Toshiba has introduced a new Monobloc air-to-water heat pump

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 minus 20degC.
As part of Toshiba’spioneering ESTÍA range, the newmonoblocheat pump contains all hydraulic components within a compact, self-contained outdoor enclosure. It requires no refrigerant pipework connections,andcan 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 60degrees C, heating in outdoor temperatures as low as -20degC and cooling in the warmer summer months. 
The unit is ideal for large heating and cooling applications, and can control up to four connected ESTÍAunits. The supplied large-screen remote controlis designed to be easy and intuitive to use for both installers and end users, andcan be configured to measure room air temperature or heating system water temperature.It is compatible with all standard communication protocols such asJBUS 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 savingsand cut power bills for end users, subject tovariable 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 performanceis rated at A+ energy class in space heating, with a seasonal part-load heating efficiency of up to 144per cent.
