Calculate estimated daily, monthly, and yearly electricity costs for your aquarium equipment including heaters, lights, and filters.
Enter the wattage and daily usage hours for each piece of equipment. The electricity rate should be your base cost per kWh.
Heater actual run time varies based on the difference between set temperature and room temperature. In winter, 8-12 hours is a common estimate.
Calculated costs are estimates. Actual bills may vary depending on tiered pricing structures in your local area.
计算器采用功率×使用时长×电价单价的方式计算。加热棒会间歇性启停,实际运行时间随室温不同约占每天30%~70%;灯具和水泵开启时通常全功率运行,对应数值相对准确。
可查看产品铭牌、说明书或厂商官网。加热棒功率通常印在棒体上;LED灯请使用系统输入功率而非LED输出功率;水泵会同时标注输入功率和流量。
加热棒只在水温低于设定值时才运行。冬天室内温度低,加热棒一天可能运行60%~80%;夏天可能只需运行10%~20%。冬季预算建议用高估值,年均成本则用低估值。
不建议整天开灯。鱼缸和水草缸每天6~10小时光照是业界标准做法,光照过长容易诱发藻类暴发并浪费电能。使用定时器是保持稳定光周期最简便高效的方法。
以200W加热棒(运行率30%)、30W LED灯(每天8小时)和20W外置过滤器(全天运行)为例,每天约消耗2.7 kWh。按每度电0.15美元计算,每月约需12美元。
