Common Questions About Tankless Water Heaters

When it comes to tankless water heaters, homeowners often have questions to ensure they understand how these systems work, their benefits, and how to maintain them properly. Here are some common questions related to tankless water heaters:

A tankless water heater heats water directly as it flows through the unit using heating elements or a gas burner. Unlike traditional storage tank water heaters, which store and continuously heat a large amount of water, tankless water heaters only heat water on demand.

Yes, tankless water heaters may require modifications to your home’s gas line, ventilation, and electrical systems. It’s recommended to have a professional plumber assess your home’s infrastructure before installation.

The size of a tankless water heater is determined by its flow rate, measured in gallons per minute (GPM). Consider your household’s peak hot water demand (number of appliances and fixtures in use simultaneously) to choose a unit with the appropriate GPM capacity.

Yes, a properly sized whole-house tankless water heater can supply hot water to multiple fixtures simultaneously. However, for larger homes with high hot water demand, installing multiple tankless units for different zones might be more efficient.

Yes, gas-powered tankless water heaters require proper venting to expel combustion gases. Electric models do not require venting.

Tankless water heaters should be professionally maintained annually. Maintenance includes cleaning components, flushing the system to remove mineral buildup, and checking for any potential issues.

Electric tankless water heaters require electricity to function, so they won’t provide hot water during a power outage. Some gas tankless models may still work if they have battery-powered ignitions.

Many regions offer energy-efficiency incentives or rebates for installing tankless water heaters. Check with your local utility company or government agency for information on available programs.

This appointment was for an annual service on my new Furnace. Arrived on time, answered any question i had,and completed the service on the Furnace. Tyler also took the time to look at a problem toilet, gave me his thoughts on problem and then provided me a quot to fix. Maffei has generally always done a good job for me.

Tony, Maffei's Comfort Advisor met us at our cold church. He was so careful in checking things out, photographing our failed heating system. And he has gotten back to us in less than a week! Tony and Maffei concluded that Maffei doesn't do this type of project but Tony had several good referrals for us to services that do! Awesome! Thank you!
