TOSHIBA ESTIA Air to water Heat Pump System (8 - 16 kW)


Toshiba Estía air to water heat pumps are the ideal solution to increase energy efficiency (COP), using air as a main source of energy. This is an all in one system designed to deliver the right temperature for space heating, for domestic sanitary hot water and with the additional advantage of offering air conditioning in the warmer seasons.


Toshiba air to water heat pump systems can manage two independent zones. This solution enables the delivery of water to diverse emitters at different temperature levels up to 55 °C. This new technology enables greater
energy savings and the use of the Toshiba high efficiency heat pump units ensure long term reliability. Toshiba engineers in recent years have developed and patented innovative cutting edge solutions and components 
like the twin rotary compressor and the IPDU inverter which has led to the achievement of great energy savings and high efficiency.


TOSHIBA ESTIA Outdoor unit

Toshiba has a long term experience of successes in air to air heat pump production. The same reliable and award winning technology is at the core of the new air to water heat pumps. Above all the advanced inverter technology and the DC twin rotary compressor. Estía heat pumps operate with the reliable and safe R-410A refrigerant.



The high efficiency plate heat exchanger receives the optimum quantity of refrigerant to produce hot water at low or medium temperature (20-55 °C), or cold water (10-20 °C). A back-up heater (3, 6 or 9 kW options) further supports the operation for extreme conditions. The hydro unit integrates the advanced control of water
temperature to allow an optimized distribution to emitters and to the domestic hot water tank.


TOSHIBA ESTIA Domestic hot water tank

The Estía tank is a compact stainless steel insulated tank producing domestic hot water for sanitary use. The performance of the overall system is also maximized thanks to the integrated coaxial heat exchanger which uses hot water produced by the heat pump (whenever energy efficient and possible). With the optimized control logic, whenever additional hot water is needed, an internal electrical heater is activated. This solution reduces running cost and guarantees a constant level hot water temperature. Three storage capacities (150, 210 or 300 litres) meet any household requirements.


TOSHIBA ESTIA Controller with weekly timer

It controls the distribution of hot water for up to 2 zones and to the domestic hot water tank.The built in software logic collects the signals from the sensors, regulates the water temperature and optimizes the system’s energy consumption. In addition the anti-bacteria control routinely increases the temperature in the domestic hot water tank. The easy to use remote control is conveniently attached to the hydronic unit. With its large and
detailed display it is possible to visualize and set all the major operating parameters and also program the weekly timer.




World-leading energy efficiency - COP of 4.88 (11kW model)

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 saving has a positive impact on the personal electricity bill and the whole community by reducing the CO₂ emissions in the atmosphere


Easy to install

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.


One system, multiple solutions

Estía heat pump systems can be used in combination with different types of emitters: existing heating low temperature radiators, floor heating or fan coil units.


The right temperature at the right time

It can produce water at different temperatures for 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.






Heat pumps - heat from nature


Heat pumps are the first choice for those who want to lower their heating bills and generate heat in a more environmentally responsible way. After all, the environment provides the heat pump with an unlimited and free supply of the energy it needs. This fully-fledged heating system needs very little power for its drives and pumps in order to make this energy available. A heat pump makes you independent of fossil fuels, and in addition, actively contributes towards reducing CO2 emissions and protecting the climate.


Simple principle, great result


A heat pump works in a similar way to a fridge – simply the other way round.

In a fridge, heat is transferred from the inside to the outside. With a heat pump, this happens exactly the other way round. Heat from the air or the ground is transferred into the living space via the heating system. Vapour from a refrigerant is compressed to increase the temperature, to make it high enough for central heating and DHW heating.


Renewable energy from ambient heat


Heat pumps use ambient heat from the water, ground or air. This ambient heat is stored solar energy or geothermal heat from below ground. Ambient heat is therefore a renewable energy, of which we have an inexhaustible supply.
Unlike fossil fuels, renewable energies have the big advantage of being able to be regenerated. In addition, ambient heat is a decentralised energy supply, which is available at all times and which can be used without the need for complex supply systems or energy monostructures.


Use with various energy sources


The best heat source for each individual case depends on local conditions and the actual heat demand. Heat pumps can use various energy sources:

  • Air – practically unlimited availability; lowest investment costs
  • Ground – via geothermal collector, geothermal probe or ice store; very efficient
  • Water – extremely efficient; observe water quality and quantity
  • Waste heat – subject to availability, volume and temperature level of the waste heat


Advantages of heat pumps


60 to 75% lower heating costs

Heat pumps obtain 3/4 of required energy free of any charge, from the environment in which you live. Soil, groundwater, and outside air store huge amounts of thermal energy which can be transformed into heating energy using heat pumps. The savings are considerable compared to other conventional heating systems. The amount of power consumed by heat pumps is notably lower than the amount of heat they generate.


Smart future investment

If you decide to install a heat pump today, you should be aware you are making an investment for the future. Its true value lies in many measurable and nonmeasurable aspects. In addition to the safety of investment, flexibility, low heating costs, comfort, and many economic and ecological benefits, a heat pump is actually an investment in your future and the future of your children.


New building, refurbishment, or heating system replacement

A heat pump is an ideal solution for heating and cooling of newly constructed or refurbished buildings, or when replacing an existing heating system. Since it operates on the principles of low-temperature heating, it is suitable for both underfloor heating and heating with wall-mounted radiators, as well as a combination of both. Heat pumps are also appropriate for rebuilt or refurbished buildings with radiator heating since new high temperature heat pumps can reach water temperatures of 80°C.


Warm in the winter, cool in the summer

Unique heat pump technology allows your heating system to heat your home during the winter and cool it during the summer without additional work or investment. The heat pump system can be used for cooling regardless of whether you use fan coils or underfloor heating.
