A tankless, or on-demand, water heater only heats water when you need it. These heaters can be installed in a closet, on an exterior wall or another convenient place inside your home and can heat your whole home or a single point of use. With point of use, you can have a separate water heater designated for a shower, sink or appliance.
These water heaters give you an endless source of hot water, all while saving money on energy costs by not heating and reheating the same tank of water. While the initial purchase and setup is more expensive, most homeowners find, through the energy savings, the appliance pays for itself after a few years.
Since tankless water heaters don’t store heated water, these instant hot water heaters work like this:
- When opening a hot water tap, or starting the dishwasher, the tankless water heater recognizes the need for hot water and starts the heating process.
- The temperature of the incoming water is used to calculate how much heat the burners must produce to deliver water at the desired temperature. When the demand for hot water ceases, the unit shuts down and uses no energy, waiting until more hot water is needed.
- The end result: hot water that isn’t limited to what’s available in your tank.
Benefits of a Tankless Water Heater with PHD Heating & Cooling
Instant Hot Water
You can turn any water source into hot water on demand. You aren’t limited to the amount a storage tank heater can hold. Whether you’re washing the dishes, washing your clothes or drawing a hot bath, tankless water heater technology will supply endless hot water to your lifestyle demands, even if you do them all at once.
Lower Energy Bills
Take advantage of up to 40% energy savings with a tankless water heater. Units are designed to be highly efficient and only heat water when it’s needed.
Longevity
Tankless water heaters typically last up to 20 years, twice as long as a tank-style unit.
Space Savings
Traditional water heaters can take up to 16 square feet of valuable floor space. Tankless water heaters are about the size of a carry-on suitcase and can be installed on virtually any wall inside or outside of your home.
Clean, Fresh Water
Traditional water heaters can build up rust and scale inside the tank, where the hot water you use for bathing and drinking is stored. With tankless water heaters, you’ll always experience fresh, clean water that’s heated on demand as it passes through the unit.
