Geysers Buying Guide

Tank Type Water Heaters

Tank type water heatersare normally used in homes. They have a large, cylindrical tank standing on the end with pipes that are attached to them. If you don’t have a tank but have a hot-water heating system for heating, it’s possible that hot water reaching your tap will be heated by the boiler. In other circumstances, hot water can be supplied by a stand-alone instantaneous water heater which is mounted near the fixture it serves. The normal water heaters are of two types- Electric and Fuel-Fired. In the case of the latter, the fuel normally used in gas, either propane or natural.

Fuel-fired unitscome with a vent pipe at the top for carrying away exhaust gasses. In contrast, electric modelsare only equipped with a power cable which connects the heater to the electric service panel. At Moglix, we are offering water heaters from brands such as Eveready , Marc , Bajaj , Venus etc. The primary task of the tank-type heater is not only for heating the water but also storing it till it’s ready for usage. Additionally, all tanks are equipped with insulation for maintaining the warmth of water during heating rounds. The upper part of every tank is equipped with a water supply and delivery pipes. The supply pipe water moves cold water to the bottom of the tank through the dip tube. The hot-water delivery pipe takes water from the top.

To ensure safety, all water heaters have a T & P valve ( temperature and pressure relief valve). The valve opens if either the temperature or pressure of water exceeds a safety limit. The valve is connected to a pipe which runs outside the tank and ends 6 inches from the floor. It’s wise to keep a bucket under the pipe end to catch water if the valve opens. The T & P valve shouldn’t be connected to a drain. In case the valve did open, there is a sign that such an issue within the water heater.

Most of the tanks are made from steel and are glass-lined in the interior to check corrosion. Corrosion is the major reason why tanks fail. Once the rust creates a hole, there are momentary fixes. However, the tank needs to be replaced in the long run. All tanks are equipped with an anode rod for controlling corrosion. The tanks are protected by the magnesium anode rod by corroding the tank in place of steel. Since the rod is designed to corrode, it will eventually wear away.

Once this happens, the corrosion of steel will speed up. It’s wise to check the anode rod once annually and replace it if is necessary. At the bottom of the tank, there is a drain cock for an emptying heater. The valve on supply pipe enables you to shut down the hot-water plumbing without affecting the home’s cold-water supply.

Geysers

Storage/Tanker Geyser

A storage/tanker is a tank which is used for storing hot water. There are different sizes of tank measures in liters. You will need to decide on the capacity based on the usage. These geysers are normally big in size and require more space for installation.

Tank Less Geyser

As its name suggest, there will be no tank for water storage. Rather water will be heated instantly. There is a very slow in water outflow based on installation.

Electric Geyser

They utilize electricity for heating water. These geysers utilize electricity for water heaters. Storing a large amount of water even when it is not necessary to ensure that wastage of power is high.

Gas Geysers

This type of geysers is cheaper as compared to electronic geysers but they need to very careful about chances of gas leakage. While using geysers, there is no need for water storage. Solar geysers prove to be quite cheaper in the long run but include high investments in the long run.

How Do Electronic Geysers Work?

Geysers have three major components- Heating Element, Water Tanks, and Thermostats. Each of these components is explained below: -

Geyser Heating Element

The heating element is a vital component of the geyser, apart from the container or inner tank. Therefore, you will need to inspect the quality of the geyser element. Extremely hard and very soft water affects heating elements, like the inner tank. The geyser’s heating elements are coated with a glass lining which is high effective for checking scaling. It also increases the durability of the geysers.

Geyser Water Tanks

Geyser tanks hold hot water. Therefore, tanks need to be corrosion resistant and strong. There are two types of Geyser water tanks: -

• The older models are made from stainless steel and have become obsolete now. Corrosion and hard water scaling are the major problems with these water tanks.
• Vitreous enamel glass coated geyser water tanks are the latest models in geyser technology. During the manufacturing process, the stainless steel water tank is coated with advanced polymers to make the tank corrosion resistant. This mixture is known as Vitreous Enamel glass coated geyser water tank. They are corrosion resistant and can help in hard water scaling also. Vitreous Enamel water tanks usually come with 5-7 years’ warranty also. It is quite similar to glass lined coating.

Geyser Thermostat

The geyser thermostat is the operating system of a geyser. It decides when to start and stop the heating of water. A bimetallic strip is utilised for converting a temperature change into mechanical displacement. The bimetallic strip is made from steel and copper. The thermostat is a wrapper on this strip which takes the action on the bimetallic strip response. A high-quality thermostat protects the geyser from overheating of water. It also helps in saving power consumption to an extent, but partially. Users normally have a misconception that they do not need to switch off the geyser because they have a thermostat. The thermostat has a temperature range between 30-60 ℃ for heating water.

Thermostats have a dial to set the maximum water temperature-usually between 130 ℉ or as low as 120 ℉ for higher energy savings and scald protection. Once a hot-water tap is opened, cold water enters the tank through the dip tube and drops in temperature initiates the thermostat at element at the bottom. As water at the tank’s top is substituted by cool water, the temperature at the thermostat top drops and exits. Once the tap is turned off, the heating elements continue carrying currents till the thermostats are satisfied.

