MTS 150 drinking water storage module
As decentralised hot water preparation, the enamelled drinking water storage module offers a capacity of
149 l of heated domestic water and a smooth-tube heat exchanger with a surface area of 1.8 m
drinking water volume is designed for an average tapping rate of 10l/min. An intelligent heating logic is used
here, which ensures rapid switching on and off when hot water is required with the aid of dual-sensor tech-
nology.
When hot water withdrawal is active (e.g. when taking a shower), the lower probe registers that cold water is
flowing in from the cold water connection. This cools down the lower part of the drinking water in the storage
module. The heat pump then switches the changeover valve and immediately starts the hot water prepara-
tion and the reheating process of the domestic hot water tank. In this case, the warm inlet flow is directed
into the storage module and a warm return flow is generated promptly, as a considerably higher temperature
level is used here. Therefore, one probe is installed in the upper part and one in the lower part of the module
to realise a short reaction time. In this way, the domestic hot water storage module ensures that the domestic
hot water to be tapped is available at the set desired temperature. The 2.9 kW heating capacity of the MWP
35 heat pump module ensures that the MTS 150 is constantly recharged. With the additionally installed 3kW
heating rod (Smart-Serv), a so called "Booster function" can be activated to increase the recharging power or
the temperature in case of higher consumption.
Due to the decentralised hot water preparation and a central positioning (within the residential unit) of the
MWL 35 modular heat pump, the pipe routes to the taps are deliberately so short that one remains below the
3 litre volume within the pipework (from the output of the DHW storage module). This means that you do not
fall under the German Drinking Water Ordinance (see chapter 3 "The German Drinking Water Ordinance in
connection with REMKO heat pumps"). For this reason, there is no need for an additional circulation line,
which - in addition to further installation costs - would result in higher electricity costs and thermal radiation
losses. Furthermore, tapping valves and the annual inspection obligation are no longer required.
