Q: How do hot water heater expansion tanks work?

• <div><p>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.</p><p>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.</p></div>

Q: Can a water heater element be replaced without draining the tank?

• <div><p>No, you&rsquo;ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don&rsquo;t always need to drain it completely. If you&rsquo;re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you&rsquo;re replacing the lower element, you&rsquo;ll need to drain the whole thing. </p></div>

Q: What size tankless water heater to replace a 50-gallon water heater?

• <div><p>A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater. </p></div>

Q: What is the difference between a boiler and a water heater, and can they be used together?

• <div><p>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.</p><p>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.</p></div>

Q: Is ventilation necessary for water heaters?

• <div><p>Not all <a href="https://www.angi.com/articles/types-of-water-heaters.htm">types of water heaters</a> require a venting system. Electric tankless water heaters don&rsquo;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. </p></div>

Customers say: Quick response

"Long Holiday Weekend and my hot water heater quit. We had just moved in too. That should have been caught in inspection. Oh well. By chance we had HVAC repair scheduled and they offered to look at the water heater, but My Guy already squeezed us into his schedule. I'm so glad he did. His price came in lower than the HVAC service person's quote. My Guy provided options for repair vs replacement. Knowledge is power, and I feel we were given all the information up front. We opted to replace. He showed us how to operate the water heater and told us the schedule for maintenance to get the longest use of our new water heater. I highly recommend My Guy. We'll have him back again when we replace the sink and dishwasher."

Water Heaters FAQs, answered by experts

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.
