Hot water systems in Parliament House
In Parliament House and the wider 4000 postcode, more owners and body corporates are looking at upgrading to an energy efficient hot water system. With electricity prices rising and many apartments and offices running hot water all day, shifting from older gas or resistive electric units to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step.
Parliament House sits right in the heart of Brisbane, where the average household size is only 1.9 people but there are more than 8,700 occupied dwellings, most of them apartments.

Upgrading to an energy efficient hot water system can deliver real Annual Hot Water Energy Savings without sacrificing comfort.
The local climate is ideal for a solar hot water heating system. Brisbane’s mean daily solar exposure averages about 18.5 MJ/m², which is roughly 5.1 kWh of solar energy per square metre per day across the year. That strong sun helps a solar hot water system or a heat pump hot water system perform extremely well, especially when paired with rooftop solar. For many buildings in Parliament House, moving from electric hot water vs gas hot water to all‑electric, backed by solar, is becoming the preferred pathway.
Across the 4000 postcode, 48 efficient hot water systems have already been installed, including heat pump hot water installation and solar hot water installation projects. Installations peaked around 2005, with steady activity in the years either side, showing a long‑standing local interest in electrification and lower running costs. As more apartments switch to the most efficient hot water system they can fit on a balcony or plant room, demand for hot water installation and hot water repair services is only growing.
For many residents and businesses, the key questions are hot water system price / cost and ongoing savings. Typical annual bill savings in Parliament House look like this:
• Old electric to heat pump hot water system: about $350–$700 per year • Gas storage to heat pump: about $250–$600 per year • Gas to solar hot water system: about $300–$650 per year • Old electric to modern electric hot water installation with solar: about $200–$500 per year

Many locals simply want the best hot water system Australia can offer for their budget, whether that is a compact electric hot water installation, a larger solar hot water tank replacement on the roof, or a neatly tucked‑away heat pump.
When comparing heat pump vs solar hot water, it often comes down to roof access, body corporate rules and timing. In dense areas like Parliament House QLD, a heat pump can be easier to install on a balcony or in a shared plant room, while a full solar hot water vs electric hot water upgrade can deliver even lower running costs if your building has good roof space. Either way, a modern energy efficient hot water system will usually outperform an old gas or electric unit.
