How Does a Tankless Water Heater Work?

Mention water heaters and most people think of the traditional tanked model, with the large white cylinder sitting in their basement. There is, however, another option: tankless water heaters, which get rid of the bulky tank and some of the problems that come with it. But how do they work and what separates them from traditional tanked models? And can they work in your Radnor, PA home?

Traditional models heat the water in the tank, then store it for use when you’re ready. Tankless heaters, on the other hand, use a gas heater or an electrical heater to warm up the cold water on demand. When you turn on the hot water faucet, the heater turns on and water passes through it, heating up very quickly. That makes the water heating process much more efficient, and makes it so the quantity of hot water you are able to use at one time is not limited by the size of your water tank.

The small size makes the units easy to place, and you can connect multiple tankless water heaters throughout your house to address you needs anywhere. They can be placed in out-of-the-way locations, usually near the faucet or appliance that they serve, and most of them require access to a gas or electrical power source to work.

In homes that don’t use a lot of hot water (41 gallons a day or less), they can save a significant amount of energy over tanked models: up to 34% according to the U.S. Department of Energy. They also don’t suffer from standby heat loss, since the water in a tankless model is not stored for any period of time. On the other hand, they cost more to install initially than tanked models, and they can’t handle the same volume of water with one unit.

That’s why it pays to discuss the prospect of installing a tankless water heater with the professionals at Carney Plumbing Heating & Cooling. We’re familiar with issues of sizing and fuel type, as well as any pertinent building codes which may affect Radnor, PA residents. We can determine the best option for you, then install the tankless heater with efficiency and care. Call us today to schedule any Radnor, PA tankless water heater service you need!
