KelvinPlus · Heat. Efficiency. Future.

Turnkey large-scale heat pumps.

For professional use: end-to-end support from planning and construction through to service.

01

Three heat sources. One partner.

Air/water, near-surface geothermal or deep heat extraction: KelvinPlus masters all three source systems and selects the absorption technology that is feasible at your site and operates most efficiently.

02

Manufacturer-independent.

We are not tied to any manufacturer. Your plant is built from the best components available on the market, not from a catalogue.

Sourced from the market: European manufacturers preferred
Assessed by efficiency and service life
03

Turnkey.

Planning, construction and service from a single source. You manage no interfaces; you take over a running plant.

One contact for the entire project
Fully operational at handover
04

Profitable. For decades.

What matters is not the purchase price but what your heat costs over the plant’s lifetime. We plan through our customers’ eyes for the best overall result.

Technology · Heat sources

Manufacturer-­independent.
The right source for every site.

We are not tied to any manufacturer and master all three heat sources: air/water, near-surface geothermal and deep heat extraction. For every site, we select the most efficient one.

Air / Water

Heat from the ambient air

No drilling, no land take: the fastest construction and the most flexible siting. Depending on demand profile and noise tolerance, a good choice for short build times and retrofits with limited space. We offer the quietest large-scale heat pumps available on the market, for the sake of good neighbourhood relations.

Working principle Air / Water Air / Water
Near-surface geothermal

Constant heat from the ground

Borehole probes and collectors use the year-round stable temperature of the shallow subsurface for the highest seasonal performance factors. We take care of the land and the feasibility studies.

Working principle Near-surface geothermal Near-surface geothermal
Deep heat extraction

The efficiency of heat from the deep

Borehole probes take us deep down, where we extract heat with environmentally friendly brine. This taps the year-round warm groundwater as the most productive source, wherever hydrology and permits allow.

Dipl.-Kfm. Marc Banasiak

Founder and Managing Director

More than 20 years of entrepreneurial experience in financing and operating heat generation plants. A clear view of plant economics over their lifetime. Expert for our contracting model, in which we own the plants and supply our customers with the heat they need.

Contracting

Purchase heat instead of financing a plant.

Thanks to their technological design and premium quality, our plants are well suited for contracting. We offer this through our subsidiary specialising in contracting.

Together we plan the turnkey heat generation plant. Based on all parameters, our subsidiary prepares an offer with capacity and energy prices. Our expert service department takes care of keeping the plants running as close to perfectly as possible.

Years: the typical term of heat supply contracts, for reliable long-term calculation

Contracting · Heat-as-a-Service

24/7 heat
as a service

We offer our customers a bundle of financing and operating advantages, up to the option of simply purchasing heat, without owning a plant at all.

Through this heat-as-a-service approach, we plan, build, own and operate the large-scale heat pumps, freeing you from the complexity of managing your own generation plant.
