"They were up front with what is wrong. Provided explanation of the quote. Asked permission to get access to places. They explain the reasoning for the cost and the risks if ignored. Pricing was fair. Went above an beyond to solve the water heater issue we had. Even calling in an electrician to help with a fix. They were on-time to early on their scheduled appointments. Excellent customer service."

"Pohlman responded quickly when my water heater leaked and quickly replaced it at a competitive rate. I asked for multiple quotes and they were one of the first to respond. I appreciate the work, although I would have preferred to know which water heater was being installed before they put it in."

"It went amazing. Paid the extra bucks for emergency service, because of our smallish waterfall, looking leak, sprouting from a bathroom pipe, enough to puddle water onto our basement/laundry room floor. Initially, spoke to Chris, who was pleasant and upfront with the per hour fees, for emergency services. He sent us Tim, who was hesitant at first, due to the location of the leak, but his experience and knowledge, enabled him to decipher the location of our leak and fix it. A quick trip to Lowes, where he promptly returned and in 90 minutes, the job was done. A week later and the valve is bone dry. Yay!!!"

"Andrew and his team were great from start to finish. He was able to match pricing, which initially was a concern, and the speed and quality of installation has been more than worth it... The installed system has been working flawlessly especially as the temperatures started dropping. I will definitely use them again, and at other locations. Andrew is very knowledgeable, easy to talk with and ask questions, and a perfectionist at what he does.. this quality-oriented approach really shines through and makes Amazing Heating & Air stand out high above the competition."

"Prime Plumbing provided excellent customers service from the beginning to the end. Rob was very thorough when he came out to provide estimate, financing options and gave good explanation of what was needed to replace my direct vent hot water tank for my condo. Rob was also the one who installed the hot water tank and did an excellent job. Direct vent hot water tanks are much more expensive than your standard hot water tank, so it was pricey. I initially found Prime Plumbing on Angie's list and I would recommend them for your plumbing needs. I'm a single female in my early 60's. I did end up using my own financing because their finance company interest rates were way too high for someone with excellent credit. Do rate comparison first."

Water Heaters FAQs, answered by experts

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.
