Hello! I wanted to know if it is possible to place a water heater without having a water tank. Developing; It is a small house in the countryside to which we go twice a year. We had thought about installing one of those gas-fired gas heaters that have the shower incorporated, or know that the water heater would only be for the bathroom. Will it work without a tank? . I clarify that there is no electricity, before I recommend something electric. In some post I read that a person was told yes, but they were talking about a hot water tank, and they recommended its use at night which is when there is more water pressure. THANK YOU!!

you need if or if a tank because the "JACK" and even the irony of this device is that by means of a RESISTANCE or gas you heat a large amount of water "inside a reasonable tank" and then this you will use it hot, no It makes sense to heat a small area if you are not going to "GIVE TIME" for cold water to warm up and get to you as you want it ... so IF OR IF you must have a tank, obviously there are small sprinklers with resistances SMALL INCORPORATES that heat in a brutal way and are electric but still have a very small "internal" tank in which time to heat the water. pd = ANOTHER would be to invent what you want with a 2-inch tube for example 15 cm on both sides with reducers to 1/2 inch or 3/4 inch and right in the middle of the 2-inch tube PUT A fixed FLAME that heat that tube and test the results, that it may work I do not discard it, that if the tubes must be iron.
