We are all aware by now that the standard storage tank water heater is out-dated technology that does not meet our needs for fuel efficiency and reduced carbon emissions. We know that 45% of the gas used in our homes is attributed to our Domestic Hot Water needs. Many people have researched tankless water heaters, also known as Flash water heaters or on-demand water heaters and found that they can increase efficiency dramatically and produce endless hot water with reduced carbon emissions. This same research may have led them to the conclusion that there are some draw backs to tankless technology- long delays in hot water delivery to fixture with increased water wastage and high cost of installation in some cases.
There is another solution to the Water Heater problem, High Efficiency Condensing Water Heaters.
