I love the spirit. We need people making demands like this to move the needle. It's totally insane that it's still possible buy ornamental gas fireplaces that don't even heat the space.

Or that we use propane heaters on patios to heat the outdoors.

Re banning replacement has furnaces... maybe tie it to the scope of work. Like if your furnace breaks down in the winter and you're just replacing it that's one thing, but if you're actually renovating that's something else.
