Are hybrid water heaters noisy?

• <div><p>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.</p></div>

Do both my boiler and water heater need their own expansion tank?

• <div><p>Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater. </p></div>

Can you switch to a tankless water heater from a heater with a tank?

• <div><p>Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.</p></div>

I had this unit installed in my home because it only heats water when you want it. You get a rebate from taxes because it s an energy saver. This company is wonderful. They installed this unit, and they also do the regular check up in my heating and air conditioner unit. They are very punctual.

"BUYER BEWARE! Had a pipe leak within my wall. Caught it fairly early with minimum damage. The Roto Rooter rep Brian came out and inspected and said I needed water mitigation based off the moisture in my walls. When I say the leak wasn't that bad, it really wasn't! He stated that my insurance company would cover it all and that he deals with my particular company all the time and not to worry. I obviously was taken back by the cost of almost 4k! Fast forward, my insurance company are questioning duplicate charges and Roto-Rooter is saying I owe almost 3k or a lien will be placed on my property! This whole water mitigation is a scam and the salesman did not tell the truth. They should have picked up their fans a lot earlier than they did. I'm sure they were trying to milk all the money they could. Over 5k for a bunch of fans in my home. I WILL NEVER REFER ANYONE TO THIS PLACE! Contacting my lawyer and will have my day in court if necessary. BUNCH OF SCAM ARTISTS IF YOU ASK ME!"

Water Heaters questions, answered by experts

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit.

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.
