Heat Pump System

Welcome Estía to your home!
Air-to-water Heat Pump System

World-leading energy efficiency –– COP of 4.77*

Comfortable heating and hot water supply

Versatile installation and operation

Introducing Toshiba’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 Toshiba’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.

1.INTRODUCTION

Advantages

World-leading energy efficiency - COP of 4.77*

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

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.

combined with the existing heating system to cover exclusively
and in an optimized way all the heating needs, all year round.
Then, the boiler is only used as a back-up source during some
extreme weather days of the winter.

3-way mixing valve connection

Required Actuator Specification

Electrical Specification:230 V; 50 Hz; <100 mA
The 3-way mixing valve is used to achieve the temperature differential needed in a 2-zone heating system.

• Connect the 3-way mixing valve to terminals 2, 3 and 4 on Terminal Block 04 (for Type 1 mixing valve) or on
terminals 1, 2 and 3 on Terminal Block 04 (for Type 2 mixing valve).

• Connect the 3-way mixing valve in accordance with the diagrams below:-
