You may be asking "What is Webasto?"  Webasto is the most advanced temperature control heating system for coaches.  The purpose of supplemental heat is to eliminate the need to run your engine and/or generator on a continuous basis.  That is where a Webasto unit comes in.  It provides engine preheat, supplemental interior heat, maintains optimal engine operating temperature and accelerates window defrosting and defogging.  In addition, major custom coach manufacturers are using these units in conjunction with the water supply to maintain instant hot water.
 
Some of a Webasto's features include: variable temperature  control, nozzle burner system which provides instant heat and low maintainence, a heavy-duty modular design which is based on market experience and customer requirements.  An electronic ignition systm ensures reliable starts and low power consumption.  Its compact size makes it the lightest and smallest heater in its class.  It is integrated into your fuel and electrical system so there is no need for supplemental fuel sources or batteries. 
 
With a many unit types available with varying BTU ratings, there is an ideal unit to fit your personal needs.  All new units come with a full factory  2 year warranty.
