I’ve read hot side temp estimates for the DPF cooling system that range from 800-1200 degrees F so I don’t think there will be a problem with keeping your current steam heat setup if you aren’t running any turbines etc with it.
And as a bonus you still get much cheaper electricity… so perhaps in the future you might be able to afford incrementally switching out the steam units bit by bit as time goes on and replacing them with electric heating units that might be cheaper and easier to maintain.
