The various output classes up to 19 kW and the high flow temperature (up to 65 °C) predestine the modern Roth ThermoTerra brine-to-water heat pumps for use in new construction and modernisation for single- to multi-family homes.
With their very good performance values, they are designed for monovalent operation. Nevertheless, a 9 kW heating rod is installed as standard for safety and for the anti-legionella function in domestic hot water heating. All types of the ThermoTerra series are equipped with a special energy efficiency heating circulation pump and brine circulation pump with energy efficiency class A, in order to minimise the power consumption of the entire system here as well.
All brine/water heat pumps have integrated heat quantity measurement.
Roth ThermoTerra brine-to-water heat pumps not only impress with their top performance figures (in some cases greater than 5), but also with their compact design. The extremely quiet operation is particularly noteworthy.
All the necessary components for comfortable and environmentally friendly heating, and optionally cooling, are housed in a space-saving manner in an attractive casing. They no longer have to be elaborately mounted on the wall. All components are factory-tested and optimally matched to each other.
Thanks to their compact design, Roth brine/water heat pumps offer planning reliability and extremely simple installation. This saves valuable planning and installation time.
Top performance values
Outstanding performance values - COP (coefficient of performance) - characterise Roth ThermoTerra brine-to-water heat pumps, for example a COP of 5.05 at 12 kW heating output (B0/W35 - EN14511) for the Roth ThermoTerra 12 kW. All units in the series are marked with the energy efficiency label A++ label.
Cooling with the heater
As an option, Roth ThermoTerra brine-to-water heat pumps can not only heat but also cool. An external cooling package (accessory) is required for this. In this case, heat is extracted from the rooms via the radiant heating and cooling systems in the wall, ceiling and floor areas and supplied to the ground. Since this cooling function is covered exclusively by the ground collector or the ground probe, it is referred to as passive cooling mode. The priority circuit for domestic hot water preparation ensures that, if necessary, passive cooling is switched off and the heat pump is switched on until the domestic hot water has warmed up to the desired temperature. Once the set temperature is reached, the system switches back to passive cooling. Since only the circulation pump operates for this purpose and the heat pump remains switched off, this convenient additional comfort is essentially available free of charge. In summer, the temperature of the ground is thus simply used to cool the rooms pleasantly.
