| Output of selected heat pump at design temperature (-30C/-22F maximum) | 7.1kW |
| Percentage of demand load requirement produced by heat pump at design temperature (-30C/-22F maximum) | 124% |
| External backup boiler required | 6kW |
| Internal backup boiler required if using Alt Source tank | 7.5kW |
| Heating Demand Load | 20000 |
| Heating Demand Load Unit | BTU/hr |
| Selected temperature scale | Celsius |
| Heating Design Temperature | -25° C |
| Arctic heat pump required | 050ZA/BE |
| Comments | I’m looking for an air-to-water heat pump that can operate down to −25 °C and deliver approximately a 20,000 BTU heating load for in-floor radiant heating. The required supply water temperature will be around 100 °F. The system would also need to handle domestic hot water for a 4-bedroom, 2-bath home. I would appreciate clarification on the required equipment and components for this type of system. I understand the need for the outdoor unit and the radiant distribution system, but I’m unclear on where the heat exchanger is typically located — whether it is integrated within the outdoor unit or located in a buffer tank or indoor module. Thank you, Nicolas |
