Pacific Tankless has been serving most of San Diego County for over 13 years. To all our customer and partners- thank you! Tankless water heaters provide hot water only as it is needed. There is no stand by heat losses associated with tank water heaters. Tankless water heaters heat water directly, without a storage tank. When a hot water tap is turned on any where in the house, cold water is heated directly as it passes through either gas or electric heat exchanger. As a result, a tankless water heater can deliver constant, endless supply of hot water using less energy. Most tankless water heaters last up to 20 or more years. Almost all tankless water heater models manufactured by Rinnai, Navien, Takagi/A.O. Smith, Rheem and Noritz are offered with 12 or 15 years heat exchanger warranty for residential use, and certain Noritz models are being covered for 25 years. Pacific Tankless is a leader in tankless water heater installations and conversions from tank to a tankless system. Pacific Tankless offers free onsite consultations and estimates, fast and professional installations, and extremely competitive pricing and financing.
