Hi all, We just moved into a house that has a Utica Starfire 3 Oil Boiler feeding baseboard hot water heat. The boiler also provides hot water that is mixed before feeding to an electric hot water heater. I had the boiler serviced yesterday after moving in, and the tech told me that he didn't think my system was configured in the most efficient way and he suggested a change. The boiler has 4 zones with separate circulators. One zone is controlled by a Honeywell relay on the side of the boiler which has the aquastat (set to 160 deg low, 180 deg high, 10 deg offset), and then there are 3 separate Honeywell relays for the other three zones. He pointed out that these relays are unable to call for heat and just start their separate circulators. He then suggested replacing the relays with a 4 zone Taco relay board so that all zones would be able to call for heat (but leaving the relay that has the aqua stat in it), and then this would allow us to set the low point much lower (he suggested 110 deg, which looks like it is the lowest setting on the Aquastat; I don't recall if he suggested lowering the high point as well) and save significant fuel (especially in the summer when all the boiler is doing is providing preheated water to the electric hot water heater so anything over 120 is unnecessary; I asked about just turning the boiler off in the summer and he suggested against it saying it could cause leaks in the boiler). I had another contractor out to get a second opinion today, and he said he understood where the first guy was coming from but wasn't sure that it would save us enough money to make it worth the costs of the work, he also wasn't sure that 110 deg was warm enough to prevent leaking. As a side note, he also pointed out that the boiler is probably oversized and would typically be intended for a house about twice the size of ours. Note that unlike the first person who was a service technician, this guy was a salesman. Does anybody have any suggestions about what the best path is here (do what the first guy suggested, do nothing as the second guy was leaning towards, or some other solution)? Trying to learn as much as I can about the system as well, as I had a heat pump in my previous house so I am completely unfamiliar with boilers. Another piece of info that may be relevant is that I am also planning to replace the old school Honeywell T87 thermostats with Ecobee3 stats. Thanks for any help anybody can provide!

I connected today 3 water heater 10 gallons. 120 v can't get the hot water . Tried temp .change nothing I tried conecting 220v and nothing can someone explain
