Buying Guide
When looking for the best tankless water heater, there are a few key features to consider. We’ve used and tested various models, and here are some factors to keep in mind:
Fuel Type
One of the first things to consider is the type of fuel the water heater uses. Tankless water heaters can be powered by natural gas, propane, or electricity. Natural gas and propane models tend to be more energy-efficient, but they require a gas line to be installed. Electric models are easier to install, but they may not be as energy-efficient.
Flow Rate
Another important factor to consider is the flow rate of the water heater. The flow rate determines how much hot water the heater can produce at once. If you have a large family or use a lot of hot water at once, you’ll want a water heater with a high flow rate.
Temperature Range
The temperature range of the water heater is also important to consider. Some models have a limited temperature range, while others can be adjusted to a wider range. Make sure the water heater you choose can provide the temperature range you need.
Installation
Finally, consider the installation process for the water heater. Some models require professional installation, while others can be installed by the homeowner. Make sure you choose a water heater that you feel comfortable installing yourself, or that you can afford to hire a professional to install.
By considering these factors, you can choose the best tankless water heater for your home that meets your needs and budget.
