Residential Heating Systems in Victoria

What Works, What Doesn’t, and What We Recommend

In Victoria, heating is not about achieving a number on a thermostat. It’s about how warmth is experienced — evenly, quietly, and without the home feeling dry, noisy, or mechanically driven.

Melbourne’s climate is defined by long, cool winters, sharp temperature swings, and short but intense cold snaps. A good heating system works with the architecture of the home, not against it. A poor one compensates for design decisions that were never resolved early.

This article outlines the main residential heating systems used in Victoria, what genuinely works, where certain systems fall short, and how we approach heating design in our projects.

Start with the building, not the system

Before selecting any heating system, the most important question is not what unit to install, but how much heating the home actually needs.

In Victorian homes, heating performance is shaped first by:

• orientation and winter sun access

• insulation continuity and airtightness

• window size, placement, and glazing performance

• ceiling heights and internal zoning

• door control between living and sleeping areas

When these fundamentals are resolved well, heating systems can be smaller, quieter, and far more efficient. When they’re ignored, even the most powerful system struggles to create comfort.

At ENCLAVE, heating is always considered alongside the architectural design — not added afterward.

Reverse-cycle heating (heat pumps)

What it is

Reverse-cycle systems use electricity to move heat from outside to inside. They are commonly installed as wall-mounted split systems, multi-split systems, or fully ducted systems concealed within ceilings.

Why it works well in Victoria

Reverse-cycle heating is currently one of the most efficient and versatile options for Victorian homes. It provides:

• fast response times

• good performance across a wide range of winter temperatures

• the ability to heat only occupied zones

• compatibility with all-electric homes and solar PV

For most residential projects, particularly new homes and major renovations, reverse-cycle heating forms the backbone of a well-considered heating strategy.

Where it falls short

Performance drops when:

• zoning is poorly designed

• the system is oversized

• ducts are routed inefficiently

• indoor units are visually intrusive or noisy

Reverse-cycle heating works best when it is planned early, properly zoned, and carefully integrated into the architecture.

Hydronic heating (radiators and in-slab systems)

What it is

Hydronic heating circulates warm water through panel radiators or in-slab pipework to create radiant heat. The heat source may be a gas boiler or an electric heat-pump system.

Why clients love it

Hydronic heating delivers a type of warmth that many people describe as “quiet” or “calm”:

• no air movement

• no fan noise

• even temperature distribution

• excellent comfort in bedrooms and living spaces

Underfloor hydronic heating, in particular, suits high-end residential projects where comfort and visual restraint are priorities.

The key limitation

Hydronic systems provide heating only. They do not cool the home.

This means hydronic heating is often paired with a separate cooling system — typically reverse-cycle air conditioning or, in some cases, evaporative cooling.

Hydronic heating performs best in homes with:

• strong insulation and glazing control

• good solar management

• clients who value winter comfort over speed of heat-up

  
  

Ducted gas heating

What it is

Ducted gas heating uses a central gas furnace to heat air, distributing it through ceiling or floor ducts.

Why it’s becoming less common

While ducted gas heating was once standard in Victorian homes, its role is diminishing due to:

• rising gas costs

• the shift toward electrification

• the need for a separate cooling system

• lower efficiency compared to modern heat pumps

For many households, installing a new gas system no longer makes long-term sense when an all-electric alternative can heat and cool more efficiently.

When it can still make sense

In some existing homes with limited electrical capacity or short-term renovation plans, ducted gas heating may still be retained. However, for new builds, it is rarely our first recommendation.

Electric resistance heating

What it is

Electric resistance heating converts electricity directly into heat. This includes panel heaters and electric underfloor heating.

Where it works

Electric resistance heating can be effective in:

• bathrooms

• powder rooms

• small, infrequently used spaces

• short-duration comfort scenarios

Where it doesn’t

As a whole-of-home heating solution, resistance heating is generally inefficient and expensive to run compared to heat-pump systems.

We typically treat it as a supplementary comfort layer, not a primary system.

Fireplaces

What they do well

Fireplaces — particularly slow combustion wood fires or gas feature fireplaces — create atmosphere. They act as a visual and emotional anchor within a space.

What they don’t do

Fireplaces rarely perform well as a sole heating source. Heat distribution is uneven, control is limited, and reliance on a fireplace alone often leads to cold secondary spaces.

In contemporary residential projects, fireplaces work best as:

• a feature element

• supported by a reliable primary heating system

What we typically recommend

While every project is different, our recommendations often follow a consistent logic:

For most new homes and major renovations

Ducted reverse-cycle heating with proper zoning

This provides:

• efficient whole-home heating

• flexibility across living patterns

• clean integration with architectural design

• future-ready compatibility with solar and electrification

For higher-end homes focused on winter comfort

Hydronic heating paired with reverse-cycle cooling

This combination offers:

• exceptional thermal comfort in winter

• quiet operation

• refined, uncluttered interiors

• long-term comfort rather than short-term performance

For smaller homes or staged upgrades

Targeted split systems with strong fabric upgrades

Improving insulation, sealing, and glazing often delivers better comfort outcomes than simply installing a larger heating system.

Heating is a design decision, not a product choice

The most successful heating systems are rarely the most complex. They are the ones that are:

• sized correctly

• zoned intelligently

• integrated early

• supported by good architectural fundamentals

In Victoria’s climate, good heating should feel almost invisible — present when needed, absent when not, and never fighting the building itself.

If you’re planning a new home or renovation, heating should be resolved alongside the architecture, not added once everything else is fixed.
