I have a 6 year old setup with a oil fired Weil-McClain boiler that is also a tankless water heater and it has a power vent exhaust.
I have hydronic heat and even though the heat isn't used in the summer, of course the boiler is running for the hot water.
I am wondering if this setup is all that efficient in regards to oil use. Would I be better off with a separate boiler and hot water heater? or an indirect water heater?
My motivation here is that I would have the boiler replaced with a Boderus direct vent so that I can get rid of the noisy power vent. If there were additional heating oil savings that would help motivate me too...plus I figure the existing boiler is still worth something since it is only 6 years old (WGO Gold I think).
I live in upstate NY if that helps. Thank you in advance for any advice.
