With Testo, you are optimally equipped for all tasks in your work on all heating systems - allowing you to do your job professionally, reliably, and quickly!
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.
With a testo Smart Digital Manifold, you can carry out the commissioning and service of heat pumps quickly, flexibly, and precisely. Bluetooth, testo Smart 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 optimize the efficiency of the system
What else I would like to say to other installers, the device really saves a lot of time, performs a variety of functions, and can automatically calculate values, making even the most complex tasks, simple.

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

My first impression is very positive; the testo 557s is a Smart Digital Manifold, a valuable addition which you won't regret as a HVAC technician. I don't think any other brand can compete.

Checking the gas pressure on burners is one of the most common measurements during maintenance on home heating systems. The differential pressures of the gas is measured.
Optimum flow pressure for gas boilers is in the range of 18 to 25 mbar
Avoid failure of the heating system
