Toshiba’s new ESTÍA monobloc air-to-water heat pump enables ultra-fast installation on site, and delivers best-in-class heating performance in low ambient air temperatures down to -20ºC. Toshiba Carrier UK Ltd (TCUK) is a joint venture between Toshiba and Carrier in the United Kingdom, and is a part of Carrier, a leading global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies.
As part of Toshiba’s pioneering ESTÍA range, the new monobloc heat pump contains all hydraulic components within a compact, self-contained outdoor enclosure. It requires no refrigerant pipework connections, and can be quickly and easily installed by non-F-Gas registered technicians, reducing time on site and cutting installation costs.
Available in two models, 17kW and 21kW, it provides direct production of domestic sanitary hot water at up to 60ºC, heating in outdoor temperatures as low as -20ºC and cooling in the warmer summer months.
The unit is ideal for large heating and cooling applications, and can control up to four connected ESTÍA units. The supplied large-screen remote control is designed to be easy and intuitive to use for both installers and end users, and can be configured to measure room air temperature or heating system water temperature. It is compatible with all standard communication protocols such as JBUS and MODBUS.
Installers can choose a setpoint for constant hot water temperature, or, for optimum energy efficiency, use the built-in heating auto-curve control to automatically set the target hot water temperature based on outdoor ambient conditions. This latter function can deliver further energy savings and cut power bills for end users, subject to variable hot water temperatures.
Better temperature control is the result of a wider range of compressor frequencies, thanks to Toshiba’s latest inverter drive system, which is based on a new vector-controlled Intelligent Power Drive Unit (IPDU).
The unit’s overall performance is rated at A+ energy class in space heating, with a seasonal part-load heating efficiency of up to 144%.
