Ipul really frustated because he purchased water heater for few times and still not get it right. He spoke with salesman, they are say the stuff was good and maybe just not fit with his needs. And they are recommended him the next level for upgrade and he should pay more for that.
Ipul doesn’t believe the salesman anymore. Now he search for tankless water heater reviews on the google. And found some recommendations that he used as his guide to kick that salesman ass.
Few days later he purchased new one, a single point type that perfectly fit with his needs in other store. And ask the local service provider to install it in proper way.
