Hot water starts hot but gets cold quickly.

I have an off the wall question. Does your boiler have a minimum flow device in the coil that causes the boiler to only come on above a certain cubic feet per minute of water flow, like a tankless water heater does? Maybe you have a low flow shower head that has a flow restrictor that keeps the flow at 2 gallons per minute which is below the minimum flow rate of tankless water heaters. Try removing the shower head and see how long you have hot water.

i didn't read far enough to know if someone suggested flushing the water heater out? it is not hard. you can even do it w/o turning pilot light off if you've help.

i think this is considered yearly maintenance.

hope you fixed it!
