| I'm looking for an outdoor tankless water heater, with a fixed temperature output, and low voltage (like the 2 D-cell ignition). I currently have an Onsen portable outdoor unit with its own temperature and flow dials. The hot water output goes to a standard shower control valve (also with a cold water feed). The problem is when we adjust the temperature using the shower control valve, the temperature wont adjust properly because the Onsen unit doesn't like when the hot water out is restricted or less restrictive... it can get very cold or very hot and shut the heater off. For example, adjusting the shower valve colder reduces the water flow through the heater, slowing down the flow and making the water so hot it shuts off the heater via the overheat (no automatic thermostat, only the manual dial). Or if we select the shower valve even colder, it reduces the flow (hot water) through the heater so much it will shut off the heater. I need something like a standard household tankless heater, but I can't rely on 110V for power... it needs to be low voltage (ie. D-cell batteries or even 12VDC would work). My heater is installed outside but under a roof so its always out of the weather and can be vented right out the top without powered ventilation. Has anyone found one that would be suitable? Thanks! |
