How does a water heater work with solar panels?

When your solar panels generate more than the house needs at that moment, our smart EMS sends the surplus to the heater to warm your water. Thanks to the smart heating element we supply with it, that surplus goes to good use instead of going to waste.

Which size heater should I choose?

For a household of one or two people, our 150 litre heater is a good choice. For three or four people we recommend at least 200 litres. Larger family, plenty of hot water, and you would rather be on the safe side? Then 300 litres is an excellent choice.

How much gas do I save with a smart water heater?

A smart electric water heater cuts the gas you use for hot water by up to 80%.

What is a smart water heater?

A smart electric water heater heats water with electricity and stores it for use around the house. Whether you are taking a shower or doing the dishes, it runs entirely on electricity, unlike a gas boiler.

Easy to use: a smart app on your phone makes setting the heater and watching your use simple.
Built to last: the heater is designed with sustainability in mind and lasts for years, which shrinks your footprint.
Sizes: available in 150, 200 and 300 litres, so there is always one that fits your household.

How our smart water heater optimises your energy use

Our electric water heaters come with the linear AC ELWA 2 heating element from My-PV. That smart element works seamlessly with our energy management system (EMS) to put surplus solar energy to work heating water. So you use as much of your own energy as possible and avoid unpredictable feed-in charges and rising energy costs.

Automatic optimisation: Max adjusts the energy settings by itself, based on your use and on the solar energy available.
