This FridayTech is a clarity piece for installers and distributors.
No buzzwords, no abstraction—just a precise explanation of energy-aware heat pump control and what it means in practice when comparing TAHMV R and TAHMV RH.
If you only remember one thing:
👉 RH does not change the machine. It changes how the machine understands energy.
First: What does not change
A common misconception is that RH means a new or upgraded unit. It doesn’t.
TAHMV R and TAHMV RH are mechanically identical:
- Same refrigeration circuit
- Same hydraulic layout
- Same compressor and heat exchangers
- Same performance limits and certifications
There is no additional capacity and no hidden efficiency trick.
The difference lies entirely in energy-aware heat pump control logic, not in hardware.
What RH monitors in an energy-aware system
Standard heat pumps react mainly to temperature demand.
TAHMV RH adds a higher control layer focused on energy context.
With energy-aware heat pump control, RH continuously monitors:
- Availability of self-generated electricity (e.g. PV surplus)
- Grid import versus self-consumption status
- Time-based energy conditions (tariffs, peak windows)
- Thermal flexibility of the system (how much heat can be shifted in time)
These are energy signals, not room thermostats.
RH looks at energy conditions first, then decides how and when to deliver comfort.
What RH reacts to
Monitoring alone changes nothing unless the system can act on it.
TAHMV RH uses energy-aware heat pump control to adapt operation automatically, for example by:
- Advancing heat production when electricity is abundant
- Postponing non-critical cycles when energy is scarce or expensive
- Prioritising thermal storage over instant heat delivery
- Smoothing compressor operation to align with energy availability
The outcome is not more heat—but better-timed heat.
This is the core shift:
From temperature-driven operation
to energy-aware heat pump control.
What the installer does not configure
This is where RH is especially relevant for installers.
With TAHMV RH, installers do not need to:
- Program energy strategies
- Define PV or tariff logic
- Create custom schedules or rules
- Tune or manage algorithms
Commissioning remains exactly the same as with TAHMV R.
Energy-aware heat pump control operates above the installer layer:
- Stable
- Automatic
- Predictable
In short:
👉 RH adds intelligence without adding installer complexity.
Why this matters for installers and distributors
Energy conditions are changing faster than installation standards.
End users increasingly ask:
- “Can the heat pump use my solar power better?”
- “Can it avoid peak energy costs?”
- “Is it ready for future energy volatility?”
With heat pump control, TAHMV RH allows you to answer yes—
without increasing installation time, risk, or after-sales complexity.
It preserves:
- Installation simplicity
- Commissioning reliability
- Long-term system stability
While upgrading the control logic to match how energy actually behaves today.
In one sentence
TAHMV R delivers heat efficiently.
TAHMV RH decides when heat makes the most energy sense—using energy-aware heat pump control.
The difference is subtle at installation, but decisive over the system’s lifetime.
Next FridayTech: why heat itself is the most robust form of energy storage—and why batteries are only part of the story.
