Frequently Asked Questions

What are the main advantages of an Air Source Heat Pump?

It offers high energy efficiency (saving up to 2/3 cost compared to electric heating), high environmental safety (no open flames/emissions), and superior comfort through stable water-system heating and cooling.

Can it work in extremely cold weather?

Yes, our units utilize EVI (Enhanced Vapor Injection) technology, allowing them to operate effectively in ambient temperatures as low as -35°C.

How long is the service life of these units?

The design life of core components is more than 15 years. Regular maintenance can further extend the equipment's operational lifespan.

What is the standard delivery time?

Sample orders typically take 35-45 days after deposit, while bulk orders are delivered within 25-40 days.

What kind of warranty do you provide?

We provide a two-year warranty after the shipping date. During this period, we supply free spare parts for any manufacturing-related issues.

Is smart control supported?

Yes, the units support Modbus protocol for BMS integration and offer an optional WiFi function for smartphone control anywhere, anytime.
