Things to Consider When Buying a Tankless Water Heater

  • Anticipated requirement and water usage
  • 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: 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.

Installation Considerations

  • 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.

Maintenance

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 Efficiency

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.

What are the Advantages of a Tankless Water Heater?
