WEBVTT 00:00:02.039 --> 00:00:04.000 The replacement of a cooling machine 00:00:04.000 --> 00:00:06.719 is the opportunity to install a heat pump. 00:00:06.920 --> 00:00:09.840 However, this conversion may be complex: 00:00:10.320 --> 00:00:11.960 heavy hydraulic works, 00:00:12.360 --> 00:00:13.280 high costs, 00:00:13.599 --> 00:00:15.760 and potential low efficiency. 00:00:15.840 --> 00:00:16.519 Why? 00:00:16.519 --> 00:00:17.639 Because heat pumps 00:00:17.639 --> 00:00:20.280 are frequently connected to the original heating system, 00:00:20.280 --> 00:00:21.440 designed at high temperatures, 00:00:21.679 --> 00:00:24.920 while heat pumps are always more efficient at low temperature. 00:00:25.239 --> 00:00:26.079 The result? 00:00:26.079 --> 00:00:27.519 Lower efficiency, 00:00:27.519 --> 00:00:29.880 higher power consumptions 00:00:29.880 --> 00:00:31.159 and shortened service life. 00:00:31.440 --> 00:00:34.079 With the Heat 4T° upgrade kit, this conversion is 00:00:34.079 --> 00:00:36.320 radically simplified and optimized. 00:00:36.480 --> 00:00:38.440 The new heat pump is connected 00:00:38.440 --> 00:00:40.559 exclusively to the chilled water network. 00:00:40.880 --> 00:00:42.639 The Heat 4T° kit is installed 00:00:42.639 --> 00:00:45.400 directly on the thermostats of the terminal units... 00:00:45.760 --> 00:00:47.880 No further changes are required. 00:00:48.119 --> 00:00:49.199 How does it work? 00:00:49.360 --> 00:00:50.599 The Heat 4T° system 00:00:50.599 --> 00:00:52.280 uses the chilled water network 00:00:52.280 --> 00:00:53.519 in a reversible way. 00:00:53.920 --> 00:00:55.599 To do this, it measures the temperature 00:00:55.599 --> 00:00:57.880 of the network and automatically adapts 00:00:57.880 --> 00:01:00.119 the control signals from the thermostats to operate 00:01:00.119 --> 00:01:02.079 the chilled water network all year round: 00:01:02.719 --> 00:01:04.719 for conventional cooling in summer, 00:01:04.920 --> 00:01:08.079 but now also for low-temperature heating in winter. 00:01:08.320 --> 00:01:10.320 By using the chilled water network, 00:01:10.320 --> 00:01:12.760 a flow temperature of 42 °C 00:01:12.760 --> 00:01:14.440 is sufficient to heat the premises, 00:01:14.440 --> 00:01:15.639 even in the middle of winter. 00:01:16.199 --> 00:01:18.159 What if the heat pump breaks down? 00:01:18.159 --> 00:01:20.119 The Heat 4T° automatically switches 00:01:20.119 --> 00:01:23.320 to high-temperature heating via the boilers 00:01:23.440 --> 00:01:24.440 The result ? 00:01:24.559 --> 00:01:26.400 much simplified works, 00:01:26.400 --> 00:01:30.199 gas consumption reduced by 40% to 80% 00:01:30.199 --> 00:01:32.440 and a better used heat pump 00:01:32.440 --> 00:01:33.960 that consumes 30% less. 00:01:34.440 --> 00:01:35.519 More details ?
