Tankless Water Heaters vs. Conventional


Did you know that 25% of each energy dollar that you spend goes to heat your home’s water?  And 20-40% of energy consumed by a traditional tank heater is wasted as heat is slowly lost due to radiant heat loss from the storage tank. You can reduce water heating costs by as much as 50% by having a tankless water heater installed in your home. They provide hot water when needed without a storage tank which reduces standby heat loss and in turn saves money. Since there is no hot water storage, thermal heat loss is almost completely eliminated. Tankless heaters are manufactured with an electric, natural gas, or propane heating device that is activated by the flow of water. Once activated, the water heater provides a constant supply of hot water.

Tankless heaters are perfect for new home construction, but they can also be used for remodeling, renovations, & additions. They provide distinct advantages over traditional types.  For example by adding a small unit in the new addition, you save plumbing costs by avoiding the need for new plumbing lines to be run from the existing whole house unit or the need for replacing the existing whole house unit in favor of a larger unit to accommodate the additional needs.

Other advantages are the ability to set the ongoing water temperature to a much more reasonable and safer temperature, closer to the actual temperature you will use the water at, thereby reducing risk of scalding. They also generally handle hard water minerals and sediments much better than conventional tanks. This makes them far less likely to leak or rupture, and able to maintain efficiency throughout their whole life cycle. Accordingly, many have much longer warranties.

Conventional water heaters typically last from 6 to 12 years in most residential applications. They are bulky, take up a huge amount of landfill space, and are costly to recycle. Tankless heaters are much smaller saving valuable floor space and can last more than 20 years.
