Blue coolant in Aqua Hot?

I had to disconnect the hoses to one of my compartment heaters when blue coolant came out.  I haven't yet replaced my coolant and because the reservoir is opaque, I've never seen it.  I'm used to red or green coolant.  Can anyone tell me what kind this is?  Thanks

Sven,

Your heater should have 50% distilled water and 50% engine coolant.  Normally for convenience, the engine coolant you use in your engines.  Which one, which color does not matter.

The tank in the heater with the radiator cap should be lipping full.  The overflow tank should be near the hot line when the burner cycles off at full temp.  The level in the overflow tank should go up and down as the heater warms and cools.
