Due to some breaking changes in v2.0.0, the request in this ticket is not longer valid, but with some slight tweaks to align schemas, this bug is now resolved in our development environment. Note that in the waterHeatingSystems object, systemType is a required field and fields energyFactor and uniformEnergyFactor have been renamed to efficiency and efficiencyUnits.
