Hitzer Safe Operating Temperature

Hitzer Safe Operating Temperature

PostBy: brewmiesterbuck On: Wed Nov 07, 2012 6:30 pm

I have the 503 insert.

No need yet but I was wondering what thermometer level approaches overheating.

Hitzer doesn't give a degree measurement only saying "if the stove parts or pipe glow red you are overfiring".

So I have the thermo right above the loading door and beside the MPD control. The readings are correct enough as verified with an infrared gun.

What is the highest consistent operating temp this machine can handle? 600?

I don't know what it will be like in the dead of winter and I still have some window air conditioners to take out but the stove is operating at 300-350 and keeping the house toasty with external temps averaging in the mid 30's right now. Lowest we get is around 20 with daytime highs just below freezing.

I want to know what I can crank this too if needed or during a power outage.

Thanks.

BTW, this thing is awesome. The whole family loves it. It is warm, so easy to operate and really worry free. Coal in, ashes out, set temp. I would have had a full tank of oil delivered by now but have staived off... as my coal dealer says..."the arabs in the basement"

I installed the same model last year and I never needed to get mine above 450-500. Normally, it was running around 200-300. I installed a manometer this year just to get more info on its how it was running. I knew I had a good draft but even with the internal damper all the way in it still pulls over 1.0 when I am over 250 degrees. From what I have researched here, I believe it must be dumping a bit of heat up the flue. I not sure what i can do to make it more efficient. :help:

Brewmiesterbuck welcome,the rule I use is 500* max because if the fan stops(lose power) at that temp it will go over 600* with no air wash, but the the lower the better in my opinion(if you only need 400* then keep it at that temp,gives the stove a longer life and saves on coal.
If you need same thing just ask.Take care Keepaeyeonit :D

I agree with CTyankee and Keepaeyeonit. 450--500 whould be adequate. I also have worried about losing power and having stove temperature drift up to overheating range, especially with me at work or asleep (at work?).

Ashcat had a great idea that provides peace of mind regarding this risk--a DC to AC power inverter that automatically switches to backup power for the blower fan when line AC fails. Deep cycle battery is kept charged by the unit. I use the following product and find it quite helpful: http://www.amazon.com/Tripp-Lite-PV1250 ... e+inverter. Not cheap, but neither is any kind of insurance!

I agree that 600* is a max temp for plate steel or cast iron stoves for maximim life. I never run mine over 500* intentionaly. The hotter you go the shorter the life span.

Thanks guys. I'm not planning on running it at 600 constantly or maybe never.

I just don't know what I'll need. Given my install options i needed to go with the 503 with no option for a larger unit. 2300 sqft house, old.

This should suffice and at 250 without the blower on it has been keeping my house at 77 fairly consistently on these 50 degree days.

I should be fine at no more than 500 with the blower on.

I do like the idea of the back up. We have them at work, never thought of it.

It was cold a week or two ago with high winds. I didn't feel comfortable keeping it above 400 while away at work. Everything has turned out alright.

I just need to get two window unit air conditioners out yet. They make a huge difference. Each weighs close to 100 pounds so I haven't taken the task on myself. It's not lifting the weight as it is trying not to destroy moulding and such getting it out. Waiting for my BIL to come.
