Thanks Jon ... i appreciate it.
Our friends up in Canada have a profound influence down here just south of the border in Maine. We get all of our petroleum products from a Canadian owned oil company called Irving Oil. Irving corporation owns vast tracts of forest that was once paper company land. Just recently, Emera, out of Canada, took over all of the electricity distribution for the entire state. It's sort of a running joke but if we were ever annexed by you most of us wouldn't know the difference.
You know ... for the most part things are running pretty well. It's a positive influence.
Emera Electric has been promoting the use of heat pumps for a few years now. It's early yet, but the feedback that i'm getting from folks who changed over has been mostly positive.
As a carpenter / contractor i've got to be very careful about the new technology that i incorporate into my jobs. If a customer tells me to do it a certain way then that's what i do. If an architect specs out a job using new methods i do as i'm directed. It's different if i bring in something new on my own because then i'm the guy who is responsible if it doesn't work out. I'm cautious ....
I've been in the trades for about thirty years now. I started out as an apprentice and after five years worked my way up to journeyman. After sixteen years on the different construction crews i went out on my own.
There were a lot of changes in building technology over the years. We were doing a lot of high end and commercial work. If memory serves it was sometime back around 1982 that the practice of using a vapor barrier on the inside came down from up North.
I hate to be an a$$ but that's something to avoid using. It's been a disaster down here so we've discontinued the practice.
If you think about it things in nature always try to even out. If you heat your home to 70 deg on the inside and it's 20 deg outside that heat wants to travel out. If you shut off your heating system the inside of your house would be about the same as it is outdoors.
It's like that with vapor pressure too ! If the air is moist inside and dry outside that water vapor wants to migrate outward. It will do that as long as it doesn't hit a restrictive barrier. If it hits a barrier it condenses into liquid water and runs down. That causes all kinds of rot problems.
That's why they favor Tyvek & Typar on the outside now. It's like a fine mesh screen. The wind blowing at you from outside is air molecules which are fairly large. Tyvek stops the wind. The water vapor molecules are smaller though. They're allowed to pass through to the outside air and it all evens out.
As an example of a new thing : I used Dow Styromate on a new place that i was building one winter. I was heating the interior with a propane heater so it was kicking a lot of moisture up into the air. I noticed that there was freezing going on behind the styromate housewrap. I had to re-sheath the entire place with Typar at my cost because it was my fault. ~ lesson learned ~

I guess the auger timing speed is a problem with the pellet stoves. From what they told me the fire was chasing up the auger into the pellet storage bin in the back ? Othertimes it was feeding too fast and overfilling that spot where the pellets burn ?
There are at least half a dozen waste oil furnaces that i know of in this area. They work really well !
The outside furnaces aren't too bad. The newest ones burn so clean you would never know they're running. The big thing with those is that they need a long run cycle so you have to store the heat somehow. It's usually done with underground hot water storage tanks that hold over a thousand gallons.
I was talking with one of my neighbors last year and his was short cycling and plugging up because he didn't have that kind of storage. He was planning on pouring a concrete slab over the dirt floor in his basement that fall. I suggested that he run PEX in floor heat and treat it as a separate heat zone. That way he could have long run cycles and store the excess heat being produced in the thermal mass of the concrete. As heat rises it would eventually work it's way up into the house anyway. Doing it that way worked out for him last winter.
There's so much new technology out there and there are so many different ways you can use it.
Got to admit though .... I'm partial to simple. We always heated with oil because back when we first bought our home heating oil was only .55 USD/gallon. We were going through over a thousand gallons a year to heat our home and produce enough hot water for a family of four.
When the cost went to 2.00USD a gal. i replaced oil boiler with a new higher efficiency model.
When it went to 3.00 USD a gallon i switched us over to wood heat. Our wood stove is really simple and straightforward. We have a one storey ranch. The wood stove is in the basement. We heat the basement and that warms the floor. It's about the same as having in floor radiant heat. It's a really nice even heat. The house is warm & cozy even on the coldest days.
We still get our hot water from the boiler but i made a pre-heater. The idea is that the water coming in from the well is about 50 deg. If you pre-heat it somehow that's less oil you are using to run the boiler.
I put a hot water coil on the side of the woodstove and that thermsiphons into an 80 gallon stone lined hot water storage tank. The tank i picked up off the dump and the copper tubing & fittings i bought new. Total project cost was about 120.00$ There are no pumps or other moving parts to wear out. It should last 35 - 50 years with little or no service. Even now ... that coil is picking heat up from the 70 deg air and pre-heating the incoming water some. It's worked well for the last four years since it was put in. We're now down to under a hundred gallons of fuel oil usage every year.
Sorry to derail the thread ..... I'm a geek.
