Water Heaters questions, answered by experts

Yes, hybrid water heaters can be noisy — noisier than traditional water heaters. The sound they produce is often compared to the hum of a dishwasher. Its noise comes from the heat pump’s fan and compressor as they work to pull in and compress the air. While it’s not totally disruptive, especially if the unit is installed in less frequented areas, like a basement or garage, it’s something to keep in mind if you’re sensitive to noise or if the unit will be placed near bedrooms or living spaces.

It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.
