I live in an apartment with limited space. I want to install a tankless electric water heater. My water comes from a tinaco so not much preasure so I will add a pump to increase the preasure to insure the water doesnt get too hot. All controlled by a wall switch to be used when showering. Has anyone seen either of these products here on the north coast. Years ago I remember seeing a heater at a store in Santiago but haven't seen one lately. Access to the required plumbing is easyily accesable in a closet behind bathroom. What do you think of my little plan. Winter is coming and that cold water on my back will likely give me a heart attack.
