aroSTOP Domestic Hot Water Heat Pump

In News by Thea Vermeulen

The new aroSTOR range of domestic hot water heat pumps features 200 and 270 litre models. It is perfect for additional hot water requirements in larger homes or small businesses where there is a high hot water demand. This new Vaillant heat pump is incredibly efficient and sustainable, using thermal energy to heat hot water. This thermal energy can be collected via an external air duct, or it can recycle hot air from within the room where it’s installed, provided there is sufficient ventilation. The only other energy needed is the electricity to run the appliance.

How does this work?

Heat pump water heaters use electricity to move heat from one place to another rather than generating their own heat like a traditional electric water heater. This makes them two to three times more efficient. Think of a heat pump water heater as a refrigerator working in reverse.

  • A refrigerator pulls heat from inside a box and dumps it out into whatever room it’s in.
  • An electric pump water heater pulls heat from the surrounding air and dumps it, at a higher temperature, into a tank to heat water.

Heat pump water heaters are sometimes called “hybrid” water heaters because, during periods of high hot water use, they can switch to standard electric resistance heat automatically. You can use your unit’s control panel to set the water heater to various settings, including hybrid mode. If you don’t want it to switch over automatically, simply set it to the regular heat pump mode.

Many control panels have multiple settings and modes to maximize energy savings. If both of your kids are showering at the same time in different bathrooms while you’re running the dishwasher, you can switch it to “High-demand” or “Hybrid” mode to get adequate hot water. Hybrid mode is the most energy efficient mode for daily use.
