Do you repair Dux Airoheat 250L heat pumps?

Yes. We diagnose sensor and controller faults, repair the fan/compressor and booster element, and replace valves and anodes as needed.

Why is my Airoheat only giving warm water?

Common causes include thermistor faults, restricted airflow across the evaporator, low ambient conditions or a booster element issue. We test and fix the root cause.

The PTR valve keeps dripping — is that normal?

Occasional discharge is normal. Continuous flow may indicate high pressure/temperature or a worn valve. Airoheat spec shows 1000 kPa relief and 800 kPa max supply; we test and replace if required.

Can you set it up for off-peak tariffs?

Yes. We can advise and configure supply/timers so the unit heats on your cheaper tariff, subject to your meter setup.

Common Dux Airoheat Problems We Fix

No hot water / lukewarm water – thermostat/thermistor faults, restricted airflow across the coil, booster element not engaging, or refrigerant issues. We test sensors and controller wiring per the Dux troubleshooting flow. ManualsLib
PTR (TPR) valve constantly dripping – some discharge is normal, but steady flow can indicate high pressure/temperature or a worn valve; Airoheat spec lists 1000 kPa relief / 800 kPa max supply and we verify this on-site. Multiscreensite
Runs constantly / short cycles – dirty/iced coil, blocked air path (the unit needs strong free-airflow), incorrect mode/timer supply, or sensor/PCB faults. ManualsLib+1
Noise & vibration – fan bearings, debris on evaporator, loose mounts, or compressor issues; we clean, realign and replace as needed. ManualsLib
Condensate / drainage issues – blocked drain causing water around the base; we clear and re-route per the install guide. ManualsLib
Anode/corrosion & scale – we inspect the anode and cylinder to protect tank life and efficiency.

How Dux Airoheat Heat Pumps Work (and what we service)

Dux Airoheat uses a fan + evaporator + compressor + in-tank heating coil to pull heat from outdoor air and transfer it into the water, with an electric booster element as backup. The 250 L model is designed for 3–5 people and requires strong free-airflow (~1500 m³/h) for best performance; it is not suitable for alpine areas or above 1000 m elevation. We service sensors/thermistors, controller/PCB, fan & coil, compressor, booster element, anode, PTR/expansion valves and condensate drainage.

Dux Airoheat heat Pump repairs frequently asked questions

Do you repair Dux Airoheat D2FH/D2FHG 250 L units?

Yes — we regularly service and repair the current Airoheat 250 L models (and earlier variants), including sensors, controller, fan/compressor, booster and valves

Why am I only getting warm water?

Likely causes include thermistor faults, restricted airflow over the coil, low ambient conditions making the booster work harder, or an element issue. We test and restore full performance.

The PTR is dripping every few minutes — normal?

Occasional discharge is expected; a steady stream usually means pressure/temperature is too high or the valve is worn. Spec guidance is 1000 kPa relief / 800 kPa max supply. We test and replace if needed.

Can you set it to heat on off-peak tariffs?

Yes — we can advise and configure supply/timers so the unit heats when your tariff is cheapest (subject to your meter/tariff setup).

What’s covered by Dux warranty?

Dux provides product warranties (e.g., 5-year tank on current Airoheat) with additional consumer law rights; we’ll help you navigate claims if applicable.
