First year for the boiler, everything going well (if I use seasoned wood that is), however tonight for reasons unkown the water pressure is not holding consistent. The fire was down and the temp was a little low, so as I built up the fire and the water temp was climbing, i glanced at the psi gauge and it was almost at 30. So I then pulled the release valve to lower the pressure down to 20, and had to keep doing it until the temp reached the target of 180 degrees. Along the way, at one point it dropped down to zero and then back up. It seems to have stabilized around 20 at this point, but it is still worrisome. I thought I would check here to see if anyone has any ideas or has experienced something similar. I will be sending email to Dale tonight...
