The simple things make me happy. In this case it's a hot shower :)

Finally a hot water shower. I have a water tank connected to a pump connected to a splitter. one feed from the splitter goes to a 30 liter water heater, and then to the hot side of a thermostatic mixing tap, the other side of the splitter goes directly to the cold side of the mixing tap. The mixing tap is connected to a shower head. It might sound like a lot but it's actually very simple.
