The Heaty Mobile from UWS Technologie combines mobile water treatment with up to five days of autonomous operation. Three HVAC contractors share how this portable filling unit makes their everyday work easier.
Not every service call takes place under ideal conditions. Confined boiler rooms, hard-to-access rooftop plant rooms and basement spaces without an accessible power outlet are all part of everyday life for HVAC professionals. At the same time, heating water often needs to be replenished following repairs, component replacements or routine maintenance. Even when only small volumes of water are required, it is essential to maintain the required water quality.
The Heaty Mobile provides a compact solution for these tasks. This portable filling unit enables guideline-compliant treatment of small filling and make-up water volumes and can be easily transported to the point of use. Thanks to its integrated power supply, the unit can operate autonomously for up to five days, making it independent of an external power source.
Three HVAC contractors share their experiences and show how this combination of compact design, ease of use and independent power supply performs in everyday practice.

Less effort during maintenance and service work
At Solarteam Ostsee, maintenance and service work on heating systems, heat pumps and solar technology are part of the daily business. Managing Director Sven Kohlmann mainly uses the Heaty Mobile when heating water needs to be replenished following maintenance or minor repairs.
“We mainly use it to top up heating water, particularly during routine maintenance or when carrying out minor work on existing heating systems. When only small volumes of water need to be added, the unit is quick to set up and saves us time.”
In addition to its quick readiness for use, Kohlmann appreciates the compact design and straightforward operation. The unit is easy to transport and can be used without difficulty in narrow stairwells or small plant rooms.
These advantages are particularly noticeable during service calls. Contractors looking after several systems a day benefit from a solution that takes up little space, can be connected quickly and requires minimal preparation.
Independent of power outlets during service calls
The SHK 24h Kleinow specialist heating and plumbing company also uses the Heaty Mobile regularly after repairs, when replacing pumps or fittings, and during maintenance work. In apartment buildings and properties with individual apartment heating systems, it is particularly important to transport the necessary equipment to the point of use without unnecessary effort.
Master HVAC technician Ingo Kleinow therefore highlights the unit’s portability:
“We mainly use the Heaty Mobile after repairs, when replacing pumps or fittings, and during maintenance work. In apartment buildings and properties with individual apartment heating systems, we often have to work across several floors. Being able to carry the unit with us and use it directly on site is a major advantage.”
The integrated power supply also eliminates the need to find a suitable power outlet. There is no need for an extension cable when an appropriate power source is unavailable at the installation site.
“In the past, we sometimes had to look for a suitable power outlet or use an extension cable. That is no longer an issue. The Heaty Mobile is ready to use straight away, and that saves valuable time during service calls.”
This makes mobile water treatment even more flexible. HVAC contractors can use the unit wherever it is needed without having to adapt their work to the availability of a local power supply.
Reliable water quality even in confined spaces
Treiber Haustechnik serves residential and commercial customers in the fields of heating, plumbing and energy technology. In addition to new-build projects, modernisation of existing systems and work on heat pumps are important parts of the company’s business.
Master HVAC technician Daniel Treiber mainly uses the Heaty Mobile for smaller systems and modernisation projects. Whenever water needs to be replenished or a system refilled following work, he values a solution that can be transported to the point of use without unnecessary effort.
“We use the unit whenever water needs to be added to a heating system or heat pump, or when a system needs to be refilled after work has been carried out. Particularly in small plant rooms or rooftop plant rooms, we want to avoid carrying heavy equipment or long cables.”
For Treiber, the technical features are just as important as portability. The resin status indicator helps him monitor the exhaustion of the mixed-bed resin, making it easier to assess whether the treatment medium still has sufficient capacity.
“The resin status indicator gives us confidence while filling the system. We also know that we are consistently introducing treated water into the system. This makes our work easier while helping us maintain water quality in accordance with the applicable guidelines.”
The Heaty Mobile therefore combines two requirements that are equally important in everyday service work: straightforward handling on site and monitoring water quality during filling.
Compact technology for professional use
The Heaty Mobile was developed for the small filling and make-up water volumes regularly required during maintenance, repairs and modernisation work. Its features support controlled and reliable water treatment.
A pressure-independent flow regulator ensures consistent conditions during filling. The integrated LED measuring cell indicates the exhaustion of the mixed-bed resin. Additional components, including a screen gasket, non-return valve and water meter, complete the equipment for professional use.
The integrated power supply further expands the unit’s range of applications. With up to five days of autonomous operation, the Heaty Mobile can also be used in locations where no suitable power outlet is accessible. This makes work easier in basement rooms, loft spaces, service shafts and on construction sites, for example.
The key lies in the combination of compact design, controlled water treatment and an independent power supply. HVAC contractors can bring the required equipment directly to the point of use, without having to transport extensive equipment for small filling volumes or arrange a power supply in advance.
Greater flexibility in heating water treatment
The experiences of the three HVAC contractors demonstrate what matters in a mobile solution for service work: the unit must be easy to transport, quick to set up and reliable even in confined conditions. At the same time, maintaining the required water quality must remain a priority.
With its integrated power supply, the Heaty Mobile takes mobile heating water treatment a step further. It combines on-site water treatment with up to five days of autonomous operation, reducing additional effort during maintenance, repair and service calls.
For HVAC contractors, this means greater flexibility on site and a practical way to treat even small filling and make-up water volumes efficiently and in accordance with the applicable guidelines.
