Heating/Cooling & EV Charging in One

The electrification of transport and heating is essential to cut CO2 emissions. 95% of new homes come with a heat pump and wiring (at least) for an EV charger installed. Whether it is retro-fitting an old home or building new homes EV Chargers and Heat Pumps will be everywhere. 

EVHACS system combines EV Charging, heating or cooling and delivers the best of both worlds; A smart EV Charger, load balancing, power management, and demand side response to alleviate pressure on the grid. It is cheaper than separate devices, easier to install, requires fewer materials and less labour

How we install EVHACS

Your heat pump is, ideally, installed to the side of the house.
Your heat pump arrives with EVHACS' EV Charger installed inside
We install a small communications box beside the consumer unit in your home.
We connect our ELLIoT comms unit to the EV Charger with a cable. Your charger can now be controlled from our app.
The combined heat pump and EV charger are connected to your home's power from the consumer unit.
Your system is ready to start charging!

What is Load Balancing?

Most homes in Ireland have anything from 52 to 70 Amps available to them. That's a maximum of 12 to 16kW at any time. Most modern houses use an "ambient" 0.5kWh (approximately) of power throughout the day, that's your fridge, phone chargers, radio, TV etc.
Add onto that 0.5kWh of consistent use, another consumer of power; heat pumps. Around 3 - 7kWh.
Now turn on your car charger, you can see that there's very little power left for your home to use.
It's 6pm, everyone is home, you turn on the oven. If anything else is turned on your mains circuit breaker will trip and you're left in the dark.
Some smart chargers, including ours, will turn down the power going to your car during peak demand so that you can, literally, keep the lights on.
EVHACS is the ONLY system that gives you the power to choose between prioritizing your heating or EV charging during peak times.

What is Solar power matching?

Solar panels generate DC electricity. It's then sent to an invertor which changes it to AC.
The power is sent to the consumer unit/switch board in your home.
This power is first used to keep your home running.
If you have a battery installed, leftover over power is sent to charge it.
Some people splash out on a divertor which will then direct leftover power to the hot water tank.
At this stage leftover power is then sold back to the grid.
EVHACS senses that the power is going back to the grid and reroutes it to the EV Charger.
When the car is charged EVHACS sends it to the heat pump, which heats the hot water.
All without having to buy an expensive diverter.
Once your home is powered, the battery is full, the car is charged and the hot water tank is full, then, and only then...
