Price
The Cost to Install a Tankless Water Heater
Factors That Affect Your Cost
- Water heater type: Whole-home tankless units provide hot water to all plumbing fixtures in your home, while point-of-use (POU) units only provide hot water for a single appliance or area (like the kitchen or laundry room). Some homes just need one whole-home unit, while other homes require a whole-home unit paired with multiple POU units. This paired setup supports hot water appliances that are too far from the whole-home unit and those that have high flow rates (like a shower).
- Fuel type: Natural gas water heaters have higher installation costs compared to electric tankless units. Electric water heaters are also cheaper to operate, saving you money on your energy bills. Determine what water heater is best for your home by reading our blog or contacting Patrick Riley | Isley’s.
- Flow rate: Flow rate refers to how many gallons of hot water the unit can provide in one minute. The higher the flow rate, the more expensive the tankless unit. Our plumbers will help you determine what flow rate you need for your family's hot water needs.
- Labor: If the plumber needs to add a gas line or modify your home's plumbing to install a tankless water heater, then the cost to install your tankless unit will increase.
