Heat pump · Virtual Power Plant

Same warm house.

Cheaper hours.

Heat pumps don't care exactly when you make the heat - they care that the room is warm at the right time. We'll pre-heat when the wind blows and electricity is cheapest, then let your home coast through the expensive 17-19 peak.

Air-source heat pump
Benefits

What you get

20-40% off your heating bill

Shift heat-pump runtime out of peak hours and into the cheapest windows. Typical SEAI Class A/B home saves €280–€520/yr.

Ride the wind

Irish overnight wind is the cheapest, cleanest electricity in the system. We schedule big heating cycles to land there.

Comfort stays put

Set your target temperature. We'll learn your home's thermal mass and sequence the runtime so it never drops below comfort.

Stats

By the numbers

  • Typical bill saving €280–€520/yr
  • Peak-hour run time −70% shifted out of 17-19
  • Comfort drift <0.5°C vs always-on baseline
  • Hardware needed None — API-controlled
How it works

Three steps

  1. Connect your heat pump. Daikin, Mitsubishi, Samsung, Vaillant, Grant Aerona³ and more. Integrates over the manufacturer's existing thermostat API.
  2. We learn your house. How fast it heats up, how slowly it cools. We model your home's thermal response and plan runtime around it.
  3. It runs in the cheap hours. Pre-heat on cheap wind, coast through the peak, top up overnight. You feel the same; the bill doesn't.
Common questions

Frequently asked

Will my house ever feel cold?

No. We always hit your target setpoint - we're just smarter about when the compressor runs to get there.

Which heat pumps do you support?

Most major brands with a public API: Daikin, Mitsubishi, Samsung, Vaillant, Grant, NIBE, Bosch. We're adding more weekly.

Does this work with underfloor heating?

Yes - underfloor's high thermal mass actually makes the savings bigger because we can pre-heat further ahead.

Will this affect my heat-pump warranty?

No. We use the manufacturer's intended control API, within their published operating envelope. No firmware changes.
