Low hot water pressure

Hi,
WE have an old oil hot water boiler with the hot water pressure diminishing as time is passing. We are at the point now where it is hard to take a decent shower the hot water is so slow! It takes over 30 minutes to fill the washer with all hot water. We have a well (not main water) with Excellent cold water pressure. The heating is internal in the boiler. We plan on redoing the entire system in the next year, but are there any suggestions to help us through the next few months?? Thanks for any help - my wife is getting very cranky.......

Low H/W Pressure

Often the coil can be cleaned by pumping acid thru it. This is not a job I suggest a homeowner do.
There are risks associated with this cleaning which range from the coil clogging completely to failing (requiring replacement). The replacement of the coil can involve risk as well. Once in a great while, during the removal of the old coil the bolts will snap off & in the worst case the boiler could crack. I've never had a boiler crack but have had to drill out the old bolts & rethread the holes where they went.
All of this is not meant to scare you off from the idea of getting the coil cleaned but just to give you a heads up as to what could happen. In 20 years of doing this, I've had one plug completely & one fail.
