Living here is much easier than before, the maintenance of the house is just simpler, we don´t have to worry about heaters, filling the tanks with fuel or radiators.

Ralph and Beth Peters

In this past year, with HST we have paid a total of $1872.63 for all of our electrical needs including our heating, hot water, and domestic electrical needs. For our 1950 sq ft home and our family of 6, I think we have done fairly well.
