Types of Solar Water Heaters in India

Types of Solar Water Heater System

A solar water heater is a unique category of geysers that utilizes sun rays to function. These are widely preferred for their low cost of operation and eco-friendly nature. As solar water heaters barely consume electricity, they enable huge amount of savings. In fact, Racold’s solar water geysers can provide up to 80 percent savings.

Now, solar water geysers can further be classified into various types. Each type has a distinct functionality and it can be a little tricky to identify which one suits your needs. That is why, we have put up this blog to help you explore different types of solar water heaters and how they are beneficial to you. We will also introduce you to some of the best solar water heaters in India.

Introduction to the solar water heaters

A solar hot water heater is generally installed on the roof. It consists of collectors facing the sun to absorb solar radiations. As initial part of the process, the cold water enters the vacuum collector tube. Here, it gets heated by the solar energy absorbed by the collector. As the temperature increases, water begins to rise up. Now it enters an insulated tank that can store hot water for long durations. Due to the insulation, heat loss is prevented and water remains hot even when it used much later. And that’s how a collector based solar water geyser operates!

In this section, we will explain the different types of solar water heating systems in detail. Read on to learn more:

Flat plate collector (FPC)

FPCs are the most popular type of collectors. They consist of a rectangular box that is insulated. This box is covered by a glass. Just beneath the glass, there are a series of interconnected copper pipes for the water to flow through. Since it is metallic, this system is more durable. Additionally, we incorporate an Enamel Coating in our Omega range of solar water heaters to prevent corrosion and ensure a longer lifespan. The Omega range has been designed to withstand High Pressure and to exhibit high performance. Its 4 in 1 Multifunction Valve makes it completely safe for domestic usage.

Evacuated Tube Collectors (ETC)

Evacuated tube collectors employ glass tubes to absorb solar radiations. The core ideology behind this solar hot water system is that vacuum is an effective insulator. A tube called 3T has multiple layers and vacuum is trapped in between them. In our Alpha range of solar geysers, the inner tank is coated with PUF Insulation for higher efficiency. These geysers also employ Magnesium Anode to improve durability and ensure that you rest assured for many years. However, the most impressive thing in our Alpha Pro is a technological advancement that includes Smart Float Technology. It is a unique valve designed and patented by Racold to prevent long air vents and encourage safe usage.
