3.2. Connection with thermal store (combination with other heat sources)
The accessories consist of a thermal store for heating only (Regulus PS series), or
a combination thermal store with immersed DHW tank (Regulus DUO series), or a thermal
store with continuous hot water heating in a stainless steel DHW heat exchanger (Regulus
HSK series).
This connection is suitable for combining a heat pump with other heat sources, such as
biomass boilers, fireplace inserts and stoves with a hydronic heat exchanger, solar thermal
systems, solar photovoltaic systems, etc. The thermal store shall be sized depending on the
selected type and output of the heat source. E.g. for a combination with a PV system the total
volume of the thermal store can be calculated using the relationship 180 l / 1 kWp PV output.
For example, for an array of PV panels with a peak output of 5 kWp, the tank volume shall
be 900 litres. Always have the size and type of the thermal store determined by a specialist!
3.3. Heating system with the use of cooling
RTC 13e heat pumps also allow cooling of buildings. If cooling operation is used, all tanks and
chilled water distribution systems must be vapor-insulated. If there are also space heating
elements in the building that are not suitable for cooling (radiators, heated towel rails, etc.), it
is recommended to shut off these circuits to prevent undesired condensation of air humidity.
