"Jeremy was very responsive and informative. I had a couple of other quotes that involved various iterations of "replace the old water heater and add these other features at the same time", and we were able to talk through the suggestions and determine what was really necessary. The final quote was very competitive, the new water heater is working great, and the installation itself was fast and without any problems that they couldn't solve without me!"

"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"My husband is ill and I needed help. My water heater wasn't working so I called High Speed Plumbing. Donald was wonderful ! He arrived earlier than expected and was very personable. He found the problem quickly and replaced the water heater and some electrical problems. I had smelled plastic burning so I was very concerned. I now have hot water and am not concerned about a fire hazard. I would recommend this company and will call Donald the next time I have an issue. Great experience !!"

"The only contractor that conducted an analysis of the house for heating and cooling load and checked the adequacy of the vents. The salesman was very competent and professional. The quality of the workmanship was excellant."

Water Heaters FAQs, answered by experts

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

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.

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

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.
