15 ways to put a bad oven

There comes a cold season - it's time to strive in the evenings to the family hearth. What could be better than to spend a few hours in a winter evening in a warm cozy house, where not only there is central heating, but you can also flood a real oven! Or maybe you also love to steam in the Russian sauna at the weekend? Then for sure, you need to put the stove in the house or in the bath, but so that later it would not be excruciatingly painful ... for the aimlessly spent time repairing a new, improperly folded stove. What mistakes can non-professional stove to make?
 

The first of these, the most common, is the non-observance of the simplest masonry instructions, which is the same for any masonry work, not only for the furnace: the uniformity of the joints. The seams will burn out, the cement mortar will collapse. The consequences are predictable. You should not take such a job from the master

 

 

The following photo shows the places (in sufficient quantity), where, after several launches in poor-quality masonry with wide seams, cracks appeared - and this is only the beginning

 

 

 

 

And if at the same time, when the initial cracks appear, a poor-quality brick in the masonry will also fall, then the cracking can safely “hook” on its structure:

 

 

 

 

Over time, weakened or cracked seams, especially along the edges of the masonry, will force you to remove extreme bricks - you will have to repair the furnace, and, moreover, thorough

 

 

 

 

Why seams turn out uneven? Yes, just so unprofessional masons "pull" the level horizontally or fill the space between the bricks, if they are not accurately split off

 

 

 

 

But let's move on to more complex work, and, accordingly, to more complex errors. The repair process is quite complicated, especially if you need to replace bricks. All the more so - if on the inner wall of the furnace, and not only on the lining. Replacing the bricks of the back wall can be made on white silicate ones, but only on the outside, and not in any way, as in this case. It is not only wrong, but also unacceptable to change a burnt brick to white on the INNER wall, since it will burn out in just a few days of operation of the furnace. And there may even be a fire hazard!

 

 

 

 

The place of burning out is unattractive. But you have to exchange material with big holes, so to speak

 

 

 

 

And to more "air" problems: poorly executed, and maybe - designed chimney. What is it for? And remove the products of combustion of fuel, and cravings, of course, create. And with a bad or lack of it, that is, with an improperly functioning chimney, smoke and carbon monoxide will come out of the furnace of the stove or fireplace directly into the room

 

 

 

 

If the chimney is incorrectly calculated, that is, its height is lower than the established one, then the “blowing out” of the combustion products back into the furnace furnace occurs. According to the technology, the chimney should be either higher than the ridge of the roof, or if it is significantly removed from the ridge - not below the line 10 degrees from the ridge

 

 

 

 

If you break the chimney vertical, the chimney can simply break - this also happens

 

 

 

 

A separate song - when the chimney or any chimney spread on the wrong solution TU. Then it successfully falls after exposure to such solutions of high temperatures. This, for example, was due to the fact that the pipe was folded onto a mud-sand solution:

 

 

 

 

And if the pipe is not insulated from the roof covering, then due to the temperature difference its material will quickly deteriorate, which can also lead to chimney failure.

 

 

 

 

And in conclusion - examples of unsuccessful options for homemade fireboxes. Why so pervert if you can put ready-made grilles?

 

 

 

 

This is the furnace in the bath stove. So much iron, and even such a massive one, probably in order for the heat to last longer ... But the lattices in the furnace are not made for this, so the heat in the bath is not preserved

 

 

 

 

And here, after a short operation, the furnace of the new furnace had to be re-searched. Competently had to do right away!

 

 

 

 

Such a simple at first glance stove, and so many problems can be! Still, the stove-maker is a responsible and necessary modern profession.
