Electrification in LangwarrinStart with the board, finish with the cooktop
The typical Langwarrin house from the 1960s to the 1980s has a familiar set of gas appliances: a ducted heater in the roof, a hot water tank on the side wall and a cooktop in the kitchen. Each can be replaced with an electric version that costs less to run. Reverse cycle heats for around a third of the running cost of gas heating, and a heat pump makes hot water with about a quarter of the energy of a gas storage tank.
Before any of that, we look at the switchboard and the supply. Langwarrin has both single and three-phase streets, and older boards often need an upgrade to carry new circuits for the heating, the hot water and the cooktop. Doing the board once, sized for the whole plan, saves paying for it twice.
Home electrification Langwarrin owners take on is usually staged. The heater or the tank goes first, often because one has failed, and the rest follows as budget allows. At a busy Langwarrin family home we went further in one go, designing 21.85kW of solar, a 45.2kWh battery, a heat pump and an EV charger as a single system. More on our Langwarrin page.
