2 Vaillant heat pump technology 4 Ground source heat pumps 6 Domestic hot water preparation 8 Technical data 9 Why do you think Vaillant is Europe s best-known brand in heating? Because we offer every client a customised energy solution and make every home comfortable? Because we are coitted to greater energy efficiency and renewable energy sources? Or because our trade mark is a hare? That is all true, but it s not the whole story. We believe the reason is: Because Vaillant thinks ahead.

3 The Vaillant brand Vaillant is the brand providing answers for tomorrow s world. Ahead of our time since 1874 When Johann Vaillant patented the world s first gas bath boiler for domestic hot water in 1894, twenty years after becoming established, he started a small revolution. In 1905 he invented the first wall-hung boiler: the Vaillant Geyser, and in 1930 the first gas-fired water heater with the characteristic Vaillant design came into being. In 1961 we introduced the first gas-fired circulation water heater and, in 1967, the first combined heating and hot water system in one unit. In 1995 we were able to offer the first in-house developed wall hung boiler with high efficiency condensing technology, in 2004 our first mini-chp, in 2006 the first self-produced heat pump and in 2010 the unrivalled zeolite gas heat pump. Vaillant has always had the edge. Because Vaillant thinks ahead. Quality made in Germany The hallmark of the hare is a promise of quality that applies to every product and service with the Vaillant name. Vaillant quality is perfection in every detail: We spare no effort in the design and production, so you can effortlessly operate your Vaillant system in your home. We manufacture our products mainly in Germany for customers around the world. Our range includes gas, oil and pellet heaters, solar systems, heat pump systems, the zeolite gas heat pump, the latest combined heat and power systems for every application, and also hot water cylinders, gas and electric water heaters, ventilation systems and programable controls to ensure that everything works perfectly. Because Vaillant thinks ahead. For today, tomorrow and the future Research and Development in the Vaillant Group, with over employees, is one of the largest and most creative of those in our industry. We are particularly focused on developing new technologies for sustainable energy supply, including the combination of fossil and renewable sources of energy in efficient integrated systems and the dual use of energy in combined heat and power systems. In Germany, we are currently introducing the world s first micro-chp system with a gas-burning engine, and we are working on our first fuel cell heating appliance. This is how we are shaping the future of heating technology. Vaillant is the brand providing the right answers to all questions related to heating, living comfort and new energies.

4 How exactly does a heat pump work? Heat from outside for inside There is no more abundant, natural energy than solar energy, which is stored in the form of heat in the air, in the ground and in groundwater. This energy is available everywhere, free of charge; it will never be exhausted and you can use it all year round to heat your house. Because even cold air and cold ground still contains a good deal of heat energy. In fact, every medium whose temperature is above absolute zero, that is above 273,15 C, contains heat energy. And it can never get that cold anywhere on earth! Energy, a gift from nature Heat pumps increase the temperature of environmental heat you could say they pump it up to a temperature suitable for heating. To achieve this, you have to supply a quarter of the required heat energy in the form of electricity, while the remaining approximately 75 % is free. Of course, it is also true that the smaller the temperature difference between the outside heat source and the required heating energy inside is, the less energy is required to balance the difference out.

5 Environmental heat Modern technology from Vaillant A heat pump operates in a cycle in which a refrigerant with a very low boiling point circulates and constantly undergoes the four steps of the cycle. It evaporates and in so doing takes up energy, and then condenses and in the process releases energy. This is how it works: From ground with probe or flat collector With a Vaillant heat pump, you can choose your heat source: Ground heat Is extracted using a geothermal probe that leads vertically into the ground, or with a ground collector that is horizontally installed at 1.20 to 1.50 m depth. Our heat pump technology is proven technology and an efficient system. Evaporation. Environmental energy is supplied to the refrigerant in the evaporator. The coolant changes from a liquid to a gaseous state. Compression. The gaseous refrigerant is strongly compressed by using a compressor. (This requires electrical power.) As gas automatically heats up if it is compressed, the refrigerant becomes hot. Good for the environment, good for you A heat pump makes you independent from fossil fuels and their constantly increasing costs, because you use free, inexhaustible energy of your ground instead of externally supplied energy with its ever increasing costs. And without even the slightest emissions arising from heat generation, you will always have a comfortable, warm home. Condensing. In the condenser, the hot gaseous refrigerant gives up its heat to the heating system. Of course, the gas thus becomes cooler and therefore liquid again. Expansion. In the expansion valve, the refrigerant is decompressed, i.e. the overpressure is reduced and the refrigerant cools down so much that it can again take up environmental heat. 4 / 5

