My home is heated through radiators by a gas-fired hot water boiler. The system has lost pressure, and my upstair radiators won't get hot. Normally the boiler's pressure gauge reads about 20 or 22 psi, and now it is reading less than ten. I tried emptying the expansion tank, and it filled maybe half way when I opened the valve, but that didn't do anything for the pressure loss. The pump seems to be working OK. Any suggestions? We're getting cold!
