While selecting to buy a tankless water heater you need to consider the following aspects:

  • Anticipated requirement and water usage GPM
  • Size of tankless heater required
  • Personal priority
  • Readily available source of energy in your locality (natural gas/electricity)
  • Installation cost
  • Comparison between the cost of both type of heaters
  • Location where you want to install the heater

Price comparison of electric vs gas

In terms of initial cost comparison between gas and electric heaters, it is the electric one that is more expensive since a whole house electric heater costs around $500 to $700. On the other hand, a full size gas powered heater can be bought within $1000.

Don’t just give up on tankless heaters due to high price. If you have bought after reading the tankless water heater reviews from a reputed brand then you will never regret your decision regardless of the type of heater because you will save much more on your utility bills. Very soon your heater will recover its cost and therefore, it is a safe and wise investment option.

Resource allocation:

It is a common assumption that gas is the cheapest form of energy and in a majority of appliances this judgment is correct. However, efficiency wise, gas powered heater is less efficient than the electric one. A gas tankless heater’s efficiency average is 85% whereas electric tankless heater’s average is 98%. Therefore, electric heaters are more efficient and their lifespan is generally longer.

Electric tankless water heater’s operating cost is also lower than gas powered heaters. Also, electric heaters get installed cheaply and this means people spend at least 15% more on gas heaters after buying. Another point to remember is that gas prices always fluctuate and therefore, the operating price of gas powered heaters may rise or fall. Conversely, electricity process seldom fluctuates and generally it stays stable. However, this estimate may vary according to your geographic location. There may be regions where natural gas supply is way cheaper and readily available than electricity. For such locations, gas tankless water heater would be a feasible choice.

The Installation Phenomenon:

Natural Gas: These are generally more complex to install and require more investment, care and caution. Before buying a gas powered heater you need to make sure the location where you will be installing because it will require ventilation space to fulfil air supply requirement for combustion. Do find out beforehand if your existing gas supply line and venting duct can be used or not because in many cases it cannot be used.

Electric: These present a rather favorable option because such heaters are generally 1/3 the size of a gas tankless heater and can be installed just about anywhere. Electric heaters do not require ventilating ducts and you can easily place it anywhere closer to where you are supposed to need hot water. This means, electric heater installation will be cheap and less complex. There is no particular requirement for air supply system or intricate ventilation in electric heater installation. However, you may need to inspect your existing electrical supply system before installing an electric tankless heater.

Maintaining:

In comparison with the gas powered tankless water heater, electric models require less maintenance. The only factor that needs to be checked in electric tankless heaters is its inlet filter which requires cleaning occasionally. Other than that, electric models are free of upkeep.

Conversely, gas models require thorough inspection every year that is conducted by a trained professional only for ensuring safe and reliable usage.

Water Usage proficiency

Since gas models of tankless water heaters usually are larger in size than electric ones therefore, these have bigger capacity and can easily fulfill higher demand of hot water. These heaters are best for large families and extensive business setting. Typically, an average family requires 4 to 8 gallons of water/min, which an electric tankless heater can easily fulfill.

What should Homeowners prioritize?

Lastly, the most important question.. what to prefer an electric or gas model?

This decision must involve considering a few factors such as the pros and cons of both kinds of heaters, evaluating purchasing cost and personal budget, installation expenses, operating costs, general maintenance requirements, efficiency and approximate water usage per day. Generally, electric tankless water heaters are perfect for small and medium-sized families. On the other hand, if you have a large family and larger capacity of water is required then a gas powered tankless water heater will be most suitable.

Either way, a tankless water heater is always a better choice than an energy-consuming tank model. So, make a long-term investment and play a defining role in eradicating environmental pollution.


How does a tankless water heater work?

To understand how they really work, you would first need to understand how a standard tank water heater works. In a traditional heater system, you basically have a large tank that holds and heats water. To get the hot water when you need it, the standard tank continually heats the water and keeps it at the desired temperature. This means that there is energy being consumed to keep the water hot even when it is not being used. This is known as standby heat loss.

