My house is outfitted with in-room electric storage heaters (installed in late 90s). The model is Stiebel Eltron ETS 208 (and 308). Those hail from the age where night-time electricity rate was relatively low, so they "accumulate" energy overnight and then release it over the course of the day.
One of the heater units has just started sparking and burning inside (not sure whether due to shortage or something else) - we were lucky to be home and cut power immediately to stop the fire/smoke. Given that the units are ~20 years old, it might be a good sign we have to replace them.
Question: what would you recommend as a replacement for such units? My understanding is that this "smart" electricity usage is no longer relevant, as the rate is the same for night and day, so maybe the new standard for such heaters might be vastly simpler... Recommendations are very welcome.
UPDATE: Closing the loop. I've ended up picking a plain vanilla baseboard heater (more specifically, Dimplex 60" 2,500W one). It is yet to be seen if it has any notable effect on my power bill. One interesting thing about it is that it supports some kind of wireless control protocol called CONNEX. There aren't too many thermostats that support it but there are still some. If I like what I see with it and end up using similar model to replace the remaining ETS heaters, I will most probably get such multi-zone thermostat as well.
