condensate pump for 2 radiators in steam system

rhodebump Member Posts: 152
Hi everyone,

I would like to add two new radiators to an existing steam system. However, due to the room elevations, I would need to install the radiators in the ceiling for the condensate to be able to flow back into the system.

Is there another option such as installing a condensate pump? I did a search for them, but I did not find anything that seemed to fit my needs.

Thanks for your thoughts.

    I know there are plastic condensate pumps but I don't think they would hold up or would they?

    I presume, from the comment on the ceiling, that the spaces these radiators are supposed to heat that the spaces are on the same level -- such as the basement -- as the boiler?

    If so, have you considered the possibility of running a baseboard loop using the boiler water? If all the baseboards would be below the water level in the boiler, all you would need would be the baseboards, some piping, a small standard hot water heating circulating pump, and a thermostat to control the whole thing. There is often a tap on the boiler (may be rusted!) not far below the water level which would be your supply, and you could hook into the low level returns somewhere...

    That's a great idea! Thanks! yes, I have a tap for hot water, so I will look into that.
