Anyone using a Keystoker HF70

Its very possible Im wrong, but arent the 70 and 90 the same stoves but with something added or removed inside?

If you keep all the gaskets in good shape and no other air leaks it should idle real low. And as crazy as this sounds, you can always open a window during the mild weather when the stove is running thru low amounts of fuel anyway. It will still be cheap to operate at those times. Lots of us have done that. One member that hasnt posted here in years used to leave a window open year around in Maine just to bother his neighbors who used oil. lol

There are other ways to make it run cooler too. As long as it doesnt get choked up too bad with ash and it gets a little under fire air it wont go out.

The hf90 has 3 grates and the hf70 has two grates. The 90 is 21” deep front to back and the 70 is 19” deep. I will heating about 1900 ish square feet of very well insulated home. I have a coaltrol on my 105 keystoker and it rarely runs a large fire.

I would say that you could idle a larger stove, but you can't run a smaller stove higher than its max.

I see you have a mark II. That is the same BTU as the HF70. How many square ft are you heating?

Doing the math you only used about 25 pounds a day average with the stoker so I would think the 70 would be fine but the 90 would be ok too. Thats my opinion anyway.

If you have the toyo hooked up and ready to go all the time for the worst weather possible that would be great . You just dont want to run the 70 or any stove at 600 degrees all day to stay warm. An extra stove is the best heat insurance you can have. Waytomany's comment is very true.

It's not the sole heat source. I actually am doing the opposite of most here. THE stove is in an uninsulated basement with the wood pile. I run it in shoulder seasons. In fall it helps dry out the wood and heats basement. It also keeps the floors warm down to highs about 30.

I’m pretty sure I can make the keystoker hfh70/90 work on my hearth? Taking some measurements this morning after speaking with Don at keystoker. I’m keeping my fingers crossed.

I even mock things up with cardboard to visually see how things can clear. I often times are being told give him a minute so he can overthink this!

Just ordered the HFH70/90. I going to tee off the back and two 45’s to connect to my ceiling A stove pipe heat shield on the vertical section off the baro will keep me well within clearances.

Nice. The hopper is a very nice feature, especially if you are gone for long periods.

You will never regret having a hopper. If dust becomes an issue you can always mist the coal with peanut oil.

If the day comes that I buy a brand new stove, that is the model I hope to get. Very nice looking stoves. Hope it works out well for you.

Was a though decision. Wife really wanted a hopper stove. The HFH 70/90 has the best clearances of 12" sides and rear.
The next choice would have been the hf 90 followed by the hitzer 254. I also liked the fact that the hf 90 is also two stoves in one. It has three grates and the rear one can also be disconnected similar to the hfh 70/90. Don at keystoker told me this. We are going to pick a color in the next day or so. I will post pictures and report back on performance. Thanks again for all the help.

What do you mean two stoves in one?

I’d like to see some up close internal and external pictures of the inside and outside of these. Not much info here about them, nor detailed photos.

My big Hitzer 354 sits 9” from my hearth wall. Granted it is a blower model, and the fact I never have to run it hotter than 350F, the hearth wall behind the stove is always cool, less than 125F and in places around 95F. Far less heat behind the stove than with my old wood stove. Not even close.
