We've made our best-selling boiler even better - using the latest technology to provide a reliable heating solution for the future. Its optimum price/performance ratio makes it a really good choice. Proven quality guarantees a long service life, while innovative features increase its efficiency. All this contributes to a significant reduction in your costs.
Be prepared for a change in gas composition
Thanks to the new IoniDetect combustion control technology, the boiler itself detects fluctuations in gas composition, can adapt and always works most efficiently. This feature will be most appreciated in the future when using more environmentally friendly gas mixtures.
Innovate your system with renewables
The new ecoTEC plus provides a sustainable heating solution. Especially in conjunction with the sensoCOMFORT system controller, you can optimally adjust your heating system - and thus save both energy and heating costs. Thanks to the new installation assistant, you can ensure that your boiler always operates at maximum efficiency while providing you with maximum comfort. For greater sustainability, you have the option of adding various flexible options to extend your system with renewable energy sources: solar heating, heat pumps or ventilation systems with heat recovery. Their common eBUS communication language allows easy installation and control of the entire system.
Remote control for greater convenience and efficiency
There are only a few steps to control your new heating system via an online app from anywhere. You need to add the sensoNET internet module to your boiler, which you can connect seamlessly with your boiler using the plug-and-play system (i.e. it works as soon as it is plugged in) and download our free app. You can then control it, for example, when you go on holiday. This option is not just for your convenience. Because your heating only runs at full blast when you actually need it, you save energy, your costs and the environment.
Convenient heating monitoring
Do you like to be in control of your energy consumption? Especially in combination with the sensoCOMFORT system controller, you can comprehensively control your boiler and have detailed consumption data at your disposal. Thanks to the new user interface with touch elements, monitoring the boiler operation becomes more convenient than ever. Enjoy our modern design and user menu for intuitive and trouble-free operation.

VAILLANT sensoCOMFORT 720
Our new sensoCOMFORT equithermal controller gives you complete control over your heating system and is intuitive and intelligent. Combined with our web-based sensoNET module and sensoAPP app, it allows you to control your heating - at home and on the move.
Customise your comfort with a few clicks
Thanks to the new high-resolutionsensoCOMFORT display and 3.5-inch screen, operating your heating is more convenient than ever. Six touch buttons, convenient scrolling and a backlight function simplify operation even in dark areas. Quick navigation and set-up is made possible by a clear menu structure and customisation of the heating system using the installation assistant function. And if you're missing any information, use the help button. With the sensoAPP app on your smartphone or tablet, you can control the heating from anywhere using a wifi connection: set precise temperatures, define time intervals down to the minute and use other special features such as absence mode.
Enhance your heating system with renewables
From solar systems to ventilation. With the sensoCOMFORT smart controller, you get future-ready system control. The controller is optimized to control all components of the heating system simultaneously and you can conveniently adjust the system according to your needs, e.g. domestic hot water. The sensoCOMFORT controller gives you the possibility to handle several heating circuits and therefore more complex heating systems, such as in multi-family houses.
Synchronised system design for maximum ease of use
Our new generation of gas boilers and controllers (including the sensoCOMFORT controller) have one thing in common:a harmonised menu structure, including the sensoAPP application. So, just by navigating one menu structure, you are familiar with all of them, which certainly makes operating your new heating system easier.
Designed for your modern home
A system controller should be a natural fit for your interior. The modern design is eye-catching and recognisable as it resembles modern smart devices. Thus, it integrates perfectly into modern living spaces. The same applies to our sensoAPP app. It follows on from the previous multiMATIC app - which won the Red Dot Design Award.

Frequently Asked Questions
- How exactly do I choose the right output for a VAILLANT condensing boiler? The basis is the calculated heat loss of the heated building (most reliably taken from project documentation or an energy certificate). If you don't have a project, you can roughly estimate around 60-100 W per m² of floor area for a typically insulated house built after 2000, or 100-150 W/m² for an older, uninsulated house - the exact figure varies depending on the number of floors, ceiling height, number and quality of windows, and building orientation. An oversized boiler switches on and off more often (so-called cycling), which shortens its lifespan and reduces efficiency; an undersized boiler, on the other hand, cannot keep the house warm enough on freezing days.
- Why is a condensing boiler more economical than a conventional one? A condensing boiler additionally uses the heat hidden in the water vapor produced during gas combustion - in a conventional boiler this escapes unused through the flue, while in a condensing boiler it is cooled below the so-called dew point, the vapor condenses, and the released heat is returned to the heating circuit. Thanks to this, condensing boilers achieve an efficiency of approximately 105-110% relative to the calorific value of the gas, compared to the usual 85-92% for conventional boilers.
- What type of flue gas venting does this boiler need? Most modern condensing boilers are so-called turbo boilers (with a sealed combustion chamber) and require a concentric (coaxial) or separate flue gas exhaust and combustion air intake routed through an external wall or roof - meaning no functioning chimney is needed. The exact type and maximum length of the flue (based on a diameter of 60/100 or 80/125 mm) can be found in the technical documentation for the specific model, or you can consult our customer service.
- What does the ErP energy class listed for the boiler mean? This is the mandatory efficiency labeling of heating appliances under the EU ErP (Ecodesign) directive, similar to energy labels on refrigerators. Condensing boilers commonly achieve class A, or even higher when combined with room control (e.g. A+ when using equithermal control and a room thermostat).
- How does a combi boiler with instantaneous DHW heating work? When there is a demand for hot water, the boiler temporarily switches priority from heating to heating the water flowing through the built-in plate heat exchanger - hot water is thus available almost instantly and in unlimited quantity, but the heating output is limited by the instantaneous flow rate (usually sufficient for one simultaneous draw-off point, e.g. a shower).
- Can I install and connect this boiler myself? No. By law, connection to the natural gas supply, the electrical network and the flue gas exhaust may only be carried out by a person with the appropriate authorization (most often an authorized service technician of the given brand or a gas equipment inspection technician). After installation, the boiler must be commissioned by the manufacturer's authorized service, which is usually also a condition for the warranty to be valid.
- What about servicing and warranty? Most manufacturers require a regular annual service inspection by an authorized service provider in order to maintain the warranty even after its standard expiry (an extended warranty with regular servicing is common especially with brands such as Vaillant, Protherm and Viessmann). The exact warranty conditions can be found in the warranty certificate supplied with the boiler.
- What is included in the delivery of this specific product? The exact package contents (the boiler itself, or a hot water storage tank, room control and other accessories in the case of a set) are listed in the product name and in its technical parameters above on this page.
