What Is a Tankless Water Heater?
Technology has positively touched the lives of people across the globe. Every year witnesses advancements in technology which thereby help in reducing the workload or burden on the shoulders of mankind. Researches and innovations are an ongoing process that does not halt midway. They yearn for more even after reaching a pitstop. A water heater is the best example. The basic concept behind a water heater is that of a machine that can provide hot water whenever necessary. But even after developing traditional tanked water heaters that can provide hot water, research and innovations didn’t stop there. They further went on in hope of better technology and came up with tankless water heaters.
A tankless water heater, as the name itself, suggests, is a water heating machine that does not need storage tanks. It does not store hot water for later usage. Instead, it is equipped with a heating unit, through which, cold water is passed and gets converted into hot water instantly. So, the users need not prepare or store water in advance for it to get heated. They can simply switch on the machine, and the cold water from a connected source will flow through it and come out as hot water. These heaters are also known as instantaneous water heaters and demand-type water heaters.
Tankless water heaters are sold like hot cakes in the market due to the multiple advantages that they can provide over a traditional storage-type water heater. If you are intending to buy a water heater, compare and contrast a tankless water heater and a traditional one to finally decide on which one is the best.
How Does Tankless Water Heater Work?
More than nine million water heaters are sold in the US alone and this wide popularity owes to the fact that they can offer a steady flow of hot water to the user. Tankless water heaters, devoid of any storage units, consist of many technologically advanced components that ensure a continuous flow of hot water. Some of the major components of a tankless water heater are gas supply, temperature sensors, water valve, electric board, flow sensor, gas valve, gas burner, ignition system, heat exchanger, vent, exhaust, etc. It is the combined effort of these elements that ensure the efficiency of a tankless water heater. Let’s have a look at some of the key components of a tankless water heater in detail:
The ignition system of tankless water heaters differs in various models. But generally, electrodes are used to ignite the fuel and initiate the heating process. Some models contain more than one electrode to provide ignition. There is a part called a gas burner in the water heater system, and it is at this part that the fuel is ignited.
The gas burner is the part at which the ignition process happens and the flame is maintained steadily for a flawless water flow. Gas burners are usually made of stainless steel to gain maximum heat output. The burner can have one or more flames, but the flame should be maintained in a blue color, which is the sign of a steady fuel supply and proper combustion. The user can monitor the flame of the gas burner through a window-like opening provided in the front of the heater. The user is expected to observe and control the flame accordingly to avoid any dirty flames or improper combustion.
A heat exchanger is a part that situates right above the gas burner and the ignition system. It is usually made of copper or stainless steel, which are excellent heat absorbers. It receives the heat from below and transfers it to the concerned water flow, making it hot. It is constructed in a tube or cylinder shape enabling water to pass through it. Heat is applied to the water from all sides of the tube making them instantly hot. Heat exchangers tend to get wear and tear after ten to twelve years and the biggest advantage of it is that it is replaceable.
The combustion system of a tankless water heater consists majorly of two elements: gas valves and a combustion fan. Gas valves are the modulators of the flame produced. There are on and off modulators that should be used as per the discretion of the user. A combustion fan spins in the direction of the flame to ensure the mixing up of air with the flame for better burning.
Flame sensor and Overheat sensor
Flame sensors and overheat sensors are two major safety features of a tankless water heater. Flame sensors monitor the status of the flame once it is burned. It makes sure that the flame is burning at a reasonable rate and in case the flame seems to be absent even after the ignition, it informs the gas supply to stop the supply and shut down the water heater. The overheat sensor looks for any temperature fluctuations in the system. It makes sure that the system shuts down if a higher than normal temperature is identified. This component will only allow the system to further start only after it is cooled properly.
The power panel or the control panel of a tankless water heater provides enough information for the smooth running of the machine. Information like fuel status, flame strength, etc. are shown on an LCD at the top of the water heater, named power panel. In case any anomalies happen within the system, the necessary error codes will also be shown on the panel.
A tankless water heater is equipped with numerous safety features. Some of them are the fan speed monitor, frost sensor, water flow sensor, pressure relief valve, etc. All these enable proper safety for the machinery.
What Are the Benefits of Tankless Water Heater?
Tankless water heaters had taken the markets over by storm within years of starting the sale. They nearly immediately replaced the traditional tanked water heaters and have emerged as the top sellers in the section. People opt for tankless water heaters for the numerous advantages that they offer. Some of the popular positives of tankless water heaters are as follows:
1. Saves Energy
Traditional water heaters tend to consume comparatively a lot of energy as they have to be prepared for hot water, way before the actual usage, and thus spend energy on keeping a particular amount of water hot all the time. But when it comes to tankless water heaters, they need not store water in advance for heating purposes. They are connected to any cold-water source and when switched on, the water flows in from the source and gets converted into hot water immediately. So, the consumption of electricity is extremely low when compared to the traditional water heater. It is estimated that tankless water heaters only use 25%- 30% less energy than their traditional counterpart.
