Heating in MordiallocTall rooms, old heaters and hot upstairs bedrooms
Mordialloc homes fall into three groups, and each one is uncomfortable in its own way. The Edwardians and Californian bungalows have high ceilings and draughty rooms that swallow heat, usually served by a gas heater that has been added and replaced over the decades. The 1950s and 60s brick and weatherboard houses have a gas wall furnace or a ducted heater and not much else. The newer townhouses are well sealed, but the top floor bakes in summer and the single ducted system cannot tell upstairs from downstairs.
Reverse cycle suits all three, in different forms. A period home with rooms off a central hall is often best served by a multi-head, with a unit sized for the volume of each room. A single-storey postwar house with a clear roof space takes ducted reverse cycle on new R1.5 insulated ducts. A townhouse usually needs its levels controlled separately. In every case the gas heater is replaced by something that costs around a third of the running cost of gas heating and cools the house as well.
The bay is the other factor. Salt air reaches the streets near the beach and the creek mouth, and blocks are narrow, so where the outdoor unit goes and how it is protected matters more here than inland. We sort that out at the site visit, along with the rest of what we do in Mordialloc.
