A heating system is a mechanism for maintaining temperatures at an acceptable level; by using thermal energy within a home, office, or other dwelling. Typically, these systems are a crucial part of an HVAC (Heating, Ventilation, and Air Conditioning) system. A heating system can be categorized into central heating system or distributed systems, depending on their design and method of heat distribution.
Types of Heating Systems

Central Heating Systems: These systems produce heat in one central location and distribute it throughout the building.
This category includes furnaces, boilers, and heat pumps.[1][2]
Distributed Heating Systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters, fireplaces, and solar heating.[3]
Heat Pumps: They can be used for heating and cooling, transferring heat using refrigerant and electricity, making them more efficient than other heating systems.[4]
Efficiency and Environmental Impact

The efficiency of a heating system is typically measured by its AFUE (Annual Fuel Utilization Efficiency) rating. Higher AFUE ratings indicate a more efficient furnace.[5] Environmental impacts are a concern with heating systems, especially those that burn fossil fuels. The use of sustainable energy sources and energy-efficient systems is encouraged to reduce greenhouse gas emissions.
Future Trends

Advancements in heating technology focus on increasing energy efficiency and reducing environmental impact.[6] Trends include the integration of smart home technology for better system control and the use of renewable energy sources like geothermal heating.

How it Works — Heat Pump Water Heaters (HPWHs)
It's generally easier to move something than to make something. Putting that principle to use, HPWHs use electricity to move heat from one place to another instead of generating heat directly.
To understand the concept of heat pumps, imagine a refrigerator working in reverse. While a refrigerator removes heat from an enclosed box and expels that heat to the surrounding air, a HPWH takes the heat from surrounding air and transfers it to water in an enclosed tank.
During periods of high hot water demand, HPWHs switch to standard electric resistance heat (hence they are often referred to as “hybrid” hot water heaters) automatically. HPWH come with control panels that you to select from different operating modes 1, which include:
