I dont have much space and i have an on demand water heater that uses my oil boiler to heat the water. I was looking at getting a water heater ( tank ) but realized i didnt have the space. I have natural gas that comes into my house for the stoves i have. I live in NYC.
My goal is to save money by having my hotwater come from a tankless system ( wall mount so lack of space is no issue).
Its costing me between 300 a month to get oil in the house and its the summer and for heating water its costing me alot.
So gentlemen shouldnt putting in a tankless unit save me money ?
