Toshiba Highlights Latest Generation of ESTÍA Heat Pumps in New Brochure
The latest generation of Toshiba’s ESTÍA heat pump, ESTÍA 5, is now available and being highlighted in a new brochure. After 10 years of continuous research and development in air-to-water heat pump technology, the new series of ESTÍA heat pumps delivers energy efficient, low cost heating and cooling for homes and small commercial properties. Toshiba Air Conditioning UK is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).
The ESTÍA range delivers best-in-class Coefficient of Performance (COP) of 4.90 at an air temperature of +7°C and 3.01 at -7°C, setting a new bench mark for heat pumps of this type. It is available as a split system from 4 to 16kW and monobloc from 16 to 21kW and has an efficiency rating of A++ for space and combination heating.
It can replace or complement conventional gas boilers and will work with all types of heat emitters, delivering hot water temperatures up to 55°C. It is based on Toshiba´s pioneering twin-rotary compressor and Intelligent Power Drive Unit (IPDU) inverter technology, which precisely maintains heating and cooling capacity with high energy efficiency at all times, especially at part load use.
It offers outstanding performance even at very low ambient temperatures, providing heating at outside temperatures down to -25°C, and domestic hot water from +40°C to +75°C. Part load efficiency, at up to 163%, exceeds the latest European Commission Key Performance Indicator.
The system comprises an outdoor unit, hydro module and water tank, making installation straightforward with no need for flue or groundworks. The split solution can also work alongside traditional boilers as part of hybrid systems designed to optimise energy use.
All types of heating and cooling emitters can be used with ESTÍA, including existing low temperature radiators, underfloor heating systems and fan coil units. Similarly with temperature control, traditional or new generation thermostats – including PC and smartphone applications – all interface seamlessly.
For larger installations and those requiring higher water temperatures, the ESTÍA monobloc is rated A+ for space heating, and also has a best-in-class COP of 4.10 at an air temperature of +7°C and 2.51 at -7°C. The system provides direct hot water production up to 60°C down to an outdoor temperature of -10°C, and heating at outdoor temperatures down to -20°C. Part load efficiency is up to 144%.
