How does an Instant Water Heater work?

Instant water heaters have a microprocessor built into them which controls the functioning of the heater. Microprocessors have introduced automation into the heaters which require minimal input and handling from the user. Microprocessors have sensors which determine the temperature and control the flow of water. Instant water heaters operate on either electricity or gas.

Components 

  • Microprocessor – It controls the overall functioning of the heater.
  • Flow Sensor – Flow sensor is used to detect water flow in the heater which signals the microprocessor about the presence of water in the unit.
  • Burner – Burner is used for supplying heat to the heat exchanger.
  • Gas Inlet – Gas inlet is the point of entry of the gas into the burner.
  • Fan – Fan is used to keep the burner ignited until the operation is completed.
  • Heat Exchanger – The section in which the water is heated and then transported to tap.

Working of an instant water heater 

  • The output tap or faucet is opened, and the cold water enters the heater through the inlet valve.
  • This triggers the flow sensor present on the microprocessor, and the sensor starts administering the water flow.
  • The computer automatically starts up the heating unit which heats the water.
  • The water is circulated through the heat exchanger.
  • The heat exchanger heats the water to a predetermined temperature.
  • The hot water flows through the output valve.
  • The heater continues to operate until the output faucet is closed and shuts down after the flow sensor detects an inactive water flow.

Gas or Electric Instant Water Heaters?

FeatureElectric HeaterGas Heater
CostInitial cost is higher than gas models.Less expensive.
HeatingUses electricity to heat the water.Uses gas to heat the water.
Waiting TimeWaiting time is higher.Minimal waiting time due to direct contact with flame.
SpaceVery compact.Requires additional space for gas supply.
InstallationReasonably easy because only continuous electricity and water supply are needed.Cumbersome as it requires direct gas supply in addition to water and electricity.
PollutionNon-polluting product.Releases gases which may contribute to air pollution.
MaintenancewLess expensive because only the heater needs to be taken care of.More expensive because the gas supply device and ventilation need attention after regular usage.

So, the gas models are inexpensive and perform slightly better than electrical ones. But the maintenance and safety concerns make it a less preferred choice.

In addition to that gas supply is not readily available to most of the cities in our country. Moreover, LPG is a depleting source of energy, and its cost has continuously gone up in the last five years. So, we advise you to go over these facts before making a purchase.

Advantages of using Instant Water Heaters over Storage Tank

The waiting time in the instant water heater is minimal as compared to storage tank heaters where the water has to be stored for a time interval as specified by the manufacturer.

They are lighter than storage tank heaters because no space is needed to store water.

They are compact and can be easily mounted on walls.

They are 24%-35% more energy-efficient than storage tank heaters.

The durability is comparatively higher in instant water heater and can last up to 5-10years more than storage tank heaters.

It is correct that the instant water heating models are far more superior when it comes to delivering hot water to your faucet without wasting time. But the flow rate, especially in lower-end models, is very slow and displeasing. The higher-end models are very good at supplying hot water and have a decent flow rate.

So a new category of instant water heaters has emerged in the market which have a very small storage tank and can heat water in a very small time. The waiting time is a little longer in these heaters when compared to the tankless models. But the overall water dispensed in a minute a bit higher in tank models.

The lower-end models in the tankless category have a lesser flow rate and are not a good choice when your water needs are much higher. Tank models are an intelligent choice in such scenarios which can deliver as per your needs. These are a good alternative if you can manage to wait for some time before you can use it.

So if you can deal with waiting time and sedimentation accumulation at the bottom of the tank, they are your perfect alternative to tankless water heaters.

How to minimize electricity consumption?

Electricity costs could pile-up if you do not pay attention to your heaters operation time.Before buying any heater check for BEE(Bureau of Energy Efficiency) rating on the product. BEE is an energy rating standard and is used for benchmarking the efficiency of a product.

BEE rating is given in the form of stars. Products rated 3 and above out of five stars are considered to be more energy efficient. Apart from BEE rating, selecting a heater by wattage and operating voltage should also be considered.

The heater selection should be made according to the family’s size. A small family of four may not require a heater of high wattage because of its overwhelming power and capacity which would not be put to good use under normal circumstances.

Maintaining a low flow while using hot water puts very low stress on the heater and consumes less electricity. Do not run the heater at full throttle at all times. The output faucet should be closer to the heater because heat is lost when water has to travel through long pipes. These are a few things to keep in mind to save more on your electricity bill.

Types of Water Heaters

Storage Tank (Conventional Model)

Storage tank water heaters are the ones commonly found in households. These are based on the most primitive type of water heating technique which is collecting it in a vessel and then subjecting it to a heating mechanism.

The heating mechanism is mostly electric these days, but gas models are also present. They have to be filled with water with an inlet pipe and take a longer time to heat the water present inside it. The heated water then can be drained through an outlet pipe which is connected to a tap.

Tank-less (Instant Heating Model)

Tank-less water heaters are the makeover that conventional models desperately needed to appeal to the diverse consumer market. The idea is to apply the heating mechanism to the incoming water as it passed through the heating channel. They operate on electricity as well as gas. The continuous flow of hot water is maintained and flows at a steady rate through the outlet pipe.

