Try Hot2000 - simulates energy performance but also calculates load.

Not a professional opinion:

There's a video online of a guy testing sealants in a sealed jar with water and refrigerant - the sealant never solidified; was just white goo.

I would post it but youtube is frowned upon on this...

Why not just insulate the damn duct? I would have been less work.

If they go through with this, a lot of contractors in the south are going to start illegally importing cheaper 13 seer units from the north, and vice versa with furnaces.

I read that they dropped...

nah - let 'em freeze; the players and spectators. Outdoor heat is stupid. :p

Want to be warm? Go to an indoor event for god's sake. :rolleyes:

Sorry to burst your bubble, but if it's outside - what a waste! Seems as if people are very adept at finding new ways to waste energy when we need to do the opposite.

How much do you get payed per kwh? Is it the market rate or are there subsidies down there? (meaning it's done at the expense of others ;) )

Financially there might be a good reason to go solar in...

There's one called r22(insert proper letter here ---> x<---) which is sold in Canada. I think it's basically propane. :eek:

^best advice in this thread :)

(community) College is good if you find a good program and want to learn practical skills. I was just saying that many college programs attract not so good students.

In Ontario, I think you can do...

I have been through a technical program like that (not a hvac technician program, and not at george brown)...

Don't even think about doing the technician program - go for technology. The Ontario...

There's been a lot of talk about the negative impact sealants can have on equipment if the refrigerant is contaminated with moisture.

Presumably small factory charged/sealed systems such as window...

...sounds like those steam units are just like electronic air cleaners - good on paper, completely useless in the field.

Energy illiteracy is the greatest impediment to properly sizing furnaces.

Most salesmen and installers probably don't even know how to convert between kw, BTUs, and tons.

They probably don't...

How do you know that the customer wouldn't know the difference?

Shouldn't customers like that not purchase 2-stage furnaces to begin with?

Why not just offer it as an optional upgrade?

svchost isn't the bad process itself - it's just an executable file which hosts some processes.

You have to find and delete the infected files, then remove the registry keys associated with it.

It makes sense for governments to subsidize r&d, but not the deployment of immature technologies.

Define "investment grade"

Seems to me as if ALL "soft asset" financial investments don't have a guaranteed rate of return, and many of them are most likely scams. Why should energy related hard...

^The only problem is that if even 10% of the property owners in your area sign on, the subsidies will get cancelled to control costs.

Excuse my use of metric units - I have no idea how much energy a cubic foot of gas has.
