Every time someone hears the word “heat pump,” a few myths follow.
Some say they’re noisy.
Some think they stop working in winter.
Some believe they need constant maintenance.
At Knaps, we’ve heard them all and we’ve also spent years proving them wrong.
Here are five of the most common misconceptions about heat pumps — and the truth behind them.
1. “Heat pumps make too much noise.”
This one might have been true decades ago not anymore.
Modern heat pumps, especially those built by Knaps, use low-noise rotary compressors, brushless DC fan motors, and precision balancing to ensure smooth, quiet operation.
In most cases, the sound level is below 50 dB that’s quieter than a normal conversation.
So if you can live comfortably with a ceiling fan running, you can live even more comfortably with a heat pump working silently in the background.
Truth: A Knaps Heat Pump is designed to hum quietly, not shout for attention.
2. “Heat pumps don’t work in cold weather.”
Another classic myth.
Many people assume that heat pumps only work in warm conditions because they “take heat from the air.”
In reality, modern inverter-based heat pumps can extract heat even from cool air right down to about 5°C efficiently.
In India, that covers 95 percent of our weather conditions year-round.
Even on cold mornings, there’s always energy in the air and your Knaps system knows exactly how to use it.
Truth: Heat pumps thrive in Indian winters. The air may feel cold, but there’s still plenty of warmth to harness.
3. “They need constant maintenance.”
This one confuses people who compare heat pumps with gas geysers or boilers.
Traditional systems use combustion, fire, soot, and scaling all of which require regular cleaning.
Heat pumps don’t.
They use refrigerant circuits and sealed systems, meaning the main components stay protected.
Maintenance typically means just:
- Cleaning air filters occasionally,
- Checking water line joints for leaks,
- And an annual inspection for safety and performance.
That’s it.
Truth: A Knaps Heat Pump doesn’t demand maintenance it just deserves a five-minute annual check.
4. “Heat pumps are complicated to use.”
Actually, they’re designed to be simpler than any conventional water heating system.
With a Knaps unit, you set the temperature once and the intelligent control system takes care of everything.
It automatically regulates operation based on ambient conditions, ensuring steady hot water supply without manual intervention.
Our IoT-enabled models can even be monitored and adjusted remotely via app or control panel.
Truth: Using a Knaps Heat Pump is easier than using your phone alarm. One touch, set it and forget it.
5. “They’re not made for Indian conditions.”
This might be the biggest myth of all and also the easiest to debunk.
Knaps designs and builds its systems in India, for India.
That means:
- They handle voltage fluctuations,
- Adapt to hard water,
- Work efficiently in humid coastal areas and dusty inland regions.
We test our units beyond standard benchmarks because Indian conditions demand it.
Truth: Knaps Heat Pumps are Indian at heart and world-class in performance.
The Real Picture
Every myth hides a missed opportunity and in this case, it’s the opportunity to save up to 80% on energy, eliminate gas dependency, and enjoy reliable hot water all year.
Heat pumps aren’t the future anymore they’re the present that’s quietly redefining how India thinks about comfort and sustainability.
At Knaps, we believe clarity builds confidence.
And when you see the science behind the silence, the savings, and the sustainability the myths don’t stand a chance.
