        Air Conditioning Heating and cooling
        Most air conditioning systems these days 
        are heat-pumps which means they heat and cool. This has been made more 
        effective with R410a gas which has a higher pressure and the correct 
        heating properties thus producing more heat. Heat-pump air conditioning 
        these day produce astonishing efficiently with some air conditioning 
        manufactures producing 6x input, usually called COP  Technically 
        the air conditioning unit produces heat by reverse cycle. The condensing 
        unit (outdoor coil) becomes the evaporator taking heat from the outside 
        air and blowing cold air from the coil. The evaporator (inside coil) 
        then takes cold out of the indoor air and blows heat in. Air 
        conditioning heating is by far the most efficient way of heating. Take a 
        look at the cost of each heating system. Air conditioning heating..
        
        
        
        
        Becoming 
        ever more popular the air conditioning heating / air source heat-pump is ideal for space heating 
        areas where existing water systems are in place such as radiators. They 
        work in the same principle as air conditioning and refrigeration but 
        generally the air source heat-pump is used for air to water heat 
        transfer where air conditioning is air to air transfer.
