Tank you very much for the offer. But I have been thinking for a while to put the project on google code so I did that. Here is the project and browsable code: http://code.google.com/p/heating-monitor/

I hope it will be of use.

Thank you! I will update on the progress.

The box I got here: http://swechtrading.se/zencart/index.php?main_page=product_info&cPath=51&products_id=256. I had to cut out the display myself and if you look closely you can see it is not perfect edges. But it's homemade so it doesn't have to be perfect smiley.

I really like the idea of morse code. I will defenetly look into that. The furnace already have lambda sensor controlled air intakes. Otherwise I would probably have done some tinkering there as well:). What I have been thinking about is to add a function to lower indoor temperature at night. The control system I have for that does not have that function.

I will look into putting the code online somewhere.

Thank you for the feedback.

I have built a central heating monitor system which is based on the arduino and it's boot loader. It's made up of a network with 1-wire ds18s20 which measures temperatures on a wood furnace and it's heat storage tanks. Connected to it is a display unit with a dogl LCD display.  I'm quite proud of the display which has menus for setup and preferences and also makes a limited logging. Future plans are to make a logger unit in the 1-wire network with sd card and wifi.
