Hello All! I am new to this community but has already learnt a lot studying earlier posts. We live permanently in Italy since a year and are renovating an appartment of about 200 sqm.
I will try to beef up insulation a bit but there are also the questions of ceilingheight and how much insulation the italians will put in without arguing to much. There is no geometra involved and I haven´t discussed thermal analysis at all. Apicoltrice, your system seems to be similar to the one i am aiming for. I wonder about your size of house and size of accumulator. It seems sad that you keep returning to a cold house after a night out. I hope to have a 500 litres tank. Does your stufa produce hot air but no hot water? I also wonder if it is better to put the gas caldaia "after" the accumulator so that it will only heat water if it is not already hot enough from solar and wood energy. Or if would be better to have the caldaia heating the water in the accumulator as well. It seems to me that the first alternative would consume less energy if the caldaia is smart enough to handle the situation of heating only when water is not already the right temperature (also depending on whether it´s going to heat the floors or if it´s for the bathroom.
