We built our house specifically to not have mains gas. Large double-glazed picture windows on the north side of the house, Solar and a Battery, decent insulation. Large capacity reverse cycle A/C with the condensers on the south side of the house.
The a week before handover, the Site Supervisor told us that they ‘mistakenly’ budgeted for “electrical assist” hot water instead of full electric. They would need to add Gas, but they would pay for the connection. We argued with them. They argued back. It escalated all the way to the CEO of the Building Company. The Site Supervisor kept insisting that it was impossible to have full electric hot water, that is was cost-prohibitive to install, cost-prohibitive to run and anyone who would not want gas hot water was a fucking idiot. The CEO explained to the Site Supervisor that his own house had Full electric, two Tesla Power-walls and an extensive solar array and hadn’t had to pay for Gas or Electricity since it was built. He then calmly fired the Site Supervisor and instructed the Regional Manager to authorise the Full electric hot water with no extra charge to us.
