Block heater vs booster heater vs auxilary heater vs Espar?
Please unconfuse me.
Please unconfuse me.
I’m not sure not sure we are on the same page yet. The rear heater is not directly attached to the Espar. It is plumbed into the cooling system with the other cabin heater.Ok, thanks Patrick. So my Espar is not working...and looking underneath the left front there is no hose connecting it to the heater muffler. However, the booster does blow out more warm air while the engine is running. So that would confirm that the Espar is still, well....working...but there is another reason it isn't blowing its own air?
If you only have the HZ9, you probably only have the Booster."H12 HOT WATER ADDITIONAL HEATER <-- Espar used with 7-day timer"
I do not have this code but do have an Espar. Is there a code for Hot Water Heater WITHOUT 7-day timer?
I only have HZ9, heater booster code.
OK so far... but then:The "booster heater" = Espar that initiates the booster function.
No!Auxiliary heater as referenced in the manual indicates an optional additional heater (not the Espar)
... it's the "engine shut off" part that separates the "booster" from the "auxiliary".used with a timer and rocker switch and is used when the engine is shut off.
One of the functions of the auxiliary heater is also to pre-heat the engine.The block heater is the wire attachement to the block that you plug in to an outlet to preheat the engine to aid in cold starting.
Have I missed anything?
correct
So I have the Espar which creates the heater booster function
It's an either/or: IF you have the Aux Heater option THEN you EITHER have the Aux switch OR the clock.but my Espar doesn't have the auxiliary heater option because I do not have the timer/rocker switch combo?
