So how do we determine what size tankless hot water heater you need?

Simple. How many bathrooms you have, and the average amount of hot water on demand your household uses.


Should I get, Gas Tankless Hot Water Heater or Electric Tankless Hot Water Heater?

Although both Gas and Electric Tankless Water Heaters are much more efficient than traditional holding tanks, we recommend gas to our clients if possible. Gas Tankless Hot Water Heaters are more efficient and have a higher capacity than electric.


Some households may not have the ability to instal a Gas Tankless Hot Water Heater because you must have a dedicated gas line.


In that case, we can install an Electric Tankless Hot Water Heater and it’s still much more efficient than the traditional Hot Water Heater holding tank.

How does a Gas Tankless Hot Water Heater work?

Pretty simple actually. Natural gas is used to heat the heat exchanger (the fundamental part of every water heater), which then heats the water. From the moment you turn on your shower and the hot water reaches the shower-head it takes less than 10 seconds for the whole process. That’s why is called Hot Water On Demand.
