    Love The Heater
    I was disappointed that my lovely heater was installed by someone who was unfamiliar with the product. The installer had to come back again with an assistant and re-do all the pipe work because it was leaking and the temperature control had to be adjusted for the bathroom. He was not aware of the difference of temperature required for the bathroom and other areas of the house. This must have cost the company money to fix the installation.
