"We had our water heater replaced by The Water Heater Company and the service was excellent from start to finish. The technician, Mike P., was professional, on time, and extremely knowledgeable. He explained everything clearly, completed the installation efficiently, and made sure the area was clean before leaving. My new water heater is working great. We really appreciate the quality of work and the attention to detail. We highly recommend The Water Heater Company especially if you want a smooth, stress-free water heater replacement done right the first time."

"Found me the right size water heater, a few days before Thanksgiving and had it installed within 2 hours. Clean and efficient and Bradford White gas water heaters are American made. Built to last. Daniel Westereng did a great job with the install. Clean, fast, thorough and polite."

"Only good things to say about McLay Services! From scheduling the services call to getting the work done. The technician was up front with pricing and told me only what needed to be repaired on my water heater. He even did a free safety check on my furnace and found a dirty air filter that needed replacement. I will be calling again in the future."

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

Water Heaters questions, answered by experts

Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

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.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.

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.
