In this blog, you’ll learn about the types of solar water heater systems available, how they work, and which one might be perfect for you!

Understanding Solar Water Heating Systems

How Do Solar Water Heating Systems Work?

A solar water heating system uses energy from the sun to heat water. The system typically includes solar hot water panels (also known as solar collectors), a solar water heater tank, and sometimes an electric or gas booster for backup heating. Whether you have a solar water heater 100 ltr price setup or a solar water heater 200 litre price system, they all operate on the same basic principle—harnessing sunlight for efficient water heating.

Now, let's dive into what types of solar hot water heat are there, so you can decide which is best for your home or business.

The Main Types of Solar Water Heaters

There are two main categories of solar water heater systems: Active (pumped) and Passive (natural circulation). Each type has sub-categories, which we’ll explain below.

1. Active Solar Water Heater Systems

Active systems use pumps and controllers to circulate water or heat-transfer fluids through the system.

a) Direct Active Systems

In a direct system, water is pumped directly through the solar hot water panels where it gets heated and then sent to your solar water heater tank. These are common in areas where freezing temperatures are not a problem, like Maharashtra or Mysore.

b) Indirect Active Systems

In an indirect system, a heat-transfer fluid (usually antifreeze) is heated in the collectors and then passes through a heat exchanger to warm the water in your storage tank. This type prevents freezing, making it ideal for colder regions.

Common in Varistor Solar products for colder regions

2. Passive Solar Water Heater Systems

Passive systems don't use pumps. Instead, they rely on gravity and natural circulation to move water.

a) Thermosiphon Systems

These systems have solar hot water panels installed lower than the solar water heater tank, allowing heated water to rise naturally into the storage tank. Simple and reliable, they are often used in solar heater for home setups.

Great for warmer regions like Mumbai and Bangalore (solar water heater in bangalore price systems)

b) Integral Collector Storage (ICS) Systems

In ICS systems, water is heated directly inside large tubes or tanks placed in the solar hot water panels. These are great for mild climates and homes with lower hot water needs.

Simple design, easy installation
Reliable with fewer maintenance requirements

Flat Plate Collectors (FPC) vs. Evacuated Tube Collectors (ETC)

Now that you know the two main system types, you might ask: Which type of solar hot water heat collector is best?Let’s break it down.

Flat Plate Collectors (FPC)

These are the traditional solar hot water panels, consisting of an insulated box with a dark absorber plate and a transparent cover.

Durable and time-tested
Best for solar geyser installations in moderate climates

Evacuated Tube Collectors (ETC)

ETCs use multiple glass tubes to absorb and retain heat efficiently. They perform well in both warm and cold climates.

More efficient in low sunlight

Popular for solar heater for home systems and solar water heater in hospital

Choosing the Best Solar Water Heater for You

Factors to Consider

Before choosing a system, consider these factors:

Climate (cold vs. hot)
