OK guys, I'm getting the picture. 3 boxes: Heat sink, Burner, Insulation.
I spoke with my handyman this morning to check out burners. He confirmed what Scot and others have already told me: said that reliability/safety is a problem, he could make them but they would cost a fortune and I had better by them from Thailand. 1st rough estimate $160
Regulators available here are cheap Chinese that always have probs - buy in Thailand. Estimate $160
Thermostats _ same deal - buy in Thailand. Estimate $250 Shuboyje, what is PID?
I'm tending to agree with Shubs. I think the majority of the work will be in finding the stuff at a reasonable price and fitting it will be marginally more complicated. WFO, top heat : traditional decks, bottom heat. Both have their problems. Why not get the best of both worlds and do both. Assuming I went with 152 btu and did a top and bottom burner. What do you think the distribution should be re: top and bottom?
About the shell. Quick estimate was $600 for stainless 'boxes'. $200 for kiln shelves because we would need to get them machined specially. $160 for metal stand.
These estimates are really outer ball park ideas! They bring me up to $2000 which would then overun due to 'extras'. I was rather hoping to get is done for a lot less (maybe half
) but it atkes what it takes and its still doable. If you guys think some of these figures are out of the ballpark and in the next precinct then let me know.
I'm rather hoping I can find somewhere in Thailand that can sell me the whole works so that they are all rated to be compatible with each other. If anyone knows of a supplier there or a good 'find it' man, please let me know. I have to go there in about a week but I don't have to stay for more than a couple of days.
If I can't find the burners we would make out of copper here. Just sayin'. But the regulators/ thermostats, we can't.
Thermocouples installed in the floor - I'm not there yet in my head - but I think I had better arrive there before I get to Thailand!
One last thing - no-one understand the concept of a pilot light in this country. Every thing uses a magneto type spark to control temperature. Is there anything inherently wrong with using this? I'm hoping I can get a favorable answer here!
Thanks again for all your help.
