  * Reuse of equipment is placed higher on the [https://en.wikipedia.org/wiki/Waste_hierarchy Waste Hierarchy] ladder, than Recycling or Disposal.
  * The computing power could be used for the common cause, by calculating for science projects using [https://boinc.berkeley.edu/ BOINC].
+ * The use of computers allows advanced smart management; for example only heat when prices are low or scale down heating (computation) to a lower level.

-I have an old PC with additional GPU, how-ever running this at full capacity does not yield enough heat to fully heat my home, so I properly needs to be running multiple machines and do not mind the extra noice.

+= Costs =
+Environment costs are a factor to consider when switching to full electric power. Yet what does it cost? Tarifs for The Netherlands are listed:
+ *  1kWh electricity costs 22ct (5ct w/o VAT)
+ *  1m3 natural gas costs 68ct (20ct w/o VAT)
+
+1m3 natural gas produces roughly 37 MJ of heat, 1kWh electricity produces roughly 3.6MJ, thus you will need 10kWh electricity to produce the same amount of heat as 1m3 natural gas.  
+
+Thus the overall comparison yields:
+ *  10kWh electricity costs 220ct (50ct w/o VAT)
+ *  1m3 natural gas costs 68ct (20ct w/o VAT)
+
+Heating with electricity in the Netherlands is 3.5 times more expensive than natural gas. How-ever since natural gas is 'deprecated' the prices are expected to rise steady where-as prices for electricity are going down.

+= Why not use ... = 
+ * [https://en.wikipedia.org/wiki/Air_source_heat_pumps Air source heat pump]; They make quite some noise and annoy the neighbours. 
+ * [https://en.wikipedia.org/wiki/Geothermal_heat_pump Geothermal heat pump]; Large investment and not scalable without good planning and coordination with neighbourhood.
+ * [https://en.wikipedia.org/wiki/District_heating District heating]; Transporting excess heat requires a large infrastructure, spending the same amount on improving the electricity grid allows for more re-use possibilities.
