Smart PV Power Usage

Every building is unique—LAMBDA is adaptable

All LAMBDA heat pumps are fully modulating. This means they always generate exactly the amount of heating capacity needed to heat the building at any given moment. This results in lower energy costs, greater operational reliability, and continuous heat distribution throughout the rooms. Our heat pumps learn the characteristics of your building and automatically adapt to your needs. 

An intelligent control network takes into account and processes a wide range of factors. Ultimately, the heating demand is met in the most cost-effective, quietest, and most reliable way possible. And the best part is: our heat pumps learn over time! The next time they start up, they’ll reach the optimal operating point even sooner.

Connected Heat—the remote maintenance portal from LAMBDA Heat Pumps

With our highly secure, end-to-end encrypted remote access, you’re always in control, no matter where you are.
The Connected Heat remote maintenance portal from LAMBDA Heat Pumps is a multifunctional platform for end customers, specialist contractors, and service partners. Connected Heat provides secure remote access to the respective heat pump control system. 

Given the growing demands for energy efficiency and operational reliability, remote maintenance of heat pumps is becoming increasingly important. With the Connected Heat remote maintenance portal from LAMBDA Heat Pumps, systems can be conveniently monitored, controlled, and optimized remotely. Installers, service technicians, and end customers have access at any time to important heat pump information such as system status, type, serial number, or software versions, and can adjust settings or analyze malfunctions. Features such as remote access to heat pumps, centralized management of customer data, automatic fault notifications, and the storage of documents and maintenance logs significantly simplify service work. Continuous monitoring of the heat pump allows potential problems to be detected early and often resolved directly from a distance—saving time, reducing maintenance costs, and increasing the system’s operational reliability.

LAMBDA Heating Schedule® – Heat efficiently and lower your electricity costs

The LAMBDA Heat Schedule® combines intelligent control, weather data, and flexible electricity prices, while also taking into account the next day’s energy yield forecast for your home’s PV system, to make your heat pump operate more efficiently and reduce heating costs. An individual “heat schedule” is created for each subsequent day, which optimally distributes heat generation throughout the day.
By taking hourly variable electricity prices into account, the heat pump recognizes when electricity is particularly cheap or expensive. At the same time, hourly weather data is incorporated, allowing the heat pump to operate even more efficiently at higher outdoor temperatures. In this way, the Heat Schedule® automatically utilizes the most cost-effective times for heat generation and ensures energy-efficient operation.

All up-to-date data on electricity prices and weather is retrieved online via our remote maintenance portal, “Connected Heat.” In addition, provider-specific costs such as grid fees or taxes can be entered, ensuring that each heat pump is optimized for your electricity provider’s individual rate plan.
With the LAMBDA Heat Schedule®, your heat pump operates in a particularly cost- and energy-efficient manner, saving electricity while also reducing the load on the power grid.
