A back boiler is a boiler which supplies a central heating and hot water system and is fitted into the recess of a fireplace.
A boiler functions by boiling water to a steam, which rises upwards. Keeping the hot water tank above the boiler helps keep the hot water hot, as well as allowing the steam to carry itself to the tank, instead of the hot water tank producing steam feeding back into the boiler.

An electric water boiler is a small appliance used to boil water. This can then be used for hot drinks or in a recipe that requires boiling water. An electric boiler is also helpful if the water coming from the tap contains contaminants, because boiling the water will eliminate them.
The hot water usually goes to a storage tank. The PRV goes there, near or at the top.
They have a recirculating system that keeps the hot water flowing 24 hours a day through the piping system and back to the boiler.
So the steam can rise from the boiler to the hot water tank storage
