"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."

"We scheduled an appointment with Johns Plumbing to get an estimate for a couple of non-emmergency issues including water heater replacement and faucet installation. Price was fair and we decided to go with them. Plumbers were working fast, and they completed all the work within one day. I would recommend Johns Plumbing to everyone."

"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

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

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.

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.
