Four Tips to Help You Choose a Tankless Water Heater


Many of you may be considering buying a tankless water heater for your home. And while you can choose from a multitude of high-quality water heaters from Mainline Heating & Air, you may not know where to begin when it comes to choosing a water heater. To help you out, we thought it would be useful to prepare a brief article discussing this topic. If this is something that you want to learn more about, read on for four tips that will help you choose a tankless water heater for your home.

Pay Attention to the Warranties

While it may not be directly linked to how your water heater performs, you’ll want to pay extra attention to the warranties it comes with. Good quality heaters will come with an extended warranty that will have you covered in the case they break down. In the case that you’re choosing between two seemingly equal water heaters, the warranty they come with may just help you decide on which heater to get for your home.

Check the Water Heater Efficiency

When it comes to performance, there are very few things that are more important than water heater efficiency. Water heater efficiency is what will dictate how well the water heater can heat water as compared to other water heaters out on the market. While this may seem complicated, you’ll be glad to know that most heaters make use of an energy rating called Energy Factor (EF). You can use EF to compare heaters to see which one is the best when it comes to efficiency. The higher the EF rating, the more efficient the device will be.

Determine the Right Size That You Need for Your Home

You’ll need to determine the right size of a tankless water heater for your home. This can be rather tricky as the “right” size will depend on your specific situation. A good rule of thumb to follow would be to get a larger water heater if you have several people using hot water in your home.

Consider the Power Source

Lastly, you’ll want to consider the power source of the tankless water heater. When it comes to power sources, the most common types are propane and electric. Now, neither of these power sources are better than the others as they all come with unique advantages that can make them a good choice for your home.

Electric power tankless water heaters may be the most convenient. However, you have to be wary if your home is on the older side. Older homes come with weaker electric systems. This can cause problems as adding a water heater could potentially overload your system.

Propane heaters are usually more powerful than electric heaters. They’ll also allow you to save on your home’s electricity bill. The main downside to propane water heaters is they take a while to heat up. So much so that homeowners usually report inconsistent water temperatures when using propane tankless water heaters.


We hope these tips help you choose the best tankless water heater for your home. While it may seem like a lot of work to have to go through the different aspects of a water heater, taking the time to be thorough about your choice of water heater will prove to be beneficial for you and your home in the long run. Be sure to keep all of these tips in mind so that you can make the most informed decision about your choice of a tankless water heater.
