In line with the increasing focus on heat pumps as a new heat source, in July 2009 Toshiba Carrier unveiled the Estia, its new environmentally-oriented air to water heat pump system for European markets that adopts a combination of Toshiba’s heat pump and inverter technologies of the highest global standard.
Incorporating Toshiba’s most advanced technology in all components from the compressor and inverter to the refrigerant, the system has already been launched in Europe. The outdoor unit of the highly efficient light commercial air conditioner the Super Digital Inverter forms its base.
Almost all residential heating in the UK, France, Germany and Sweden is done using heated water in radiators, floor heating systems and fan coils, although the proportion of various heat sources, such as oil and gas boilers, electric heaters and heat pumps, differs by country. Estia provides welcomed flexibility in connecting to these existing heat sources. The hot water heated by the heat pump can be sent to a panel radiator or fan coil to heat a room, or circulated in hot water pipes in floors to provide radiant floor heating in winter. Hot water can also be supplied to a shower or kitchen through hot water pipes from the hot water tank (150, 210, or 300 liters).
Estia comes in a lineup of 3, 4, and 5 hp models. The 4 hp model boasts the world’s class of energy efficiency with a COP of 4.66.
