On-Demand Hot Water System Benefits and Costs

Until independent verification of the water and energy savings from on demand hot water systems becomes available it is not possible to accurately calculate the benefits and costs of these devices.

On demand hot water systems start at around $200 and go up from there. There cost depends on the type of system purchased.

If the energy savings are in the neighborhood of $200 per year (as suggested by some manufacturers) then these devices would indeed be cost effective and the payback period would be easily within the life expectancy of the product.
