Thermal storage heating

I would like to install a surface storage heater in my half-timbered house soon. However, I have no idea which storage core is the best. The options are chamotte, ceramic, or evolit. Have you had any experience with these? I am very grateful for any information and suggestions! Regards, trend.

Hello,

I want to install a surface storage heating system in my half-timbered house soon. ..

An electric heater is probably a bit off the mark :( At best as a small supplement in the bathroom or similar. Unless you have a passive house, then it might work. With higher heating loads, it will be a money pit. Regards
