Installation of Tankless Water Heater

[donnamatrix]

We are contemplating the installation of a Rinnai tankless water heater to replace the electric storage water heater that was originally installed in our home. We have received estimates from several area companies for the purchase and install of the unit. Bay Street Discount in Ossipee has tendered an attactive estimate for the unit and has recommended a plumber to install the unit. Has anyone had any dealings with Bay Street Discount on this sort of installation? We would be very interested in hearing any comments on this company and on your experiences with these tankless water heaters.
