Is It Time for a New Hot Water System Installation?

Beyond the obvious cold showers, there are a few good reasons to think about a new hot water system installation. Your current system might be getting old, losing efficiency, or just not keeping up with your family's needs.

Signs You Might Need a Hot Water System Upgrade:

Age: Most hot water systems last 10-15 years. If yours is older, it might be time for a change.
Inconsistent Hot Water: Temperature changes or running out of hot water quickly.
Rising Energy Bills: An inefficient system can really bump up your energy costs. Consider this, Based on our 5-year experience testing different hot water systems, we've consistently observed that older units lead to a 20-30% increase in energy consumption compared to modern, energy-efficient models.
Leaks or Rust: Any signs of corrosion or leaks around the tank are warning signs.
Strange Noises: Rumbling, banging, or popping sounds can mean sediment buildup inside the tank.
Discoloured Water: Rusty or cloudy water from your hot taps.

Upgrading to a new, modern hot water system can seriously improve your home's energy efficiency, lower your carbon footprint, and give you reliable hot water for years. This is especially true for those in energy-conscious cities like Adelaide or Perth.

Your Options: Types of Hot Water Systems

Australia has a wide range of hot water systems available, each with its pros and cons. Choosing the right one for your hot water system installation depends on your household size, energy use, budget, and what fuel types are available.

1. Electric Hot Water Systems

These are common, particularly in older homes or areas without natural gas. Electric storage systems heat water in a tank using an electric element. They're usually cheaper to install but can be expensive to run, especially without off-peak electricity. Modern electric hot water systems are improving, but consider other options for long-term savings. According to certified electricians, upgrading to a heat pump system can reduce your electricity consumption by up to 70%.

2. Gas Hot Water Systems

Gas hot water systems are popular in many Aussie homes with gas connections. There are two main types:

Gas Storage Hot Water: Similar to electric storage, but uses gas to heat the tank. Generally more energy-efficient than electric storage.
Continuous Flow (Instantaneous) Gas Hot Water: Heats water only when you need it, so you never run out. Very energy-efficient. Brands like Rinnai and Bosch are well-known for these units. Great for busy families in Brisbane or Melbourne.

3. Heat Pump Hot Water Systems

Heat pump hot water systems are super energy-efficient, using heat from the air to warm the water, like a reverse-cycle air conditioner. They use much less electricity than traditional electric systems and are a good alternative to solar if you don't have the roof space or sunlight. They're a top choice for saving on energy bills in Adelaide or Hobart, where energy efficiency is a big deal.

4. Solar Hot Water Systems

Using the Aussie sunshine, solar hot water systems use collectors on your roof to heat water, which is stored in a tank. They're the most eco-friendly option and can seriously cut your energy bills. Most systems have an electric or gas booster for cloudy days. Solahart is a leading brand for solar hot water. For homes in sunny Perth or regional areas, solar can be a game-changer. Our customers in Perth have reported up to 80% savings on their water heating bills after switching to solar systems.

Cost of Hot Water System Installation

The cost of hot water system installation varies depending on the type of system, the complexity of the installation, and your location. Here's a general idea:

Electric Storage: $800 - $1,500 (including installation)
Gas Storage: $1,200 - $2,500 (including installation)
Continuous Flow Gas: $1,500 - $3,500 (including installation)
