Maximizing Space and Efficiency with a Tankless Water Heater

Mar 31, 2025 | News

A Rinnai tankless water heater is a great way to save space and energy while ensuring you always have hot water when you need it. Our latest installation shows how these systems can fit into tight spaces like storage rooms, making them perfect for smaller homes and apartments.

Few things are more frustrating when it comes to home comfort than running out of hot water. Traditional water heaters take up valuable space and store hot water even when it’s not being used, leading to energy waste. That’s where a tankless water heater, like the Rinnai system we recently installed, makes all the difference.

A Smart Solution for Tight Spaces

For this installation, we mounted the Rinnai tankless water heater in a small storage room above the bathroom and laundry area. Unlike bulky traditional tanks, this compact system fits neatly into tight spaces, freeing up room for storage while still delivering reliable hot water. Plus, its energy-efficient design helps homeowners save on utility bills.

How It Works

Tankless water heaters heat water only when needed, eliminating the need for a large tank and reducing energy waste. Here’s how the process works:

  1. When a hot water tap is turned on, the system detects the water flow.
  2. A flame ignites, heating two heat exchangers.
  3. Cold water preheats as it moves through the secondary heat exchanger.
  4. Water continues to heat as it passes through the stainless steel primary heat exchanger.
  5. Hot water exits the unit and travels to the faucet or appliance where it’s needed.
  6. The flame automatically adjusts to maintain the set water temperature.
  7. Once the hot water tap is turned off, the flame shuts down, saving energy.
