Domestic hot water heat pumps – generating hot water intelligently & efficiently
Hot water without fossil fuels for heat generation? With a domestic hot water heat pump, you can use existing energy sources from air or water to heat your drinking water. Whether in a single-family home, apartment building, or as an addition to an existing heating system, our systems reliably provide hot water up to 65 °C and can reduce the energy required for hot water preparation.
Whether for new construction, renovation, or individual apartments, alpha innotec offers domestic hot water heat pumps for different requirements.
What is a domestic hot water heat pump – and how does it work?
A domestic hot water heat pump extracts heat from ambient air or water and transfers it to your drinking water. The principle is similar to that of a conventional heat pump:
- The heat pump extracts heat from air or water
- A refrigerant circuit raises the temperature.
- The drinking water is heated in the integrated storage tank.
The big advantage: You can prepare your hot water independently of your space heating system and use available environmental heat, for example from exhaust air, indoor air, or groundwater.
The BWP series – compact, quiet & efficient
The BWP series from alpha innotec comprises air-to-water heat pumps used exclusively for hot water preparation. They are suitable for single-family and two-family homes.
Thanks to the integrated hot water tank, they provide hot water up to 65 °C and are designed for quiet operation.

Exhaust air utilization & ventilation function
Washing machines, freezers, and dryers release heat into the air in your home. Our domestic hot water heat pumps can use this available heat for hot water preparation.
An additional advantage: In recirculation mode, excess moisture can be removed from your bathroom, kitchen, or basement. Alternatively, outside air can also be used as an energy source.
Plug-and-Play & PV-ready
The pre-wired plug-in system and flexible components make installation quick and easy. The BWP can also be integrated into your photovoltaic system, allowing you to use your own solar power directly for hot water preparation.
WWB water/water booster – the decentralized domestic hot water heat pump
The WWB is suitable for apartment buildings with central heating systems. Each residential unit receives its own decentralized domestic hot water heat pump with integrated storage tank – for an individual hot water supply and transparent billing.

How the booster works
The WWB connects hydraulically to the central heating system and raises the temperature of the heat source to the required level.
Water temperatures of up to 65 °C are possible without the need for an electric heating element. Whether brine, district heating, heating return or groundwater: various low-temperature water sources can be used.
Compact & efficient
Despite its integrated storage tank, the WWB impresses with its compact dimensions and is therefore also suitable for installations where space is limited. In combination with a PV system, your own solar power can be used directly for hot water preparation.
Advantages of a domestic hot water heat pump at a glance
- Efficient: Uses available environmental heat for hot water preparation
