i would not consider electrical parts "warranted items" unless they fail in the first year, the manufaacturer of your stove is likley just passing along the waranty he can get on them...it is the parts "he' builds that you want a great warranty on
i have a home built stove it is in its 8th winter and i think it was about december i had to add a new solenoid to run the damper and this week i installed a new blower for the air supply....i think ihave done well by these two items
lets face it folks...most warranties have enough loop holes for the manufacturer to escape costs
most furnaces are built to last about 10 to 15 years (just like most other furnaces) sure we all hear stories of someone who has one last much longer (the same with gas and oil stoves as well) but those are the exceptions
most every major appliance you buy has a general life less than 15 years..stoves, fridges,tv,washer etc.
most will go longer but maintenence cost will rise dramatically. these stoves in my opinion are not different
you buy a new oil stove for under 3 grand...now you pay for oil at say (in a farm house in my area) 2000 to 2500 a year for ten years you have close to 30 grand spent
you buy one of these wood stoves for 10 grand (installed) and burn wood for ten years that you cut yourself you probably have well over 20 grand invested with buying of saws and transporting wood and such..some folks maybe more (as in my case)
as in my case i bought a new tractor..a new dump wagon and a winch probably near 50 grand but it is not going out the stack..i know i will not hurt the machinery and likley when i am ready to sell it i will recoupe the same (or close too) the prices i paid. about hte only thing that will lose value are the chainsaws. i have heated with wood (one way or another) for close to 25 years and i think i can do it for another 10 or 15. cutting wood has always been a 'family affair" for us and we all enjoy the time in the bush together
if i could not have built my own stove i would never have bought one (they are way over priced in my opinion)
those that buy a wood stove to beat the fuel prices should first consider insulating your home to the maximum first, you may find the heating bill will drop to a "managable" amount to spend and not have to consider wood as an alternative...and remember, wood heat deprives you of all those other comforts...never having to be there to fire it..if the power fails for a few days you oil furnace wont freeze...you only have to pay for fuel..not go out and cut it, stack it, or draw it home.
sorry...mid week ramble
