HITACHI RWLT-3.0VN1E Low Temperature Hydraulic Module
HYDRO FREE units produce heating and domestic hot water like any oil or gas boiler, but transforming renewable energy from the outside air into heat. Air to water heat pumps extract the free energy present in the air, which is enough to heat a home up to a comfortable temperature, even on the coldest winter day. Every kW of electricity used to power the heat pump can yield up to more than 5 kW of energy for heating; this provides savings of up to 80% on heating expenses compared to a traditional fossil fuel boiler. The new HYDRO FREE series, based on state-of-the-art technology, does not only achieve an outstanding performance in space heating, but it is also provides domestic hot water with high efficiency. Additionally, cooling operation for summer can also be provided installing the dedicated “Cooling kit” accessory of HITACHI (Depending on the model). The system is simple to control; its new user controller (PC-ARFWE) improves the acclaimed and successful design used with the existing LCD controller, and provides a great deal of new functions like: wizard start-up configuration, auto cool/heat, improved timer, etc.
HITACHI RWLT-3.0VN1E Low Temperature Hydraulic Module consists of one outdoor unit and one indoor unit. The outdoor unit extracts the heat present in the air, increases its refrigerant temperature and transmits it to the water circuit using the plate heat exchanger of the indoor unit, where the heat is taken to radiators (fan-coils), underfloor heating components or both (2nd temperature area). Three types of indoor unit can be used in heating split systems: This HYDRO FREE indoor unit is designed for space heating, in wall-mounted installation. It is convenient for new installations with low capacity requirements (Well isolated installations, high efficiency radiators…).
