Utilize the district heating: Pay less for the same

In Denmark we have been heating households with district water heating since the 1920’s. Not surprisingly the consumption rose during the industrialisation in the 1950’s and 1960’s and has been high ever since. 

District heating the sustainable way

District water heating is an inexpensive heating method and combined with heat pumps it turns out to be the most environmentally friendly heating method. Buildings are responsible for approximately 40% of EU energy consumption – including the ”invisible” and non-intended consumption when buildings are shut down and should not be running. In 2020 large amounts of money are still spent on empty and incorrectly operated buildings all over the world. 

ReMonis purpose is to solve challenges like these.

Cooler than intended

The black graph on the figure indicates how good the users of certain buildings are getting the most out of the district water heating. Secondly, this figure shows how a group of users are getting significantly less value for money over time. 

Less value for money reflects, that the users ends up with a colder building than intended needing an extraordinary amount of energy to heat a room up to the desired temperature. A falling energy efficiency makes the Facility Manager pay for an energy consultant, who will examine the current operation status to find and fix the errors. The black graph on the figure indicates the large effect of an energy consultant audit – but also how the improved efficiency will continue to decrease if the audit is not repeated frequently.


Effective audits

Energy services are effective until the installations are temporarily turned off – this leads to an unintended resetting. A resetting of the systems affects how the installations are operated, which

In comparison with the black graph, the green graph on the figure indicates the effect of energy monitoring provided by ReMoni. This comparison should be interpreted considering time spend finding the mistakes vs. the documented improvement over time. ReMonis coherent solution provides a consumption overview in real time based on the single units. For a Facility Manager it does not become easier to act on facts.

In small operations detecting abnormal operation is doable. In large operations it gets complicated.

A valuable overview

When it comes to reduced consumption, you should be aware of on- and off-switches. When placed across units these can easily be affected by energy services or a power outage. In large buildings it also pays off to be aware if the heating is distributed through multiple inputs in the grid for district water heating.

A solution that pays off within the first year

ReMonis concept is the only of its kind. It consists of three elements:

  • A sensor installed onto your water pipes or power cables
  • A gateway to receive data from the sensor
  • A cloud-based platform where you access your district heating consumption

This solution provides you with constant access to actual consumption data on your current and historical consumption – updated as often as every few minutes. Act on facts to precede costly mistakes.

Prevent penalties on your district heating

Spar på fjernvarmen

District heating and cooling are worth a lot of money.
Prevent wasting money on additional bills with the right insight.

Spend the money right: Avoid getting an additional district heating bill by ensuring the right temperature on your return water.

As a commercial district heating customer you automatically return heated water to the heating plant after using it. If your return water happens to be too hot, there will be an energy loss. The raised temperatures require more water to produce the same amount of energy as with colder water, whereas you risk getting an extra bill.

When the temperature of the return water is too hot, the heating plant can do two things to ensure enough hot water for all:

  • They can send more water for district heating into the grid, and thereby in circulation, which will result in a raised energy consumption. Otherwise:

  • They can raise the water temperature, which will result in a raised energy loss in the grid.

After all, optimal cooling can both save you and your surroundings for resources. 

If you manage to deliver cooled return water, the heating plant will need to warm up a smaller amount of water before forwarding it to the next consumer. If your return temperature is low, the cooling is good. In this case you have been good utilizing the energy, maybe based on temperature insights, and you will save the expenses on an additional bill.

Buildings are responsible for approximately 40% of the total energy consumption.


Monitoring your cooling is a good investment

Expenses to cooling is a significant cost in most budgets and it pays off to check up on it. Additional bills on the district heating is a reality for many businesses but could easily have been avoided with improved insights in the consumption. Knowing the temperature on the in-run and out-run enables you to adjust the water temperature before the water is sent back.

Made easy by novel technology

ReMonis temperature sensor HeatMoniSpot provides you with an overview of the temperature of both in- and out-run. By combining AI and cloud-data HeatMoniSpot provides you with a user friendly overview of the water temperature on an ongoing basis. Exact data monitoring as often as every 5 minutes makes it easy to localize the hours added to the bill marked “district water heating” – and not least act upon it.

With HeatMoniSpot you can handle the problem immediately and avoid additional bills.

Beside cooling of the district heating you can save even more by being aware of your other installations.  You can also use a HeatMoniSpot to find and fix errors of this kind. Based on data you can ensure harmony in your installations by knowing that warming and cooling at the same location are not running at the same time – and thereby save time, money and resources.  

Minimize costs and CO2-emmision with harmonious installations

Yes, it seems logical. Nevertheless, errors in operation take place every day, all year around in all kinds of buildings. Monitor to fix the error and save a lot of money.

To ensure harmonious installations you need to be especially aware of locations where heating and ventilation are both being used. When an incident such as a power shutdown occurs, the settings are often reset, and the two functions suddenly run accordingly.

Does your Building Management System turn on both functions at the same time?

Energy waste can be avoided with improved insights in your consumption – as provided by HeatMoniSpot. Acting in time can save you for a significantly raised bill.

