After a gas boiler burst in her roof, Lou Aitken decided to electrify her home and install a heat pump hot water system. Despite the best intentions, following through on them was surprisingly difficult. While her centralised gas radiators are relatively unique in New Zealand and therefore more expensive to retrofit than the average home, there are plenty of lessons in her piece for those wanting to follow suit. As she says: "We know that we need to electrify our homes, electrify the machines that fuel our lives. But the system needs to be supportive and ready now, not in 2030 and not by 2050. Our planet depends on it."
