Backup heating for sunroom
Our electric bill was at an all-time high this month due to some exceptionally cold weather. We have a oil furnace and propane gas fireplace for the house. Also tankless water heater and kitchen oven run off propane. However we have a large sunroom, which we keep closed off most of the time, that is heated by an electric baseboard strip. Although this is set for 55, it would have to be the source of our high bills.
Does anyone have a suggestion for some other type of heat for this room. We keep it closed off because of our dog and cat who have free range of the rest of the house.
