The Pain: Kitchen Too Far from the Heater
Gas heaters usually sit on a balcony or near the bathroom. With 8m+ of pipe to the kitchen sink, every rinse starts with a half-pipe of cold water.
Three Plans
| Plan | Cost | Experience | Best for |
|---|---|---|---|
| Independent under-sink heater | 300-600 CNY | Instant, independent | Most families |
| Zero-cold-water gas heater | 2000+ CNY | Whole-house instant | Full renovation planning |
| Add-on circulation pump | 500-1500 CNY | Waits for circulation | No-rewire retrofits |
Why Most Choose the Under-Sink Unit
Low upfront cost, no gas-side changes, instant heat. Zero-cold-water systems are comfortable but costly and burn extra gas just for dishwashing.
Recommended Combo
Leave showers to the gas heater and kitchen tasks to the under-sink unit — the best cost-experience balance. A 5L/6L model is usually enough.
