- EER cooling
- 3.3
- COP heating
Why this unit
Ordinary hydronic heat pumps top out around 130°F, which is not hot enough for the baseboard radiators older houses were designed around. The 504W11 uses OptiHeat vapor-injection technology to push leaving water to 145°F, so it can replace a boiler without touching the radiators.
Available in 4 and 5 ton sizes, backed by the same warranties as the rest of the WaterFurnace line.
Best for: Houses with baseboard radiators or older radiant systems on a boiler.
- Up to 145°F leaving water via OptiHeat vapor injection
- Drop-in boiler replacement for baseboard and radiant systems
- 4 and 5 ton capacities
