Tankless Water Heaters

If you are the last one in your family to have a shower and find it turning cold before the shampoo is washed out of your hair…you may see tankless water heaters as the answer.

How They Work:

Tankless water heaters are gaining in popularity. These high-power water heaters instantly heat water as it flows through the device and do not retain any water internally except for what is in the heat exchanger coil. Tankless water heaters are very small units, typically hung on the side of a house, which are preset to a specific temperature. When you turn on your hot faucet, a device in this unit is activated by the flow of water, triggering it to be heated instantly. Therefore, your water is only heated when you are using it. You never have to pay for “standby” water like traditional water heaters which have to store the water all the time. Storing water is expensive because the tank has to constantly heat and then reheat the water, even when you’re not using it.

Space Saving:

Even if you weren’t concerned about saving money and energy, one of the big advantages of tankless water heaters is the space savings. Tankless water heaters don’t take up nearly as much space as storage-tank water heaters. That’s because they don’t include a storage tank at all. A tankless water heater might be the size of a large computer, perhaps 20″ wide by 28″ tall and just 10″ deep. Depending on the model, tankless water heaters run on natural gas, propane or electricity, and many are designed to be energy efficient.


While a typical tank water heater is expected to last 10 to 13 years, tankless water heaters are estimated to last up to 20 years.
