Here is a picture from the Nordic Sensor website that shows the specs on the sensor you should order from them. drive.google.com/open?id=0B8_jm7K-ahMaZkxqQmJmNmdvS1UGo to this link and it will take you to a "builder" where you can build your own cartridge heater. Put in the specs listed in the photo. Then you will get a quote via email from them. Then just follow the instructions from their emails. Its a little convoluted but they are more geared towards businesses. Let me know if you need help. Cablehack, I like that heater. Very creative! |

I like how my 12 watt heaters are saving me some pennies over everyone else running the 15 watt ones.  $3.60 a year I think? |

Honestly, the only reason I suggested the 15 watt is because I had forgotten that was the wattage I used for my DR. They tend to like a little more heat. A 12 watt heater would do just dandy. Besides, if you order a 12 watt it will be closer to 15 watts in reality anyways. It's all down to the method that Nordic uses to create these heaters. They always run a few watts more than what they are rated for.

One thing to keep in mind is the normal range of mains voltage has an effect on the actual heater power. For example, a 1000 ohm element will dissipate 12W at 110V, but rise to 14.4W at 120V.

Absolutely. I just found it odd that they are rated for 120v and the watt draw is a few higher than advertised. Not a big deal at all. Just odd.

The DRF4 has a much larger heater. They get what they need. I'll eat less to allow my DR army to live.
My line voltage is 120 and my watt meter reads 14-16 on numerous old heaters.

Mt friend coupled 2 10w/900 ohm resistors, they got "hotter than a hand can stand" when 120v current was applied (according to the service manual regarding the oil conditioner), he ground them down to fit in the hole and applied thermal paste, put in new wiring to the relay as the old was completely shot, and it draws a steady 7.2 watts with the system off according to the Kill-A-Watt. The compressor set at 5 ("normal")is nearly silent even with the kitchen at 62F. The resistance may differ but the compressor is doing well and everything is at near spec except I'm using less wattage. IT WAS NOT EASY, though; an 2-day job grinding and fitting was a misery. Otherwise, well...it works.

Great job! Glad to hear it is doing well for you. So I guess it was down to the bad heater after all.

A+ on the effort. That's why I order heaters.
Glad to hear your CA is doing well.

Otherwise, well...it works. I'm surprised at the difficulty in fitting the resistors. It only took a few seconds with a bench grinder to do mine. Interesting to know that 7.2W is working OK at present. I used two series connected 560 ohm 10W resistors. However, the important thing is that your home made heater was successful. |

I would have more CA form A's but they must have not been able to make a big boy CA.
Imagine a CA3B! A jumbo can of soup!

Well Chris if you ever need another soop can to turn up the heat just let me know I have someone that's willing to part with one !
