KEMPER ThermoSystemDrinking Water heating without compromise

The KEMPER KTS ThermoSystem combines fulfilment of the highest domestic hot wa-ter-hygiene requirements, energy optimisa-tion, 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 ac-cording 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 en-ergy-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).

How it worksIntelligent technology

According to DIN 1988-200, the KEMPER KTS ThermoSystem is an indirectly heated continuous flow domestic hot water heat-ing system. The thermal energy required for the domestic hot water heating is stored in a buffer tank on the heating side. The do-mestic 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 in-formation 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 strat-ification of the return medium from the do-mestic hot water heater. To use the low re-turn temperature to increase the efficiency optimally, it must be prevented from mix-ing 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 questiona-ble from a hygienic point of view, in buffer

tanks the formation of temperature stratifi-cation 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 pre-assembled. The recharging requirement can be transmitted to the heat generator via a floating contact of the control. The opti-mised arrangement of the system compo-nents makes maintenance easy.

Cascade arrangementThe tailor-made solution for large properties

Up to four ThermoBox modules can be con-nected 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 com-plete bandwidth of the PWH demand and what is more, is always at the energy opti-mum. Continuous alternation of the mod-ules is achieved by the patented cascade rotation. This ensures uniform capacity uti-lisation of the individual units at all times.

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

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 dur-ing 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 op-timised fit and conforms to building mate-rial 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 indi-vidually. This in turn enables coordination of the ThermoSystem with the heating sys-tem. 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.

-Temperature controlled 3-way changeover valve Optimised temperature stratification

Circulation mode:In circulation mode the return has a higher temperature level and is fed into the middle area of the ThermoTank.

The temperature-controlled 3-way change-over valve is used to optimise the stratifi-cation 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 min-imum. This means a constant high temper-ature 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.

Supply case:In the supply case the return cools rapidly and is fed into the bottom area of the ThermoTank.

Use-orientation is an important factor in the KTS design! To this end, detailed re-corded data of water consumptions and user profiles in medium-sized and large properties are evaluated and used as de-mand profiles. The demand profiles data-base 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-orien-tated, 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 de-signed to be energy-optimised. The heat supply required is available at all times.
