All DHW data collection
manufacturer (only required when the efficiency is known);
model number (only required when the efficiency is known);
energy source;
equipment type ( for heat pump water heaters, indicate the type as integrated or add-on;
tank volume (L, gal. or U.S.gal.);
efficiency: Depending upon the type of equipment, the water heater performance can be defined by energy factor (EF)5 alone or by a combination of the following specifications:
- standby heat loss (Btu/hr, W or %/hr). If unknown, consult Natural Resources Canada’s searchable product model listings;
- thermal efficiency (Et %); and
- input capacity (Often an electric DHW heater has more than one element; use the capacity from the nameplate of the largest single element.).
Tankless
If it has a buffer tank more than 7.6 liters, record that too
-
Conserver tank
Conserver tank: Applies only to electric storage tank water heaters with reduced standby losses. Conserver tanks will typically include those with a minimum insulation of RSI 1.8 (R-10), typically foam. If an insulated blanket is present, make note of its nominal RSI/R-value. A conventional electric storage tank water heater with an insulated blanket is not considered to be a conserver tank.
Itegrated HP
Integrated heat pump water heater and add-on heat pump water heater: These types of water heaters use an integral or stand-alone air source heat pump to extract heat from the air and transfer it to the stored water. These units typically look like an electric tank type water heater with a top mounted or adjacent refrigerant compressor and evaporator coil.
