How to use your Vaillant Air Source Heat Pump

Heat pumps operate rather like a fridge. Only rather than cooling, they operate in reverse and heat your home instead.

Like fridges, heat pumps are designed to operate continually on low power to gently heat your home.

Unlike a boiler, heat pumps operate at much cooler temperatures which means that the temperature of your radiators will be approximately 45 degrees Celsius rather than the typical 80 degrees Celsius that you may be used to from a boiler.

Due to these lower running temperatures, it is necessary to run your heat pump all of the time rather than setting an ON/OFF timer for when you return home from work for example. Running your heat pump continually, will ensure that it operates at its most economical and that your home remains at a comfortable temperature.

Rather than turning your heat pump off, we recommend that you program a "set back" temperature instead. This is done using the VR700 user controller. For example, when the property is unoccupied or at night time, simply set the temperature back a little by 3 or 4 degrees Celsius from your normal comfortable set point. So, if you normally require the room to be 21 degrees Celsius, set it to 17/18 degrees Celsius at night.

Turning your heat pump electricity supply off completely could damage the unit and will also cost you more to reheat your home from its lowest temperature.
