I recently installed an Emporia Vue with monitoring for the individual circuit my water heater is on. It captured the very significant difference in energy usage from replacing resistive heat with heat pump.
At the core it is the same thing like an AC unit or the cooler in your fridge. The technology itself is very reliable.
You need to check though if your house installation is suitable for it and that it has the appropiate size and can be placed in the right place outside.
It might make sense to combine systems. Maybe keep the gas-heater for hot water but run your heating on the heat pump.
