That 94% efficiency rating on the Integra is a bit hard to swallow. How the manufactureres arrive at this conclusion really needs to be defined and standardized.
It is already quite standardized in Europe and also strict regulated.
You forget that the Rika Wood Pellet Stoves are made in Austria. Europeans like regulations like no one else. Austria has very strict guide lines concerning environment protections and efficiencies concerning Wood Pellet Stoves.
We have the EPA in the good old USA and our rules are just a little bit more relaxed.
If one reads the different manuals of Wood Pellet Stoves, you will see that a lot of them are just EPA exempt, but a few already are better then the given
EPA Standarts and are called EPA certified. It's that simple
Investing $4K+ in a space heater isn`t a wise decision in my view and would make me think long and hard about re-zoning my present hot water system and ...
WOW ,if an Integra is twice the price as a BIG E it had better 200% efficient for me to give up my BIG E
There are people who drive an AUDI and other ones which are driving a CHEVROLET.
It is a personal taste and preference, so goes the story for Wood Pellet Stoves.
I can not envision a Wood Pellet Stove like the Big E in my livingroom, it just does not fit in my home. But that does not mean I have to knock the product.
Different strokes for different folks!!
