Cross-appliance guides: repair vs. replace decisions, energy efficiency, extended warranty analysis, and general maintenance strategies.
Not every appliance question fits neatly into a single category. Should you repair a 9-year-old refrigerator or put that money toward a new one? Is an extended warranty worth the price? How do you find a reliable repair technician who won't upsell unnecessary parts? These cross-cutting questions affect every appliance in your home, and our general guides tackle them with data from thousands of real repair jobs.
The repair-vs-replace decision is the most common question we get, and the answer depends on three factors: the appliance's age relative to its expected lifespan, the cost of the specific repair relative to the replacement cost, and whether the failure is a one-time event or a symptom of cascading wear. We publish a decision matrix for every major appliance type, updated annually with current parts and retail prices.
Energy efficiency guides in this section go beyond the yellow EnergyGuide label. We break down the real-world operating cost differences between models, explain California-specific utility rebate programs (SMUD, PG&E, SCE), and calculate the payback period for upgrading from a working but inefficient appliance. These numbers change yearly, and our guides reflect current rates.

A fan-forced garage heater comes in two very different circuits. The mounted 240-volt version is hardwired, drawing 20 to 30 amps for 5,000 to 7,000 watts.
A hybrid heat-pump water heater runs on 240 volts, wired directly, and draws anywhere from 15 to 30 amps for 500 to 4,500 watts behind a 30-amp breaker — the.
A hot-water recirculating pump is one of the smallest loads in the house, running on 120 volts at just 1 to 2 amps through a 5-15R outlet on a 15-amp branch.
A pellet stove is really an electric appliance that burns fuel, running on 120 volts through a 5-15R outlet on a 15-amp branch.

A 240-volt in-ground pool pump draws 10 to 12 A for 2,400 to 2,880 W on a 20 A ground-fault-protected circuit, an above-ground 120-volt pump 8 to 12 A — plus what the wet location demands beyond the breaker.
A single-hose portable AC draws 10 to 12 A at 120 V and a dual-hose 11 to 13 A — plus a table on what the room circuit you are plugging into is already carrying, and where it gives out.
Electric radiant floor heating is a resistive cable or mat under the tile, wired directly to a ground-fault floor thermostat rather than any outlet.
A home sauna heater is a heavy 240-volt load wired directly to a controller outside the hot room, with no plug.
A sewage ejector pump lifts waste from a below-floor basin up to the main drain. A 120-volt ejector draws 7 to 12 amps for 840 to 1,440 watts on a 15 to.

A sump pump runs on 120 volts through a 5-15R outlet. A submersible unit draws 6 to 10 amps for 700 to 1,200 watts on a 15 to 20-amp branch, while a pedestal.
A gas tankless heater does its warming with a burner but still needs a trickle of 120-volt power through a 5-15R outlet on a 15-amp branch.
A fan-forced wall heater is a recessed unit wired straight to its own thermostat, never plugged in.
A welder runs on 240 volts and draws its rated current only in short arcs. A stick welder pulls 40 to 48 amps for 9,600 to 11,520 watts on a 50-amp circuit.
A well pump is wired through a pressure switch, not a plug. A 240-volt submersible pump hangs down the casing and draws 8 to 13 amps for 1,920 to 3,120 watts.
A whirlpool tub sits full of water beside its motor, so its circuit is ground-fault protected and dedicated.

Built-in coffee system electrical specs: it runs on 120 volts, draws 10 to 13 amps, and wants a 15-to-20-amp branch, ideally a dedicated circuit for the heating boiler.
Central AC amps, watts, breaker size and wiring: a 2 to 3-ton condenser needs a 30 to 40 A / 240 V circuit, a 4 to 5-ton unit 45 to 60 A.
