Testimonial

  • "When I purchased your product last fall, you asked if I could give you an update on how they performed. I'm very happy with them. I believe I saved approximately one half tank of oil, about $300 depending on the price. They were fairly easy to install and don't look too obvious. I found the house ( 2 storey, built in 1946, oil heat, cast iron rads) more comfortable overall. Glad I invested in them."
