Thermostat setting in hot weather (no AC involved)
Just bought a house with oil heat and hot water, no air conditioning (so it's not a heating/cooling system). I know in the winter, the thermostat should be set no lower than 55Ã¯Â¿Â½, but what about in the summer? I asked the oil company, and they say keep it at 55Ã¯Â¿Â½, but they want to sell oil, so I just don't trust that. So, what can I set my thermostat at in the hot weather seasons, to save money. (As for getting away from oil, which I would love to do for many reasons, is not an option at the moment). Thank you!
