What is a Tankless Water Heater?
A tankless water heater is a type of water heater that does not use a storage tank to hold hot water. Instead, it heats water on demand only when residents need it. This makes tankless water heaters more efficient than conventional water heaters, which lose heat as they stand by waiting for someone to need hot water. Like traditional water heaters, tankless water heaters come in two basic types: electric and gas.
Making the switch can be a big decision since upfront costs are typically higher than a conventional water heater, but tankless water heaters have better longevity and efficiency, which saves homeowners money. Here homeowners can find a larger discussion to help them decide if a tankless water heater installation is for them.
Signs it’s Time to Replace an Old Water Heater
The best time to consider tankless water heater installation is when the current water heater is on its last legs. Due to the cost of water heaters, there is no reason to make the switch before it is necessary. So, how do homeowners determine when their current water heater may need to be replaced? Look out for these signs:
- Old Age: Most traditional water heaters only last about a decade. After the tank hits the eight-year mark, it has likely lost efficiency and may be closer to needing repairs or a replacement than one would hope.
- Corrosion: When corrosion has occurred in the tank due to neglected maintenance or old age, it’s time to replace the water heater before the corrosion causes the water to be discolored or smell funny.
- Inadequate Hot Water Supply: Lost efficiency means less hot water. If the water heater forces everyone to take cold showers because the hot water runs out too fast or never gets hot enough, then it’s time to upgrade.
- Frequent Repairs: Except for some leaks and corrosion, professionals can repair most water heater problems. However, there is a time when it’s cheaper to install a new tank instead of frequently repairing the old one.
- Leaks: Most leaks in a water heater tank aren’t repairable and will only worsen. Consider upgrading as soon as leaks are noticed.
How a Tankless Water Heater Works
Tankless water heaters don’t have a large tank to store water in. In traditional water heaters, water is heated and stored while awaiting use. This wastes energy because it needs to be continually heated. Additionally, it means that hot water will run out as soon as the tank is empty.
Instead, tankless water heaters heat water quickly as soon as needed. With tankless water heaters, powerful burners or heating elements heat water as long as the flow is sensed in its piping, giving endless hot water for lower overall energy costs. Tankless water heaters also typically have a longer lifespan than traditional tank water heaters since they don’t have to constantly maintain a large volume of hot water, which can strain the system.
Benefits of Tankless Water Heaters
There are many reasons why more homeowners are starting to make the switch to tankless water heaters. Tankless water heaters spend more time sitting idle, which leads to a water heater that lasts longer and requires less service. Some of the other benefits of tankless water heaters are:
- Hot water on demand
- Endless hot water
- Lower energy costs
- Greater reliability
- Greater life expectancy of the unit
