We are on well water, cold water pressure is fine--hot water pressure is almost none existent. Our hot water is integrated through our furnace and it is 30yrs old. We have been in our house for 4 yrs and the hot water pressure was not an issue until the last 6 months.
Would it also effect how our dishwasher cleans, the top rack is never clean
Thank you

Your poor washer is unreated to the hot water pressure. The washer fills full not matter what the pressure or volume is. Probably an old washer with a failing top spray wand. No for the poor pressure, the pressure is likely just fine but a very reduced volume. I do not have much experience with combi bolier but Tom, Mark or Milo will be here later and can help with that. Have you ever flushed the system, it should be flushed at least once per year to get rid of sediment.

Hi all...

Ballenger's on the right track here...

Sounds like you have a TANKLESS COIL in that old boiler. After 30 years my guess is that the coil has gotten choked down by mineral deposits to a point that water is just barely getting through the coil.

To fix this you will need to do an ACID WASH (usually left to experienced plumbers) or you may even need to replace the entire coil. If coil replacement is necessary I would have you consider installing another type of water heating or storage device... The boiler sounds too old to go investing big bucks in coil replacement.
