HVAC AmbiRad displayed the genuine energy saving benefi ts of this method and its heating systems with an example at RAF Brize Norton’s Base Hangar. The station energy manager fi rst contacted AmbiRad in 2004 to discuss the ineffi cient and unsustainable heating system that was in place at the time. From 2004 to 2012 the cost of gas to heat the hangar had risen from £400k to £800k per year. Following an investigation into the options, taking into account whole life costing, AmbiRad’s radiant tube heating was found to be the best solution for long term value. Economy and effectiveness are the two key factors when selecting a heating system for an aircraft hangar. The hangar environment is too hostile for some forms of heating. Warm air heating, for example, would not be an appropriate solution. The system would consume fuel attempting to heat the entire volume of air in the hangar and the temperature stratifi cation would be enormous. This volume of air would then only be replaced instantly with colder external air when the doors are open to allow aircraft movement in and out, bearing in mind that many aircraft maintenance operations occur at night. Radiant tube heating answers all of these needs. It burns fuel (natural gas or LPG) at the point of use so there is no loss of effi ciency in distributing heat around the building. Most importantly, in the case SPECIAL FEATURE ‘In specifying a heating system, it is important to base requirements on output and functional needs.’ of aircraft hangars, the warmth from the radiant system felt by personnel is less affected by cold air infl ux through doors opening and closing, but also the ability of the heating system to rapidly respond to changed conditions is paramount. After just a few months of instalment, energy consumption in the hangar was found to have reduced dramatically. The result, a potential saving of 75 per cent over the previous warm air system. This is something that every sector can benefi t from and with forward thinking companies strongly backing the system, there can be nationwide savings of up to millions of pounds. With the uncertainty of future energy costs, it is a saving that no one can afford not to make. Economy and effectiveness are the two key factors when selecting a heating system for an aircraft hangar.
