Water Heater Buying Guide – 2020

India is famous for its extreme weather conditions; as we are well versed with the changing temperatures, it’s always better to be fully equipped to sustain these climate changes.

Although we love the winter season, we should definitely hand it down to the man who invented water heaters to help us shower in the cold, chilling winters of India. The rattling of teeth and the shivering body can only be stopped by a warm, relaxing bath. That’s where our hero, “water heater” comes in.

While buying a water heater there are some basic questions which cross your mind, don’t worry we’ve got it covered.

Want to know how a water heater works?

A typical Electrical water heater works on a simple mechanism, a electric heating unit is connected to a 220- volt circuit. To warm up the water, the current is allowed to pass through a certain electrical-resistant heating element which is fixed in the middle of the tank. Power is delivered through a thermostat, which controls the water temperature.

We have a new way of getting hot water without worrying about the increasing electricity charges i.e. Solar water heater. The solar water heating system works on the principle of the thermosyphon process and forced circulation. It uses Solar energy and can give up to 50-70C * hot water. The core of an ETC Solar water heater is a solar collector basically in the form of tubes and a storage tank. The evacuated tube acts as an absorber in the solar water heater and an evacuated tube consists of two glass tubes having a vacuum in between which is an excellent insulator. The incident solar radiation falling on the tube passes through the outer transparent tube and strikes the outer surface of the inner tube. It absorbs heat energy and then passes to the cold water flowing in the tube. Thus a solar collector is one that turns the sun’s radiation into heat. A storage tank is exactly what it sounds like; It holds the water. An evacuated tube technology based solar water heating system is the most energy-efficient and cost-effective.

What are the types of water heaters available in the market?

What specific factors should you consider while buying a water heater?

Buying a water heater is no rocket science, but there are some specific factors that one needs to remember while investing in one.

a) Size of the family

Your daily water requirement is one of the main factors that should decide the capacity of your water heater. Given below is a rough idea of the capacities required for average use. Please note that this is indicative as capacities vary according to water usage patterns, inlet water temperature, and weather conditions.

Capacity Criteria

15L 1 – 2 person per bathroom in a cold climatic location
15L or more 3 – 4 person per bathroom
25L 3 – 4 person per bathroom in a cold climatic location
35L or more More than 4 people, bathtubs
Instant water heater Kitchen, mild hot water requirement

b) Energy efficiency

Energy efficiency products are good for your pockets and our environment. So, it’s a smart option to go with water heaters which are less power consuming and highly efficient. The energy efficiency of the water heater is indicated by its energy star rating i.e. higher the rating, the higher the energy efficiency of the product.

c) After-sales service

Water heaters are sensitive appliances and must be taken care of and maintained regularly. It is very important to have good after-sales service support to repair the geysers in case of damage.

d) Water type

Many people underestimate the damage caused by hard water to your water heaters. Hard water contains high levels of mineral salts like calcium and magnesium. The minerals present in hard water can cause scaling. Over a period of time, this starts interfering with the efficiency of the water heaters.

e) Pressure pump compatibility

Pressure pump applications for water heaters are required in case of high rise building. Most water heaters available in the market are prone to leak when exposed to high water pressure. Bajaj’s range of water heaters has high pressure withstanding capacity (up to 8kg/cm2) which ensures that they are pressure pump/high rise building compatibility.
