DN25 12V/24V/48V 300W/600W 몰입 온수기 - 태양 관 히터
나는 이것을 골랐다 태양 관형 온수기 DIY 오프 그리드 물 난방 프로젝트 용. 가격은 미국에서 유사한 DC 히터에 대해 지불하는 것의 일부였습니다. 현지에서 $ 35 이상에 비해 약 12 달러입니다.
내 눈을 사로 잡은 것 : 그것은 단단한 구매자 리뷰를 가지고 있었고, 내구성이 있었으며, 유연한 전압 입력 (12V ~ 48V)을 제공했습니다. 스테인레스 스틸 SUS304 빌드와 소형 DN25 크기를 좋아했습니다. 작은 물 탱크 설정에 이상적입니다.
실제 사용 : 24V 배터리 뱅크에 연결되면이 일은 몇 분 안에 물을 가열하기 시작했습니다. 그것은 약 300W를 그리고 30 분 안에 5 갤런 컨테이너의 온도를 눈에 띄게 높였습니다. 빌드 품질 느낌 프리미엄-용접은 깨끗하고 실이 빡빡하며 표준 1 인치 NPT 개구부에 완벽하게 맞습니다.
장점 :
- 에너지 효율 및 태양 호환
- 저렴한 가격
- 고품질 스테인레스 스틸
- 누출이없고 설치하기 쉽습니다
단점 :
- 온도 조절기 없음 (수동으로 모니터링해야 함)
- 기본 포장, 지침 없음
미국 대안과 비교하여 : Grainger 또는 Amazon과 같은 미국 상점에서는 2 ~ 3 배 더 많은 비용이들 것입니다. 솔직히,이 aliexpress 버전은 더 나은 것이 아니라면 성능이 뛰어납니다.
최종 평결 : 기대치를 초과했습니다. 태양 광 발전으로 안정적으로 수행합니다. 큰 가치.

DN25 24V/36V/48V 스테인리스 스틸 전기 히터 1500W
나는 더 큰 탱크를위한 더 강력한 가열 요소를 원했고 이것과 함께 갔다. 1500W 전기 온수기 신뢰할 수있는 Aliexpress 판매자에서.
내가 그것을 선택한 이유 : 다목적 성 - 여러 전압 시스템에서 작동하며 300W에서 1500W까지 확장 할 수있는 기능은 게임 체인저였습니다. 계절 설정에 적합합니다.
Experience so far: I use it in a 10-gallon reservoir. Running it on 48V, the water heats up fast, almost too fast if left unattended. It definitely needs a controller or timer. The 1-inch DN25 thread matched my fittings exactly. It's also quieter than I expected – no humming or buzzing.
Pros:
- Heats water super fast
- Works across multiple DC voltages
- Solid SUS304 material
Cons:
- Requires an external thermostat
- Needs good ventilation if used indoors
Price comparison: Stateside, you'd pay over $60 for this level of power and material quality. This one cost me around $20.
Did it meet expectations? Yes – a solid addition for anyone building a solar water heater or DC heating system.
US $14.92 |

This DERNORD heating element with thermostat looked perfect for my off-grid hot water system. The built-in thermostat was a big selling point.
Why I bought it: I was tired of babysitting my heaters. Having an automatic shut-off seemed safer and more convenient, especially for overnight heating.
Using it daily: Installation was simple. The DN32 thread needed a minor adapter for my tank, but once set, it worked flawlessly. I tested it with both 48V and 96V setups – consistent performance on both. Thermostat kicks in accurately at the preset temp.
Pros:
- Built-in thermostat
- Excellent voltage range
- Reliable DERNORD quality
Cons:
- Thread size not universal