Effectiveness of A Geyser

Since water heaters heat as well as store water, the rate of water heating and capacity of the tank affects the supply of water at your fittings. The speed at which the water heats is known as its recovery rate. Once you draw water faster than it is heated, there is a drop in temperature. However, since the tank stores hot water, its capacity also affects the constant water availability at the tap.

How to Select Geysers?

Selecting a water heater with proper capacity and recovery rate depends on the level of your water usage and how your unit heats the water. Typically, heaters with low recovery rates are equipped with a high tank capacity. Though it takes longer to heat the water, there is more of it for periodic use. Electric heaters fall within this category. I contrast, a fuel-hired heater with a high recovery rate doesn’t require a large tank since it can heat water quickly. Normally electric models have the lowest recovery rate. In contrast, oil-fired units have the highest.

Here are some of the major factors you should pay attention to while selecting a water heater/geyser: -

Electricity Consumption by The Geyser

• The volume of hot water being used- This is the major driving factor of electricity consumption by water heaters. The greater the amount of hot water you utilise, the greater the electricity it will consume.
• The temperature of water used for bathing- This is different from thermostat temperature.
• Tap(Input)water temperature- Regions with colder climates need far more heating as compared to places with warmer climates. A water heater in Himachal Pradesh will require far more electricity than its counterpart in Kerala.
• Thermostat temperature- The thermostat temperature by default is set at about 60 ° C for most water heaters. Some water heaters provide external control to change the settings as well.
• Standing Losses- Water heaters don’t lose heat since it is calculated as standing loss. It is the heat lost through the water heater’s surface. BEE (Bureau of Energy Efficiency) describes standing losses as the energy consumption of a filled water heater post steady-state conditions have been reached when water isn’t drawn. The quality of the material is a major factor necessary for making the water heater. Water heaters from leading brands are of high quality and therefore they are preferred. BEE rates only branded water heaters.

How Much Water is Required by The Family?

• For bathing, utilise bucket water. Each person requires 15 liters per bath. If you have a family, then add 15 liters per bucket.
• For taking a bath using shower-25 liters/per person per bath.
• To wash clothes-10 liters/person per day.
• To wash utensils-5 liters/person per meal.
• What is the ideal temperature for bathing?

Though most water heaters have a thermostat setting of 60 ℃. But water at 60 ℃ is far too lethal for the human body and can cause first-degree burns. The normal human body temperature is 37℃ and any temperature above it will make you feel hot. If you boil water at 46 ℃, you will have to add extra cold water to make it bearable.

Will All Water Heaters Consume Ideal Units of Electricity?

No!The amount of water calculated above are ideal and not actual units. The actual units depend on the water heater size, standing losses and the way you utilise it. The greater the size of a water heater the higher will be the losses since it will cover a greater surface area. Normally 100-liters’ water heaters have a standing loss greater than 1 unit per day. 70 liters’ water heaters have a standing loss close to 0.9 units per day. The lesser the size of the water heater, the lesser will be the standing loss.

If the water heater is kept on throughout the day, you will surely lose the full standing loss units in a day. One way of minimising it is by heating the amount of water you require and switching the water heater on before use usage. Make sure that it is switched off after use. Ensure that there is no wastage of any extra hot water since that is a waste of electricity.

What Is the Ideal Size of a Geyser?

A geyser’s ideal size needs to be close to the volume of hot water necessary at one go. If your water heater is connected with 2 bathrooms, then the ideal size is 50 liters. Ideally, sized heat generators are the ones which generate sufficient heat are suitable for maximum immediate use.

How to Install a Geyser?

It’s wise to avoid calling a local plumber for installation if he doesn’t follow the best practices and safety guidelines. Instead, install the geyser with the help of an authorised service center. Most geyser manufacturers offer installation service. You will require some additional thigs such as two steel ribbed pipes, one angle valve brass, a single connection nipple and another staff.

What Is the Wattage?

One vital factor which you will need to keep in mind while selecting a geyser is its wattage. A geyser’s wattage makes it faster or slower. The water heats quickly if you use an immediate geyser of 4.5 kW instantaneous geyser unlike a geyser of 2 kW. In some instances, 4.5 kW instantaneous geysers can save electricity and heat water required for bathing by ending the wastage of more hot water.

How to Reduce Geyser Electricity Consumption?

While buying a geyser, you need to check BEE (Bureau of Energy Efficiency) star ratings and opt for the best-rated geysers. Here are some useful geyser usage guidelines: -

• Standing Losses - Standing losses refer to the heat lost through the geyser’s surface. Geysers lose heat which is regarded as standing losses.
• The volume of utilised hot water heater – This is the main motivating factor of a geyser’s usage of power. The greater the amount of hot water you use, the more will be the power usage.
• The temperature of the Geyser Thermostat - It is determined by default which set to around 60 ℃ for most of the available geysers. However, a number of geysers come with an external control for modifying the setting.
• The Temperature of Water Utilised for Bathing - Your level of geyser electricity consumption is also determined by water’s temperature that is used for bathing. It is quite different from a thermostat’s temperature.
• Input Water Temperature - Input water temperature is determined by location. Areas with colder weather need more electricity as compared to places with a warm climate.
