A smart immersion is the lowest-cost flexible device in your home - and one of the highest-impact. We run the cylinder when electricity is at its cheapest and cleanest, so you wake up to a tank of hot water without paying daytime rates.

Shift the immersion out of standard rate and into the night-rate window. Typical home saves €120–€220/yr - on a small device.
We learn your usage pattern - shower times, dishwasher cycles - and make sure the cylinder is full ahead of demand.
Smart immersion controllers cost €200-€400 fitted. Payback typically inside a year, faster than any other VPP device.
If you have a smart controller (Eddi, Climote, Hive immersion, Solic) we plug into it directly. If not, we can recommend one - typical fit is €200-€400 and pays back inside a year.
No. We model your draw pattern and keep a buffer above predicted demand. You'll hit a hot shower every morning.
Yes - one tap. We step out of the way for any manual boost and return to schedule afterwards.
Yes. Solar diversion (Eddi, Solic) takes priority - we only kick in to top up after solar has done what it can.
