Here's Why Your Tankless Water Heater Takes a While to Heat UpEven though tankless water heaters provide a wide array of benefits for your Northwest Arkansas area home, they do have a few downsides that can become a bit annoying. The biggest downside is the length it takes for the tankless heater to heat up the water. This will leave the homeowner searching for solutions to fix this annoying problem. Before you can address the problem, however, you must first understand why tankless water heaters take a while to heat up.

The reason why tankless water heaters take longer to heat up than traditional water heaters is because they are essentially a long, cold pipe. Traditional water heaters have a tank that is connected to a heating source – gas or electric – that keeps the water stored in the tank at a constant temperature. Tankless water heaters, however, do not have a storage tank that is continuously heated. Instead, a tankless heater has to push the water through the heater via the inlet and then through the outlet before the water is heated. This means you are starting with a cold heater and cold water. It typically takes an extra 10 to 15 seconds longer than that of a traditional water heater.

There are some things you can do to help decrease the wait time for the water to heat up. Something as simple as insulating the pipe with inexpensive and easy to install foam insulation that is designed for pipes. Another option that is a bit more extensive requires replacing the pipe with a smaller diameter or switching from metal to plastic. You can also reroute the piping so the total length of it is reduced. This, however, typically requires the help of a trusted plumbing and HVAC company.
