As a former plumbing contractor,Cheryl Ashida’s letter (April 12) regarding the installation of tankless water heaters to conserve water needs clarification.
Removing a storage-type water heater and replacing it with a tankless water heater in the same location will do nothing to conserve water because the hot water source is still the same distance from the fixture calling for hot water.
To truly conserve water, one would need to install a hot water recirculating pump in their potable water system. Doing so would assure hot water would always be on hand when the tap is opened.
Hot water recirculating systems start at around $500, but the payoff in instantaneous hot water and water conservation is something everyone should consider during this drought.