Solar (Rooftop Model)

Solar water heaters as the name suggest using solar energy to heat water. The mechanism consists of solar panels which house hollow tubes of copper in a coil structure. The water flows into the coil through one end, heats up and then becomes lighter. The heated water flows into the storage tank through the inlet pipe of the tank, and the tubes are filled with cold water again. This happens simultaneously and does not exhaust any non-renewable resources.

Heat Pump (Hybrid)

The heat pump is a hybrid model and absorbs heat from air or ground to heat water. They are mostly employed in industrial spaces and require precise environments to cater to hot water needs.

A heat pump requires 60% less electricity than traditional water heaters. It is cost-effective in the long run.

As the heat is used from the ground, it is not suitable for cold regions, and also it is expensive as compared to other types.

Water Heater Buyer’s Guide

Size

Size is an important attribute when considering a water heater. Size in instant water heaters is directly proportional to flow rate. The flow rate is the rate at which hot water flows from the heater to the desired outlet.

The flow rate is higher in gas models as compared to electrical models due to direct exposure of heating channel to a high-intensity burner flame.

Sizing is also necessary to determine the workload that your water heater will be burdened with to give you an accurate idea of the flow rate. Moreover, as the number of outlet points increases water heater has to operate on full-blast to meet the requirements of the user.

Therefore there is a significant difference in the size of heaters required by a nuclear family as compared to a joint one.

Temperature

Instant water heaters are predominantly based on two types of fuel-sources namely- electricity and gas. Natural gas as a fuel alternative is a tricky proposition in India, so electricity models entice a higher section of the population. Electricity models are convenient regarding power consumption and the overall installation of the heater.

Electricity models with higher voltage input are required when multiple faucet connections are present. Some electrical models require upgrading the electrical architecture of the house before installing it due to high voltage requirements.

Fuel-Type

Temperature plays a vital role in the performance of the water heater. Temperature is heavily reliant on the proximity of the outlet points. If the outlet points are too many and are located at a considerable distance from the water heater, a notable drop in temperature is observed.

The hot water traversing through the pipes get colder when the distance is increased.So, water heaters equipped with higher temperature handling ability have to be considered when buying for a large household with multiple exit points.

Faster flow rates can also be held accountable for temperature drops too. If the water flows through the heater at high speed a drop in temperature is observed at the distant tap.

Microprocessing Technology

Microprocessing technology manages the overall functioning of the water heater. It manages the flow, heating mechanism and regulates the water output.

It is the core of an instant water heater and is vital to the heaters functioning. They have made the heaters smarter which require minimal input from the user and delivers hot water as long as required. 

Anti-Scale Devices

Anti-scale devices are incorporated into the heaters to remove dissolved hardness minerals by converting them into harmless, inactive microscopic crystal particles.

These crystals stay suspended in the water and are passed to drain. The filters require very little maintenance and remove impurities which could have an adverse effect on the working of the heater.

Digital Displays

Digital displays are useful for checking the state of the heater at any point in time. Digital displays are capable of displaying data related to the water’s temperature, flow rate, time of use etc. Digital displays are constructed out of LED and convey information to the user.

Flow Control

Flow control is used to manage the rate at which water flows in and out of the heater. The microprocessor processes the data sent by the flow sensor to supply power(electricity) to the heating element as per current flow rate. It helps to monitor the amount of water dispensed in a particular session.

Brass vs plastic drain valves

Brass valves are stronger than plastic ones. They do not break when in use and do not crack. Brass valves are immune to leakage and last longer. The heaters valve should be of brass. If not present, it can be easily replaced.

Condensing

Condensing refers to the process of extracting additional heat from the exhaust gases and supplying it to the heating unit. This passes out exhaust gases which are cooler and can easily pass through the vents without harming them. Condensing features minimises the cost of ventilation as PVC pipes can be used instead of the high-grade steel pipe which is costlier.

Energy Efficiency

Energy efficiency is the rate of consumption of electricity by the instant water heater during its operation. Newer models have gravitated more towards the idea of energy efficiency. Electricity rates have shot up from what they used to be, so the idea to perform more at less energy cost is appealing to the buyer as well. Instant water heaters are 25%-35% more efficient than storage tank heaters.

Warranty

Warranty is an important attribute to consider while buying a water heater. Warranty takes care of almost all inconveniences caused to the user when the product is not performing well. Warranty should include the heating element, coil, thermostat, tank etc. The warranty is mostly between 3-5 years depending on the product.

Installation and Maintenance

Installation and maintenance contribute to the longevity of the water heater’s life. Periodically scheduled maintenance can seem costly, but they will benefit you in the long run.

Proper installation should be carried out by trained professionals to ensure there are no loopholes in the system. Voltage requirements, safety standards, checking the flow rate are some points to keep in mind while installing the product.

Water Usage

Water heaters come in varying size and capacity. At a time, if you need to heat more quantity of water, then a product with a bigger capacity should be bought.

Space

During the time of installation, you should have a clear picture of the space to install it. Thus, buy a product according to the installation space only.

Safety

Most of the products come along with special features such as Auto-off so that the heater gets switched off automatically when the water becomes too hot. These small features which are concerned with the safety of the product and users must be considered.
