FAQs
					 What Is a Tankless Water Heater and How Does It Work? 
							
			
			
		
						
				Traditional storage tank water heaters heat and store a large quantity of water in a big tank until you’re ready to use it. As the heated water in the tank is used up, more water is introduced where it’s heated and kept at its set temperature on standby until it’s needed.
Tankless systems, on the other hand, heat water on demand using a heat exchanger. Activated when you turn on your shower, washing machine, dishwasher or faucet, the tankless water heater efficiently heats cold water to a set temperature. Water is heated as it passes through the coils and exits from the hot water outlet pipe to where it’s needed in your kitchen, bathroom or laundry room.
Once hot water is no longer needed, cold water stops entering the tankless water heater and the appliance turns off until it’s signaled to turn back on.

					 How Much Will a Tankless Water Heater Save Me? 
							
			
			
		
						
				The amount you save will depend on how much water you heat, what type of tankless water heater you choose and how efficient the water heater you are replacing is. Generally, depending on the equipment efficiency and your family size and usage, a tankless water heater could mean hundreds of dollars saved over the unit’s lifetime, compared to a standard tank.

					 Is One Better than the Other? What Should I Choose? 
							
			
			
		
						
				Both natural gas or propane tankless water heaters can provide all the hot water your entire home will need. In fact, our tankless water heaters can use either fuel source. There is no conversion kit needed. They can also function in or outside by easily switching the venting type.
A tankless water heater is a great option no matter whether you have natural gas or propane, or wherever you want to install it.

					 Are There Any Special Requirements in My Home to Have a Tankless Water Heater Installed? 
							
			
			
		
						
				Whether you choose a natural gas or propane tankless water heater, a home heating expert will need to ensure your home can easily accommodate a tankless water heater since tankless water heaters have special venting and gas line requirements. The installation of any gas appliance must be performed by a licensed technician.
If you live in an area with hard water, which is rich in minerals like magnesium and calcium, you may want to purchase a water softener to remove hard water minerals from the water before it enters the tankless water heater. This will also reduce scale buildup in other appliances around your home.
