No heat from Stove ( Jotul )

[GarethM]

Well you seem to believe you know better, yet don't want to start again and solve the actual problem.

 

A smaller stove will be fine once it's not throwing 99% of your heat up the chimney.

 

Just remember that old open fire before the Jotul was 30% efficient, bigger is not always better.

 

If you want to test my theory, board off the fireplace and run a couple of 3kw electric heaters and see how toasty it gets one evening.

Can't hekp but think that the bloody great hole in the register plate might be where a significant part of the heat might be going.

 

How long do you have the stove burning for?  We used to find that it could take a good hour or so for our old one to get up to temperature (A Vermont Castngs Defiant Encore), but you could then cook on the top of it. 

 

As others have said, if you are buring wood as well as it appears in the video then the heat has to be going somewhere and, if it isn't out through radiant heat, then it can only really be up.

I guess you could say that Jøtul is specifically designed not too. Since the heat is ment to radiate out the front/ top/ sides.

 

Putting a stove in an alcove is a peculier British thing to do.

 

Send them an Email and ask? I bet they answer quickly.

I had two stoves just like yours, both were free standing. Even then I swapped one out for something bigger, the other chimney I blocked off.

I agree the register plate is VERY badly fitted , so a lot of heat must be escaping …however still doesn’t get over the stove not getting up to temp despite me loading it full of good and expensive woood !! I only light the stove in the evening since it’s in the sitting room , so I think buying cast iron stove in hindsight wasn’t a good move , I’d be better suited to a steel stove that heats up quicker ( but doesn’t retain heat for so long ) this type of stove is more for a run all day type of use . I’m using it for secondary heating and a good old cheery glow !

Its got no refractory lining of any sort . This cant help matters .

It’s not that I “ seem to know better “ at all , otherwise I wouldn’t be on here asking for advice . I just fail to understand how replacing a perfectly good liner is going to help with the problem . That’s all . Plus I haven’t got unlimited funds to pay thousands of pounds to have this work doing which would mean scaffolding  . Perhaps you are right re the 5kw , it just seems to me that I have quite a large room and therefore concerned that a bigger stove might heat that area .

I will chip in again to say that not only did we have the same stove, also installed quite poorly probably 17 years ago, but we’ve also got a similar sized room. 10x5m, though the ceilings are only ~2.5m there are 7 windows and it’s a 190 year old building, so there are draughts.
 

Given the poor performance of this Jotul in our room I was also a bit unconvinced about getting a smaller one installed. Two months in I’ve no such regrets. It’s better in every way as far as I can tell. Where we used to have the stove singing for hours it now just ticks away nicely and pumps out the heat.

Now that is an interesting reply thank you !! Tell me which stove did you buy to replace ?

We had the exact same stove. It was in a not dissimilar alcove and took ages to really heat the room. Probably 1-2 hours of enthusiastic burning to get some warmth from it. When we had it out for chimney work I found a manifold plate on the back in pieces. I’d check that out If you can. The top isnt screwed down so use fairly easy to get in and out. 
 

We replaced it with a DG ivar 5 and the difference is phenomenal. Though the ivar is noisy. 

Sorry to sound stupid , but how and where do you check the manifold plate ? Sorry only just seen this …had so many replies so that answers my previous question two minutes ago ….sorry 😊

There are two plates bolted to the back of the stove, may be covered by a heat shield. I can’t remember how long you’ve had this installed, so it might be irrelevant. I suspect ours suffered from being run so hard so regularly.
