Does a water heater deliver hot water?
No matter the brand or type (tank or tankless), a water heater alone will not deliver instant hot water to a shower, faucet or appliance. The correct features, capabilities, location and technology must be in place to enable the immediate delivery of hot water. Below are a few factors that may impact the delivery time for hot water to reach your fixture.#N#Capabilities: Certain product features help facilitate instant hot water delivery. For example, a built-in recirculation pump paired with a recirculating piping system returns unused hot water back to the water heater for re-heating instead of going down the drain.#N#Proximity: If you do not have a recirculation pump with the necessary piping system installed, the proximity of the water heater to the water fixture will impact how quickly the fixture receives hot water. Hot water will be delivered faster when the water heater is closer to the fixture because the length of piping in between the two is shorter.#N#Temperature: The temperature of the piping between the water heater and the location of the water fixture is another factor that may impact hot water delivery. Climate, weather, seasonal changes and the path of the hot water pipe can all have an impact. For example, during a northern United States winter, 40 feet of piping in a crawl space without recirculation assistance will take longer to deliver hot water than 40 feet of piping in an attic during a southern United States summer.#N#Learn how technology can help deliver instant hot water to a fixture.
