Heating element for Redwood Incubator

post #1 of 5
Thread Starter 

 

Sorry for all the pictures but they each are part of my question.  I recently purchased this 1950's Leahy Favorite Redwood Incubator Model 1650 E.  Everything seems to be in working order but it being as old as it is I am going to rewire and replace the thermostat and heating elements.  Its hard to see in the last picture but the incubator has three heating elements each of which are tied together.  The question is twofold:

1.  The incubator badge says that the incubator is 445Watts and the heating element box says on the top 350 Watts.  In changing out the heating elements which number do I go by. Research I have done on this model through the old internet is slim at best but I have been able to determine that the model 1200 had a heater of 350 Watts with a maximum 425 Watts.  The 2100 model had a heater of 500 Watts with a max of 575 Watts.  My assumption is that the 1650 probably has a heater of 350 watts with a max of 445 watts.  The only catalog I could find for this company had all the models in it but was missing one page and of course it is the page that my model is on.  Any suggestions to this theory would be appreciated.

 

2.  If the wattage for the heater is indeed 350 as the box in the picture states.  What is the wattage of each individual element.  Do they add up to 350?  If so what would I replace it with? (Two 100 watt and a 150) or do each of the three elements have to be 350 Watts.  Please advise.

 

I have found a way to purchase the elements to replace but I need to know what wattage to purchase.  In addition what is the white fiber material that is running through the heating wire.  Is it an insulation.  Should I save it?

 

HELP!!!

The badge wattage of 445 would include everything that draws current, light lights, relays and fans. 350 watts is likely correct for just the heat elements. To verify  the  wattage of the heat elements you would need to isolate each coil and check resistance with Ohm meter . The Ohm reading is converted to amps then watts .  Divide the volts (120) by the ohms, this will give you amps. Multiply the amp by volts (120 ) to get watts.  example 120 divided by 100 ohm = 1.2 amp x 120v = 144 watts.The insulating cord protects the coil from sagging or stretching when heated. I think replacing old elements with a pair of  strip heaters may be a good alternate to coils.

If I replace with heat strips how many would I replace with and how many watts each.  Are they suppossed to add up to 350 watts.

Two elements 175 to 200 watts each.  search  vulcan strip heaters on zoro tools. Sometime you can find them on Ebay. Make sure they are for 120 volts. I copied a picture form website(Heaven Sent Ranch Poultry) as an example of replacement elements. They explain on their website how they have fixed up some old leahys .
