Save Energy & Money with a Tankless Water Heater 

Tankless water heaters allow you to enjoy all the hot water you need when you need it without excessive energy costs. When it comes time to upgrade to a new water heater, there are many advantages to ditching the tank for tankless water heaters in Stockton. 

A tankless water heater offers advantages for: 

  • Hot water on demand – The water heater only heats the water when you turn on a faucet or water-using appliance. This means you will always have hot water when you need it. 
  • Energy efficiency – Since energy isn’t wasted keeping water heated in a storage tank, tankless models offer greater energy efficiency. Tankless water heaters use about 30-50% less energy than a tank water heater. 
  • Compact size – There is no storage tank, which makes these water heaters better for places where space is limited. 
  • Longer lifespan – A tankless water heater can last up to 20 years. This is about twice as long as the typical tank water heater. 

When you decide to make the switch to a tankless water heater, you will need to choose the right model for your home. Although there is no storage tank, the size and capacity of the water heater are still important. You need to make sure that the water heater has the capacity needed to meet your family’s hot water demand. 

What is the Most Common Problem with Tankless Water Heaters?

The most common problem that arises with tankless water heaters is that they obtain mineral buildup overtime. Additionally, tankless water heaters parts eventually need replacement, similarly to traditional water heaters parts. Whatever the case, a local plumber can quickly assist with any water heater repair or replacement service to get your water heater running right.