There could be large amounts of money to safe.

HeatMoniSpot provides you with real time data insights. Act on facts.

Save energy without compromising the comfort

Tech Danish SDG

Now it will be all about comfort – sustainable comfort.  


By establishing 17 Sustainable Development Goals (SDG’s) the UN has set a strong global focus towards a more sustainable future.


The goals have been limited by lasting until year 2030. But even though, they can be difficult to act upon. At ReMoni we have found 3 concrete ideas for you to minimize your environmental footprints without making compromises on comfort. To contribute you must neither sit at a cold office nor in a darker room. Instead, have a look at these 3 ideas for a more sustainable operation.

  • Clean Energy: Goal #7

    Building manufacturing and waste reduction are complex fields of work. Do you have the complete overview of the operation costs for your buildings? The better your overview becomes, the easier you can react on abnormal operation. By implementing ReMonis PowerMoniMain
    you can monitor your energy consumption based on live data and view your data in our platform ReCalc or the Energy Management System, which you are currently using.

  • Gather your deliveries: Goal #9

    Save resources and money with bundled deliveries. By knowing that all your office deliveries are being distributed on for example Tuesdays and Thursdays only, you will of course happen to wait for your order an extra day or two. But on the other hand, you will be contributing to a lower CO2 emission every single week, all year around than if your deliveries had kept being delivered on a daily basis – as it unfortunately happens for most companies.

    Taking climate action in such a concrete way provides you with the best conditions to boost your CSR image. Do not hesitate to inform your partners and customer how you are actively supporting a more sustainable consumption.

  •  Let’s reuse: Goal #11 & #12

    On a small scale you can buy packaging, labelling and wrapping made from reused materials. On a bigger scale furniture and electronics can be found second hand – also for B2B.

    When a company is closing inventory such as desks and office chairs in very fine condition are put on sale for a reduced price. You can also find technical equipment such as keyboards and screens this way and save money and C02. If you are from a company with a green mindset do not forget to check out the options for a secondhand deal. Reuse to gain economical savings and help minimizing the global overproduction.


Minimize the C02 footprint and optimize your economy: Reduce energy waste – bundle deliveries – reuse.

Save money on ventilation

spar penge på dyre ventilationsanløg

Can you reduce your ventilation costs by 50 % without lowering the comfort?

If so, you are not alone. Related to ventilation systems we find one of the costliest mistakes. This stresses the importance of frequently checking up on the Energy Management System after services and repair of minor defects.

We do need ventilation

Recently a Danish municipal institution managed to reduce its ventilation costs by 40 % by simply checking up on the ventilation performance. The error was tracked back to a non-intended resetting of the EMS-system after a standard service. If you are responsible of one or more buildings, it is essential to have a sufficient overview. ReMonis design process of the IoT-sensors has been based on this acknowledgement to provide exactly that: A data based overview with customized data sampling available as frequently as every two minutes.

”After a defect we have had service on the EMS-system – I got the feeling that something was not operating as it should.”
– Facility Manager in a Danish Municipality up on an energy reduction of 40 %.


Ventilation in buildings prevents mold and ensures a healthy physical working environment, whereas it is necessary. The importance of ventilation is rarely on topic, but nevertheless it is an essential function inside our buildings. Overall, the ventilation system is contributing to maintain a high air quality by constantly venting in fresh air while venting out the CO2.

Do not compromise the comfort to achieve energy savings.

Stay in control

In the cloud platform ReCalc you can log in to get an overview of the current and historical ventilation consumption in your buildings. Access your consumption data in a detailed review and detect changes easily.

Thus, you can distinguish changes from the usual operation pattern and act on facts. Stay in control of your selected units and detect fluctuations when they appear with the sensor PowerMoniSpot clamped onto the cable with cable ties. Utilize the customized data sampling to optimize your manufacturing.

If you are a Facility Manager or similar PowerMoniMain help you gain overview across units and buildings. With our power sensor PowerMoniMain or PowerMoniSpot it does not become much easier: You can find errors in the EMS-system on an on-going basis. Besides, you can localize units, that could easily operate on a lower level during for example nights and weekends, where the production activity is at its lowest.


AI and cloud technology in an innovative, user-friendly solution.

ReCalc will let you know

Don’t worry if your building’s ventilation system is mismatching the settings of your EMS-system – ReCalc will let you know. ReCalc provides you with a constantly updated data review leaving you with an always updated overview. Based on this, you can localize challenges and defects in an early. By managing them in time you avoid costly surprises.


Minimize your downtime

Optimal manufacturing requires an overview – even across services


Most services are planned according to a certain time interval  This approach is quite common, even though different units do not operate equally and therefore do not show signs of wear and tear at the same time. As a result, the unit’s service interval can vary a lot which increases the importance of an overview to prevent an unwanted break down.


If you, as a professional, are employed in the production area, you must have experienced how impossible it can seem to gain an overview across the different units and get it based on a frequent data sampling going on 24/7.


A good overview is the best way to avoid a production stop.  

