Final answer:
Applying procedures for modelling furnaces and boilers includes using defaults in HOT2000, following manufacturer instructions, consulting a professional, or referencing neighboring systems. Northern European homes remain warm without heating due to superior insulation and heat retention. Small temperature differences between inside and outside improve energy efficiency.
Step-by-step explanation:
When applying the procedures regarding the modelling of furnaces and boilers, several options are available depending on the specific requirements and resources:
- Use default settings in HOT2000: This is a starting point for initial modelling. HOT2000 is an energy simulation and design tool for low-rise residential buildings.
- Follow manufacturer instructions: Manufacturer's guidelines provide specific details necessary for the correct setting and operation, affecting the efficiency and safety of the system.
- Consult a licensed professional: This ensures proper installation and adherence to local codes and standards. The professional can also provide customized solutions based on the house's needs.
- Base it on neighboring houses' systems: This can provide a contextual reference, but may not be optimal as every house has unique thermal characteristics.
In Northern European nations, homes built without traditional heating systems remain warm due to superior insulation, which minimizes heat loss. An explanation for warmth, even when residents are not home, could be the retention of heat due to such insulation paired with passive solar gain or internal heat sources such as appliances. Energy efficiency is increased when there's a small difference between inside and outside temperatures, as this reduces the rate of heat transfer, explained by mechanisms like conduction and convection.
