This week the boiler's been acting funny. the heat won't come on downstairs, unless upstairs is like 73 degrees. usually we used to leave it on 70. and downstairs the same but now its not turning on. It sounds like it wants to and makes a buzzing sound, but then it doesn't do anything.
Also, last year we used to leave the heat at teh lowest temperature when we weren't home, and then turn it on when we get here. But I think its better to leave it at a stable temperature all day long, even if we are not home during the day. What is better? What do you guys do?
