Does Your Tankless Water Heater Take Too Long to Heat Up?

Tankless water heaters are a great choice, especially if you don’t want to run out of hot water due to a limited tank size. But you can face other potential problems – like having a long wait before you actually have hot water after turning on the faucet. When this happens, it’s time to schedule tankless water heater service in Salt Lake City.

The problem may not be one that really requires “fixing” because nothing is technically wrong with your tankless water heater. But we can assess the situation, get down to the source of the problem, and offer solutions to help. Keep reading to learn more about why it may take a while to get hot water when you first turn on a faucet as well as what we can do to fix the issue.

Size and Capacity Considerations

You may think that tankless water heaters are a one-size-fits-all solution, but this is not entirely true. Tankless water heaters come in different sizes just like tank water heaters do. Depending on the size of your family and your water usage expectations, you may want to install a larger tankless water heater or more than one system.

A large demand on your tankless water heater at one time can exceed its capacity. For example, your tankless water heater will only be able to heat so much water at any given time. You may have to strategize and spread hot water tasks out over the course of the day, instead of using hot water at multiple sources at the same time. Taking a shower in one room while the washing machine runs on a hot cycle may be too much for your tankless water heater at one time.

Distance from Tap

When it comes to water taking too long to heat up, this is usually an issue with the tankless water heater being farther away from the tap where you are located. Water appliances, sinks, and bathtubs that are closer to the tankless water heater will receive hot water more quickly.

If your tankless water heater is on one side of your house, and you have bathrooms and water appliances on the opposite side, faucets could take longer to produce hot water. This is because the water has to travel a greater distance across your home.

Additional Options

If you’re experiencing issues with your tankless water heater not heating up fast enough or having low water pressure due to demand, you do have some options. Technically, nothing is wrong with your tankless water heater; it is just too small or too far away to meet your needs and expectations. 

We have many homeowners who elect to install a second tankless water heater on the opposite side of the house. The solution usually solves both problems. With a tankless water heater that is closer to your water sources, water will heat up more quickly. Since you have double the capacity, you’ll also be able to use hot water at more than one place at a time without a negative impact on water pressure.
