This year’s Idea House is located in a beach community and has the capacity to sleep 11. Even a large storage-tank water heater would struggle to deliver enough hot water when the house is full. And because the stays of visiting guests may be sporadic, a conventional water heater that is constantly running to keep the oversize tank heated would be expensive to operate.
Go Tankless for an Endless Supply of Hot Water
We knew we needed a tankless water heater. Unlike traditional storage tank units that operate around the clock and can run out of hot water, tankless units can heat an endless supply of water on demand. There’s no need to wait for the tank to heat up more water. Just turn on the shower upstairs and cold water is delivered via pipe to the tankless unit where it passes through a gas burner that almost instantly heats a constant flow of water to the desired temperature.
Voice Activation for Convenience and Savings
Fast Fact: While tankless units never run out of hot water, it is important that you select the right size water heater to ensure it can accommodate your specific hot-water needs. We chose a model that delivers a generous 9.8 gallons of water per minute, which will efficiently allow us to run multiple showers and appliances at the same time.
Recirculation for Instant Hot Water Many people don’t realize that even though these units heat water almost instantly, it still takes time for that hot water to reach the locations where it’s needed. This can result in lots of wasted water going down the drain while waiting for it to reach your faucet. A recirculation system eliminates those problems by pumping cold water in a loop through the pipe and back through the heater. After about a minute, the water in the pipes reaches the right temperature, the recirculatory pump shuts down, and you have hot water the moment you turn on a shower or open a faucet.
Fast Fact: Did you know that nearly a quarter of the average household’s energy spending is devoted to powering hot water? Only heat and cooling cost more. Tankless gas water heaters can save homeowners about $100 a year. And while the price to purchase these units can be almost double that of a storage tank heater, they last two to three times longer with savings that kick in after about six years, making them a smart investment for the budget-conscious homeowner.
On Vacation When You Are
We also like that the Control-R™ mobile app includes built-in timers and schedules allowing for multiple on/off periods. This will allow the future homeowners of our Idea House to put the system into vacation mode when they’re away and even stop a scheduled recirculation event from starting. Another bonus for our cold-climate location: The Rinnai SENSEI offers freeze protection down to -4˚F for indoor units or -22˚ for outdoor units.
There’s a lot to consider before choosing a hot water heater and size matters: Fuel type, the average ground water temperature where you live, local building codes, and how much hot water your family uses will all influence the size of the system you need. Ask your installer which Rinnai model is right for you.
