Is there a similar model of GE Dishwasher that has similar feature, but also includes an internal water heater?

Hello - Thanks for reaching out. The Dry Boost feature this model offers is an innovative new drying option that targets hard-to-dry items like plastics. It significantly improves drying performance, providing up to three times better drying compared to a Heated Dry option. We hope this information is helpful. Take care. -Don@GEAppliances
