"This is a great company. I have a 2 family with only 1 water heater, and it needed to be replaced. Chris went over all the options with me and explained everything very well. He helped me figure out the best option for my property with no pressure and no upselling. Matt and his helper were extremely professional and helpful when they installed the new unit. I just can't say enough positive things about them all! When it is so tough to know who is trustworthy enough to hire, it is helpful to know that you can trust Viscarello!!!"

"I recently had a brand new HVAC system installed for both heating and cooling, and I couldn’t be happier with the experience. The team at Comfort Professor was extremely professional from start to finish. They worked efficiently, paid attention to every detail, and left everything spotless when the job was done. The cleanup was perfect, which I really appreciated. Highly recommend them if you’re looking for quality work and a smooth, hassle-free installation!"

"The young technicians who came to my home to installed the new thermostat and move it to another wall in my home were polite and conducted themselves professionally in my home and cleaned after themselves. I very appreciated Uri suggestion when he recommended to me another alternative at the initial visit and gave me a few quotes to choose from. So I'm very happy with ER service and I would rehired these two individuals back to my home. I will definitely recommend ER to other people in my life."

Water Heaters questions, answered by experts

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

The amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.
