-   My pressure relief valve keeps leaking when system pressure is above 20 PSI. I tried lifting it quikly and releasing it to clean it but I can't get to stop leaking.
Should I change the pressure relief valve? or should I change my old expansion tank to a more modern pre-pressurized tank? -   Gio123
Check the pressure guage. Typically the pressure in a water boiler should not be more than 20 psi. If you are approaching 30, the relief valve is doing it's job. I would replace or adjust the automatic water feed if the pressure is high. Always replace the boiler relief valve. Tap on the expansion tank, it should sound hollow. Replace it if it is full of water. If you have one of the old expansion tank that has no bladder in it, drain it.

I installed a 1000 watt four foot long Farenheat F2544 baseboard heater in my outdoor workshop. But it's too small for the space. I calculated that I probably need 2000 watts to heat my space. But I do not have enough perimeter space to mount additional heaters. My question is can I safely mount another identical 1000 watt baseboard heater directly above the existing one as long as I leave sufficient space between the two heaters? If so, how much space is required between the two heaters?
