Product Line Up
Combined heating and power stations
Tailor-made energy concepts for applications requiring a medium output in municipal buildings, and industrial and commercial enterprises.
A gas driven combined heat and power unit (CHP) generates heat and power simultaneously. They are sized to suit residential units and commercial operations. On the heating side, the CHP unit operates in parallel to a boiler. For generating heating water and DHW heating, both heat sources are connected to the heating system.

Domestic hot water cylinders
Domestic hot water cylinders, 80 to 1000 litres
The demand for hot water is completely different in every household. One factor is the number of residents and another is their bathing and showering habits. For example, several people in one household frequently go to work and school at the same time, so lots of hot water needs to be continuously available for the shower in a short space of time. Those who prefer a bath will also want to have enough hot water to fill the tub. Finally, the DHW cylinder should also provide sufficient water if, in an apartment block for example, hot water is drawn from more than one outlet at the same time. The Vitocell DHW cylinders fulfil these requirements in every respect and can also meet every aspiration where equipment levels are concerned. In all instances, the installation of a solar thermal system is recommended to save energy and heat the water without cost.

Air-conditioning technology
Fresh and pleasant air – particularly on hot heavy summer days – is pure pleasure. For quite some time now, we have become used to advanced technology enabling us to enjoy a pleasant atmosphere in our cars, in hotels, as well as in offices and business premises. This has lead to our desire to experience the same higher level of comfort produced by a fresh atmosphere in our own homes.

There are good reasons for that. Not only do we value a pleasantly cool atmosphere inside when it’s hot outside in summer, but there is also the question of health and the ability to perform, for which air conditioning is important. The optimum ambient climate is achieved on average at a room temperature of approx. 21 °C. In addition, a relative humidity around 50 % is also ideal. However, these values fluctuate severely in the course of the day and thereby influence our performance, concentration and our feeling of well-being. It is good to know then, that advanced air conditioning systems provide the necessary balance by enabling ideal control – day and night. Not only the temperature that is, but also the relative humidity. A pleasant side effect that allergy sufferers will appreciate is the multiple filtering of the ambient air through dust and charcoal filters, as well as electrostatic filters.

What is also good to know is that this bonus of freshness and well-being is delivered by technology that users will hardly perceive. No draughts and with the lowest possible noise level – yet in a package that falls into the highest energy efficiency category.

Large heat pumps up to 1500 kW
With technical expertise, high manufacturing ability and many years of experience, KWT is the heat pump manufacturer of choice for every special application. KWT works together with its clients to develop solutions that are based on more than 30 years' experience, that will meet practical, everyday needs, and that will overcome any and every challenge. All deadlines and costs arranged can be relied on, with no unexpected surprises. All systems are designed and built based on our customers' performance definitions. All heat pumps and geothermal probes verify this performance on the test bed and in practice.
 
Geothermal probes
KWT brine/water heat pumps – designed with expertise and built with quality.
Geothermal probes are durable, maintenancefree heat sources. In conjunction with heat pumps, they provide energy for heating, but are also the ideal heat exchanger for natural cooling. In both cases, KWT brine/water heat pumps utilise the constant temperature in the ground.

DHW heating
DHW temperatures above 60 °C are often needed. However, especially with larger heat pumps, the demand for DHW heating accounts for the lesser proportion of total output. With multi-stage heat pumps or hot gas decoupling, KWT heat pumps can provide the ideal solution to meet this demand. The use of special safety heat exchangers guarantees global potable water requirements are maintained.

Water/water heat pumps
High grade components make KWT water/water heat pumps powerful and reliable in
borderline areas.

Groundwater at 8 to 12 °C is a very rich heat source for a heat pump, as the temperature level is high all year round. However, fluctuating water qualities usually require special heat exchangers (evaporators) if you wish to avoid having intermediate circuits.

Stainless steel tubular evaporators
KWT heat pumps for groundwater or surface water are equipped with high grade stainless steel tubular heat exchangers. The benefits are obvious – the evaporator has a large volume and generously sized surface area, so the border regions are not vulnerable to icing up. Light floating parts are simply flushed through with the medium, and aggressive chemical fluids have little destructive effect on the high grade stainless steel.
Air/water heat pumps
KWT air/water heat pumps for heating and cooling, in conjunction with conventional heat sources, are an economical solution where cooling is required.
Air is readily available as a source of heat. However, even when cooling is required, air can easily absorb the extracted heat. KWT air/water heat pumps make particularly efficient use of air temperatures down to about 5 °C, with which they can cover up to 50 % of the annual heat demand.

Heating and cooling
Air/water solutions from KWT are suitable for heating and cooling. In both cases, the highest level of efficiency is guaranteed thanks to variable speed DC fans. The special design of the air heat exchangers, with gaps twice as wide as in conventional chillers,
optimises heat transfer, lowers the pressure drop of the air flow rate, reduces noise and ensures a fast and efficient defrost process.

 
Special systems
KWT special systems are built precisely in accordance with your requirements, they are reliable in operation, and have been used successfully as system components for many years.
Waste water and waste heat from industrial processes contain a great deal of energy, which is only seldom used. KWT has the right expertise to exploit this energy. Even for extremely low outside temperatures of minus 40 °C up to plus 35 °C, there is a matching heat pump in the KWT range.

DHW heating
Waste water from hotels and leisure complexes is usually at a residual temperature
of 25 to 35 °C. At the same time, however, such complexes also require a large amount of fresh hot water. KWT, with its ideally suited heat pumps is best placed to make use of this waste heat and so is the perfect partner for such projects. Their heat pumps are highly efficient and supply a water temperature of 60 °C.
Engineering and service
KWT guarantees the components and assemblies in its products will work seamlessly together – from individual support in designing the system right through to maintenance.

Heat pumps from KWT guarantee efficient and reliable operation. Following installation, KWT engineers or Viessmann service companies commission the system, check its output and reliability, document all the work and tests carried out, and instruct the future operators.

As the only heat pump manufacturer in Switzerland with a complete value chain within its own company, KWT guarantees the components and assemblies in its products will work seamlessly together – from individual support in designing the system right through to maintenance. Outside Switzerland, these services are provided by Viessmann.

Photovoltaic systems
If you produce your own power, you can receive a guaranteed remuneration from your power supply utility over 20 years. This is governed by the Renewable Energy Sources Act (EEG) [Germany], which states that energy providers are obliged to accept the renewable power and feed it into their grid. Power for your own consumption continues to be drawn from your local power supply utility at the usual tariff. The feed-in remuneration for environmentally friendly photovoltaic power is higher than the consumption tariff. This difference, together with the public loans programmes, contribute to economic finance for a photovoltaic system. In addition, a number of regional subsidies are available. For up-to-date information, see the subsidies database at www.viessmann.de

Vitosol 300-T
Vacuum tube collector

First class high performance vacuum tube collector
The Vitosol 300-T high performance vacuum tube collector operates according to the proven heat pipe principle. It consequently offers particularly high operational reliability. One of the specific applications of the Vitosol 300-T is in systems with long phases of high solar irradiation without heat transfer, so called stagnation phases. The dry connection of the heat pipe tubes inside the header and the integral temperature limiter ensure particularly high operational reliability.

Heat pipe principle for high operational reliability
In heat pipe systems, the solar medium does not flow directly through the collector tube. Instead, a process medium, which circulates in the copper pipe below the absorber, evaporates when subjected to solar irradiation, and transfers the heat to the solar medium via a heat exchanger.
