I have an old American Standard A-5 Oil Boiler. No. A504, Series 2BJ2. There are two thermostats on it. I assumed one was for hot water and the other was for heating (Baseboard Heat). One thermostat is set at 120, the other at 160. I've had it serviced many times and one guy upped it to 160 from 150 (The hotter the water, the less it takes to heat a room). What I found out is the water temperature at my faucet is 160. Since I've had this boiler serviced by many 'experts', I assumed what they are doing is correct. Is it possible they are setting the wrong thermostat. Or are they correct and I have to live with very, very hot water at my tap. What would the other thermostat be for. I have searched online for manuals for this boiler and have not found anything. The cold season is approaching and any help would be appreciated. Thank You.

Its come to that time of year when the boiler gets fired up again, I have a VCW BG 242 EH, the hot water works fine as it has been all summer. The problem is that the central heating will not come on, I have checked the thermostat and it seems to be working, I have tried running the hot water and then switching on the heating and then switching off the hot water, this didn’t work either, the pump has been checked and is working, the radiators have been bleed, has any one any ideas?
