WIKA – YOUR RELIABLE
PARTNERsupport your transformation with a broad portfolio of

Heating technology is undergoing a profound change.

with more than 100 development engineers. Together

The industry is switching to climate-neutral energy

sources and sustainable systems. It is driving forward

the electrified supply of heat and hot water generated
from renewable energies as well as the use of hydro-gen, geothermal and solar thermal systems. Ever more
intelligent and efficient heating systems are developed
to conserve resources, extend the service life of thetechnology used and enable networking with otherbuilding systems.

innovative and high-precision products, IIoT solutions
and services, which we are continuously developingwith our global service and distribution network andour own production, we offer smart, efficient, andsustainable top quality for your requirements.

In this way, we can continue to grow together.

That is “Smart in sensing” and you can rely on it now
and in the future.

COMPETENTRELIABLE
HIGH PERFORMANCE

Efficient and sustainable
Private homeowners, local authorities, residential

and commercial property companies – they all needheating systems for their buildings that are efficientand fulfil climate targets.

WIKA supports you, as a manufacturer of heating
systems, combined heat and power plants andheat pumps, in partnership and cooperation, withthe appropriate measurement technology. In future-oriented heating systems, energy use and operation
are optimised by smart control systems based on

IIoT technologies. The intelligent sensor technology

can be easily configured via bus systems or wirelesscommunication and adapted to the respective
situation.

Users receive information on the processes in realtime. They can centralise their monitoring to save timeand money, and access all relevant data remotely via

an app. Just because they do not fully comply with thechanged legal regulations, existing systems do notnecessarily have to be replaced. Many of them can beconverted to a more sustainable heating.

WIKA helps you with the task of making your heating
technology smart. In addition to our wide-ranging
portfolio, we work closely with you to develop

individual devices, components and accessories.

The close collaboration between our development

experts, our in-house test laboratories and our highly
flexible production facilities leads to the desired
solutions without any loss of time.

Individual design
WIKA enables the individual configuration of yourproducts. The possibilities extend from the specificdesign of the dial and numerous options for thegeometry and colour of the case to labelling.
Optimum inventory control
As a customer, we offer you a Vendor Managed
Inventory (VMI). With this method, we take re-sponsibility for your stock levels and ensure timely
replenishment to the required extent. We take into

account both your current and future requirements.

Packaging to your wishes
We also fulfil your wishes when it comes to packaging for shipping. You decide on the nature andscope of the documentation to be enclosed. This

also applies to the labelling, which can be provided
either with barcode or with 2D code.

SOLAR THERMAL SYSTEMSThe sun is the biggest supplier of energy to the earth, and provides the starting point for an environmentally sound way to obtain energy: solar thermal energy. To supplement a gas, oil or electricallypowered heating system or as a constituent element in an ice storage heating system, a solar plant

converts free solar power into heat. To achieve a regular plant service life of 20 to 25 years, every single
component needs to be manufactured to a high quality standard.
As a collector or storage sensor, we recommend the
