How to choose the best tankless water heater in 2024?
To find the best tankless water heater for your home, there are few things to consider. Doing so will help you find the right appliance for your dwelling and avoid any that may be unsuitable.
- Location: The first thing to consider when looking for a water heater is where it will be installed. Tankless water heaters are either designed to supply an entire property with water or localized to a single use, such as a sink or shower. The former will require more power and be generally larger, so be sure to consider this before buying. What size is possible for your dwelling? The latter option may be more suitable for smaller properties.
- Water Flow Rate: As there is no tank to fill, a tankless water heater can sometimes struggle to supply hot water to multiple sources. Therefore it is important to consider the flow rate of water heated by the appliance. This is especially important to consider if living in a colder area, as a high demand of warmer water will be needed. Look for tankless water heaters with a flow rate of around 2 to 5 gallons per minute.
- Fuel Type: It is possible to buy either an electric or gas tankless water heater, so be sure to select one that is compatible in your home. Modern gas heaters are more energy efficient than gas appliances, but are usually more expensive to buy. However, gas water heaters may struggle to meet high water demands in cooler climates - especially if the water isn’t already preheated. So it is important to buy a heater that is suited to the water that is being used and the gas type that is available. An electric water heater is often a more suitable a gas appliance.
