Hot water on demand; this is what makes tankless hot water heaters so popular and highly in demand. Unlike ordinary water boiler which are inefficient, consume lots of power and have limited hot water storage capacity these heaters are more than efficient! They give you a steady supply of hot water throughout the day without consuming that much of power.
This is because tankless heaters heat water only when you need and want it to instead of wasting electricity storing heated water. It’s no wonder so many people are now turning to, and using tankless water heaters for their showering needs.

Factors To Look Out While Buying Tankless Water Heaters
Check the water temperature
Setting the required water temperature in the waterheater is an individual choice. However if you want to maximize your power savings, it’s better if you maintain a lower water temperature.
Then again, too low water temperatures can result in pathogens like Legionella surviving and reaching your water. As all heating boilers, conventional or tankless have to heat water from the original input point, you need to find out what the incoming temperature of the water is in your area before you buy your system. This is because lower temperatures need more energy to heat water to the required degree.
Electric or Gas tankless water heater
The conventional heating boilers work either by igniting natural gas or propane or using a fully electric system. It’s easy and better replacing a gas or propane system with a propane powered or tankless gas waterheater.
It’s also possible to replace the old gas system with an electric heater; but you’ll have to expand the replacement system’s electrical input as the electric heaters require more direct electrical current to work.
However replacing a conventional electric heating system with a gas tankless boiler is a complex procedure as you not only have to install gas lines, but also install ventilation systems for the excess heat the systems produce. So it’s not something you can do on your own, but which requires an expert’s help.
As tankless water boilers provide continuous hot water, you need to decide what size tankless heating boiler do I need based on its flow and not its capacity. This is because while these heaters never run out of hot water like storage waterheater, they cannot heat water fast enough to serve numerous fixtures at a time.
Tankless water boiler receive BTU (British thermal unit) input and efficiency ratings which determine the heater’s flow rate. A BTU is the amount of energy used to raise a pound of water’s temperature by 1F where higher BTU ratings indicate a higher flow rate.
Gallons per minute or (GPM) determines the heater’s flow rate or the amount of hot water it produces where the cheaper systems have a low GPM of about 1.2 to 6 gallons per minute. While a heater which provides hot water to a single bathroom sink is rated 1.2GPM, 2.6GPM tankless waterheater can handle one shower at a time. A 4GPM model can handle a shower and a sink while a 6GPM heater, 2 showers.
Generally, the water pressure drops off and the water boiler’s temperature falls once the gpm of the heater is reached. This is because these heaters are tankless and so only heat water at input using copper housings and can heat fixtures based on its GPM.
It’s thus better to buy the more expensive systems which max out at 9 gallons per minute or more if you have a large house and family with many fixtures needing hot water. You’ll end up disappointed replacing your conventional heaters with a smaller system.
Tankless heating boilers electronically measure the water flow which automatically turns on the heater. Higher flow requirements mean slower hot water. The initial flow activation is under a gallon per minute, between 0.3 and 0.9 gpm for most heaters. Lower gpm means faster hot water. The water flow is managed and detected by advanced microprocessors in the new hot water boilers.
It’s important that tankless heating boilers be fitted within about 50feet of a power source. This should not be a problem as they can be easily mounted on interior or exterior walls.
Besides this, there are many benefits associated to installing these heaters at home and between tank vs. tankless.
Hot water at your comfort and convenience
Tankless water heaters are considered the epitome of comfort and convenience as you just have to push a button to get a continuous supply of hot water. There’s no more scheduling of bathing times for the family or risk of sudden temperature fluctuations due to revolutionary technology and design.
Unlike traditional tanks where available hot water diminishes at one time so that people end up postponing their shower so that more water is heated, tankless heating boilers have sufficient water for everyone. Moreover, these heaters are compact in design, and can be mounted on walls or in corners, and not necessarily need large space like the traditional heaters.
Tough and durable
As tankless devices have an all metallic framework and heavy duty construction, they are a tougher and more durable option to conventional heaters. They are also long-lasting and once installed, you needn’t worry about them for at least 20 years, double the expected lifetime of ordinary heaters.
