a sealed system is a bit like the system you have on a car radiator.the water is introduced from the mains water and is pressurized(usually to 1.5bar). this water is then circulated by a pump.the benifit of this is that there is no water loss from the system and air cannot enter the system so you dont get air in your radiators or contamination from the atmosphere. it is usually found with a conbination boiler and is a far more efficient system than the old gravity fed systems...probably confused you more!!

I'm not sure I can be much help. But we have a central heat pump system. It has a sealed fan unit in the attic. I know it cannot be lubricated because of this.

The system itself is sealed - as in you dont have an expansion tank in the loft and you fill your system direct from the mains.

Ringaloon and Starlet 10 are the correct answers. We do not use steam heating for domestic purposes in the country.

a sealed system is simply saying the compressor is a sealed unit i.e. no access.

heat is used to make steam steam is used to heat a heating coil or rad steam condenses to condensate and is carried back to the boiler for makeup water hence a closed loop system

If it is water heating it means you don't continually add new water,you reheat the water in a closed loop.If it is referring to combustion it means the air for the fire to burn is piped in from outside not drawn from air inside the building.
