an ETC solar water heater work?

The ETC solar water heaters have beds of tubes. The construction of the tubes is such that the transparent glass tubes enclose the metal absorber tubes inside. Between them is a vacuum to prevent heat loss. The sunlight or solar energy is absorbed by the metal absorber of the tube. As the water runs inside the tube, the heat from the outer wall gets transferred to the water inside the tube. And hence, the water gets heated.
