Cons with solution

Shut off time

It shuts down after 20 minute of run automatically


This feature is designed to let it not get over heated or to prevent it from accidents. One solution is to turn it off and back on manually another solution is to attach a cheap repeat-cycle timer and set it to cut the power in 19 minute and turn it back on this will serve the purpose.

Low flow of water

Low flow restriction on the shower head can cause adjustment of heat on water for a long duration of use.


It is normal to have problem like such but if you remove the existing low flow shower head and replace it with a one with no flow restriction then situation will be better. Also some users have removed the low flow restriction from the shower head thus this problem has been resolved.

Long term performance is poor

Poor performance if installed at outdoor for permanent use.


This recreational water heater is not suitable to be installed for permanent use, and not for place above 5500 ft. It is better not to plumb into sinks, showers. Still if you have installed it for permanent use, it is suggested to be drained and put away when not used for long time.
