High Heat Loss

Re: High Heat Loss

Jcampo,

JE's probably correct, but without more information, it's a difficult situation to call. I'm to the north and east of TO, about 70 kms from downtown. If you'd like to have a look at what I've done here, send me an email through the forum and we can work something out. I'll reply with my phone number, too, in case it's possible for me to have a look at what you've done and make some recommendations.

Re: High Heat Loss

Tell us more about your oven - have any pics?

What form did you follow?

Rough guess is it sounds like you need more insulation if it is not holding the heat. Is the underside of the oven warm after you have fired the oven? Is the dome of the oven warm to the touch after you have fired the oven? If the answer to one or both is yes then you will need more insulation.

Did you use fire brick or insulating fire brick? - there is a difference? If you brick is insulating fire brick then it will not hold the heat?

we need more information

welcome aboard

We have just finished building a wood burning oven and I wish I would have found this forum prior to building it. What we are finding is that even if we have a good fire going for a few hours prior to cooking, without a big fire going the heat loss in the oven is very high. We can barley manage to cook 1 pizza. The fire bricks just don't seem to retain much heat for long.

Anyone have any ideas as to what we can do? Can we add additional insulation or another layer of fire brick?
