Do you have an electric boiler and use spot electricity prices? Or do you have a solar PV system, but are not yet using your self-generated electricity for intelligent boiler control?
We are looking for early users who would like to try Yellow Grid in real-life operation and help us further improve automatic water heating control.
Pilot installation from CZK 2,000 including VAT.
The device is yours to keep.


Who Are We Looking For?
A. You Have an Electric Boiler and Use Spot Electricity Prices
Yellow Grid automatically analyses electricity prices and schedules water heating during the most cost-effective periods of the day.
We are looking for households with an electric boiler that is not yet automatically controlled based on current electricity prices.
B. You Have an Electric Boiler and a Solar PV System
Yellow Grid uses your solar PV generation forecast and schedules water heating primarily for periods when your own electricity generation is expected.
We are looking for households with a solar PV system whose electric boiler is not yet automatically controlled based on solar generation.
What Do You Get?
-
automatic boiler control,
-
the opportunity to reduce water heating costs,
-
more efficient use of low spot electricity prices or your self-generated solar energy,
-
access to the Yellow Grid solution at a special pilot price,
-
the opportunity to contribute to the further development of the product.


How Does the Pilot Testing Work?
Sign up → We check whether your installation is suitable → We select the right device version → Yellow Grid instalation → You start testing
How Does Yellow Grid Work?
We connect Yellow Grid → The system learns → Every day it analyses electricity prices or the solar PV generation forecast → It creates an optimal heating schedule → It automatically controls your boiler
FAQ
Is Yellow Grid Compatible with My Electric Boiler?
Yellow Grid is compatible with virtually all common types of electric boilers. If you are unsure whether your boiler is suitable, contact us and we will be happy to advise you.
Do I Need to Have a Spot Electricity Tariff?
No. We are looking for two groups of users for the pilot testing programme – households using spot electricity prices and households with a solar PV system whose boiler is not yet automatically controlled according to solar PV generation.
How Does Yellow Grid Work with a Solar PV System?
Yellow Grid uses a forecast of your solar PV generation based on weather forecasts and expected solar irradiance. It then automatically schedules water heating primarily for periods when your own electricity generation is expected.
Do I Need an Electrician for the Installation?
If your boiler is connected using a standard mains plug, the Yellow Grid unit is simply installed between the electrical outlet and the boiler. If your boiler has a fixed electrical connection, the installation must be carried out by a qualified electrician.
What If There Is Not Enough Hot Water?
Yellow Grid monitors the water temperature and continuously learns your household's hot water consumption patterns. The aim is to reduce electricity costs or make better use of your own solar PV generation without compromising your normal hot water comfort.
How Does Yellow Grid Connect to the Internet?
Depending on the selected device version, Yellow Grid connects via Wi-Fi, Ethernet or LTE. The Internet connection is used to communicate with the Yellow Grid cloud platform and automatically receive water heating schedules.
How Much Does It Cost to Take Part in the Pilot Testing Programme?
As part of the pilot programme, we offer the devices at special introductory prices:
YG Heat 2KZ (LAN/Wi-Fi): CZK 2,000 including VAT
YG Heat 1HZ (LTE): CZK 3,000 including VAT
What Is Expected of Me as a Tester?
Simply use Yellow Grid as you normally would. You do not need to keep any records or regularly complete questionnaires. As this is a pilot programme, we ask for some understanding while the solution is being tested and will appreciate any feedback you may have about your experience.
Can I Keep the Device After the Pilot Testing Programme?
Yes. The Yellow Grid device remains yours after the pilot testing programme ends.
