In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
We have just converted from oil to gas on our one pipe steam system. The new burner is short cycling, sometimes running for just a few minutes at a time for no apparent reason. When the thermostat is boosted a couple degrees the boiler cycles in 20 minute intervals before reaching temp. Radiators are not filling with steam completely even though the furnace has run for hour and the last radiator never gets heat. The radiators are vented with vari valves and are open, we can here the air escaping but the steam isn't following. The installers replaced the gortons on the main lines. The installer came back and said because the house is large (a 2 family with 16 radiators) the pressuretrol needs to be set higher than .5, even though it contradicts everything Dan says, they raised it 1, with no improvement. I hope someone can help. We were hoping that replacing our 25 yr old oil burner would provide better comfort and money savings, but so far it hasn't happened.
