COP Angel - There’s no better way to Control Heat Pumps

What if we told you... there’s a way to control a heat pump that it’s impossible to surpass?

Imagine a system that doesn’t rely on guesswork, external weather data, or user intervention - but instead uses real, measured system data to continuously optimise itself.

• Automatically balances every radiator in the home
  Why it matters: Properly balancing at low flow temperatures is notoriously hard because the temperature drop across each radiator (ΔT) is small; tiny valve tweaks can starve one room while over-feeding another. Manual lockshield balancing also drifts as rooms heat, doors open, and occupancy changes. By using return-pipe sensors inside the valves, COP Angel can see which emitters are under- or over-performing and continuously adjust each valve to equalise return temps, achieving true dynamic balance even at 25-35 °C flows. That improves comfort and cuts pumping and compressor work because heat is distributed precisely where it’s needed.

• Sizes the heat pump and radiators with precision
  Why it matters: Oversized heat pumps short-cycle and run at higher instantaneous power/temperature, hammering COP and comfort; undersized systems risk cold rooms in peaks. Because COP Angel drives long, steady, low-power operation and reveals the real-world emitter capacity at low temperatures, it de-risks right-sizing. Early indications show the required kW can be lower than conventional specs, and existing radiators can perform better than expected when controlled this way - reducing capex and retrofit disruption.

• Continuously self-commissions
  Why it matters: Traditional commissioning (balancing, curve tuning, thermostat settings) assumes fixed conditions. Homes aren’t fixed. COP Angel eliminates room thermostats and uses sensor feedback to keep adjusting valves and flow temperature automatically, so the system re-commissions itself as the house and seasons change. That means fewer call-backs, less installer skill dependency, and consistent performance over time.

• Reduces flow temperature automatically to match real-world heat demand
  Why it matters: Heat pump efficiency rises sharply as flow temperature falls. Example lab data at 7 °C ambient shows COP ~4.59 at 35 °C vs ~3.11 at 50 °C - a >32% gain for the same heat output just by lowering flow temperature. COP Angel’s control logic constantly seeks the minimum flow temperature that still maintains setpoints, unlocking those gains in daily operation (not just in tests).

• Achieves the lowest possible flow temperature without losing comfort
  Why it matters: Running too cold causes rooms to drift below setpoint. COP Angel avoids that by controlling room temperature via water temperature (not on/off thermostats) and by balancing emitters so every room gets its share. The result is steady indoor conditions with minimal ΔT across emitters, slower convective air movement, and higher delivered-per-kWh comfort.

That’s COP Angel - a patented smart control technology that’s rewriting what’s possible in heat pump performance.

Unlike AI-based or weather-curve controls, COP Angel operates as a closed-loop system, using built-in return temperature sensors to balance and fine-tune every radiator dynamically. It knows exactly which room is underperforming and adjusts until the entire system runs in perfect equilibrium. Why this beats weather curves:Weather compensation predicts what flow temp should be; COP Angel measures what’s actually happening in your emitters and rooms, then corrects it - so it works in real buildings, with real occupancy and internal gains.

The result?
Higher COPs (by running cooler, longer, and at lower compressor speeds), lower running costs, lower installer skill requirements, simplified commissioning, and a consistent user experience that’s simply unmatched. In lab examples, operating at 35 °C vs 50 °C delivers ~32% efficiency uplift, and further modulation down to minimum power adds ~13% more - pointing to 30-40% total savings potential when these effects are combined in practice.

We’ve shared COP Angel with manufacturers, distributors, and control developers across the globe. The feedback is always the same - "this is the future."

After successfully proving this with a digital twin, we are building the first hardware and software prototype.

The question is... who will be first to disrupt the market with it and bring heat pump technology to the masses?
