A traditional water heater stores water in an insulated tank for when it’s needed. The only difference is how the water heater heats the water that is stored in the tank. They can use various energy sources including electricity, gas, oil, or even solar energy to heat your water. Which water heater is best for you depends on such factors as availability, cost, and efficiency.
Electric tankless water heaters are the favorites of the tankless. They are easy to install, operate and provide maintenance to. Again tankless units don’t house any water, so how does a tankless unit work? When you turn on the warm water tap the cold water intake pipe allows cold water to flow in from the supply pipe and enter the tankless unit. The water flow rate is detected by a flow sensor, which then triggers the heating elements. This way, your heating element doesn’t have to work nonstop to keep your water hot, it shuts off immediately as its water flow stops. The water heats up quickly as it moves over the heating electrodes and nearly instantly reaches the desired temperature. The hot water valve on the unit allows the heated water to exit and flow to your faucet.
Utilizing a gas burner for on-demand water heating, these systems are offered in both natural gas and propane variants. Ideal for households relying on gas for water heating, tankless water heaters generally outperform their electric counterparts in terms of output.
Upon opening a hot water tap, cold water enters the unit through the inlet pipe. A flow sensor detects the water flow rate, triggering the ignition of the gas burner. Fueled by natural gas or propane, the burner heats a heat exchanger. Water circulates through this exchanger, absorbing heat from the gas flame and rapidly reaching elevated temperatures. The now-heated water exits through the hot water outlet, ready to be delivered to your faucet or appliance.

Another notable feature of tankless units is their precise temperature control, allowing users to set their preferred water temperature with precision. Although the initial installation cost may be higher compared to traditional water heaters, the long-term savings on energy bills and the enhanced convenience they bring make tankless water heaters a financially sound and practical choice for many homeowners.
The decision between electric and gas tankless water heaters hinges on factors such as hot water demand, energy source preferences or availability, and specific installation requirements. Ensuring the unit is appropriately sized to meet household needs is crucial, and consulting with a professional during installation is recommended for both safety and efficiency.
