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: Can you ask a pro what’s the best breaker size for your water heater?

• <div><p>If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won&rsquo;t overload, which could lead to fire and other damage.</p></div>

Q: Which types of gas appliances might require installation or replacement services?

• <div><p>Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.</p></div>

Q: Are water heater pans required by code?

• <div><p>Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.</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>

This was a big job. It took them several months to get the crews out to do the work, but once they started, it all moved very quickly. They had to do some extra work because of water damage discovered when they removed the old siding, but the charge for repairs was lower than expected.
