  • Why does my furnace drip bucket fill up so frequently?

    The water should stop flowing into the tank once it reaches the set pressure of the boiler. Turn the boiler back on and watch the pressure as it is running. An increase of about 5 psi should be normal.

    Boiler losing pressure problem and cures. Before we explain about your boiler losing pressure, we will give you just a little history. The combination boiler was invented in the mid 1800's but not in the way we use it for central heating or hot water today, it was only in the early 1960's that there was some serious inventions leading to what we have today.

  • What is the safe pressure for a hot-water-heating system?

    The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.
