efficiency through wastewater heat recovery

Efficient Heat Recovery through Wastewater
The wastewater heat pumps from revincus use wastewater as an innovative heat source, significantly reducing the energy demand for hot water production. This leads to substantial savings in energy costs and actively contributes to CO2 reduction.

Easy Integration into Existing Buildings
Thanks to the patented K2 wastewater diverter, revincus heat pumps can be installed even in existing multi-family houses without extensive pipe renovations. This technological innovation makes retrofitting particularly attractive and straightforward.


Eligible and versatile
The wastewater heat pumps from revincus are part of regenerative energy technology and are eligible for up to 60% funding. They offer a sustainable solution for various applications, wherever there is a demand for hot water and wastewater generation.

Why do I choose a revincus system?

Reduce energy costs

Wastewater heat recovery keeps the heat in circulation & thus reduces your hot water costs.

Operate heat pumps efficiently all year round

Heat pumps become efficient year-round through wastewater heat recovery and the COP (⌀5) is significantly increased.

Quick Amortization

Within just 8 to 12.5 years Your investment in housing construction pays off.
Even shorter amortization periods are possible in industry and recreational facilities.

Economical from 20 people

Compared to other systems on the market, revincus offers a solution that already Economically feasible for residential construction from 20 people is.

Reduce CO² Emissions

Increase the energy efficiency of your buildings and industrial processes. Reduce CO² emissions by efficient energy technology!

Low Planning and Investment Effort

Compared to common methods, such as deep drilling or surface collectors, the effort to use wastewater as a heat source is low.

Our wastewater heat pumps are used wherever there is a demand for hot water and wastewater is generated.

The Challenge:

CO2 Reduction through Renewable Energy Systems


The increasing demand for renewable energy systems is underscored by global climate goals such as limiting global warming to 1.5°C and achieving EU carbon neutrality by 2050. A radical shift to renewable energies is necessary, particularly in the area of hot water production, which is one of the largest sources of energy for CO2 emissions. Existing systems cause high energy costs for briefly used hot water, which then flows into the sewage system.


The Solution: Heat Recovery from Greywater

Sewage heat pumps use greywater as an effective, year-round available heat source. Greywater accounts for 73% of domestic wastewater and offers enormous potential with an average of 70 liters per person per day at 25°C. Unlike solar energy or air heat pumps, it is independent of season and weather, making it a stable and sustainable energy source.


Efficient and retrofittable: Wastewater heat pumps for apartment buildings

The ability to retrofit heat pumps in multi-family homes without extensive structural changes makes this technology particularly valuable. With a wastewater heat pump, hot water demand and energy costs can often be covered 100%. The result: a sustainable, cost-efficient, and environmentally friendly solution for both existing buildings and new constructions alike.

Heat Recovery from Wastewater with Wastewater Heat Exchangers

Our wastewater heat exchangers use the heat contained in the wastewater to feed it back into your heating system. This saves energy, reduces your heating costs, and protects the environment.

WBS70 Apartment Block Stadtroda

Energy recovery per year: approx. 104,400 kWh

Hospital Krems Industrial Kitchen

Energy recovery per year: approx. 50,000 kWh

Waldbad Hummelhof Linz

Energy recovery per year: approx. 250,000 kWh

Your benefits at a glance:

  • Most efficient heat pumps using heat from wastewater.
    Due to the high supply temperature from the wastewater, particularly efficient heat pumps (COP ⌀5) can be used.

  • Up to 65% eligible for funding.
    Wastewater heat recovery can be credited towards the share of sustainable energy in your building

  • Wastewater heat recovery is efficient all year round.
    High temperatures can be efficiently generated using heat from wastewater, independent of weather and season.

  • High temperature for drinking water.
    The heating of drinking water and thus the high-temperature range can be efficiently covered with wastewater heat recovery. This opens the way to consider air-to-air heat pumps, low-temperature heating, or even infrared as building heating.

  • Economically viable from 20 residents.
    Applies to the living area.

  • Low planning and investment effort.
    Compared to common methods, such as deep drilling or surface collectors, the effort to use wastewater as a heat source is low.
