Product Description

The PV‑ESS Coupled Heat Pump is purpose‑built for homes equipped with photovoltaic panels and battery energy storage systems. Through native communication with the PV inverter and battery management system, the unit automatically synchronizes its operation with solar generation patterns – running at full capacity during peak PV hours to convert surplus electricity into thermal energy stored in the buffer tank, and reducing or pausing operation when solar generation drops. This intelligent coordination maximizes self‑consumption of renewable energy, minimizes grid imports, and significantly lowers electricity costs. The result is a truly integrated solar‑storage‑heat pump ecosystem that delivers year‑round comfort with minimal environmental footprint.

Products Advantages

Substantive yet chic, our R290 heat pump exudes sophistication without compromising on efficiency and reliability. Meticulously engineered, it combines intelligent control with sustainable performance for modern living.

Natural Refrigerant R290

GWP of just 3, fully compliant with EU F‑Gas phase‑down — an environmentally future‑proof solution.

HEMS‑Optimized Smart Control

Seamless integration with home energy systems, automatically adjusts to PV production and tariff signals, saving up to 30% on energy bills.

A+++ Seasonal Efficiency

SCOP up to 5.3, delivering the highest energy class for 35°C heating — dramatically lower operating costs.

Extreme Climate Reliability

Stable heating down to -25°C and water outlet up to 75°C — built for harsh winters and high‑demand applications.

Cost Advantages

A gas boiler costs €180/year, a conventional heat pump €220/year with TOU tariffs, while the TONGYI HEMS-optimized heat pump cuts costs to just €110/year—saving 39% vs gas and 50% vs conventional. The key insight: smart energy management, not the heat pump itself, drives real savings.

FAQ

Tell us about your project requirements and we will figure out a solution that will meet your budget and design expectations.

Is an R290 monoblock heat pump safe?

Yes. Although R290 is flammable (A3), modern units are designed with strict safety standards and controlled refrigerant charge.

Do I need an F-gas certified installer?

No. Monoblock systems do not require refrigerant handling on-site.

Is R290 better than R32?

R290 has significantly lower environmental impact (GWP ~3 vs ~675 for R32) and is considered future-proof under EU regulations.

Can it work with solar panels?

Yes. Tongyi systems are designed for PV integration and smart energy management.
