Technical Specifications
Product Description
Instant 70°C Hot Water – No Booster Needed
Unlike standard heat pumps that require electric boosters to reach 70°C, the TONGYI direct-heating system achieves this temperature in a single pass, eliminating additional energy consumption and equipment costs.
Eliminates Large Storage Tanks
Direct-heating mode heats water on demand, significantly reducing or eliminating the need for bulky storage tanks. This saves valuable floor space in mechanical rooms and reduces standby heat loss.
50–70% Energy Savings vs. Electric/Gas
Compared to traditional resistance heaters or fossil fuel boilers, this heat pump delivers dramatic reductions in operating costs and carbon emissions.
product advantages
01.Direct Heating, Instant High-Temp Hot Water
