Water heater replacement in San Diego.

Tell us what is installed now and whether you want a similar unit, tankless, or heat pump so we can review the equipment, site, and schedule.

We replace water heaters. We do not offer repairs.

Call to confirm service

Choose between replacement and conversion

A compatible replacement needs different information than a conversion.

Replace with a compatible tank

Start with capacity, fuel, dimensions, connections, venting, drainage, seismic restraint, and access. For a single-family home or duplex, San Diego lists basic replacement as Simple MEP work: a permit is required, but plans are not required for that basic scope.

  • Same equipment type and location
  • Existing utilities remain the comparison point
  • Confirm property type and jurisdiction

Convert the system

San Diego separately says tank-to-tankless conversion requires plans and plan review. Equipment selection follows a site check for gas or electrical capacity, venting, condensate, mounting, clearances, and service access.

  • New system type or fuel
  • Possible utility and vent changes
  • Conversion-specific review before timing

Before comparing permits

First decide whether the job changes how the home heats water.

A compatible tank starts with the connections already in place. Tankless, heat pump, relocation, or a fuel change can add electrical, gas, vent, drain, space, and plan questions. That distinction determines which city guidance applies.

San Diego permit comparison

Do not treat a conversion as a simple changeout.

Published city guidance explains why a compatible replacement and a conversion need different preparation.

Make the call concrete

Photos let the conversation start with the actual installation.

A clear view of the heater, label, connections, and access route helps separate a straightforward replacement from work that changes utilities or location. It reduces guesswork before an on-site check.

Photos to send before calling

Send these views of the heater and installation area.

  1. Full installationShow the heater and surrounding space.
  2. Rating labelKeep model and capacity readable.
  3. Top connectionsInclude water, vent, or wiring.
  4. Lower connectionsShow gas, electrical, pan, and drain.
  5. Access routeInclude doors, stairs, and tight turns.
  6. Desired outcomeState replacement or conversion.

What to share for an estimate

Tell us what is installed now and what you want to change.

For a compatible tank, the useful comparison starts with the existing capacity, fuel, footprint, water connections, vent or circuit, drain arrangement, and the route used to remove the unit. A conversion adds a different set of unknowns: available gas or electrical capacity, manufacturer clearances, mounting surface, condensate routing, exhaust path, and service access. Photos support the first review but do not establish that the installation is code-compliant. Property type and jurisdiction also matter because the cited Simple MEP description is limited to the city guidance and the stated residential context. These inputs explain scope without relying on an unsupported flat price or a citywide timing promise.

Existing system
Fuel, capacity, label, location, connections, venting, drainage, seismic restraint, and access.
Requested change
Keep the type, convert to tankless or heat pump, change fuel, or move the installation.
Property conditions
Exact address, building type, clearances, finished surfaces, removal route, and permit context.

Conversion questions

Questions to answer before choosing equipment.

Does a basic replacement require plans?

City guidance lists basic water-heater replacement as Simple MEP work for a single-family home or duplex: a permit is required, but plans are not required for that basic scope. Property type and jurisdiction still need confirmation.

What changes for tank-to-tankless conversion?

San Diego guidance says that conversion requires plans and plan review. The site also needs review for fuel or electrical capacity, venting, condensate, clearances, and mounting.

What should I send before calling?

Send the exact address, property type, heater label, wide and close photos, current fuel, access route, and whether you want the same type or a conversion.

Can it be completed today?

Call before noon to ask. Completion by evening may be possible, but the schedule, equipment, site conditions, and permit requirements must be confirmed by phone.

Continue with the replacement that fits

Tell us whether you plan to keep or change the system type. Evening completion requires phone confirmation of schedule, equipment, site conditions, and permit needs.