6 Buildings big or small geothermal heat warms them all. The ground stores energy for you Just below the surface of the ground there is enough heat for your home: solar energy that is stored by the ground. With one of Vaillant s ground source heat pumps, you can use this heat just under the surface very efficiently for heating and domestic water preparation, not just in new builds, but also in modernisations: the maximum flow temperature of 62 C makes possible the troublefree use of renewa ble energy in renovated old buildings. Your installer can tell you whether you are eligible for state funding for this sustainable use of energy. The energy source is your home s own plot of land To tap your own ground heat source, you require either a geothermal probe or a horizontal ground collector. For geothermal probes, all borehole depths regarding local regulations can be provided with the use of single or double U-pipes inside. The geothermal probe requires very little space and is very efficient. A ground collector is installed 20 cm below the frost limit. This is approximately 1,20 to 1,50 m beneath the ground s surface. It comprises a plastic pipe that is arranged in curves and loops, similar to an underfloor heating system. A ground collector is cheaper than a geothermal probe but requires a lot of space that cannot then be built upon.

7 Ground source heat pumps Which heat pump do I need? At Vaillant, we have the correct ground heat pump for every requirement, with many different outputs to choose form to ensure your comfort. For example, you can cool your house passive using a heat pump. The automatic cooling function uses the lower temperature of the ground and cools the the living space via the underfloor heating system without costs for the compressor. The heat pump with comfort on demand The heat pump geotherm plus also heats a single-occupancy house using ground heat and what else it does depends on your preferences: either it supplies you with hot water the whole year round, or it provides pleasant passivecooling in the suer. The successor of the winner in the German consumer association product test, the geotherm plus operates with the highest efficiency. The heat pump that can do everything The heat pump geotherm exclusive is the complete solution for a single-occupancy house. It extracts energy using a geothermal probe or a ground collector and supplies heat in the winter, passive cooling in the suer plus hot water at all times. There is an integrated hot water cylinder, likewise an auxiliary electric heater and a weather-compensating controller. The heat pump that remains flexible The heat pump geotherm is characterised by multiple possible applications and the ease with which it can be combined with other systems. The output range from 6 to 17 kw supplies single and dual-occupancy houses, while geotherms from 22 kw are the correct choice for multi-family houses, coercial properties and other buildings with up to 400 m 2 floor space. All can be expanded with a suitable hot water cylinder to match your requirements. Vaillant brine/water heat pumps: German engineering For single to multi-family houses, new builds and modernisations geotherm exclusive with integrated 175 l stainless steel hot water cylinder and natural cooling function 6, 8 and 10 kw geotherm plus with hot water cylinder or cooling function: 6, 8 and 10 kw geotherm heating heat pump: 6, 8, 10, 14 and 17 kw geotherm for larger properties: 22, 30, 38 and 46 kw; cascades up to 92 kw possible Up to 17 kw with auxiliary 6 kw electrical heater Weather-compensating energy balance controller with graphical display of the environmental output Can be combined with a ventilation system The heat pump geotherm exclusive has been awarded the red dot design award. geotherm exclusive 6 / 7

8 Domestic hot water preparation with heat pumps The natural way to wash, shower and bathe: hot water from environmental energy A solar hot water cylinder for heat pumps If you want to combine a heat pump without an integrated cylinder with a solar system for hot water preparation, then the best solution is the new solar hot water cylinder for heat pumps, geostor VIH RW 400 B, because it stores the heat from the heat pump and the solar system in equal measure. If there is sufficient solar output in suer, the heat pump can even remain switched off; the solar system takes over hot water preparation by itself. Two powerful hot water generators The double jacket tank geostor VDH 300/2 is both technically and visually a perfect partner for Vaillant heat pumps without an integrated hot water cylinder. Its double-jacket storage technology ensures convenient hot water preparation. The conventional round cylinder, geostor VIH RW 300, on the other hand, is the right option for you if you are looking for an economic purchase. Solar hot water cylinder for heat pumps geostor VIH RW 400 B Bivalent storage technology for use of the energy from the heat pump and solar system Can be combined with geotherm heat pumps up to 17 (22) kw 3,2 m 2 heat exchanger surface for HP use Magnesium protection anode 1,4 m 2 heat exchanger surface for solare use Hot water cylinder geostor VDH 300/2: Completely stainless steel hot water cylinder Quick heating of large water quantities thanks to double jacket cylinder technology Magnesium protection anode Hot water cylinder geostor VIH RW 300: Specially designed for heat pumps Corrosion protection through use of internal enamelling and magnesium protection anode