2. A steady flow of water
When it comes to a traditional water heater, it requires a little bit of time to heat a particular amount of water and once it runs out of that water, it will have to leave the machine on for some more time for another set of water to get heated up. But things are extremely convenient with the tankless water heaters because they are connected to a water source and they consist of a heating unit that can heat how much ever water flows through it. So, the water flow will be steadier and more continuous in the tankless water heaters.
Tankless water heaters come with no tanks, unlike the traditional water heaters that are attached to big tanks. This absence of extra tanks and accessories makes the tankless water heaters a space-saving option. They are quite small and thus, can be mounted on the wall for saving further space.
4. High life span
Traditional water heaters tend to go bad after several years. But tankless water heaters are estimated to have a life span of twenty to twenty-five years minimum. Its components are replaceable and this makes the lifespan even longer. If maintained properly, a tankless water heater can last for decades intact.
5. Less maintenance required
One of the most important advantages of a tankless water heater is the fact that it need not be maintained as frequently as the traditional ones. The traditional water heaters demand to be serviced annually or sometimes every six months. But when it comes to a tankless water heater, it need not have annual maintenance and it is observed that it can function perfectly for up to five years without any maintenance.
6. Availability of options
Tankless water heaters are available in multiple models and versions. They are available in various fuel-compatible versions that can be chosen according to the priority and preference of the customer. There are both electric and gas models available both of which have their fair share of pros and cons.
How to Choose a Tankless Water Heater?
Choosing a tankless water heater should be done with ample care and attention. There are many models available in the market that have different features and specifications. So, if the product that you buy has to fit into your household perfectly, you have to put in much effort and time in understanding what exactly are you looking for in a water heater. Be well versed with your needs and budget, so that you don’t stray off your ideal water heater.
The following are several features that you should be looking for in a water heater before purchasing:
The size of a water heater is the major criterion that has to be considered primarily before purchasing one. Monitor the hot water needs of your household and calculate the approximate size of a water heater required. There is no point in buying water heaters that are bigger if your water needs are meager. It could only lead to space consumption and unwanted energy utilization. So, make sure that you are buying the right-sized water heater for saving space, energy, and money.
It is important to calculate the energy efficiency of a water heater before buying it. Energy efficiency simply means the amount of fuel consumed by the water heater to produce a unit amount of hot water. It is always better to have a heater of high energy efficiency.
3. Type of fuel used
Tankless water heaters are available in numerous versions of various fuel types. There are gas-powered heaters, electric heaters, and solar-powered heaters and the choice is of the customer. Each fuel has its positives and negatives and enough thought should be given to this criterion before purchasing a tankless gas heater.
4. Price range
Tankless water heaters are available in a wide price range. The price of the heater depends upon the size of the heater, fuel used, brand, etc. So, with careful curation, you can find the best deal out of the lot. While settling on a price, check whether it includes the installation cost. Because installation cost does cost a decent sum of money and it should be confirmed with the seller before buying a product.
You should be very clear about the purpose of the water heater as to whether it is for the indoors or outdoors. If it is for an outdoor purpose, make sure you ask for heater models with temperature-regulating mechanisms. There are water heaters that come with self-warming elements that are capable of withstanding the harsh conditions of the outdoor.
6. Warranty coverage
Unlike many other devices that come with a single product warranty, a tankless water heater could or could not come with a single product warranty. Generally, manufacturers provide a separate warranty for the various parts of the water heater. For example, the heat exchanger part of the water heater is usually provided a warranty of up to 20 years whereas the other parts have only coverage of up to 5 years. So, it is extremely important to compare the warranty coverage of various models to find the best deal for you.
Tankless Water Heater FAQs
What size tankless water heater do I need?
Deciding on the size of the tankless water heater should be according to the user’s discretion and needs. The amount of hot water that you might need at a time should be rightly calculated to find the most appropriate water heater. This rate of water that has to be flown through a water heater in a unit of time is called the flow rate. Once you have determined the flow rate of the required devices in your household or wherever you plan to plant the heater, calculate the temperature up to which it should be raised when running. For example, a regular-sized shower head would need approximately 3 gallons per minute at a temperature of 104 degrees Fahrenheit. In this way, the requirements of each of the devices should be calculated and the net needs should be calculated, and then search for an appropriately sized one. If the requirements are high, you’ll have to opt for an accordingly bigger-sized water heater.
How to install a tankless water heater?
There are different kinds of tankless water heaters available. For reference sake, let’s look at how a tankless gas water heater is installed. Before proceeding to install a water heater inside your household, make sure there are no guidelines regarding such activities in your local authority. Make sure such legal aspects are taken care of. For installing a gas water heater, find an appropriate spot where air circulation is possible well. The vent of a tankless water heater usually opens directly to the outside and thus, there should be an open space through which the vented heat and air can go out.
