Panasonic DH-6SM1PW Multi Point Water Heater

The product is fine and works well. However, the company handling the installation was not. They said it was free installation but if materials will be needed and used, the customer may supply them or repay the installer. The materials were way overpriced and the installer did not even inform us how much the materials will cost before using them nor ask us if we would like to supply them instead. We paid around 1,900 per water heater installed just for the materials.
