UPS for Whitfield Advantage Insert

[hamhock75]

Earlier this year I bought a used Whitfield WP2 Advantage Insert without the igniter. It works well but I soon discovered that the power only needs to go off briefly to turn the unit off. I tried my APC BN450M 450VA/255W UPS but it did not work.

Thread 'Electrical Consumption of Pellet Stoves'

Jan 31, 2011

Have you ever wondered how much power (watts) your pellet stove uses, or how much energy (kWh) it consumes, or how much it actually costs you on your electric bill to run it for the season? I measured the electricity consumption of several pellet stoves with a P3 Kill A Watt meter and found they average between about 125 Watts to 150 Watts instantaneous power draw depending on the auger and blower settings.

Here's some actual numbers from a 20+ year old Whitfield Advantage II T Insert. During the monitoring period of approximately 2 weeks the stove was running 24 hours a day, only being...

I bought a GoldenMate UPS off Amazon for $159. It works great. After charging it, I ran the Whitfield on medium settings for 1.5 hours. The charge indicator dropped from 5 to 3 bars in that time. It has power indicator that confirmed the power consumption found in the above thread. Power use was between 75-120 watts. Most of the time it was around 100 watts.

I forgot to mention but one of the most difficult things to figure out about a UPS is how long it will run. For example, a unit specified at 800 watt-hour running at 100 watts does not deliver 8 hours ( 800 wh/100w = 8 hours ) because capacity depends on load. This unit had a second specification that it would run for 30 minutes at 400 watts. Since capacity goes up with a lesser load, it is fairly safe to assume it would be possible to get at least 120 minutes or two hours at 100 watts. Since it ran for 1.5 hours dropping 2 bars out of 5 ( 40% ), That would suggest it can run for 3.75 hours at 100 watts ( 1.5 hours/.4 = x/1 or x = 3.75 hours )

I pulled the plug on the UPS and let the stove run at medium settings until it quit. The UPS ran it for 2.5 hours.
