A replacement that fits your home

Start with your hot-water needs, not just a new unit

Water heater replacement in Danville or San Ramon begins with understanding the equipment you have and how your household uses hot water.

We evaluate the current heater, signs of leakage or corrosion, connections, installation space and available fuel or electrical supply. A repair may be the right choice if the problem is isolated to a component.

For replacement, consider household size, simultaneous showers and appliance use, available space and your plans for the home. Traditional tanks store heated water; tankless units heat it on demand. Neither is automatically the best choice for every house.

Professional installation matters because water, fuel, electricity and venting need to work safely together. Equipment sizing, local installation requirements and inspection considerations all belong in the plan.

What to discuss before choosing

  • Your current heater's type, capacity and condition
  • When your household runs out of hot water
  • Tank replacement versus a tankless conversion
  • Fuel, electrical, venting and space requirements
  • Equipment, installation and permit costs

Traditional Tank Water Heaters

Stored hot water, ready when you need it.

A familiar option for everyday household use. Match tank capacity and recovery rate to your family's peak demand.

Considerations: Consider available space, fuel type and how quickly the tank replenishes hot water after heavy use.

A fit for: Homeowners comparing a like-for-like replacement with their current tank.

Tankless Water Heaters

Hot water heated on demand.

A compact system that heats water as it flows. Proper sizing accounts for the fixtures you expect to use at the same time.

Considerations: Review gas supply or electrical capacity, venting and maintenance before choosing a conversion.

A fit for: Homeowners considering on-demand hot water and a smaller equipment footprint.

High-Efficiency Water Heating Systems

Another way to meet your home's hot-water needs.

Heat pump water heaters use electricity to move heat from surrounding air into the water. Suitability depends on the installation location.

Considerations: Check airflow, space, noise, condensate drainage and electrical requirements. Actual energy use varies by household.

A fit for: Homeowners exploring electric water heating and an appropriate location for heat pump equipment.

Know the warning signs

Repair or replace? An evaluation can help.

Not every problem requires a new water heater. These signs are reasons to have the equipment checked, not a diagnosis on their own.

  • Water leaking around the heater
  • Inconsistent water temperature
  • Not enough hot water
  • Frequent or recurring repairs
  • Corrosion or visible deterioration
  • Aging equipment with declining performance

A leaking connection may be repairable; deterioration of the tank itself is a different issue. Tell us what you are seeing so we can discuss the appropriate next step.

Water heater questions, answered

Frequently asked questions

How much does water heater replacement cost in Danville, California?

Your estimate depends on the equipment, its capacity, installation requirements, permits and existing plumbing configuration. Gas, venting or electrical changes can affect the scope. Contact Polis Plumbing for recommendations and an estimate specific to your home.

How long does it take to replace a water heater?

Timing depends on access, the type of equipment, required plumbing or electrical changes, and permit and inspection scheduling. A straightforward replacement has a different scope than converting to tankless or heat pump equipment. We can discuss the expected schedule after evaluating your project.

Should I replace my water heater with a tankless system?

Tankless can suit homeowners who want on-demand hot water and a compact unit. The right choice depends on simultaneous hot-water use, available fuel, venting, installation space and maintenance needs. A tankless conversion may require changes to gas supply or venting; compare the complete installation scope, not just the unit.

How do I know if my water heater needs replacement?

Recurring repairs, corrosion, deteriorating equipment and a leaking tank can point toward replacement. Inconsistent or insufficient hot water can also come from repairable components or sizing issues. A professional evaluation helps distinguish a repair from a replacement.

Can a leaking water heater be repaired?

Sometimes. A leak at a connection or valve may be repairable, while a leak from the tank itself generally calls for replacement. Have the source checked promptly. If water is near electrical equipment, avoid the area and seek professional help.

What size water heater do I need for my home?

Sizing depends on household size, peak hot-water use, fixtures and whether showers or appliances run together. Tank selection considers stored capacity and recovery; tankless selection considers flow and the required temperature rise. Your current unit's size alone may not be the best guide.

Does Polis Plumbing install tankless water heaters?

Yes. Polis Plumbing offers traditional tank, tankless and heat pump water heater services. We can review your home's hot-water needs and the changes required for a tankless installation.

What areas does Polis Plumbing serve?

Polis Plumbing serves Danville, San Ramon, Alamo, Dublin, Pleasanton, Walnut Creek and nearby East Bay communities. Call to discuss your project and confirm service at your address.

Do I need a permit to replace a water heater in California?

Check with the building department responsible for your address before work begins to confirm the permit and inspection requirements for your project. Danville publishes water-heater installation requirements and provides an online permit center. Addresses outside town limits may fall under county jurisdiction; requirements vary by city and county.
