As a plumbing and heating expert with years of experience in the industry, I've had the pleasure of working with various types of water heaters, including tankless models. When it comes to tankless water heaters, the question of whether they require gas is quite pertinent, and I'm glad to provide a detailed explanation.

Tankless water heaters, also known as on-demand water heaters, are designed to provide a continuous supply of hot water as needed without the need for a storage tank. This is achieved by heating water on the spot as it flows through the unit. The process is efficient and can save energy compared to traditional storage tank water heaters.

Gas Models: The tankless water heaters that we offer come exclusively in gas models, which utilize either natural gas or propane to heat the water. These models are popular for several reasons:


1. Efficiency: Gas tankless water heaters are known for their high efficiency, often rated above 90%. This means that a significant portion of the energy used by the heater is converted into heat for the water, resulting in lower energy costs.


2. Instant Hot Water: Since these heaters heat water on demand, there is no need to wait for a tank to fill up with hot water. This provides an endless supply of hot water, which can be particularly beneficial for households with multiple bathrooms or high water usage.


3. Space Saving: Without the need for a large storage tank, tankless water heaters take up significantly less space, making them an ideal choice for homes with limited space.

Electrical Requirements: While the primary heat source for our gas tankless water heaters is gas, they do require electricity for certain components to function properly.

- Digital Remote: Many modern tankless water heaters come with a digital remote control that allows users to adjust the temperature settings and other features from a distance. This remote requires electricity to operate.

- PC Board: The programmable control board, often referred to as the "brain" of the heater, is an essential component that requires electricity. It controls various functions of the heater, including the ignition process and temperature regulation.

- Electric Direct Ignition: Unlike traditional water heaters with a stand-by pilot light, tankless models use an electric direct ignition system. This system ignites the gas when needed, eliminating the need for a constant pilot light and further increasing energy efficiency.

In summary, while our tankless water heaters are designed to operate primarily on gas for heating water, they do require electricity for the digital remote control, the programmable control board, and the electric direct ignition system. This combination of gas and electricity ensures that the heater operates efficiently and effectively, providing a reliable source of hot water for your home.
