They are instant on or at least the brand "Paloma" which I had was. It was NOT a good option as it went hot and cold on me.TEHAMA said:Thank you. One more question though.
Can you turn it off when not in use? Seeing as there is no tank keep heated. Unfornuately I do not think I have space for a second and would not wish to upgrade this rental. The EEMAX box is small and appears to be easy to remove and carry to my next apartment.
