Sorry for the delay! We're really getting swamped with orders here, and I had to play "answer the phones" for a day or two. Anyway!
1) who will handle this and determine who will pay
The contractors will handle 100% of the warranty work, but Bosch/Janfire will supply your parts for free if they fail within the warranty period. I'm not 100% sure about the warranty because Bosch is being slow with getting us warranty.pdf >:[ I do know that it complies with Maine's required 5 years for the boiler and 2 years for the burner.
2) will the contractor who installed be adequatly compensated for warranty
That depends on your definition of "adequately", "compensated", and "warranty". Adequately? We'll be competitive. Compensated? He'll bill SOMEONE for the time, but we are leaning towards a mixed pay-for-labor (standard on most heating appliances as I have been told) warranty. Warranty depends on the part that failed and the time at which
3) who will stock parts on this side of the pond or will customer wait weeks for repair parts
Parts will be stocked this side of the pond, and you'll more than likely not have to wait more than 24 hours for a part during the business week.
4) If MES goes belly up where does that leave the customer?
Backed by Bosch Thermotechnologies and Janfire, who are already supporting identical systems as they are some of the most frequently installed parts in regards to pellet heating.
5) if local contractor who installed goes belly up or gets out of the business will MES pick up the mess
You'll be picked up by another contractor local to the area. For example, we're going to have at least 4 (low estimate) contractors from Portland after this Friday.
6) if MES goes belly up and customer has funky storage system which uses the new pellet truck to fill
his hopper who would he turn to??
The technology is widely adopted in Europe. You can get a bin with hatch access if you want to "disaster-proof" your fuel supply chain, but we probably won't be going anywhere. Even if we did, it will be a standardized coupling, and we'd have to sell our trucks, distribution nodes, etc to someone anyway, and they'd probably "take up the slack", so to speak. I don't think Les is going to let his business fail very soon, though.
TGun, feel free to post your dad's questions here. Our BTU/hour is 100k or 150k, depending on how leaky and big your house is. The way our system works is that it measures the amount of heat your house is losing, then puts that heat into the house at a constant rate. That way, when your house is set to 68, it stays at 68, instead of dropping to 67, having the heater fire full bore for 3-5 minutes, and warming up to 69. This also lets us size our boilers a little smaller because we don't fire at full capacity when we need heat. The burner itself modulates from about 17 kBtu to 150 kBtu.
Soft vs hard wood pellets: I hate to be blunt, but at $250/ton (for a typical 4 ton load) with free delivery with 25 miles, it doesn't matter. We have the cheapest advertised, delivered price for pneumatic delivery, and we are contracting for a more-soft-than-hard mixed premium pellet with a consistent Btu/ton.
