I have a tankless hot water system in a New Yorker oil fired boiler. The system is about 12 years old. The hot water coming out of the faucets is not that hot. The boiler shows a temp of 190 but a measure of the hot water at the hot water pressure release valve is 130. Could there be buildup inside the piping of the tankless unit? The boiler was justed cleaned and tuned and is considered 80.5% efficient. Any ideas?
Thanks

Check to make sure your boiler is filled all the way up, If the tankless coil is not surrounded by water, it wont heat up..you may have a bad thermometer, and / or Aquastat

Gas and Oil Home Heating Furnaces
air condioner stopped cooling

on Aug 25, 2000

Have an AprilAir cooling system. Last year replaced thermostat with a Honeywell programable. Been running fine until last week. We noticed that each time the unit turned on or off you could hear a slight "tweek" sound at the thermostat unit. Two days ago the cooling stopped. The fan and the outside unit run constantly, but no cold air. Shut it off. Can anyone help?
