Modulate the power, preserve the silence, control the warmth

A ceramic coating to ensure that your heat pump keeps its looks.

BWT heat pumps are coated with an additional, protective ceramic coating. Waterrepellent and UV stable, it prevents oxidation and staining by dirt or chemicals. Well protected, BWT heat pumps are easy to clean, and remain gleaming, smooth and beautiful for a very long time.

Reversible heat pumps

All BWT Inverter horizontal heat pumps are reversible as standard. BWT Inverter horizontal heat pumps can be used to heat or cool pool water. This feature is particularly appreciated in very hot regions where it can be used to hold swimming pool water at a comfortable temperature or even to lower or maintain the water temperature in aquaculture tanks used to rear and store fish.

Inverter system

On the contrary to a conventional On/Off heat pump that run at a constant speed (100%), the Inverter heat pump compressor can run at between 20% and 100% to adapt to the machine’s operating conditions and outdoor temperatures. In fact, while the outside temperature is low, or while the heating demand is high, the compressor will run at high speed (between 50% and 100%). 

Inversely, while the heating demand is low, notably around the set point, the Inverter compressor will run at low speeds (between 25% and 50%). BWT Inverter horizontal heat pumps automatically adjust their compressor speed to adapt to the operating mode and outdoor temperature. 

There is no need for any intervention by the user. Running at low speeds, inverter compressors are almost noiseless, provide optimal yield and enjoy a longer service life.

Silence

Conventional On/Off heat pumps generate a constant sound power, even when water temperature is around the set point. On the other hand, BWT Inverter horizontal heat pump compressors slow significantly around the set point so that they run much more quietly than a conventional On/Off machine. 

This is particularly important when the heat pump must be installed close to neighbouring properties. Installers should take regulations governing neighbourhood noise abatement in effect in the country of installation into consideration.

Start-up overcurrents

BWT Inverter horizontal heat pumps feature acceleration ramps that exploit frequency variation technology to avoid overcurrents on start-up along with their inherent negative impact on electrical and electronic devices in the home.
