Heat Pump System
Introducing To shiba’s super-efficient space heating and hot water supply system for homes and businesses. Estía
represents breakthrough thinking in intelligent heat pump and inverter technologies, by efficiently transferring
ambient thermal heat from outside air to heat water indoors. Based on Toshib a’s proven light commercial air
conditioning system, the Super Digital Inverter, this innovative unit features DC twin rotary compressor, DC
inverter and R410A refrigerant, providing the highest coefficient of performance (COP) in its class. This means
more power from less energy consumption, and the ideal ecological and economical solution for your home.

With its best in class COP performance, Estía air to water heat pump system delivers more heating
power with less energy consumption.
Estía uses high quality components and material which contribute to the overall savings in energy
consumption.
With the Toshiba advanced inverter, Estía air to water heat pump system only delivers the heating
capacity required; thus consuming only the necessary electricity.
The hot water temperature is also optimized thanks to Toshiba advanced control depending on
the outside air temperature. The milder outside, the air-to-water systems automatically produces
lower water temperature to anticipate decreased needs of space heating. The same control logic
allows to anticipate as well increasing heating needs when weather conditions become extreme;
this overall temperature management gives the best conditions of comfort.
All this s
reducing the CO2emissions in the atmosphere.

It can produce water at different temperatures
or several applications simultaneously.
Toshiba Estía air to water heat pump system operates smoothly
both with low outdoor air temperature down to -20 ˚C in winter
and up to 43 ˚C in the summer season. The system has a unique
anti-ice build-up protection embedded.
Quick and easy to install. The hydro module
unit can be placed safely in the most suitable
place within the house.
There’s no need for chimney or underground
captors which require additional works on site.
The compact outdoor unit can be placed anywhere outside the
house or on a balcony, thanks to extensive piping options.

other non-renewable energy primary sources.
Whenever required for maintenance purpose,
all the R410A refrigerant (non ozone depleting) can be
completely sucked back to the outdoor unit through the
powerful embedded Toshiba “pump down” operation.
