How to Reduce Electrical Load in a Tiny House: 6 Step Guide

To reduce electrical load in a tiny house, move your biggest electric draws usually the water heater and range, over to propane. Add a soft start device to the AC compressor and switch every fixture to LED lighting. 

These changes typically cut peak demand from well over 30 amps to under the standard 3,600-watt tiny house service.

How to Reduce Electrical Load in a Tiny House: Step by Step

Reducing electrical load in a tiny house works best top-down: knock out the two biggest electric draws first, then clean up what's left.

1. Add up your peak concurrent load: List the running watts of everything that could realistically run together then compare the total to your service size, typically 3,600 watts on 30 amps.
2. Move the water heater to propane: It's usually the single biggest circuit in a tiny house, pulling 1,300 to 4,500 watts and propane removes that load from the panel completely.
3. Convert the range or cooktop next: Electric cooktops draw 1,800 to 3,000 watts per burner in use so switching to propane frees that circuit for lighting and smaller loads.
4. Add a soft start device to the AC compressor: Startup surge not running wattage is what usually trips the breaker on a tight circuit.
5. Switch every fixture to LED. LEDs use at least 75% less energy than incandescent bulbs (U.S. Department of Energy, 2026) and it's the cheapest cut on this list.
6. Re-run your revised list: Add up the new peak load and confirm it sits under your 30-amp ceiling before you trust it on the road.

The Mistake That Costs You a Tripped Breaker

Running your two highest mdraw appliances on the same circuit at once is the fastest way to blow past 30 amps even after every conversion above. Surge, not running watts. 

A 15,000 BTU RV-style AC unit can spike past 50 amps at startup, then settle to 12 to 14 running amps (TechnoRV, 2022). Stack that surge on a water heater or dryer already pulling power and the breaker trips.

💡 Pro Tip: Stagger your two heaviest loads by a few minutes instead of running them together and let a soft-start absorb whatever spike is left.

Bottom Line

Propane handles the two biggest drains. Surge control and LED lighting handle what's left. Do all six and reducing electrical load in a tiny house stops being a math problem you lose to a tripped breaker.