Once you are final with the spot, take the accurate measurements of the water heater and build a frame or holder on which the heater can be mounted. Ensure the strength and sturdiness of the holder to avoid any accidents. Then connect the home gas line to the water heater unit using a tee. Add further components like gas regulating valve and sediment trap at this point. At the top of the heater, some valves have to be connected to the water supply line; check them well and connect them appropriately. The water heater must have come with a pressure relief valve; refer to the instruction manual and connect the valve accordingly. Double-check every component for any kind of leaks. The exhaust vent and associated apparatus should also be connected afterward. Then verify that the connections are intact and working by switching on the system and conducting a trial.
How to flush a tankless water heater?
Flushing a tankless water heater is extremely important whether it is gas or electric. Over regular usage, the water heater gets deposited with sediments and the process of removing this accumulated sediment is called flushing. It is ideal to flush the water heater on an annual basis. First of all, make sure that the water heater is switched off and is completely devoid of any power. Close the valve that permits water to flow into the heater so that no water will enter the heater during flushing. Also, open the pressure relief valve to ease out the pressure inside the system before flushing. Place the pump that is used for flushing inside a container or a bucket and then connect its hoses to the cold-water port of the heater. The port through which hot water comes out of the heater should be left open and loose into a bucket or container. Pour the flushing or cleaning liquid of your choice into the pump and switch it on. The liquid will pass through the system and comes out along with the sediments through the hot water port. Repeat the process as necessary and once finished, switch off the pump, flush out the excess liquid from the heater using freshwater, and then clean the filter inserted into both cold and hot water ports separately. Put the filters in their designated place, open the valves that were closed before, and then switch on the heater to make sure that everything is intact and is working perfectly.
How long does a tankless water heater last?
The lifespan of a tankless water heater is much better than a traditional water heater. If provided with proper maintenance, tankless water heaters are estimated to last for almost 20 years. Some of the newest additions to water heaters use advanced technologies and are offering more than 20 years as an estimated life span. This longer life span owes to several key features of tankless water heaters. Unlike the traditional water heaters, tankless ones have replaceable parts. In case any kind of issue happens with any of the parts, they can be replaced and the entire system functions perfectly afterward. Also, they are not quite vulnerable to corrosion as they are not constantly exposed to water and moisture like the traditional water heaters. They come in close contact with water only when they are being operated, unlike the traditional ones that store water all the time. If you take care of the tankless water heater well and make sure that they don’t get affected by corrosion of any kind and provide necessary servicing, they are bound to last decades in perfect condition.
How to clean a tankless water heater?
A tankless water heater needs to be cleaned regularly to avoid any kind of sedimentation. The process of removing the sediments and dirt particles from a tankless water heater is called flushing. It has to be done annually for a standard-sized water heater. It is done with the help of a pump and in most cases, professional help would be ideal to do that process properly. Along with flushing, several other things have to be done to maintain cleanliness in a water heater. The first one is to clean the air filter of the water heater. You can simply switch off the heater and remove the air filter from the front part of it. You can wash it using water and soap and let it dry for half an hour before placing it back. Doing this occasionally can keep the system clean.
Tankless water heaters consist of removable parts. So, make it a habit to remove the necessary parts and clean them separately. You can check for any kind of clogs in the machinery and clean it accordingly. Use an appropriate cleaning agent to prevent any kind of reaction. Adding an extra filter is also recommendable to keep the water heater clean.
How to turn up a tankless water heater?
Adjusting the temperature of a water heater is usually an uncomplicated process. It does depend on the kind of water heater that you are using. But still, for most water heaters, the power panel contains information regarding the level of temperature within the system at present. It could either be a digital input method or a manual one. The dial or the switch provided for this is connected to the gas control valve and when you raise or reduce the temperature, it is actually the inflow of the gas that is regulated, and the flame is thereby controlled and creates the desired temperature. But what is to be noted is that the temperature does not change right away once you have provided the input. It would at least take a couple of hours to have the desired impact. So, make sure to wait it out before any conclusion. Also, while turning the heat up, make sure to limit it to 120 degrees Fahrenheit, as any temperature above that could possibly harm you.
Why is tankless water heater not getting hot?
A tankless water heater might not function properly due to several reasons. As it contains multiple components, chances are high for any of them to go wrong at any time. First of all, check whether the required valves are open or not. If any of the valves are not open, ignition won’t happen, and thus, the temperature would not go up. Also, make sure that the pressure condition inside the system is ideal for ignition and combustion. If any anomalies regarding pressure are noted, try to adjust it accordingly with the pressure gauge in the power panel. Check whether the water heater is properly cleaned. If the system is unclean and contains any sediment deposition, it could clog it and resist it from functioning smoothly. Also, if you are staying in a cold weathered area, check for frosts inside the water heater; it could also hinder the proper working of the water heater.
