FAQs
What are the main advantages of installing a tankless water heater in Washburn?
Tankless units heat water on demand, so you never run out of hot water. They are up to 35% more energy-efficient than traditional tanks, saving money on Washburn’s relatively high winter utility bills. Because there is no storage tank, the risk of tank leaks or ruptures is eliminated, and the compact design frees up valuable space in basements or utility closets.
How do I know what size (flow rate) tankless water heater I need for my home?
Sizing is based on the peak gallons per minute (GPM) your household requires. We add up the flow rates of fixtures likely to run simultaneously—such as a shower (2.0 GPM) plus a kitchen sink (1.5 GPM)—and the desired temperature rise (usually 70 °F in Washburn’s colder climate). Our plumbers perform this calculation during a free in-home assessment to recommend the correct model so you won’t experience temperature drops during usage.
Can a tankless water heater be connected to my existing gas or electric service?
Most Washburn homes with natural gas can accommodate a gas-fired tankless unit, but the gas line typically needs to be upsized to ¾" for adequate BTU supply. Electric models often require a 200-amp service and two to four 40-50 amp breakers. During the consultation, we inspect your gas line or electrical panel and quote any necessary upgrades so the installation meets local codes and manufacturer specifications.
What is the average installation cost for a tankless water heater in the Washburn area?
Installed prices generally range from $3,000 to $4,500 for gas units and $2,800 to $4,000 for electric units. The final price depends on unit capacity, venting materials, gas or electrical upgrades, water treatment add-ons, and permit fees required by Washburn Building & Zoning. We provide a detailed written estimate up front and offer financing plans to spread payments over 6–60 months.
How much maintenance does a tankless water heater require?
Unlike storage tanks that may last 8–12 years, tankless units can exceed 20 years with proper upkeep. We recommend an annual service: flushing the heat exchanger with a descaling solution to remove mineral buildup common in Washburn’s moderately hard water, cleaning the inlet screen filter, and checking venting and gas pressure. We offer economical maintenance memberships that include reminder calls, discounted service, and priority scheduling.
Will a tankless water heater work during Washburn’s cold winters?
Yes. Modern units are rated to operate efficiently with incoming water temperatures as low as 35 °F. We set the output temperature (typically 120 °F) and size the unit for a 70–85 °F rise. Freeze protection heaters inside the unit safeguard internal components down to –4 °F during power outages as long as gas or electricity is available. If the unit is installed in an unheated space, we insulate and heat-trace water lines to prevent freezing.
