I would like to move heat from the stove to a unheated porch. If I put a shield on the back of the stove and use insulated duct,and a 500cfm fan. Would this move enough warn help? The porch is well insulated and is mostly glass.

I kinda doubt that you'll make THAT much of a difference...
Your last statement is conflicting.
Your porch can't be both "well insulated and mostly glass"...
Glass has no R value, so you're probably lose whatever
heat you pump out there...
Thanks for the reply, the porch stays around 60 most of the time. I just wanted to raise the temp alittle to sprout seeds. Guess I will hook it up and see what happens. Thanks again.

My parents put in a sun room a couple years ago. The room is mostly glass, and stays very comfortable with a heated floor because it is made with insulated double pane windows.
My suggestion, Larry, would be to do what you can to encourage natural convection currents. Placing a fan in the sun room moving the cooler denser air into the warmer part of the house might actually work better at encouraging warm air to come in above to replace it.
Does your sun room have a ceiling fan? You might consider running it on the lowest setting, and set to that it moves the air upwards. This will pull cooler air up to the ceiling forcing warmer air up above to come back down along the walls.
Many of us have found that it usually works better to move the cooler denser air in order to displace the warmer air to where we want it.

I've tried the ceiling fan, didn't help much. The porch is lower than the rest of the floor. I'm hoping to pull enough from the back of the stove to raise the porch temp 5or6 degrees. If it doesn't work I'll have to try something else. As always thanks for the imput.

Inlaws had a florida room put on the back of the house and always kept their study window which connected open. That and the ceiling fan cooled the room nicely but didn't quite heat it, so they put in a Kerosene heater. That did the trick. They didn't run it all the time but it made the place warm enough to enjoy. Father in law was disabled and spent a lot of time out there. That might be enough to booste the temps for an hour or so in the morning or afternoon for you. or you could also try an electric oil filled radiator. They don't usually burn too much energy.

Quick update, hooked up the fan and ductwork. Wired it to the line voltage thermostat runs with more flow than I expected.Have to work 12hours allnext week good thing only 6 days. Will pick up what I need to make plentum and try to get that laid out. Took some temps off the back of the stove at normal burn it was 500f does that seem about right? It is a steel plate stove If that matters. Thank for your opinions everyone.

If you want to sprout seeds, bottom heat matters more than overall room temperature. You don't need a special heat mat, just use an electric blanket or heat pad covered with plastic (to avoid electrocution). Check temps to make sure the soil doesn't get too warm. Tomatoes and peppers like 80-90, I think.
Be sure to aim a fan at the seed flats once the sprouts are up, the air movement helps prevent damp-off, plus it makes for stronger plants.

Larry,
Hate to be a bummer and not sure what your plan is, but building a plenum/shield on the back of a stove and blowing super heated air around your house is not generally regarded as safe. If you wanted to collect air from the ceiling of your stove room (e.g. <150F) and blow it wherever you want, there may still be code issues, but probably aok. Alternatively, you could collect cold air from your glass room, and blow it to your stove.

Anette, I have heat pads from reptiles that will work , didn't think of them thanks. Woodgeek, so every forced air furnace ever made was unsafe? Guess I think I'll finish and see what what happens. Thanks again for the help.
Had a rare day off and finisher this upgrade on my stove. With the stove at normal temps the fan moved enough heat onto the porch to turn off the thermostat, set at seventy degrees after two hours or so. Now when I load the stove I will set the timer for six hours and power the thermostat. Hopefully it will be fall before it will be tested at freezing temps. Glad I gave it a shot just can't bring myself to buy liquid heat. Again thanks for your impute.

Nope, but they were designed and tested to be safe as forced air furnaces, including eventual fail-safe, in order to be certified so you could buy 'em. YOu can do what you want, I was just trying to suggest different means to the same ends that were inherently safer (like moving ceiling air or cold air in the other direction) that others here have found quite effective also.
Glad you got your system working.
