I have a Trianco oil burning furnace. It’s a forced hot water heating system that is 9 years old. Within the last two-three months, the hot water pressure for taps, showers, washing machine, etc. has been decreasing to the poing where I can’t even use one of our showers – there just isn’t enough pressure. Any idea what the problem might be? The furnace has been cleaned every couple of years.
From the description you have given I would suspect that you have a restriction within the heat exchanger unit at your heater which is blocking the flow coming out of it to your taps etc. It could just be that the unit is getting full of grit and suchlike – call your serviceman to come check it out for any blockages. Hope this helps.
