Estía — Toshiba’s advanced air-to-water heat pump solution — uses patented innovative technologies that take advantage of renewable energy of its surroundings to heat water for usage as residential space heating and as a hot water supply. Estía is suited for both new homes as well as renovations. Estía replaces or compliments traditional boilers used for heated floors, space heating radiators as well as hot water supply for domestic use. An advanced heating and cooling system of the future, Estía reduces running cost while contributing to reduction of CO2 emissions by using renewable energy.
WORLD-LEADING ENERGY EFFICIENCY-COP OF 4.88*
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 saving 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.

Toshiba advanced technology
Toshiba Inverter uses the new, vector controlled, Intelligent Power Drive Unit, which enables a wider range of frequencies and voltages. The Toshiba DC Twin Rotary Compressor has a large capacity range operation, with an effective system of power limitation, which reduces the power consumption.Performance is further improved by the high-speed converter circuit which calculates and optimizes the power supply to the compressor.
The use of ToshibaEstía heat pump contribute to the reduction of global CO2 emissions in the atmosphere and limit the use of fossil fuels or 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.
ONE SYSTEM, MULTIPLE SOLUTIONS
Estía heat pump system can be used in combination with different types of emitters: existing heating low temperature radiators, floor heating or fan coil units.
Toshiba has 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 hear pumps. Above all the advanced inverter technology and the DC twin rotary compressor.
11kW, 14kW, 16kW
The high efficiency plate heat exchanger receives the optimum quantity of refrigerant to produce hot water at low or medium temperature, or cold water. A back up heater (3,6 or 9kW 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 hot water tank.
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 liters) meet any household requirements.
CONTROLLER WITH WEEKLY TIMER
It controls the distribution of hot water for up to 2 zones and to the 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 hot water tank. The easy-to-use remote control is conveniently attached to the hydro 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.
POWERFUL TYPE (8kW-11kW)
FOR COLD CLIMATE AREAS AND HIGHER WATER TEMPERATURE NEEDS
- Leaving water temperature 60℃ is achievable down to -5℃ *1
- Expanded operation outdoor temperature down to -25℃ *2
- Maintain the rated capacity down to -15℃
- *1 The water temperature might not reach to 60℃ depending on the contribution such as the low water flow.
- *2 As it is possible that the system does not start at -25℃ ambient, the main power supply should be turned on prior to start of operation.
