Depends on the TM operator, and the TM it is installed .
What do you mean, what about the operator should affect the longevity of the exhaust heat exchanger construction? I don't understand the reference.
We have many of our DC that are 6-8 years old, with no failures.
Of those units what type of average temps do they hold? and what average wand flow gpm?
I ask because, it's easier to use a heavy wall construction that is less efficient in energy transfer if all you are concerned about is longevity.
The failure rate on our TM's is less...
than the % of coils we replaced on Little Giant #3 heaters (running @ factory-set temps).
Since you mentioned the comparison, just curious how many units are out there with little giants compared to HX? As it would affect the comparison percentages dramatically. I must say, the little giants are a pretty reliable heat source, I'm surprised at the heaters out there for 10+ years still continuously in use with original coils.
They also:
1. produce more heat
2. reduce fuel costs
3. reduce non-productive refueling time
4. have less probability of a fire.
So you are saying that your existing 6-8 year old HX units produce Higher temps than an equivalent unit with say...a #3 little giant?
Back then what was it, a 20-24hp Honda?
I find it hard to believe a mid-range v-twin could surpass a 120,000 btu heater.That is the primary reason you see LARGER engines used on TMs today, heat generation because the smaller engines jsut didn't burn enough fuel per hour to create the BTU transfer.[/b]
We were among the first in our industry, to use a heat exchanger.
That experience gives us advantages of experience.
What's not to like ??
