More progress on the pluming and electrical

That little tan pump you see next to the white drain pipe is for circulating the hot water from the hot water heater to the heater in the cabin. I'm using a thermostat in the cabin so when it turns on the heater it will also turn on the recirculating pump.
Here's a picture of the heater that I used.
In this picture I've installed the water heater and a more pluming
And the pluming done. Man there's a lot of stuff in this little space but it all fit.

I built a cover for the water heater

to clean it up a bite and for more storage on top of it.
