New patent recirculation heat pump technology make new era in heat pump field.

Normal air to water heat pump need a huge water tank to accumulate the hot water. After the heat pump make the hot water, they need to keep the water temp with coils and electric heater inside water tank. Acutally this make big energy loss and low efficiency. Our patent recirculation heat pump technology is originally from our Spain shareholder. With smart design, it enable us to use slim water tank without any coils or electric heater inside. The water tank temp is reserved always by heat pumps. Before the DHW go out for shower, it will go through the heat pump plate heat exchanger first. This will increase the water tank about 5-7 centigrade. During the shower, 1/3 of hot water go out for shower, 2/3 of hot water will go to the DHW water tank again. This technology will make the water tank temp drop very slowly and make user feel comfortable. It can also save big room space for end user. From this point, our recirculation heat pump is the real heat pump. The whole system efficiency is much more improved than coil water tank system.