So investing in tankless water heaters, even if its a portable one is a plus point while building a new home or while upgrading a house to live in for a long time. Moreover, the presence of a tankless heating boiler proves beneficial, and a strong selling point to homeowners planning to sell their house.
Uses less power
These devices run mainly on gas or electricity, which reduces power consumption a lot. So though the gas versions are faster and more efficient than its electric counterparts, tankless waterheater are on the whole more power efficient and time saving than conventional heating boilers. And as water is heated on demand, not much energy is lost or wasted due to standby heat loss.
Tankless water heaters have many built-in heat settings and controls which offer greater flexibility for easy regulation of the quantity and temperature of water. Moreover, its compact size means that these heaters are not confined for use only in bathrooms. They can also be installed outdoors to boost the cleaning results of appliances like dishwashers and washing machines.
Saves energy and is then environmentally friendly
As tankless heating boilers save up to 27 -50% of energy because of its power saving and ergonomic design, these heaters are environmentally friendly. Moreover, you are assured of fresh and clean water throughout the day as dirt or other impurities in the heater do not accumulate in it.
Safe to use
These waterheater are safe to use as there’s no risk of any short circuits or gas explosions as they run on a full proof and secure power supply system. Moreover, its insulation covering prevents accidents and its plastic covering protects from any external damages and depreciation. They are especially safe with kids around as its smart sensors cut off the power supply when the machine’s not in use and there’s no risk of spillage with its tankless design.
Tankless heating boilers generally come with a longer warranty, of about 15 years when compared to the 6 years warranty of traditional boilers. There’s also no worry of water spilling on the floor due to the breakdown of the heater.
Though you may have to initially spend more on the cost of tankless heating boiler, you end up saving money in the long run. Unlike traditional heaters which heat and store hot water, only a small amount of water is heated as and when required in waterheater without tanks.
Uses less space
Traditional deices may hold between 40-60 gallons of water and measure 5 feet tall, to thus take up lots of space. However tankless water heaters are only 20-28 inches in size and are thus more compact to be installed in more areas to give more space for other things.
Choosing Between Gas And Electric
Choosing between these two can be easy for people who base their decision based on the power availability at home. It’s when your household can accommodate both types of heating boilers that you have to decide based on other factors. There is no ‘better’ heater between the two; you have to decide based on factors like your household circumstances, how much is a tankless waterheater and your hot water needs and preferences.
The rates of these tankless heating boilers differ drastically where the tankless electric water heaters are cheaper than the gas-powered counterparts. While good quality electric tankless waterheater are available for as cheap as $500, you need to spend as much as $1000 for reputed gas heaters. Moreover, gas heating systems with electronic ignition systems and other additional features cost even more.
Gas heaters are not only expensive to buy, it comes with a higher installation cost. On the contrary, electric units are easier, and thus cheaper to install as they are small and less complex to install.
They fit practically anywhere in the household like under the sink or in closets. However the gas versions are difficult to install as they require ventilation, gas supply and other things which normal houses may not have. This is why you first need to find out if your present venting ducts and gas supply lines can be used, which unfortunately can’t.
- Operating costs
Despite its initial costs, gas water heating systems are cheaper to operate than their electric counterparts. This is the main reason for consumers buying them; with the hope of recovering the investment money through reduced operating costs.
However if your locality has limited natural gas supply, it’s operating costs will increase. Moreover, while electricity rates are expected to remain stable, it’s not the same with natural gas, which may increase in the future.
- Water supply
Gas and electric heaters supply different levels of hot water. While the electric versions can provide as much as 8 gpm, sufficient for the average family, the gas versions can provide a larger supply of hot water. They are thus a better option for homes and buildings needing lots of hot water.
While gas heater have to be inspected annually by licensed technicians for its safe and efficient use, electric tankless hot waterheater need no maintenance. At the most, they require some occasional cleaning of the inlet screen filter.
So there’s no ‘better’ tankless water boiler between the two. You need to weigh the pros and cons of both these types of heating boilers before choosing the right one for yourself. You need to consider its installation and tankless hot water heater cost, maintenance costs and of course, how much hot water you and your household require.
