New Year, New Water Heater: Should You Consider a Tankless Water Heater?
A hot shower that doesn’t last as long as it used to or rumbling sounds coming from the water heater are a couple of signs that tell you ought to replace your water heater. While you can always buy another traditional water heater, whippleplumbing.com says that you may consider using a tankless water heater. Before you go and purchase a tankless unit, here are information that may help you consider if this water heater is right for your home.
How Tankless Water Heaters Work
Unlike traditional water heaters that store hot water and are ready for use at all times, tankless water heaters do not store hot water. They only heat water on demand. After turning on the hot water tap, cold water flows through the pipe into the unit. The flow sensor then turns on a heating element to heat the water to the preferred temperature. Turning off the hot water tap will cause the flow sensor to switch off the burner.
How Tankless Water Heaters Are Powered
You can use gas (propane or natural) or electricity to fuel tankless water heaters. With standard tank heaters, gas-powered units require venting. On the other hand, venting is not required for tankless units. Just make sure to adhere to the minimum voltage and AMP requirements.
The Various Types of Tankless Water Heaters
Whole house and point of use are typically the two types of heaters you can choose. Whole house heaters are powerful enough to heat water for an entire household. Conversely, the point-of-use heaters have a low flow rate that can only accommodate a single appliance or location. For this heater, you need to install it next to where it’s needed, such as under a sink.
Take note of the above information in case you’d like to switch to a tankless water heater. While switching to a tankless water heater may have a high initial cost ($2800 to $4500, depending on the brand), it does pay for itself in the long run. A tankless water heater can last for more than two decades, almost double that of a traditional water heater’s life.
