2 KEMPER ThermoSystem Drinking Water heating without compromise The KEMPER KTS ThermoSystem combines fulfilment of the highest domestic hot water-hygiene requirements, energy optimisation, convenience and comfort as well as security of supply at all draw-off points. KTS is a modern, central domestic hot water heating system, which operates according to the continuous flow principle. The constant discharge temperature at the draw-off points is achieved in particular due to the high control quality of control unit integrated in the ThermoBox. Use of KTS enables integrated design and installation of a hygienically safe and energy-optimised drinking water heating system in the familiar KEMPER quality. This includes not only the connected domestic hot water system but also the circulation system (PWH and PWH-C). KTS makes energy efficiency + domestic hot water hygiene systematic! Advantages at a glance No domestic hot water hygiene risk areas due to patented cascade rotation Energy-efficient operation Low investment costs due to precise, customized system design Fast presence and high consistency of the outlet temperature (PWH) for small and large draw-off quantities Can also be used for aggressive domestic hot water* Low limescale precipitation due to patented positioning of the plate heat exchanger Longer pump life thanks to patented cooling of the pump electronics In-house KTS service team * EPDM sealed version of the ThermoBox 2

3 How it works Intelligent technology acc. EN 806 PWC = potable water cold PWH = potable water hot PWH-C = potable water hot - ciruclation drinking water installation and consumption drinking water heating heat generation and energy storage primary feed heating feed Heat source For example: > Boiler > Heat pump > Solar system > CHP > Solid fuel boiler primary return heating return According to DIN , the KEMPER KTS ThermoSystem is an indirectly heated continuous flow domestic hot water heating system. The thermal energy required for the domestic hot water heating is stored in a buffer tank on the heating side. The domestic hot water is solely heated in flow. If one or several draw-off points for heated domestic hot water are opened, the plate heat exchanger heats the required quantity of domestic hot water. The draw-off flow rate is determined exactly by a flow rate sensor. At the same time different temperatures are measured. The control uses this information to activate the high-efficiency pump, which pumps the heating water out of the buffer tank, the KTS ThermoTank. The KTS ThermoTank S has an internal baffle, which ensures low-turbulence stratification of the return medium from the domestic hot water heater. To use the low return temperature to increase the efficiency optimally, it must be prevented from mixing with warmer layers in the buffer tank. To this end a thermostatically activated 3-way changeover valve is inserted in the return pipe to the buffer tank. Depending on the set temperature, the return water is fed specifically into the bottom or middle area of the buffer tank. Unlike domestic hot water tanks, in which this is questionable from a hygienic point of view, in buffer tanks the formation of temperature stratification is explicitly required from an energy point of view. Recharging of the buffer tank is controlled precisely by two Pt 1000 sensors attached to the buffer tank. The KTS ThermoBox is delivered electrically and hydraulically preassembled. The recharging requirement can be transmitted to the heat generator via a floating contact of the control. The optimised arrangement of the system components makes maintenance easy. Quality is our standard since 1864

4 Cascade arrangement The tailor-made solution for large properties Up to four ThermoBox modules can be connected together to form a cascade to cover the demand of high draw-up flow rates. In this way the PWH demand of small flow rates (e.g. one draw-off point) through to peak flow rates with high simultaneity can be covered. Thanks to the cascade arrangement, high control quality is achieved across the complete bandwidth of the PWH demand and what is more, is always at the energy optimum. Continuous alternation of the modules is achieved by the patented cascade rotation. This ensures uniform capacity utilisation of the individual units at all times. drinking water installation and consumption The necessary communication between the ThermoBox modules takes place via Mod- Bus. Connection to an existing building services management system is possible via the KTS ComLog module, or also via ModBus. The KTS ComLog module can also be used as a data logger for recording the operating parameters. 1 2nd 1st GF BM 4

7 The Technical data -ThermoBox KTS ThermoBox If larger draw-off flow rates are required, up to four units can be connected together as a cascade.

8 The -ThermoTank S optimised "energy storage" for domestic hot water heating The KTS ThermoTank is a heating medium buffer tank, which has been developed with the help of state-of-the-art flow simulation software. This achieves energy-optimised, temperature-dependent stratification during the charging and discharging process of the heat transfer medium. The internal baffles ensure low-turbulence stratification of the return medium from the domestic hot water heater. The unitised construction of the insulation enables retrofitting even in an already completed pipe installation. Hook strips help to ensure easy closure. Subsequent dismantling and renewed refastening is also no problem. The insulation made of rigid non-woven is characterised by its optimised fit and conforms to building material class B1. Thanks to its very low thermal conductivity, energy-efficient storage of the heating medium is possible. The variable heights of the temperature sensors enable the temperature zones to be arranged individually. This in turn enables coordination of the ThermoSystem with the heating system. Among other things, this enables the timing of the heat source to be optimised and temperature zones to be adjusted to different heat source combinations.

10 -ComLog module Safety through monitoring of the system The ComLog module, Model , logs each measured value recorded by the ThermoBox control. The measured values are logged with time and date at a sampling rate of 10 seconds. This enables continuous documentation of operation. The data is stored on an SD card and can be evaluated and visualised using conventional spreadsheet programs. Visualisation of the data (see example below) enables the use behaviour of your property to be displayed and your complete system to be adjusted and optimised. Documentation of the function of the KTS system Interface with the BSMS Data stored in CSV format 1 GB memory card is included in the supply Part No Flow rate [l/min] Temperature [ C] Flow Rate PWH Temperature Primary Feed Temperature Temperature at bottom of Thermo Tank Time [hh/mm] Example: Possible graphic evaluation of a ComLog file for one day 10

11 -Temperature controlled 3-way changeover valve Optimised temperature stratification The temperature-controlled 3-way changeover valve is used to optimise the stratification within the ThermoTank. In this way the different return temperatures of the respective operating situations are taken into account (draw-off or circulation case). The temperatures in the bottom part of the ThermoTank are kept low to enable heat source high efficiency to be achieved. Due to the optimised stratification, mixing of the heating medium is reduced to a minimum. This means a constant high temperature level is achieved in the top part of the ThermoTank. This increases the efficiency of the heat source and the ThermoBox and reduces the ThermoTank volume required compared to other buffer tanks.

12 -Design support Know-how for energy efficiency and security of supply Use-orientation is an important factor in the KTS design! To this end, detailed recorded data of water consumptions and user profiles in medium-sized and large properties are evaluated and used as demand profiles. The demand profiles database is extended continuously. The profiles can be individually adjusted and combined to obtain a realistic representation of user behaviour. The PWH value is calculated target-orientated, independent of the user profile. With the circulation heat demand added, the actual cumulative heat demand required is obtained (PWH + PWH-C). Precisely matched to the determined demand, the KEMPER KTS ThermoSystem can be designed to be energy-optimised. The heat supply required is available at all times.
