I was looking into ways to save money with the increasing price of oil. I was originally looking into replacing my oil boiler with an electric boiler but have decided that it is a bit more expensive than I'm willing to pay. I'm now considering adding an indirect tank to my oil boiler. Can anyone explain how this works to me (like I'm a two year old )? Also, I was told I can expect around a 25% savings with this, is this about right or is it way off? I'm trying to determine whether it makes sense to add. I'm also going to replace my thermostats with programmable thermostats. What sort of savings can I expect with these thermostats and what temperature should I be programming them to drop to when not at home or sleeping?
Any help with this would be appreciated. I just want to make sure I'm not just falling for salesman tactics.
