This way they were able to take hot showers and conserve water. I thought the book was great. It is just packed with information like that.
I used one of those for many years. I found it preferable to solar cos you can control the heat but thats about all.
On Raven, our previous boat, I went one step further, mixing the hot/cold in a bucket or head basin then dropping one of those cheap 12v shower gizmos you can but at any chandlery. We could use either kettle or solar to heat the water. Worked well and with some simple plumbing you could make it a more permanent installation.
That said, I love our tank heater shower on the current Womboat. Sheer bliss, other than (as per previous quite) having to run the engine to heat the water.
