The manager hasn't been a problem for me. In fact on unit number 1 I bought the card that bypasses it in case I had an issue. It's never been used.So I narrowed my search to a biasi b10 or a system 2000 ek1.I like them both. My oil guy prefers the system 2000 he likes the way they power vent better. I thought a smallest biasi the b10-3 would be a nice little boiler. I just want two zones and they make a direct vent kit but I would have to enlarge the existing hole in the foundation. I'm looking ahead for the long hual so longevity is the most important to me. I get a little spooked about the energy manger on the system 2000 hate to have costly repairs.
I might consider a heat pump water heater, vs. the indirect, at that cost.I do not think anyone will say bad things about the system 2000, although two folks reporting cooked control boards would have me install a dedicated surge protection device on the boiler rather than depending on a whole house unit. The big issue is they cost more to install up front as there has to be a hot water maker (Amtrol Boilermate or equivalent) which retails for around $1000 probably $2,000 installed. Since they sell direct to dealers with assigned territories I expect that also ups the cost.
I read that the gas pipe should be bonded to the electric system grounding wire. It was something about getting the electric charge away from the gas pipe and not using it as a grounding point IIRC. It was 11 years ago.i am a siemans murray guy. watch your price vs. clamp voltage for whole house surge protection. or i wish they would call it spike protection. they can range from 40 to thousands of dollars each. for a few hundred square d makes good ones. then for added protection use good not cheap plug in units where needed. badlp what was this about bonding the gas line? some of the inspectors i run into tell me to pull it off the gas line.
That's pretty much what I have . . . well except that it's a Pennsotti and has three zones and is plumbed for a future fourth zone if I want . . . but I also have the Riello burner and sidewall venting.I do like the biasi's they seem simple and easy maintenance, We'll see. I think I'm going g to leave it up to my installer. I thought a biasi with two zones with a rellio buners set up with the direct vent kit would be a nice setup because I have no choice other than sidewall venting
To tell the truth I always thought they were Italian . . . but now I think you may be right -- either made in Maine or in Canada. I think I may have learned something new today. All I know is it's been fantastic and a huge step up from the old oil boiler.pennsotti those are made in maine right? Do you have a power venter or is it set up as a direct vent ?
