Legalett in slab radiant heat vs heat pump

 I am looking at having Legalett engineer a raft slab foundation for our new build. My question is regarding also installing their in slab radiant air heating system instead of a ducted heat pump for the heating needs of our home.

The plan is to have a well insulated and air tight envelope...would the Legalett heating system be worth the cost when considering that the cold weather heat pumps available today can be up to 3 times more efficient per watt than radiant heat generated by an electric heater,which is the heat source for their radiant air system. Also the heat pump can perform as an air conditioner for the warmer months. Have you run the numbers to compare the installation/operational cost of those two methods for home heating?
