Types of Systems We Service in Sunnyvale

Traditional Tank Water Heaters

Over time, sediment and hard minerals from Sunnyvale’s local groundwater settle at the bottom of traditional tanks, reducing efficiency.

  • Removes heavy sediment buildup
  • Restores heating efficiency
  • Prevents tank corrosion and leaks
  • Extends the lifespan of the unit

Tankless Water Heaters

Tankless systems are highly susceptible to scale buildup in their narrow heat exchangers, requiring specialized chemical descaling.

  • Eliminates internal mineral scale
  • Prevents error codes and lockouts
  • Maintains endless hot water flow
  • Protects the heat exchanger warranty
