The analyses differ slightly; in the NOAA version, the 2010 temperature was 1.12 degrees Fahrenheit above the average for the 20th century, which is 57 degrees.
二者的分析略有不同。 NOAA的版本是2010年的温度比20世纪的平均值（57华氏度）高1.12度。
This version would heat up about 3 to 4 times slower than that, but it can easily heat up the 45 gallons to a good shower temperature by noon or so.
本设计版本的加热时间是它的3-4倍。 但是到了午时它能够加热45加仑的水，够你淋个不错的热水浴。
The version with heating, the heat loss is minimized, heater temperature required is reduced greatly.
采用对版吻合加热，将加热器的热能损失减至最少，加热器的所需温度大为降低。
