2.5 Upgrade DTI to stand-alone heating

Hello, Does anyone know if there is an easy way for the Eberspächer heaters in the Omega 2.5 DTI to upgrade the whole thing to a stationary heating system? Do you know that of various vehicles with Webasto heaters. The Webasto devices then only have to be wired with an extra control unit so that the whole funkt. Then you can heat by remote control or timer or just ventilate. The latter is also not bad in the summer 🙂 Thanks already for your answers
