Lower bills
Reduces hot water bills by up to 60%, when integrating with Octopus Agile smart tariff.
Solar X
Smarter solar with stronger SAP performance
Mixergy Solar X stores surplus solar energy as hot water, cutting energy bills and emissions, while reducing the amount of solar PV needed to met SAP compliance. Ideal for housing, new build, and commercial use.
Solar X is optimised for SAP compliance, achieving required scores with fewer solar panels and lower overall system costs.
The benefits of maximising Solar PV
Maximise use of solar energy by dynamically diverting excess PV into hot water, creating a solar hot water battery.
-
Cut hot water energy bills by up to 60% (when integrated with Octopus Agile smart tariff)
-
Improve SAP outcomes with a lower cost of comliance
-
Support grid flexibility with intelligent energy scheduling
- Heats only what’s needed for faster delivery and less waste, with direct electric or gas
Hot water battery
Automatically diverts excess solar energy to generate hot water
SAP compliance
Reduces the amount of solar PV required to meet SAP compliance.
Homeowners at a Cala Homes (East) development save up to 250kg of CO2
CALA Homes East used Solar X to cut carbon emissions and energy bills, achieving strong SAP performance while maintaining a premium homeowner experience.
I love the fact that our homeowners come to life when we explain how Mixergy works. It’s simple and effective. Contractors also like the product as they find it easy to install, just like a traditional cylinder. For Cammo Meadows, we needed a product that would work with both solar PV and gas boilers to help us make that transition to a gas-free domestic environment which is why we chose Mixergy.
