correct answer ✅HOT2000 User Guide
7.15.1 to 7.15.3, Appendix F
Efficiency Rating type:
select energy factor or uniform energy factor, if unknown, select
energy factor
If the Energy Factor radio button was selected, then select User
specified to enter the assessed Energy Factor. Alternatively, select
Standby to enter the efficiency by Standby Heat Loss, Thermal
Efficiency and Input Capacity. Data must be entered into all three of
these fields to define the efficiency by standby heat loss unless the
Energy Source is Electricity. In that case, the Thermal Efficiency is
automatically set to 98%. If the efficiency is unknown, use the
HOT2000 default.
For heat pump water heaters only integrated heat pump water
heaters located inside building envelope can be modelled in H2K
Do not use Tankless heat pump or Heat pump for modelling

correct answer ✅Technical Procedures
3.5.11
ventilation systems are defined as either a mechanical whole-house
ventilation systems or as supplemental components.
, EA Exam Questions & Answers (Grade
A+)
whole-house ventilation system circulates air throughout the entire
house
Ventilation equipment that operates independent of the whole-
house system is considered to be a supplemental component.
Supplemental components are localized systems, such as kitchen
and bathroom fans.