However whichever choice you make, tankless water heaters are definitely better than the energy sucking conventional water heaters. They not only save you money, but also reduce the amount of carbon emissions to the environment.
How Does It Work?
As you know, water heater tankless do not heat and hold water in a tank. They basically heat the water by circulating it through a series of electric coils or burners and then pass the hot water through to the faucet or appliance.
These heaters never run out of hot water unless the demand for water at one end surpasses the unit’s heating capacity. This means while a tankless unit may handle the flow of 2 people taking showers at a time, they may end up in a cool shower if the dishwasher or washing machine is started.
While storage heating boilers deliver water at a set temperature, the temperature of most tankless units depends on the flow and temperature of incoming water. This varies greatly from one area or season to another. The unit’s capacity is thus measured by the number of degrees its temperature increases at a given flow which is expressed as gallons per minute.
It is because of this required response time and heat output that most whole house tankless water heater units are gas-fired and the smaller, single-fixture unit storing a few gallons of water are usual electric versions.
The gas-fired tankless heating boilers need venting with flues generally larger than those found in conventional gas water heaters. Some units also have power vents wherein gases can be exhausted out through a side wall and are best used for replacing electric water heater where it’s expensive venting out of the roof.
Heat Pump Water Heater Vs Tankless Water Heater
You've probably heard of tankless water heaters, which heat water on demand rather than storing it in a tank. But what about a heat pump water heater? While both types of water heaters have their pros and cons, you may be wondering which one is right for your home.
Heat pump water heaters use electricity to move heat from one place to another. In the summer, they can be used to cool your home. In the winter, they can be used to heat your home. But in both cases, they can also be used to heat water. Tankless water heaters, on the other hand, use gas or electricity to heat water on demand. So, if you have a high demand for hot water, a tankless water heater might be the better option. But if you're looking to save on your energy bills, a heat pump water heater can be a good choice. Here are some things to consider when deciding between a heat pump water heater and a tankless water heater:
Cost: Heat pump water heaters can be more expensive to purchase than tankless water heaters. But they can also save you money on your energy bills.-Installation: Heat pump water heaters must be installed by a professional. Tankless water heaters can be installed by a do-it-yourselfer.
But if you're not confident in your ability to install a tankless water heater, it's best to hire a professional.-Size: Heat pump water heaters are typically larger than tankless water heaters. So, if space is limited in your home, a tankless water heater might be the better option.
Maintenance: Heat pump water heaters require less maintenance than tankless water heaters. But both types of water heaters should be cleaned and flushed regularly to prevent buildup and keep them running efficiently.
If you're still not sure which type of water heater is right for your home, contact a professional to discuss your options. They can help you choose the best option for your needs and budget.
Do tankless water heaters require maintenance?
Depending on the temperature you've set for the heater, you'll need at least once or twice a year of service to the heater. For high temperatures settings, you need to service the unit after every six months. This keeps it durable and able to serve you for a long time.
How much time do I need to get the water hot from the heater?
The heat is fast and will heat the water in 15 seconds. This doesn't guarantee you water in your faucet at that time, but you'll wait until the same time you get it from the tank systems. Note that different heaters will still work differently to get you hot water in a varying amount of time.
Do I need to flash out my tankless heater?
Yes, you'll need to flash out the tankless water system because mineral deposits clog the system if not handled well. Additionally, the clogged system might lead to overheating your water heater, which will affect the entire system.
What size of tankless water heater do I need?
The number of users determines the size. If you have a family of five, a good unit is a 10 GPM gas tankless heater or a model with a 27 kW electric tankless heater to ensure you enjoy the entire heating period without lacking hot water.
Vested with all this information, it’s thus easier choosing the right device for your home’s hot water needs. You basically have to choose your heating boiler based on its heating capacity, water temperature and if you want a gas or electric unit.
As both have their share of pros and cons, you may find these tankless waterheater reviews with their features, helpful at choosing the best tankless heating boiler. The more tankless hot water heater reviews you go through, the more informed you are at choosing the best waterheater.
