Toshiba Launch Estia Air to Water Heat Pump System

Monday, June 21st, 2010

Toshiba has long term experience of successes in air to air heat pump production. The same reliable award winning technology is at the core of the new air to water heat pumps. Above all the advanced inverter technology and the DC twin rotary compressor. Estia heat pumps operate with the reliable and safe R410A refrigerant.

The high efficiency plate heat exchanger receives the optimum quantity of refrigerant to produce hot water at low or medium temperature (20-55’C), or cold water (10-20’C). A back-up heater (3,6 or 9kW) futher supports the operation for extreme conditions. The hydro unit integrates the advanced control of water temperature to allow an optimized distribution to emitters and to the domestic hot water tank.

The Estia tank is a compact stainless steel insulated tank producing domestic hot water for sanitary use. The performance of the overall system is also maximised thanks to the integrated coaxial heat exchanger which uses hot water produced by the heat pump (whenever energy efficient and possible). With the optimised control logic, whenever additional hot water is needed, an internal electric heater is activated. This solution reduces running cost and guarantees a constant level of hot water temperature. Three storage capacities (150, 210 or 300 litres) meet any household requirements.

The system includes a weekly timer that controls the distribution of hot water up to 2 zones and to the hot water tank. The built in software logic collects the signals from the sensors, regulates the water temperature and optimizes the systems energy consumption. In addition the anti-bacteria control routinely increases the temperature in the domestic hot water tank. The easy to use remote control is conveniently attached to the hydronic unit. With its large and detailed display it is possible to visualize and set all the major operating parameters and also program the weekly timer.

The Toshiba Estia has a COP of up to 4.66.
