Chimney Flues

Many months ago before the waterproof membrane, earth sheltering, PV panels and solar water heater were put in place on the roof I had to decide the exact location for the three wood burning stoves in order for the holes to be cut through the concrete and a section of chimney flue to be installed. in each hole. The idea being that at the appropriate time these sections of flue would be attached to the corresponding stoves. Fine in principle.

The bedroom stove was fitted first and required only a very slight adjustment to ensue a perfect alignment of the flues.

When the cook stove which weighs 450kg was delivered it was carefully man handled into the correct position to align the flue in the ceiling with the flue connection in the stove. See earlier post.

However, when the team that were doing a magnificent job clearing up after the flood and mud fiasco, despite my explicit request not to move the stove, decided to some how shift it from its original position when cleaning around it. I therefore had to get another team to move it back into position before the plumber fitted the piping for the water heating jacket inside the stove.

Unfortunately it was not until the chimney flue came to be connected that it was realised that the flues were now not exactly aligned. Even with sufficient manpower available the stove could not be moved due to all the water piping attached. Hence I have ended up with a flue pipe that has a distinct curve. I know that in the great scheme of things this does not mean much but, given the attention I have had paid to other such details, it is a constant source of annoyance. I take heart in the fact, however, that in a few years the flue pipe itself will probably discolour and need replacing and I will then be able to have the issue resolved.

As with a lot of things here in Crete nothing is ever straightforward.

The team fitting the chimney flues had arrived to do the job without the corresponding external flue pipes and cowls!! They did not know when these would be available and the job completed. Luckily George, the project manager, was on hand to explain to them, in Greek, in very clear, and as the way here, very loud terms that there would be no money for their work until the job was finished. Two hours later they returned and fitted the external flues and cowls!!

There still remains the chimney flue for the proposed masonry stove in the main room. With the design I am currently envisaging I will ensure that the flue is correctly built into the stove as it is constructed. See earlier Masonry Stove posts for more details.
