Solar Water Heaters Buying Guide

Types of Solar Water Heaters

There are two types of Solar Water Heaters:

Active Systems-

Active Systems comes in two types- Direct Circulation Systems and Indirect Circulation Systems.

The Direct Circulation Systems are ideal for the places where temperature doesn’t follow below zero. It pumps the household water through collectors which is then delivered in your house for use. These units come with the automatic controllers to sense the sunlight.

On the other hand, Indirect Circulation Systems functions well in temperatures below zero. But these units are expensive. These units heat the water by pumping it through a heat transfer fluid and then delivered through the collectors and a heat exchanger.

Passive Systems-

The passive systems are also available in two types- Integral Collector-Storage Passive Systems and Thermosyphon Systems.

The Integral Collector Storage Systems come with the storage tank, solar collection unit, and pipes that pump cold water into the collector. And therefore an ideal option for the households with significant water needs. These units are ideal for the areas where temperature doesn’t fall below zero.

While Thermosyphon systems are the most reliable one and great for the households with strong hot water needs. These units are also expensive and work well in the area where temperature falls below zero.

Pros and Cons of Solar Water Heaters

The Good

  • Efficient and reliable source of water heating
  • Reduces the electricity bills as it uses solar energy to heat up the water
  • Environment-friendly
  • Renewable and clean source of energy
  • Easy to install and requires a little maintenance
  • One time investment to install them and it works approx 20-30 years without creating any trouble
The Bad

Features to consider before buying a Solar Water Heater for your home

Geographic Location

Your geographic location is an important aspect before purchasing a solar water heater. Solar water heaters work only when they receive the direct sunlight. So, if you are living in an area closest to the equator, the unit really works very well. But the locations where there is a lack of sunlight, don’t go for the solar water heaters.

Size and Capacity

Opting for the big size is an ideal option if you have enough space on your roof for its installation.

Storage capacity is also an important consideration. To cater the hot water need for a small family with 3-4 people, a 50- to 60-gallon storage tank is fine. But for the large family, it is great to choose the one having the 80-gallon tank or more.

Type and Functionality

There comes the two types of solar collectors- The Flat Plate Collectors and Evacuated Tube Collectors. The FPC is made up of copper or aluminum metals and are quite bulky in size and also the expensive ones. With the features consisting of robustness, durability, and easy maintenance, these are ideal for the tropical climates. And on the other hand, ETC have high heat retention capacity that makes it suitable for both tropical and temperate regions. But since these are made up of glass, proper handling is required during installation, servicing and operation.

Type of tank used

Always go for the solar water heaters with the thick tank to store the heated water. It is also important to check that the tank should have enough capacity to retain heat for at least 60-72 hours.

Brand

Always go for the branded solar heaters that have certification standards. Since it is an expensive deal to purchase and install a solar water heater, it must be a good quality product so that you can use it for the long run.

    1. Hi Prasant,
      There is no Geyser in the market that take power from solar energy directly. You can only use Solar water heater that can be mounted on top of your roof. This is little costlier (Starting from 16000 Rs and above). According to us brand like Supreme, Recold, olex and AWCRE are best.
      Just buy the first one mention in above list (Recold)

      Before you purchase make sure
      1. It can be delivered to your location
      2. Customer care is willing to help you and send engineer for instillation
      3. You have enough space on your roof top
      4. There is direct sunlight on your root top

      Hope this help.

  1. Hi,
    I am planning to buy Solar water heater with budget Rs 20000.Can you please suggest me some good one for Bangalore climate.
    Looking for 200 LTR( 5 family members).
    What things i have to consider before buying.
    Thanks,
    Venkat

    1. Among these brands our top choices are Supreme ( https://amzn.to/2rO7Cx3 ) and Racold.
      No 1 thing is locate the nearest customer service center and ask for installation charges, Ask for warranty period, Does it have electric backup?
      Hope this help
