Tankless water heaters have grown in popularity, with households and businesses looking for ways to save money and be more environmentally friendly. However, myths about tankless water heaters persist.
This article will tackle some of those myths and the truth behind them.
TANKLESS IS AN UNPROVEN NEW TECHNOLOGY
This view is a common misconception. The truth is that tankless water heaters have been around for decades. They are now widely accepted and used in many residential and commercial buildings.
TANKLESS WATER HEATERS ARE EXPENSIVE TO OPERATE AND MAINTAIN
While tankless water heaters may have a steep upfront cost, they are more efficient than traditional heaters and save money on energy bills. They typically last longer than traditional tank water heaters, so there is no need to replace them as often.
Tankless water heaters require regular maintenance, but that still doesn’t make them more expensive than traditional tank heaters. Periodic maintenance can help extend the life of a tankless water heater, saving money long-term.
THEY HEAT WATER TO UNSAFE TEMPERATURES
Another common misconception is that tankless water heaters can heat water to unsafe temperatures. This is incorrect, though. Tankless water heaters use a thermostatic control valve to regulate the water temperature. It prevents the water from getting too hot. Also, tankless water heaters shut off if the temperature exceeds a certain level.
THEY DELIVER HOT WATER INSTANTLY
Tankless water heaters heat water quickly but not instantly. Instead, the water will take a few minutes to heat up, depending on the flow rate and the incoming water temperature.
THEY REQUIRE NATURAL GAS
While some tankless water heaters use natural gas, they come in electric and propane models. If natural gas is unavailable, households can still reap the benefits of a tankless heater.
THEY DON’T WORK WITH WELL WATER
This is also not necessarily true. Tankless water heaters can work with well water if the water is filtered and the minerals removed. Having an experienced professional install the tankless water heater is a good idea to ensure proper setup with well water.
VENTING IS TOO EXPENSIVE FOR TANKLESS UNITS
Venting for tankless water heaters isn’t always expensive or difficult to install. Many tankless water heaters come with easy-install venting kits. Some only require a vent pipe, so there’s no need for expensive ductwork.
LOW GAS PRESSURE MAKES INSTALLATION UNAFFORDABLE
Low gas pressure can make tankless heater installation pricier but not unaffordable. If the gas pressure is low, install an electric or propane tankless water heater. As another alternative, some tankless water heaters come with special valves that can reduce the installation cost.
