A few years ago I built my kitchen, within the room are two radiators. I enclosed them with units and topped with oak worktops. I added a vent in the kickboards and in the worktop to allow heat to circulate. I'd like to improve the heat being moved because the units and tops are huge heat sinks. I'm not really bothered about warm cutlery, and my wife would much prefer the heat to be around her.
I had the idea of using pc fans underneath the radiator to force air through, what would be the best way to power the fans.
I just happened to find a product that does exactly this on youtube called speed comfort but they are out of stock every where.
