What is a central heating heat exchanger?
Simply so, what does a heat exchanger?

Subsequently, question is, what is the heat exchanger and what is it used for? Put simply, a heat exchanger is a device which transfers heat from one medium to another, a Hydraulic Oil Cooler or example will remove heat from hot oil by using cold water or air. Alternatively a Swimming Pool Heat Exchanger uses hot water from a boiler or solar heated water circuit to heat the pool water.
One may also ask, what are the symptoms of a bad heat exchanger?
3 Signs Of A Bad Heat Exchanger
- Cracks. A cracked heat exchanger is one of the most basic and common symptoms, and also often the most drastic sign of a damaged heat exchanger.
- Discoloration. Sometimes a cracked heat exchanger has cracks that are simply too small and thin to be directly observed.
- Odd Furnace Flame Behavior.
What is the difference between a local heating system and a central heating system?
The main difference between central heating local heating is that with central heating, the heat generation occurs in one place, such as a furnace room in a house or a mechanical room in a large building.
