The new EST√ćA monobloc air-to-water heat pump from Toshiba
​​Toshiba says its new ESTÍA monobloc air-to-water heat pump offers simple installation and best-in-class heating performance in low ambient air temperatures down to -20degC.
All hydraulic components are contained within a compact outdoor enclosure. It requires no refrigerant pipework connections, and the manufacturer says it can be quickly and easily installed by non-F-Gas registered technicians.
Available in two models, 17kW and 21kW, it provides direct production of domestic sanitary hot water at up to 60degC, heating in outdoor temperatures as low as -20degC and cooling in the warmer summer months.
The unit is designed for large heating and cooling applications and can control up to four connected ESTÍA indoor 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 is said to deliver further energy savings and cut power bills, subject to variable hot water temperatures.
Overall performance is rated at A+ energy class in space heating, with a seasonal part-load heating efficiency of up to 144%.
