I have a eko 40 with 1000 gal tank . It has been working great. for the last few firing's i have had to bleed air each time for the pump at the eko to run. this morning i woke to a cool house with no hot water. the tank in the garage reads 165. the pump in the house that draws from storage was running but cold so I isolated it to check for air lock ,some air came out but in the mean time I spilt water on my relay to the oil burner , now trhe pumps come on for the zones but the burner will not?
