ROBUR STRATEGY ON THE HEATING AND COOLING MARKET
HEAT PUMPS MARKET IS GROWING FAST • Heat pumps are energy efficient • A significant part of the energy is recovered from renewable sources like the geothermal heat or heat from the external air • Heat pumps can be advantageously coupled with low temperature distribution systems • Reversible heat pumps can also provide summer cooling • The investment cost is quickly paid back by savings on energy bills • Heat pumps increase the estate value, thanks to higher Energy Certification ranking
…BUT • Heat pumps consume a lot of electrical energy and often need to increase the electrical power capacity of the building • Air heat pumps have very low heating performance when outside temperature drops, which means when you need it more! It is often necessary to install back-up boilers or resistors • Geothermal heat pumps imply a very high cost for geothermal probes • Most of electrical heat pumps cannot provide Domestic Hot Water • Most of electrical heat pumps cannot produce hot water higher than 55°C, which means they cannot be used to refurbish existing buildings with traditional distribution systems (radiators) ROBUR has the solution: GAS ABSORPTION HEAT PUMPS
ROBUR GAS ABSORPTION TECHNOLOGY • WATER-AMMONIA ABSORPTION CYCLE RECOVERING HEAT FROM OUTSIDE AIR AS LOW AS -20° AND/OR COOLING WITH EXTERNAL AIR UP TO +45° • DIRECT PRIMARY ENERGY INPUT THROUGH PRE-MIXED MULTIGAS BURNERS – NATURAL GAS / GPL • EXTREMELY LOW ELECTRICAL POWER CONSUMPTION (LESS THAN 0,9 kW FOR 35kW OF HEATING OUTPUT)
