Heating technology

Heat pumps under control:
From commissioning and regulation up to maintenance and service

In order for heat pumps to reliably provide sustainable heat, and for the heating curve to be right, they have to be thoroughly checked using suitable measurement technology at regular service and maintenance intervals.

An annual service is also recommended for all heat pumps with refrigerant. This is way, efficient operation is ensured, and your customers can save costs.

Measurement technology for servicing heat pumps with refrigerant

Servicing heat pumps

With a digital manifold, you can carry out the commissioning and service of heat pumps quickly, flexibly, and precisely. Bluetooth, wireless probes and the testo Smart App make measurement and documentation easier.

  • Perform high-precision measurements in no time

  • Ensure tightness of refrigeration systems

  • Test and optimise the efficiency of the system

What customers say about Testo digital manifolds

The testo 558s offers a smartphone-like user interface, a feature that differentiates it from other models. Our company has consistently chosen Testo for the past three generations of manifolds due to their ability to adapt to industry advancements. The integrated smart app enhances usability. Specifically, the vacuum gauge's data logging directly to the app allowed for remote monitoring during system evacuation.

What else I would like to say to other installers, the device really saves a lot of time, you don't have to take as much stuff with you, you don't have to do as much yourself, because the testo 557s does everything for you.

Service technician at Lennox

In the past, we had to work with analogue measuring devices and needed a notepad, and we needed external temperature sensors. Testo has now incorporated all of this into a single device. This makes it much easier and much quicker for us to satisfy the customer with the performance of their device.

Other applications related to heating systems

Differential pressure

Checking the gas pressure on burners is one of the standard measurements during maintenance on domestic heating systems. The gas flow pressure and the gas rest pressure of the system are measured.

  • Optimum flow pressure for gas boilers in the range of 18 to 25 mbar

  • Avoid failure of the heating system
