• This type of activity is dependent on available equipment and prior competences with coding and Arduino. If these are limited conduct the experiments and track the temperature in Excel or on graph paper.

Heating systems

Educators should familiarize themselves with the principles of heating systems and HVAC terms to be able to discuss with students. HVAC is an engineering term which stands for heating, ventilation, and air conditioning.

Educators should also assess principles and performance of the applied heating system at the school and at home in order to bring perspective to the talk.

Understand these concepts before the lesson and be able to discuss them with students:

• Principles of heat transfer
• Principles of heating systems
• Power sources, ie. fuels, solar. district, heat pumps

Introduce the topic and divide the class into groups of four

Instruct each group to research a ‘heat source’ topic and a ‘distribution system’ topic.

These heat sources exist:

• Furnace
• Boiler
• Heat pump
• Solar heating
• Electric (resistance) heating
• ...

These distribution systems exist:

• Steam radian
• Radiant heating
• Hot water baseboards
• Electric baseboard
• Forced air system
• ...

Each group should present findings about the given source and distribution technology in a poster session.

Discuss pros and cons for each item and try to understand the workings of the different systems

Discuss efficiency of the systems

Try to discover energy-saving-tips for each technology. An example could be thermostats, cleaning of air filters etc.

Experiment: Effectiveness of insulation of heating pipes.

Distribution of heat throughout buildings is often done using a pipe system that carries heated water. The water is heated by the above mentioned sources and the heat is released where it is needed, for example in a radiator.

To ensure that the heat is not lost on its way to the radiator, pipes must be insulated. In fact, this is one of the most important ways to make a heating system more efficient.

Make students create a system in the Makerspace using metal pipes, for example copper pipes or iron pipes.

Setup a temperature logging system either by using an arduino system like this

Image shows suggested wiring of an Arduino UNO to obtain an temperature logger.

Documentation here: https://maker.pro/arduino/projects/make-arduino- temperature-data-logger

Or create a manual logging system using an IR thermometer and a temp/time tracking which is done in Excel by the students.

Image shows an IR Thermometer

Image shows how the Excel sheet can be constructed. A graph can be made with the time/temp values.

Use the measurements done by Arduino or the manual thermometer to create a theory about heat loss and isolation.

Image shows how to use an IR thermometer.

See https://sciencing.com/calculate-hydraulic-flow-7155002.html for references on how to calculate heat loss.
