system 2000 problem

kpg2010

I have a system 2000 ek1 that just went through about 65 gallons of oil in one week. I bled every zone, changed the limit switch, the zone valves seem to be working, the plate exchanger for hot water is clean. What else can I do?

How big is the home?

what size of boiler are you running? I would say if there is a boiler that requires manufacture trained repair techs it is the system 2000.

Domestic Hot water Leak?

Have you checked for a leaking faucet or pipe somewhere?

EK-1

with a Beckett AFG, the nozzle should be a >75 70 degree hollow. It is slightly overfired, but I'd be looking into a faulty oil line if if goes under the floor, and are you sticking the tank for those gallons, or going by the gauge?

I already checked the oil line for leaks. The proper nozzle is installed. I did notice one zone valve that when opened manualy TT makes on the board. I replaced it with a new one and it did the same thing. I didnt find any leaking hot water pipes either. I was going by the gauge on the tank.

nozzle size

are you sure it is not an EK-2? Keep in mind the pressure is 130-140 fuel pump pressure. If it an EK-1, you are slightly over firing the boiler. Having installed my first EK in 1984, the 1 has always been a max of .75. What are your combustion readings?

Gauge?

Using the tank gauge to measure oil use is not accurate.

Is the zone valve open all the time?

You said you replaced a zone head, and the new one does the same thing. Is the System manager light on the right side? May be a post-purge issue with the manager? The last zone, or water tank, should be post-purging. If that zone wasn't the last to call for heat, it shouldn't be powered

Excess fuel consumption

Maximum firing rate for the EK-1 is 1.00 GPH. Nozzle is  .85 GPH at 136 psi. Factory firing rate is .85 GPH, .75@130 psi. Please explain the zone valve situation. How many zones total are there? Which manager? If it's a digital are there any flashing lights? As previously mentioned, using the gauge is not an accurate way to judge consumption.

Don't read the Gauge

The tank gauge is not a good way to measure fuel consumption...especially if you were watching the first quarter of the tank.   If you want to accurately track consumption, an easy way is to install an hour meter that runs with the burner. 



Do your zone valves have end switches?  If they do, that sounds like normal operation to me.  If everything else appears to be in order...perhaps it is!  Have a System 2k guy check things over if you want to be sure.

system 2000

System 2000 doesn't normally use zone valves with end switches. The thermostats are wired to the manager. The manager outputs power the zone valves. There are exceptions which may be the case here. In any event that wouldn't make the boiler use that much more oil.

9 zones

Before I bled all the zones I noticed there was no pressure in the boiler. There was air in 2 zones for sure. Brought the boiler to 12 psi after purging and it doesnt seem to be running as often . I'm thinking air was the problem all along.

only if

you weren't getting heat, other than that, you'd use less oil. It would be up to temp without any effort. Where is the by-pass valve set? Should be fully open on that. Also is it a Classic or Digital manager?
