[gregory16]

Hello everyone,
I am new to the forum, I want to change my heating mode which currently has a wood insert that heats very well the only kuick, these when came home from work and cold the night.
On my advise to replace it with an insert eco-forest 16 kw granulated because they can be programmed, I would like to have advice on this ECOFOREST kiev 16kw insert are performance and 90%, reservoir 60 kg?
I asked whether it is powerful enough to heat a house 120 m2 knowing that the house is on two floors 45m2?
I asked whether he and efficient and economical?
Represented on and came to me and told me that I would come out with tons of granulated 2 years, my house and isolate glass wool of 30 cm in the attic and all the windows are double glazed somehow home keeps heat well,
I have retissance to take a pellet insert when I saw some comments that scare me and I would like to have the opinion of several people before committing myself knowing that the bill rises to € 8000.

Thank you all
Gregory
