Freeze protection heaters

[ernieekberg@...>]

Harry- on my coach are separate thermostats that the original freeze protection
heaters are plugged into. Those thermostats are still functional.
Bluebird did a major overkill on those heaters by mounting them on an 1/8 inch
steel plate. That unit is then mounted to the wall. Talk about heavy.

Ernie - using Paul's suggestion, you should get approximately half
the heat out of the unit compared to if it was run on its design
voltage of 220V. From a heat output perspective, probably somewhere
around a little less than 2/3rds the heat output of a heater designed
for 115v 15 amp circuit. This is a somewhat educated WAG - if we
knew the amperage they would draw, we could calculate this more
closely. Other issue - if you study the pictures on the web site
("more photos"), you will notice that the heaters are not mounted in
any type of enclosure and as such they are not suitable (not safe due
to exposed electrical connections, lack of thermal protection from
the heating elements to adjacent materials, motor hanging out in
space, etc) for directly mounting behind a cabinet, under a bed, etc -
they MUST be mounted in some kind of metal enclosure and then the
enclosure with the heaters mounted inside mounted where you want
them. Also, there is no thermostat on these units, you will need to
wire in some kind of thermostat either in/on the enclosure you build
for them or a separate thermostat some where in the area you are
using them to to heat, otherwise they will just keep heating until
you disconnect them. Lastly, you may want to put an on/off switch
some where near where they are located. Still a great price for what
they are - but they are not a "drop in"
