I have heat

[somewhereinusa]

I have finally got the Espar Hydronic10 boiler going and now have domestic hot water and the first loop  of heat that goes to the front and the original heater core with an added core for driver feet.

Temperature drop in entire loop is only 4 degrees with outside temp at about 70.  Temp coming out of boiler is about 106. Does anyone know what the outlet temp should be?  The only reference I can find is that overtemp shut down is 115, but no reference as to what operating temp should be.

Thanks,
Dick

On the 12 the shut is @ 235 F degrees (115 C) the operating range with the standard switch is 158- 176 degrees F the hotter switch is 178-198 degrees F I would think the 10 and 12 should have the same temperature range maybe not

Great!
But I think it's the wrong time of year for heat unless your a reptile!

I may very well be, I tend to not do much when I'm cold. I figure now's the time to work on it while I'm still mobile.

I finally found the temps for the 10 If I'm reading it right the unit cycles down at 162, if it gets to 185 it shuts down, then restarts at 145.
I'm not getting anywhere near that.  I'm not too sure of my readings. I'm using a infrared non contact tester that seem fairly accurate. I'm measuring the temp of the pex about 8 inches from the boiler and it cycles between 125 and 115, which to me is a bit on the cool side. I have also noticed that if i measure the temp at any of the brass fittings it measures about 8 degrees cooler than the pex line.  Why is that?

Somewhere - the difference in temp between Pex and Brass is the different emissivity of metals - put a piece of electrical tape on the Brass and then shoot the temp - HTH

P.S. Is there not an adjustable thermostat on the unit?

They make a nice soothing powder for that.
