Efficiency: A+++ with R32 Refrigerant
The innovative ESTÍA R32 range meets the growing demand for alternatives to conventional heating solutions. Driven by increased climate emergency awareness and attractive government incentives, this advanced air-to-water heat pump significantly reduces energy bills compared to gas boilers and electric heaters. It offers impressive capacity specifications for both heating and hot water production.
Comfort: 65°C Hot Water All Year Round
Featuring latest-generation liquid injection technology, the new TOSHIBA Twin Rotary compressor enables ESTÍA R32 to supply water to heating circuits at temperatures that ensure comfort throughout the year. This is true even in exceptionally cold periods (water outlet temperature of 65°C for 8 and 11kW models).
For maximum well-being, ESTÍA R32 also produces domestic hot water even at exceptionally high outdoor temperatures (+43°C) using only compressor operation. An integrated 3 kW backup heater ensures additional heating and domestic hot water supply when needed.
Silence: As Low as 32dB(A)
ESTÍA R32 operates in silent mode at just 32dB(A) (for the 4kW model at 5m from the outdoor unit in open field 2). This is comparable to the quiet hum of a refrigerator, significantly quieter than a truck, a club, or an airplane.
- Refrigerator: 0 dB
- ESTÍA R32 (Silent Mode): 32 dB
- Truck: 80 dB
- Club: 110 dB
- Airplane: 140 dB
Your Style, Your Rules: Adaptable Design
With a timeless design, ESTÍA adapts to any type of emitter, providing flexible heating and cooling solutions for your home.
Compatible Emitters:
- Underfloor Heating: Efficiently distributes warmth throughout your space.
- Low or Medium Temperature Radiators: Integrates seamlessly with existing radiator systems.
- Fan Coils: Offers both cooling and heating functionalities.
The system also provides domestic hot water production. The outdoor unit (ESTÍA) connects to the indoor unit (ESTÍA AIO) via R32 refrigerant lines, distributing heated or cooled water to various emitters within the home.
Take Control of Your Home
The ESTÍA R32 remote control covers one or two zones, allowing intuitive management of functions like silent mode, energy consumption visualization, and programming. The self-adaptive function provides optimal comfort relative to outdoor temperature, helping to minimize energy bills. The unit control can be configured in 16 different languages.
Smart Home Integration:
- Energy Monitoring: Track your energy consumption directly from the display.
- Voice Control Compatibility: Works with smart speakers and voice control via Google Home Assistant and Amazon Alexa.
With the ESTÍA R32 wireless interface and the Toshiba Home AC Control app (available on App Store and Google Play), you have comfort always at your fingertips. The system connects wirelessly to a router, allowing remote management of the ESTÍA AIO unit.
