We were able to choose the best tankless water heater for the typical needs of an average person. But there are dozens of different models and sizes available, so in order to pick the best tankless hot water heating unit or system, you will need to keep in mind a few critical factors before finalizing your purchase.
Before you even pick a tankless water heater, it is quite essential to consider the following:
Below is our guide to tankless water heaters. We will briefly explain how a tankless water heater works, explain what you need to know before you purchase one, and let you in on the units' operating features so you're fully equipped to make an informed decision.
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. So make sure that your house's electricity system can manage the water heater you're going for.
Make sure that you have a circuit available that will handle the tankless water heater. Consult an authorized electrician to be sure that you know the specs of your house systems.
On the other side, if you decide to purchase a gas-fired water heater, there are a couple of gas types and venting requirements you need to consider, like your house's gas type - propane or natural gas.
Inspect your gas line to ensure it will satisfy the requirements of your brand-new gas-fired tankless water heater.
It's important that you choose a water heater with a flow rate that aligns well with the taps in your home. Each product has its own temperature limit and flow rate. If the water doesn't get hot enough, or if the flow rate is too low or too high, the heater won't do the job 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 will 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.
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. You should also be able to find a couple of tips online about what things you can do to make sure your heater withstands the wear and tear season after season.
Moreover, most manufacturers also provide a repair/maintenance warranty for their customers, just in case things end up going south. And more often than not, they do! So, make sure you've got all those ends secure.
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, you'll be running out of hot water all the time. The tankless system heats water as you need it, and this means you will have hot water on demand, wherever, whenever!
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 it. On the contrary, the tankless system only heats the water when you need it, making these compact gadgets more energy-efficient.
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. They come in both wall-mount and floor-mount options. So, they're very handy in that sense.
