Low Energy Systems - Tankless Water Heaters
What they say:"Tankless Water Heaters by Low Energy Systems.
Low Energy Systems, founded in 1977, is the leader in the distribution of the amazing Paloma and Takagi tankless water heaters. If you don't yet have a tankless water heater you are probably paying $50 or more per month only to MAINTAIN heat in your tank type water heater. WHY? Because the tank loses its heat up the flue and then reheats, even while you sleep or are at work.
The tankless water heater never runs out of hot water. Some models can keep up with two showers at the same time indefinitely. What's more, you only pay for what you use."
