Good evening people, consult: in the laundry room of my house I have an old water heater installed with a pilot. It has left side exit. Now I want to replace it with a new one (automatic). X the prices that I saw, those of lateral exit are much more expensive than those of later exit x ex. The question is: Can I buy one with a back outlet and what does the gas station suit me? The issue is that in the back where the heater should be placed I have a wall. On the left side x ex q is how the current one is installed there is a window and everything is already arranged for that side to exit. What dou you recommend? Best regards.
