Why is the GWP benchmark for HP Service Water Heaters so high (1400), especially compared to the HVAC one? There are already multiple CO2 based HP water heaters on the market that would have a GWP of 1 and the rest will be using R-32 or R-454b, most likely. There needs to be room to show the reduction to achieve the points, but 1400 seems high.
