I dunno what an Espar block heater is, but a normal block heater installs in about 5 minutes and it two bolts. It does require draining the antifreeze however.

No, that won't work. And if it does then it was luck.
The question no one has asked or stated yet however, is what fuel are these vehicles using? My bet is diesel, and you're using diesel #2. The fuel has probably turned to gel in the cold.
Use a fuel additive, winter blend diesel #2, diesel #1 or stay out of the cold.
Make sure the glow plug light is on before trying to start your van.
Finally, if your vans are not diesel, reply back and let us know and we can point out more things to look at.
