Tankless water heaters deliver hot water on demand without the energy cost of keeping a tank warm. Heise's Plumbing installs and services gas and electric tankless systems throughout San Francisco and the Bay Area.
A loss of hot water, discolored water, or unusual noises from your water heater can disrupt your Water Heater Repair home. Heise's Plumbing diagnoses heating elements, thermostats, gas valves, and expansion tanks to deliver reliable repairs or energy-efficient replacements.
Water heater troubles often stem from mineral sediment buildup, failed heating elements, faulty thermostats, or malfunctioning gas control valves.
Our technicians test electrical components, gas pilot assemblies, thermal expansion tanks, and temperature-pressure relief valves to locate the exact malfunction.
When tank corrosion or age makes repair impractical, replacing your system with a high-efficiency tank or tankless water heater restores reliable hot water.
Tankless systems heat water on demand, saving energy and providing endless hot water while freeing up valuable utility space.
Proper installation requires upgrading gas flex lines, installing thermal expansion protection, securing earthquake straps, and verifying venting safety.
Heise's Plumbing ensures every installation complies with local municipal plumbing and gas safety codes.
