Buying Guides

A home tankless water heater, also known as an on-demand or instant water heater, is a type of water heating system that heats water as it is needed, rather than continuously heating and storing water in a tank. This means that it does not have a storage tank, but instead uses a heat exchanger to heat the water as it flows through the unit.

One of the main advantages of a tankless water heater is that it can provide an endless supply of hot water, as long as the unit is properly sized to meet the hot water demand of the home. Additionally, they typically have a longer lifespan than traditional tank-style water heaters and can save on energy costs in the long run. They also take up less space, which makes them ideal for smaller homes or homes with limited space for a water heater.

However, they also have some limitations, such as they may not be able to provide enough hot water for multiple fixtures at once and they may have a higher initial cost. Also, it's important to consider the fuel source, whether it's electric or gas-powered, as it may affect the cost and installation process.

Overall, a home tankless water heater is a good option for those who want an endless supply of hot water and want to save on energy costs over time. It's important to consult with a professional to ensure that a tankless water heater is the right fit for your home and to ensure proper installation.

When choosing a tankless water heater for your home, there are several factors to consider:

  • Fuel source: Tankless water heaters can be powered by gas or electricity. Gas models are typically more efficient and have a higher flow rate, but they require venting and a gas line. Electric models are more convenient to install, but they may not be able to keep up with high demand.

  • Flow rate: The flow rate of a tankless water heater is measured in gallons per minute (GPM). Make sure to choose a unit with a flow rate that can keep up with your hot water needs.

  • Size: Tankless water heaters come in different sizes, so make sure to choose a unit that is appropriately sized for your home. Consider the number of bathrooms, residents, and the overall hot water usage in your home before making a decision.

  • Energy efficiency: Look for a unit with a high energy efficiency rating, such as the Energy Factor (EF) or the Thermal Efficiency (TE). These ratings will give you an idea of how much energy the unit uses to heat water.

  • Features: Some tankless water heaters come with additional features such as remote control, self-diagnostics, and freeze protection.

  • Brand reputation and warranty: Look for a unit from a reputable brand and choose one with a good warranty.

  • Professional installation is highly recommended for tankless water heaters, as it will ensure that the unit is installed correctly and that it will work effectively and efficiently.

It's also important to consult with a professional plumber or HVAC contractor to ensure that the tankless water heater you choose is compatible with your home and that it will meet your hot water needs. They can also help you determine the right size and flow rate for your home, and can provide guidance on the best options for your budget and energy needs.
