Katoomba Cottage 2024

House Notes – Katoomba Cottage

We have electrified our traditional mountains cottage while undertaking minor renovations. This has made our home more comfortable to live in, cheaper to run and reduced its carbon emissions.

Sustainability features we included:
– ceiling and underfloor insulation. We fortunately already had wall insulation installed.
– 9.68 kW solar system
– upgrade to 3 phase power
– induction cooktop
– 7-star fridge
– LED lights
– multi-split reverse cycle air-conditioning system (mostly floor-based consoles)
– heat pump hot water system
– low VOC paint
– respraying bat, kitchen splashback and old tiles rather than removing and replacing them

We also buy 100% GreenPower renewable electricity to match our limited grid electricity usage.

We have not yet had a full year of bills but estimate we’ll save $1,200-$1,600 a year in energy savings.
