Q.		Do the coolant heaters fit within the definition of APU? Example Webasto’s Thermo 50, DBW 2010 etc.

No, an APU gives you 3 things, the ability via a generator to give you heat, air-conditioning and power. The units you mention above heat coolant, these are diesel fired coolant heaters not generators. They can bring engines up to temperature and additionally via a heat exchanger provide heat to interiors. The are much smaller the APU's and easier to install.
