Solar Power Hot Water System

1.Break the "only roof installation" restriction, solve the installation problem of high-rise residential buildings and sloping roof buildings;

2.The indoor heat storage environment makes the heat loss coefficient <5W/℃, which reduces the heat loss by 60% compared with outdoor installation;

3.Modular design supports synchronous construction with the building to meet the requirements of green building star certification.

Product Details

In the hot water solution of multi-storey houses and villas, the solar split water heater solves the traditional installation pain point with "separate design":

When the collector receives sufficient sunlight on the roof, the heat transfer medium continuously delivers thermal energy to the indoor water tank. —— This 'external heat collection, internal heat storage' design not only avoids the safety risks associated with concentrated roof load-bearing but also reduces heat loss through an insulated indoor environment. Especially in winter, the split structure, combined with a freeze-resistant medium circulation system, improves energy efficiency by 30% compared to traditional all-in-one units, making it an ideal choice for high-end residences that prioritize both architectural aesthetics and functional compatibility.

System advantages:

Break the "only roof installation" restriction, solve the installation problem of high-rise residential buildings and sloping roof buildings;
The indoor heat storage environment makes the heat loss coefficient <5W/℃, which reduces the heat loss by 60% compared with outdoor installation;
Modular design supports synchronous construction with the building to meet the requirements of green building star certification.
