Cons with solution

No Modulator available:

This unit has only on off switch no regulator to set the temperature as high or low.


This unit has this big issue of no modulator, only on off option. You can buy a regulator extra for controlling. Otherwise you can use cold water faucet to work as a mixer; for example if you are using only the hot water tap and supply water temp is 55 degrees, Your heater water if has 70 degrees than the resulting temperature will be 125 degrees. Again in winter time when supply water temperature drops to 30 degrees, the resulting temperature will get 100 degrees.

Need pro help for installation

The unit need 240 volt and to add 240 volt to the unit normal DYI skill may not be adequate, you might need an Electrician.


More electricity means warmer water. So as you signed up for hot water you need to give out this responsibility to an electrician or you can do it yourself if you have prior experience. Plumbing on the other hand could be done by anyone. Bottom line is-It is a very easy installation processes no need of a pro unless you have some DYI skill.

If you have a kitchen or a Basin need with hot water 24/7 than this is your thing. It gives instant hot water for indefinite period of time. In small apartment it may serve the purpose of a whole house heater but I do not recommend it for showers because of the low GPM and shower heads generally the highest GPM (1.5-2.5 GPM). SO if you are a firm believer in energy conserving theory and want to investing a system that guarantees hot water at first touch than this one is your catch. However .5 GPM makes it a dedicated water heater for a single application.
