Frequently Asked Questions

Common questions about water heater replacement in Walnut Creek. Don’t see yours? Call (408) 444-2696.

How do I choose between a tank and tankless water heater?

Tankless units provide endless hot water and use less energy but cost more upfront. Traditional tanks are lower cost to install and simpler to maintain. We’ll walk you through the trade-offs for your Walnut Creek home.

How long does water heater installation take?

Most installations are completed in 3–5 hours. Tankless installations requiring new gas lines or electrical work may take longer.

What size water heater do I need?

Household size is the primary factor: 40 gallons for 1–3 people, 50 gallons for 3–5, 75+ gallons for larger families. Tankless sizing depends on simultaneous hot water demand.

Do you haul away the old water heater?

Yes — old unit removal and disposal is included with every water heater replacement we perform.

Are permits required for water heater replacement in Walnut Creek?

Yes, California requires permits for water heater installations. We handle the application and schedule the inspection on your behalf.
