Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the Aegis A CO2 Heat Pump Water Heater. This estimator also includes instructions on modeling storage losses associated with water storage tanks per Lync by WATTS' available products. This estimator is applicable for the 250, 350 and 500 models.

Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the Transom Heat Pump Water Heater. This estimator is applicable for the V105, V210 and V420 models.

Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the ECO2 CO2 Heat Pump Water Heater. This estimator also includes instructions on modeling storage losses associated with water storage tanks and swing tanks per ECO2's available products. This estimator is applicable for Gen 1 through Gen 5.

Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the Daikin Mega-Q Heat Pump Water Heater. This estimator is applicable for the RXHWQ120MQTJA heat source unit model paired with the BWLP120TJU cascade unit model.

Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the Ice Air ccHPWH. This estimator is applicable for the 275-D-B, 275-S-B, 550-D-B and 550-S-B models.

Phius has made the decision to place a pause on requiring DOE Efficient New Homes Multifamily Version 2 certification as a co-requisite for multifamily projects.