An overview of great value

The production units do rarely need service at the same time. For this reason, it would be essential only to perform service on the units when it is needed. Preventing wear by performing maintenance is of great value, since it prevents units from breaking down, which leaves the employees unable to do their job.


If you for example only perform services after each 6000 operation hours there is a significant risk to miss it, if a unit should show signs of wear between two services and thereby need for additional maintenance.

An overview across services

Lack of overview is expensive and so is unnecessary service.

For this reason, ReMoni is launching the power sensor PowerMoniMain, which provides you with an overview of energy consumption regardless services. Such a detailed overview is highly suitable for you as a Facility Manager where the everyday tend to be busy. With this solution you can effectively act on facts as soon as a  certain action is needed.

Utilize the capacity
You can follow the consumption of your production by following measurements from PowerMoniMain sampled every two minutes. If units which should have been closed down nights and weekends are still operating, you can rapidly detect and manage it. We call it act on facts.


On a longer term you will experience a raise in the consumption of some units as they get more and more worn out over time. After a certain number of operation hours, the units performance will be affected. You get nothing out of it – beside an increased electricity bill.

PowerMoniMain provides data sampling as frequently as every two minutes so you can take action. 

Avoid production stop

This solution makes it easy for you to spend your time as effectively as possible. Besides, this enables you to follow the operation development closely over time and exclusively summon technicians when you know that it is actually needed.


The data reading is easy and simple and in ReCalc – or ReCalc MoniTor – you have the option to set alarms. By doing this, you can gain a valuable overview in your prefered cloud platform. This makes it easy for you to take action and likely to save large amounts on money on production stop and downtime in the production.

Need for detailed insight solution

A day in 2013 Bo Eskerod Madsen got an idea. He wanted to know the exact consumption and performance for each unit, 24/7. At this time, no solution could meet that exact need, and therefore Bo developed a new measurement concept called ReMoni. The company’s DNA consist of local data sampling, which is send to the cloud where the users can access their consumption – measured over time and specifically for the single installations. What’s in it for you can best be explained with one of the sensors as an example.  

Understand the solution with PowerMoniMain as an example here.

If consumption is the challenge, PowerMoniMain is the solution.

Non-specific consumption

Do you recognize the challenge with only non-specific consumption measurements, or do you know for sure that none of your operating costs are rising year after year?
In many companies the energy account is approved without lifting an eyebrow if it is within a margin of the account from last year. As a result, the development is rarely being checked up upon, which provides a potential for large savings. PowerMoniMain is not just a product but a part of a coherent solution.

In comparison with other market alternatives PowerMoniMain is easy to install and inexpensive to acquire – and the ROI is typically only weeks. In other words, PowerMoniMain is a user friendly and effective energy meter that can help you get a detailed overview of your consumption. It enables you to check up on your consumption when you have got time for it. With this complex cloud solution, you can maintain the overview across your electrical installations with detailed monitoring presented in a user-friendly view.

Acting on facts have never been easier!

ReMonis løsning er detaljeret forbrugsmåling, der giver overblik og sparrer dig for penge.


Get an overview of the complexity in your installations by screening specific measurements. 

With 15 channels you can monitor up to 15 units in one comprehensive overview.
At ReMoni we have spent years on developing the concept behind PowerMoniMain. The reason for that is, that this meter has been created based on market insights and experience with specific production facility needs. PowerMoniMain stands out from the alternatives on the market by offering 15 channels and clamp on-installation. Overall, it has been recognized for its great potential for savings on consumption. As an ”add on” to your cost savings you are actively supporting a sustainable environment.

It’s a win-win.

When you have received your PowerMoniMain you should not clamp it onto the cables like a PowerMoniSpot but install it into the buildings switch board. We have solved the typical problem with limited space in the main switch board when designing the PowerMoniMain. It fits the switch boards by using CT-clamps mounted onto each single phase. From here data is send to ReMoni’s gateway and on to ReMoni’s cloud platform ReCalc. In ReCalc you can access your power consumption data presented in a detailed dashboard.

It becomes easy to act on facts with a PowerMoniMain.

The easy choice
In short PowerMoniMain makes it easy to examine the consumption footprint. If you need to know both power and voltage you can easily use PowerMoniMain with banana connectors with magnetic probes for the connectivity. Simply click one onto each phase terminal in the 3 phases of the switch board to receive monitoring data with a time interval of 2 seconds.

If your installations have a significant data consumption you can exchange the CT-clamps with some suitable for higher current-levels. PowerMoniMain can be adjusted to different CT-clamps  and manage op to 1200 ampere. Get an overview of the complexity in the electrical installations with quick screenings on different installations in your production. Screening measurements from PowerMoniMain provides detailed insights regarding electrical parameters such as power consumption and voltage variation. If you would like to learn more, please find our presentation of ReCalc here.

The good choice

As mentioned in the introduction, ReMoni was invented thanks to Bo Eskerod Madsen’s wish for insight in his consumption and his wish to spend the resources in the most sustainable way. After the first few years in business we are still confirmed in what we do – and that a good consumption overview is a good first step towards a more sustainable operation.
