Hi Mac,
We have used tiny RV-type propane hot water heaters (ie 1-2 gallon) situated at
base of generator, plumbed into the coolant system with a thermostat control
and it thermosiphons. One site has a 30 kW Kohler genset with 6 cyl GM
industrial engine and this has been in place for 5-6 year
If you also have the local electricians selling the kvar units as
surefire ways to save 30% on your electric bill, I'd nominate that as
myth/scheme/scam, though I hope most of those resellers are doing so
only because they're naive. There was also some absurd company a few
years ago which was s
You might want to look at sunmodo they work well and will not leak check it
out. Some sealants have solvents that eat away shingles over time and can
create a bridle shingle that can crack. Roof warranty may be expected when
direct contact sealant is used on shingles should check with manufactures.
I'm like Tom and Ray, it is hard to avoid shingle damage on all the
connections involved with flashing on asphalt shingles, and while I've tried
QuickMount flashings, I'm confident that L-legs with (and I use
polyurethane, and am not stingy with it.) sealant are quite adequate.
Especially with roof
Fellow Wrenches,
Last year I prepared an hour's presentation for our local Solar
Fiesta on "Energy Myths, Schemes and Scams". I covered mostly PV and
the solar industry, with a few slides about the physics of wind and
those cute spinny yard-art things called VAWTs. I als
I am only going to refer to primarily to asphalt shingles . PLEASE read the
label on the sealant you are using . Our company has used flexible polymer
rubber - based sealants rated for -40 F to 200 F that have good UV resistance

Mac,
My only recommendation is that if they are off grid or concerned about
consumption not to use one. We have many off grid systems installed in
Maine (very cold weather) that have generators with block heaters
which have been disabled. They start and run just fine without the
heater.

Hello wrenches,
Does anyone have a good recommendation for a propane block heater product?
Thanks

Hello WIlliam;
I have always wondered about gable eaves as access pathways too, but
haven't said anything so as not attract attention from AHJs ;-) I don't
have a problem with walking on gable eaves if they are sturdy enough, and
at least you'd know there's no fire directly underneath you.

Dear Colleagues:
I know many of you have been concerned about the impacts of new regulations
on roof-top solar intended to protect fire responders. I have a new
scenario to offer for your consideration:
Around here only one city has adopted codes that require eave and ridge
setbacks to pro
We are the McDonalds of roof penetrations. During the last 30 years we have
literally made pincushions of the roof we have worked on. After millions of
unflashed penetrations we have only had one leak. Observing hundreds of Carter
era systems we have never seen a mounting foot leak. Like Sasqua
