Hey all I need some assistance with an issue I have next to zero knowledge about. I have a Weil mclain home oil burner, two zone (upstairs and downstairs), with no external hot water tank. The problem I have is that the burner makes enough hot water to last about 45 seconds if I run straight hot water from the kitchen sink. The hot water IS adequately hot for about 30 seconds but then begins to quickly cool down. Also, it takes the burner a good 2 minutes to kick on after the hot water has run nearly cold. The burner is about 15 years old, and the high/low thermostat is set at 180/120. The model number on the boiler says "68 boiler". Is this the proper setting for the high/low, and would raising tho low prevent the water from running cool so quickly and also allow the burner to kick back on before the water runs cold? Please let me know if u guys have any info that would be of help! Showers have been a nightmare for some time for obvious reasons!
