Heat pump
CTC + Therilly
Therilly’s AI lets your CTC heat pump run when electricity is cheapest and preheats ahead of price peaks.
🔧CTC support is in development. Join the waitlist and we’ll reach out at launch.
CTC’s modern range communicates via CTC EnergyFlow and can also be reached through Home Assistant. When support launches, Therilly takes over time-based optimisation of your ground-source or air-to-water pump and shifts heating and hot water to the cheapest spot-price hours. Backed by weather forecasts, the AI preheats the house ahead of price peaks to save 15-30 percent.

Frequently asked questions
- How do I connect CTC to Therilly?
- Register your interest on the waitlist and we’ll reach out when the CTC integration is ready. At launch, link CTC EnergyFlow or Home Assistant to your Therilly account. Therilly reads in your EcoZenith or EcoPart model and starts spot-price optimisation right away.
- Do I need to install any hardware?
- Usually not. If you already have a power meter like Tibber Pulse, Shelly EM or HomeWizard P1, signing in to Therilly is enough. If you don’t have a meter, we recommend HomeWizard P1 which requires no electrician.
- Can I control the pump myself any time?
- Yes. You can pause Therilly at any time and take back full manual control via the pump’s normal app. Therilly does not take over — it sits on top.
- How is the heat pump connected?
- Depending on model, either directly via the manufacturer cloud (Qvantum, Mitsubishi MELCloud) or via Home Assistant or Homey Pro. The connection takes 2–5 minutes and only requires that you sign in with your existing account.
