Important Factors to Look Forward Before Buying a Solar Water Heater

The Source of Water

Mainly you would have to examine the place where you live to get a better idea of water source. It’s one of the most crucial things to consider. So, firstly you need to discover if it is hard water or soft water, then you decide which is the best solar water heater for hard water.

There are two kinds of heating system: direct heating system and indirect heating system and because of these heating systems, we get to know which one suits the water type better.

There are hard water and soft water, the direct water heating system suits the soft water while the indirect heating system is more preferable for hard water. In a direct water heating system, the process of heating water is different from an indirect heating system.

The sun’s rays are absorbed by the solar water heater, and the water is heated immediately. While the indirect heating system contains a fluid that is later on heated by the panel and heats the water used in the house.

Functionality and Types

The overall functionality of a solar water heater is one of the essential components because it all relies on basic functionality. The solar collector has two different types, one is Flat Plate Collectors (FPC) and the other one is Evacuated Tubes Collectors (ETC).

The ETCS is made of two layers of transparent glass tubes, while the FPCS are metals like copper or aluminum.

Both of these water containers have their benefits and other working applicability. The FPCS are more suited for places with a warm environment because these types of Heaters have higher conductivity and reflectivity.

For this very reason, heat retainers used to low temperatures are not suitable for temperate regions. It’s easier for us to clean and do the overall service of FPCS because they’re strong and long-lasting.

On the other hand, ETCS are lighter than FPCS, these water heaters have high heating duration capacity. The ETCS are also suitable for both temperatures, the warm temperature, same as the temperature in the tropical areas and even temperate regions.

They’re made of transparent glass and are quite delicate. As a result, they must be treated with care and caution.

Size and Capacity

Size and capacity depend the most because you sort out where you would keep a solar water heater before buying it. It is quite equivalent to choose a solar water heater with a suitable size.

The best solar water heater system in India is selected with the count of family members. If we take out the overall LPD known as litre per day, if we see a person uses almost 30 litre a day, that person has the available water capacity of 30 litre.

If you want a solar heater that should cover up the water capacity of 3 people then 100 LPD would be perfect for a small family. If you have a small home space, then 200 or 150 LPD might do the job for you because it would be more than enough.

But if you have a family with several members, you might want to switch up the LTD. There are several solar water heaters in the commercial or industrial markets, from 500 LPD to 5000 LPD.

But the best solar water heater in India ranges between 100 LPD To 500 LPD.

Type of tank

Choosing the tank for your solar water heater is one of the important steps as well, as it should be durable, runner up, withstand heat, adequate capacity, eligible storage and so on.

The main purpose of the tank is to provide storage. If a tank is made well, with convenient space and thick walls, it can probably stand the heat for almost 60 hours. The tank should also be sustainable and made of a food safety grade material, protecting the water from releasing any unpleasant smell.

It should also be free from rust, and the pipes should be changed after some time before it rots.

You should also be well aware of the materials used in the tank to save it from corrosion. In most cases, tanks do have enamel coatings, which also help in the prevention of corrosion.

Water Pressure System

Before looking into the water pressure, have a look at your home. It is essential to examine the water flow and pressure in the house.

When we’re aware that the solar water heater will not get damaged if the water pressure at our home is normal. But if water’s force is at a higher rate than usual, it might damage the product.

You also have to know the types of pressure systems, as there are two types of the pressure system. The pressurized and the non-pressurized, in both these types having equilibrium, is outmost important because of the supply line in the solar water heater.

So, the right choice would be to get a Solar water heater that withstands a higher degree of water pressure. The water heater that can withstand the pressure of 8-10 Kpa is supreme and they’re a lot of solar water heater that have the potency.

They must also have other features, like heat exchange technology and the mechanism for fast heat recovery. These are some must-have, due to any situation that arises.

The time from morning till noon is the best time to get sunlight; you can approximate the time from 10 am to 4-5 pm.

Plumbing Work

It is most necessary to get the plumbing done professionally so your solar water heater is safe. If somehow there’s something wrong with the installation, it might damage the device completely.

Many plumbers are not aware of the installation system and the involvement two-pipping mechanism. You might know that two pipes separate the hot and the cold water and this very mechanism is known as the two-piping mechanism.

The two-piping mechanism is mostly used in the bathroom and kitchen. There is a tube that ensures the water to be heated quickly and it is economical.

Service Life

And you also have to know about the warranty offer, if it lasts long or not. Some of the best solar water heater sellers make sure that they give you a warranty of 5 years.

A solar water heater can last for 15 years if you have maintained it well along the time. Before buying a solar water heater, look at the description and the other information that comes with it.

Temperature Regulation

The solar water heater you want to buy should have the feature of an inbuilt thermostat. The inbuilt thermostat should have sufficient capacity to manage the temperature well and keep it between 60-70 degrees Celsius.

This is to avoid the water getting so overheated that it might damage the skin or worst case scenario it might destroy tissue and cells. These are just some preventive measures that should consider with priority.


Maintenance is the key to a long-lasting and well-operated solar water heater. It would be best if you kept everything that is connected to the solar water heater maintained. Keep track of the pipes, tank, panels etc.

You also keep the water in check if the flow is well required. The process of cold water turning hot should also be examined, whether the water is clean or not.
