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

ventilation systems are defined as either a mechanical whole-house ventilation systems or as
supplemental components.
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.

-manufacturer name
-model number
-supply and exhaust flow rate
-fan power (W) at 0 °C (32 °F)
-fan power (W) at -25 °C (-13 °F)
-sensible recovery efficiency (SRE) at 0 °C (32 °F)
-sensible recovery efficiency (SRE) at -25 °C (-13 °F)
bathroom fans:
-manufacturer name
-model number
-exhaust flow rate
-fan power
range hood fans:

If utility fans are not part of the whole-house ventilation system, collect the following information for
each utility fan:
, -fan's function as supply, exhaust, or supply and exhaust.
If utility fans are part of the whole-house ventilation system, collect the following information for each
utility fan if documentation is available:
-manufacturer name;
-model number;
-unit's function as supply, exhaust, or supply and exhaust;
-supply and exhaust flow rate(s)
-fan power
- ducting configuration:

-annual energy consumption shown on EnerGuide label
Identify the types of systems that can be modelled in the heat/DHW combination screen.
A) Propane, gas and oil, and storage tank water heater combo systems (condensing or non-condensing);
B) Gas and tankless water heater combo systems without a secondary storage tank (condensing or non-
condensing);
C) Propane and tankless water heater combo systems with a secondary storage tank (condensing or
non-condensing);
D) Combo systems using an oil boiler. - ✔✔A) Propane, gas and oil, and storage tank water heater
combo systems (condensing or non-condensing);
How should the Energy Advisor prepare the HOT2000 file for submission to the service organization?
A) The energy advisor models the house in HOT2000, saves the calculations as an "h2k" file and submits
the house evaluation file to the energy service organization;
B) The energy advisor models the house in HOT2000, saves the calculations as an "hse" file and submits
the house evaluation file to the energy service organization;
