F45 v2 vs. F35 rockwood

[Zuluwhiskey8786]

Hey y’all,
New to the forum but not burning a stove. Im looking to update my Brunco 1800a wood stove. Things older than me and looking to get into the Jotuls. My house is 1200sq. Ft. With two bedrooms on the 2nd floor. I have an oil furnace for the really cold days to keep the pipes from freezing in my home and it is an old house. The current stove is hard to manage when burning as the spring in the side that maintains the auto damper is warped and the prices online for “vintage” parts suck. Anyway it gets ungodly hot in the house. I was looking at at F45 v2 rated for 1800sq. Ft. But in zone 4 it shows it’s good for a 1500sq ft. House. I was also recommended to buy the new f35 that’s rated for 1300 sq. Ft. But in zone 4 it’s rated for 1100 sq. Ft. Any thoughts? For the price point and the summer savings jotul has on the website right now the 45 would be the most practical as far as taking 18” logs vs the 35 only takes 16”. Not looking for any CAT stoves. Any suggestions or thoughts are greatly appreciated before I pull the trigger on the next two weeks.

How large is the room the stove will be in? I really don’t like loading my 1.7 cu ft F400 every 5-6 hours when it’s cold. So the F45 would probably be my choice. Look more at burn time and low output. Have not read many reviews of the F35. The 45 get good marks.

The room the stove would be in is a 12 x 19 rectangular living room. With all other rooms branching off.

That’s not a large room. Layout matters if you don’t want the stove room 85 degrees or more. Post a quick skeet you can.

If your goal is just supplemental heat the 35 would do probably do, and I’m just guessing, 70% of the heating. There will be lists of cold starts in the morning. The 45 would do more and allow longer burns but air flow matters as must as the size of the stove when taking about comfort.

Also there are 2 bedrooms upstairs

How good is your house’s insulation?

I’d say ok. But it’s drafty. I plan on finishing my enclosed porch in also for livable space. I wish the f35 took a longer pc. Of wood. I’d have to go out and recut all my wood to fit in the stove if I bought it. The guy at the store told me he would put the f45 in. But another store told me it could be too big.

Go with the F45. It burn well even with half loads. It’s also very controllable in the low burn setting for a non cat.

 

[EatenByLimestone]

Personally, I’d go for the 35. You don’t have a large house, and you’re kind of Southern. The room isn’t large, but heat transfer shouldn’t be too bad with your layout and it sounds like you’re fixing some of your drafts. With the larger stove, I’d worry about not being able to sit in the stove room if it’s above 30 degrees outside.

I’d also seen a f3 on fb marketplace but it’s a couple hours away

It would heat the whole house though? I wish the firebox was a bit larger

 

[EatenByLimestone]

The firebox size is why I went with it! But yes, 1.5 cubic feet will heat an 1100 sq foot house in PA. I think youd have issues with a 2.4 cu ft firebox. But that’s my opinion! Todd runs the stove! He has way more experience with it than me! As Todd mentioned, you won’t get as long of a burn time with the smaller firebox, but you won’t be filling the larger one up to take advantage of the size either. In Northern Wisconsin, Todd is going to stretch his stove’s legs a little more! He gets times that the difference between inside and outside temps is 100 degrees! I hope you don’t see that in Southern PA!

So the next thing to look at is your chimney. New stoves let a lot less heat up the chimney than older stoves do and that makes them much more sensitive to things like chimney diameter, height, and insulation.

Well I just replaced my steel roof last September. I replaced the old chimney pipe with new Selkirk double wall 6” pipe outside and 6” single wall from the stove to the adapter in the roof. I’d say the chimney is about 13-15 feet in total height and it’s a straight shot with no bends.

 

[EatenByLimestone]

You may be right on the edge on chimney height. You may need to add some height for shoulder season running.

 

[Zuluwhiskey8786]

Hmm so go get another pc of double wall and twist it on top. I’m not against the 35 the only thing is I just don’t want to spend all that money and then have to work the stove hard. Also I’ll have to saw all of my seasoned wood. Can you run half loads in the 45?

Yes I burn half loads for those take chill off days or sometimes when it’s well below zero I’ll burn half loads at a medium setting to keep the stove hot and keep the coals from building up. I rarely stuff it completely full, I probably utilize a little less than 2 cu ft of the fire box most of the time. It’s nice to have that extra volume so your not trying to play Jenga with your splits.

I think the F3 has an even smaller fire box than the F35 so not sure if your firewood will fit.

Have you looked at the F445? It was just recently released as the replacement for the F400. I was really tempted to try it but just couldn’t pull the trigger because of other expenses that came up.

I did look at the f455 but I’d rather not get anything catalytic. I know alot of people say you don’t have to use it but I’d rather not even have it. I’ve been saving for a while and I feel like I have this money burning a hole in my pocket hahaha. I’m super excited to get another stove I just don’t want to get a stove that I’ll have to burn like crazy(smaller stove) or one that I won’t be able to burn hot enough and still get decent burns out of overnight without walking around in my underwear. This is the current stove and she rips. 29” long fire box and 13” deep

Living room is 23x13

Yeah there is some extra maintenance with a cat stove but it’s really not all that difficult. Just brush off or vacuum the cat about every cord of wood or so. The new Jotul cat design has larger cells and no bypass so you pretty much just run it like a non cat. The jury is still out on this system. What really caught my eye on the F445 is the auto secondary air control. I wish there were more stoves with this.

I won’t lie there are times when I open a window or two because I got it too hot in my cabin. That can happen with any stove, no big deal fresh air is good for you.

Well, I think I’ll go for the f45. I do ALOT of hunting and I’m generally not home a whole lot and I’d like to have the stove burning while I’m away and at work. I think I’d rather be a little warm than constantly lighting and relighting a fire

Not home a lot. That’s the reason you want a 2+ cu ft stove. With the big firebox you don’t have to be picky about high BTU wood.
