Therefore, how to choose the perfect geyser home?
To understand this, you need to understand the geyser types, the convenience of each type, and how it can meet your family's needs. As there are too many options available in the market, it can be overwhelming to pick the right one that will be highly efficient, well-maintainable, and save you money. Henceforth, ready to dive in for details? Let's explore together!
Understanding the Different Types of Geysers
Before delving into the details of the water heater buying guide, let's know about the different types of geysers available in the market, so you can get a clearer picture.
1. Storage Geysers
Storage geysers are the most common type of geyser used in households. As the name suggests, this type of geyser has a tank that stores heated water. This is perfect for a family because it holds a steady flow of water in multiple locations like the bathroom or kitchen. Even if electricity isn’t available temporarily, you can still use the hot water from the storage.
Pros
-
Available in various sizes (6-35 liters or more)
-
Ideal for family usage.
-
Has multiple outlets.
Cons
-
As there's an extra storage tank, it needs more space.
-
Higher energy consumption.
2. Instant Geysers
Unlike storage geysers, instant geysers are tankless water heaters. Just as the name suggests, these geysers heat water almost immediately after switching the power on. They're highly energy efficient as they don't need to keep the water heated always. Instant geysers are ideal for small families who need a quick hot water supply in limited quantities.
Pros
-
Space saving as there's no extra tank.
-
Energy efficient as water is heated when on demand.
Cons
-
Limited capacity like 1-3 liters.
-
Not ideal for big households.
3. Solar Geysers
Solar water heaters use sunlight to heat water making them one of the highly energy-efficient and eco-friendly options. However, this type of geyser is suitable where there's enough sunlight to heat water. Even though installing this geyser at first will be costly, it'll be cost-effective in the long run.
Pros
-
Lowers electricity bills in significant amounts.
-
Environment friendly.
-
Low maintenance.
Cons
-
It requires sufficient rooftop space to install.
-
Based on the weather, the heating can vary.
4. Gas Geysers
Just as the name suggests, the gas geysers use LPG(Liquefied Petroleum Gas) or natural gas to heat water. These types of geysers are extremely energy-efficient and cost-effective for larger families. Where electricity supply is expensive, gas geysers are extremely ideal for those areas.
Pros
-
Energy and cost-effectiveness.
-
Heats water faster than electric ones.
Cons
-
Installation requires a gas pipeline or cylinder.
-
Needs proper ventilation to avoid gas leaks or carbon monoxide building up.
Factors to Consider When Choosing a Geyser


Now that we're familiar with all types of geysers in the market, it's time to understand the key factors that we must keep in mind before thinking “How to choose a geyser?”-
Capacity Consideration
One of the most crucial things you need to check while choosing a geyser size for your home is the capacity. Without wasting energy when it can meet your family's hot water demand, that's what is called an energy-efficient water heater. The right size can be determined by the family members and their daily demand for hot water. Here's a simple table to make the capacity chart clearer-
Household Members |
Recommended Capacity |
1-2 members |
6-10 liters |
3-4 members |
15-25 liters |
5+ members |
35-50 liters |
Note: Always choose a slightly larger geyser size if you have frequent guests.
Safety Features
When choosing a geyser safety features are important to consider. If not maintained properly, the geyser can cause disaster in your household. Therefore some safety features are mentioned here-
-
Pressure Release Valves(PRV): It ensures that after heating water the high water pressure doesn’t build up inside the tank which can lead to explosions.
-
Thermostat Control: It prevents water from overheating, which can lead to extreme energy consumption. So, when the desired temperature is reached, the thermostat control cuts off the power automatically.
-
Auto Shut-off: It turns off the geyser automatically when there's no water inside the tank, so the tank doesn't go dry or damaged.
-
Anti-Corrosion Coating: It ensures the longevity of the geyser and prevents tank damage. It protects the internal components from hard water.
Power Consumption
Given the increasing rate of electricity, you'll need an energy-efficient geyser for the long term. Check in online for the BEE(Bureau of Energy Efficiency) ratings. The 5-star Geyser energy ratings geyser will consume less power. That's why look for geysers with 5 stars to save monthly electricity bills. Also, some models come with insulation to reduce heat loss.
Maintenance & Durability
Get a geyser which will need minimum maintenance cost. Make sure to look for geysers made with stainless steel or glass-coated that can prevent corrosion or internal buildup. In addition, cleaning the inside tank periodically is a wise idea. Change the anode rod, that prevents corrosion, if it wears out.
Energy Source Options
Here are the energy source options available in geysers-
-
Electric Geysers: This type consumes power, is easy to install, and leads to higher electricity bills. Comes in tank or tankless varieties.
-
Gas Geysers: This type consumes LPG or natural gas, is less costly than electric ones, and needs regular maintenance for gas leakage.
-
Solar Geysers: The best eco-friendly option which uses sunlight, at zero extra cost. However, the performance depends on the weather.
Energy-saving Technologies
Nowadays modern geysers come with some marvelous energy-saving technologies. Such as-
-
Thermostat: Always keep the temperature of the thermostat in between 50°C- 60°C. It'll maintain the optimal water temperature without wasting extra electricity.
-
Timer Settings: It automatically shuts the geyser off after a specific time.
-
Heat Retention Tanks: The tanks which are insulated, reduce heat loss and keep the water hot for a longer period.
Temperature Control
In smart geysers, temperature control is an essential feature that allows users to adjust the timer and temperature according to their comfort. Some advanced models even come with digital displays and times that can enable you to set the geyser to turn on at a specific time.
Budget & Installation Costs
Depending on the type, capacity and smart features the cost of the geyser depends. In your budget, you must take in the main cost along with the water heater installation cost.
Electric geysers are more affordable at first glance, but as time goes the electricity bills will rise higher. Whereas, gas and solar geysers have higher initial costs but later they’ll save you money for the lower energy consumption.
How to Determine Your Hot Water Needs?
Before purchasing your geyser, make sure to calculate the hot water demand of your family. Here's how you do it-
Family Members & Using Pattern
Get the family members of your house and their daily hot water demand. Larger families will need larger capacity geysers whereas single/couples may find instant geysers more sufficient. For using a pattern-
-
Bathing
-
Kitchen usage
-
Laundry necessary
Weather Consideration
If you live in a colder region, a larger capacity or high-wattage geyser is necessary to heat water efficiently whereas in warmer areas smaller capacity or solar geysers will work well.
