Final answer:
Type 1 systems in HOT2000 refer to methods like electric baseboards that use radiation, while Type 2 systems like gas furnaces generate heat through convection. Supplementary systems, such as wood stoves or heat pumps, provide additional heating and are often more efficient.
Step-by-step explanation:
When modeling heating and cooling systems in HOT2000, different types of systems are categorized based on how they generate and distribute heat. Type 1 systems typically refer to electric baseboard heaters that run electrical current through a coil of wire to produce heat through radiation. Type 2 systems, such as gas furnaces, burn fossil fuels like natural gas to create heat through convection. Supplementary heating systems like wood stoves burn wood to provide additional heat when the primary system may not be sufficient. Supplementary systems can also include heat pumps, which operate on the principle of heat transfer and are particularly efficient since they move heat rather than generate it by burning fuel.
