Ugh that's awful for you with the house.
Our gas Fireplace crapped out when it was coldest and we are waiting on repairs. We have baseboards as a back up but they aren't keeping up and I'm not looking forward to the hydro bill when it comes.
It's nowhere as bad as your situation by any means but we are glad to have them.
I bought electric blankets for the bed and couch this winter based on a gut feel in November and with how warm it's been this up until this point the gf has been right that we didn't need them. That was until this cold snap. Bloody thankfully to have them as they can't be found in the stores now.
I hope those leaks get sorted out soon!
