Figure 4 shows the experimental building with the heating appliance, hearth and the brick wall in
the garage which complies with Part 3.7 Fire Safety of the National Construction Code Volume 2.. Rain
water from the downpipe is collected in 200L drums that is stacked on top of 200L metallic drums. The
flat‐belt solar collector could heat the water in the upper drums before it is stored in lower drums. This
water will then be heated by the wood burner and circulated to a floor‐standing finned‐tube radiator‐
convector (RC) to heat the living area to the day heating thermostat of 20°C, after which it can be stored
in 1‐cubic meter tanks for use as domestic hot water.

Figure 5. Temperature measurements (markers) with IR temperature indicator
Figure 5 shows the temperatures measured in the winter month of May 2019. The 50m‐deep U‐
tube heats the water in a 200mL storage drum at 15±0.5°C. The temperature at the top is hotter than
