How Did We Pick the Best Tankless Water Heater?
We were able to choose the best tankless water heater for the typical hot water needs of an average person. There are dozens of different models and sizes available. In order to pick the best tankless hot water heating unit or system, keep in mind a few critical factors before finalizing your purchase.
What Should a Person Know Before They Purchase a Tankless Water Heater?
Before you even pick a tankless water heater, it is quite essential to consider the following:
The type of fuel that the water heater will utilize
The mounting position, size, and water flow rates each unit offers
The purpose for which the water heater will be used
Below is our guide to tankless water heaters. We’ll explain how a tankless water heater works, what you need to know before buying, and the units’ operating features. You’ll be fully equipped to make an informed decision.
What Are the Different Types of Tankless Water Heaters?
If you decide to stick with an electric tankless water heater, analyze the amperage, voltage, and circuit breaker requirements carefully before buying. Most of the devices will vary from 110V to 277V. Each model has different requirements for their electric element. Make sure that your house’s electricity system can manage the water heater and heating element you’re going for.
Make sure you have a circuit available that will handle the tankless water heater. Consult an authorized electrician to verify that you know the specs of your house systems. Doing so will optimize the usage of electric models and your particular electric tankless water heater model’s electric element.
On the other hand, if you decide to purchase a gas powered tankless heater, consider the gas types and venting requirements. If you’re going with gas units, first think about your house’s gas type – propane or natural gas.
Inspect your gas valve and line to ensure it will satisfy the requirements of a brand-new addition from a selection of gas tankless water heaters. In terms of combustion, gas tankless water heaters don’t rely on indoor air supply. However, you do still need to vent these types of hot water heaters.
How To Choose a Water Heater With the Right Flow Rate
It’s important to choose a water heater with a flow rate that aligns well with the taps in your home and your water usage. Each product has its own temperature rise limit and flow rate. If the water doesn’t get hot enough, or if flow rates are too low or too high, the heater won’t work properly.
For example, a shower might have a demand of 4 gallons per minute while a dishwasher may only demand 1.5 gallons per minute at 100 degrees.
By discovering the precise flow rate, you’ll be able to avoid any future problems. Also, it never hurts to discuss these matters with your plumber and have a second opinion, just in case.
How Do You Maintain a Tankless Water Heater?
Doing regular maintenance for your tankless water heater is a must if you care about its longevity. Ideally, you should bring about a maintenance session at least twice a year. Search for some tips online about what you can do to make sure your heater withstands the wear and tear. You want it to bring you hot water season after season.
Moreover, most manufacturers also provide a repair/maintenance warranty for their customers, just in case things go south. And more often than not, they do! So, make sure you’ve got all those ends secure.
What Are the Benefits of Tankless Water Heaters?
Endless hot water
A hot water system that utilizes a simple tank can only provide as much hot water as the tank can handle. And since your heater is only as good as your tank’s capacity, your whole house could run out of hot water all the time. The tankless system heats water as you need it. This means you will have hot water on demand, wherever, whenever! You shouldn’t have to push your hot water faucet past its maximum point.
Reduced energy bill fees
Even though tankless water heaters cost more than traditional tank heaters, they can save you cash on your utility bills. Tank heaters continually heat water, even if you are not using them. On the contrary, the tankless system only heats the water when you need it, boosting the energy efficiency of these compact gadgets.
While a regular tank system uses up a significant amount of space, the tankless system can fit in a corner of your bathroom or even beneath your kitchen sink. On demand water heaters come in both wall-mount and floor-mount options. So, they’re very handy in that sense.
