Loading…Heat Pump Water Heaters
A heat pump water heater is used for energy-efficient domestic hot water preparation. Unlike a standard electric water heater, a heat pump water heater uses heat from the air to bring the water inside the integrated storage tank up to temperature.
At Hewa, you will find heat pump water heaters for homes, technical rooms, renovation projects and business applications. When selecting the right unit, check volume, hot water demand, air duct connection, electrical capacity, sound level, installation location, legionella program and available installation space.

Heat pump water heaters for independent hot water supply
Heat pump water heaters prepare domestic hot water using an integrated heat pump. The unit extracts heat from ambient air or exhaust air and uses this energy to heat the water inside the storage tank. This makes a heat pump water heater an independent and energy-efficient solution for hot water comfort.
Selecting a heat pump water heater
The right heat pump water heater depends on the number of users, daily hot water demand, available installation location and air intake or exhaust air setup. Volume, electrical connection capacity, heat-up time, sound level, legionella program and possible electric backup heating are also important selection points.
For other domestic hot water solutions, also review domestic hot water tanks for heat pumps, indirect boilers and the broader category buffer tanks and boilers.
Important when choosing heat pump water heaters
- Match the tank volume to the number of users, draw-off points and hot water consumption
- Check whether the unit uses room air, outdoor air or exhaust air
- Check installation location, air duct connection, condensate drain and service access
- Check electrical capacity, backup heating, heat-up time and legionella program
- Check sound level, minimum room temperature and available ventilation
- Check safety components, inlet combination, expansion provision and pressure rating
- Have installation, water connections and electrical connection carried out by a qualified installer
Applications within heat pump water heaters
Homes and renovation
For energy-efficient hot water supply in existing homes where an independent domestic hot water solution is required without a separate external heat source.
Technical rooms
For installation in storage rooms, garages, utility rooms or technical spaces where sufficient air volume, condensate drainage and service access are available.
Business applications
For small commercial buildings, workshops or project-based installations where domestic hot water needs to be generated efficiently and locally.
Integrated heat pump, storage tank and air-side connection
A heat pump water heater is technically different from an indirect boiler or a domestic hot water cylinder for an external heat pump. In a heat pump water heater, the heat pump technology is integrated into the unit itself. This means domestic hot water does not primarily need to be heated by a separate boiler, solar thermal system or outdoor unit.
When selecting the right unit, the air-side operation must be checked carefully. Some units use ambient air from the installation room, while others can be connected to air ducts. Always check minimum air volume, duct diameter, condensate drain, sound output, electrical connection and service space around the unit.
Frequently asked questions about heat pump water heaters
What is a heat pump water heater?
A heat pump water heater is a water heater with an integrated heat pump. The unit uses heat from air to bring domestic hot water inside the storage tank up to temperature.
What is the difference compared with a domestic hot water cylinder for a heat pump?
A domestic hot water cylinder for a heat pump is heated by an external heat pump or heat source. A heat pump water heater has the heat pump technology integrated into the unit itself.
Where should a heat pump water heater be installed?
A heat pump water heater must be installed in a location with sufficient air supply, condensate drainage, load-bearing capacity, electrical connection and service access. Always check the installation manual of the unit.
Does a heat pump water heater have electric backup heating?
Many heat pump water heaters have electric backup heating for peak demand, faster heat-up or legionella programs. Check capacity and control setup for each unit.
What should an installer check during installation?
Check air intake, exhaust air, condensate drain, inlet combination, water connections, electrical connection, sound level, free space around the unit and technical documentation.
