u/mullethunter111 my square footage is close to 3600.

That is great input. The fireplace is not sealed. I recently brought a thermometer that is a temp sensor option. That is something I can start with for sure. Thank you for your input.

u/tehsecretgoldfish you ask a great question. The windows in the house are old. They are wood windows and most of the handles are broken. That is for sure another expense coming.

No, I did not. I would not be having this problem today if the extra zero was not real.

I do have insulation. We try to keep the temp as low as we can but I have a small kid in the house who does not do well with cold temp.

Thank you very much! I guess I can get more information about insulation from an auditor once I am able to get an appointment. Do you have experience with this kind of work?

Hello! Sorry! I did not mention which city or town for privacy reasons. my Reddit name is too specific to what I do. I am reading the information in the link that you shared above. It looks the same as what National Grid gave me right now. I will be sure to keep doing more research tough. Perhaps I am missing some useful information. Thank you for sharing.

u/Linux-Is-Best thank you for this information. I think I should drop the solar option as it has too many complications. Great input though!

u/ipalush89 thank you for your input. Pellets stove were suggested to me as an option as well. I have to mention that the lower level of the house has a fireplace that I never used.

When I was discussing about the pellet stove with other relatives, it was suggested as a good option because the lower level of the house is an open place which will facilitate the distribution of heat at that level.
