A tankless water heater doesn't heat up a full tank with hot water each time you turn on the hot-water faucet. Only when the hot-water faucet opens, tankless water heaters heat up water. This system of water heating is also called "on-demand water heating".

Although a tankless water heater is more expensive than a traditional tank heater, the savings in energy can be enough to cover the cost of the heater within three to five years.

The main benefit of a tankless water heater is that you always have hot water available for your needs. You should ensure that you get enough hot water for your needs.

Tankless water heaters can heat up to 200,000 BTUs. They can heat up to 9.5 Gallons of hot water per hour and supply hot water to two or three faucets, including shower faucets, or other appliances simultaneously.

Are you looking for gas-fired or electric?

Two PVC vent pipes must be run from the wall to a gas-fired device. There are also electric models that do not require ventilation. An electric unit must be connected to an electrical service box of 240 amps if you want to use it.

Choose the Right Location

Choose the location where you will install the unit. It is a good idea for the unit to be placed near your old tank-type water heater. It is important to place the unit close to the main cold water supply pipe and near the hot water pipe leading to appliances and faucets.

You will need to run gas lines because this unit is gas-fired. Vent pipes will be required to run through the roof or out of the wall. You will need to add an electric power outlet if there isn't one nearby.
