Customer has normal pressure on the cold side, but hot side is weak, this is happening at all the fixtures. The hot water comes off the furnace (no hot water heater). Can anyone offer a suggestion as to what could be slowing down the hot water in this situation?
Thanks, Mike

suspect water inlet pressure regulator on the boiler...

UH?Now I don't know much about boilers.But the water pressure for the domestic hot water pressure needs to be the same as the cold water. Otherwise you would never get any hot water flow when you have a mix of hot and cold selected..

About three days ago, somebody had the same problem. You suggested change rubber or plastic washers in the faucets and valves because that was causing the slow pressure. This must be the same. The other reason was sediments in the water heater. But, I don't mean to change the subjet, a water heater from a furnace? Like the kind to warm the house?
This is ALL fixtures so that it has to be something common to all of them.There is one (or was) "furnace" that also heated the domestic hot water. Lennox Complete Heat. By the dictionary a furnace is just a device that produces heat. But in common uses it's more often used for hot air systems, but really not limited to it..

Pressure or flow rate? They can be confused easily.
Fill a one qt pan and time both cold and hot. I am betting you/they mean flow rate.
Don't know how to fix it, cuz I have the same issue sorta..but an ele heater.

The hot water comes off the furnace
Yup, that's the problem.
Since a furnace only produces hot air.
Perhaps you should source the hot water from the boiler.

Check all valves that lead to & comming from the hot water source. Make sure that they are fully open if they are ball valves & full open & backed off an 1/8 of a turn if they are gate valves.
How old is the piping?
What is the pipe made of?
I'm sure it is a "flow" problem & not a "pressure" problem.

If I understand correctly, you have a boiler with a tankless coil. The coil needs cleaning or replacing.
if it is set up like a boiler, boilers usually opperate at about 15 psi