On the other hand, a tankless water heater is not subject to standby heat loss because it heats the incoming water only when you need it, hence the term “on demand water heaters”. This is the main feature that makes them so energy efficient.

There are mainly two types of tankless water heaters: point of use and whole house heaters.

Point-of-use systems are compact in size and can fit in a closet or under your kitchen sink and they can heat enough water for one or two outlets. They are usually installed close to the outlet whether it is a shower or a kitchen sink. Installing them next to the outlet means there is no lag time for the hot water to reach your outlet. Lag time is the length of time it takes for the hot water to reach your outlet and this can sometimes be as long as several minutes. While this may not seem like an important issue, you need to bear in mind that you may be saving on your heating bill, but you may also be running up you water consumption.

The second type is the whole-house system. These are larger, more expensive to buy and can operate more than one outlet at a time without lag time. They are powerful enough to supply hot water to more than two outlets at a time without having the water temperature suffer as a result. They will provide you with a constant flow of hot water even if several outlets are being used simultaneously.

Finally, you also have the choice between electric, propane or natural gas models. The small point-of-use models are usually electric while the whole-house ones are powered by either propane or natural gas.

What size tankless water heater do I need?

Once you’ve figured out your flow rate and needed temperature rise, you will be able to make the correct choice. Gas and propane powered instant water heaters provide a lot more power and are mainly used for whole-house systems. If you have a family and need to run several water outlets at the same time then this is the choice for you.

If you are single or living in a household of two people, the electric model should suit you just fine. If you still want to ensure a hot water supply for several outlets in your home, you can install more than one electric tankless water heater at several outlets and you will have a more constant supply of hot water on demand.

Savings

Whether your old tank heater has broken down or you’re just thinking of switching to tankless, your main concern should be how much money will I be saving. A small comparison will show you that on demand water heaters cost more to buy and install but your return on investment is usually around 18 months.

However, you won’t be constantly heating up water in a tank since instant water heaters will give you the hot water you need instantaneously and only when you need it. This, in the long run, is where you will be saving a lot of money on your energy bills.

Another point to consider is the lifespan of a tankless water heater in comparison to a traditional one. While the traditional water heaters last up to 10 years, a tankless water heater can serve you for 20.

What are the advantages?

If you are thinking of switching to a tankless water heater, we have here the major benefits you will enjoy when you make that switch.

The first and foremost advantage is that on demand water heater never ever run out of hot water. This “on demand” feature is where all the other benefits fall in as well. Because they do not have standby heat loss as the traditional heaters do, tankless water heaters can cut down your water heating bill by around 20% as the hot water supply is instantaneous and doesn’t have to be heated up constantly to keep it at the desired temperature.

As far as installation is concerned, instant tank heaters are small and take up very little space in your home. Point-of-use tankless water heater can be installed near the outlet such as a kitchen cabinet and larger ones can even be placed on walls or even outdoors if you supply them with an anti-freeze kit. Most models come with a remote control so that you can operate them from a distance and they also have a panel where you can choose the settings that best suit you.

In terms of safety, the electric models do not emit greenhouse gases and switching to tankless water heaters means you never have to worry about your home flooding due to a ruptured tank.

Finally, and one of the major advantage of an instant water heater, they can last up to 10 years longer than the traditional tank water heaters.

There are also some disadvantages

Though the advantages well outweigh their disadvantages, it is only fair to point them out, for more information read the reviews.

Tankless water heaters cost up to 3 times as much as a standard tank water heater and installation and servicing are also a consideration. If you are choosing a gas model, you may need to upgrade your natural gas line to make it larger so that you will have a bigger supply. These units may also need expensive stainless steel tubing for installation and annual servicing. Electric models, on the other hand, may need an additional circuit.

If you are worried about the environment, you have to keep in mind that the gas-powered instant water heaters will produce greenhouse gases while the electric ones require energy to operate, but much less than a traditional tank water heater.

Finally, you will notice that your hot water output needs to be shared between all your household outlets but you need to keep that in mind when choosing your tankless water heater, that is why you have to pay attention to the flow rate when reading the reviews.
