How to Choose the Right Hot Water System for Your Central Coast Home
A Practical Buyer’s Guide from Clays Plumbing

If your hot water system is showing its age — slow heating, lukewarm showers, or rising energy bills — it’s time to look at your options. But with so many types available, how do you know which hot water system suits your Central Coast home best?
Let’s break down the pros and cons of each system — gas, electric, and heat pump — so you can make a confident, energy-smart decision.
Gas Hot Water Systems – Reliable and Energy-Efficient
If your home already has a natural gas connection, a gas hot water system is often the most practical choice.
Pros:
- Fast heating: Ideal for busy households or big families.
- Lower running costs: Gas prices tend to be more stable than electricity.
- Works during power outages: Keeps running even when the lights go out.
Cons:
- Higher upfront install cost compared to electric.
- Requires ventilation and correct placement for safety.
For most homes around Lake Macquarie and the Central Coast, gas systems strike the perfect balance between performance and efficiency.
Clays Plumbing provides expert gas hot water installation with full compliance and certification.
Electric Hot Water Systems – Simple and Affordable
Electric hot water systems remain a popular option for smaller households or where gas isn’t available.
Pros:
- Affordable upfront cost and simple to install.
- Reliable and low maintenance.
- Works with off-peak electricity plans for cheaper energy use.
Cons:
- Higher running costs due to electricity prices.
- Less eco-friendly unless paired with solar panels.

Heat Pump Hot Water Systems – Eco-Smart and Future-Ready
If sustainability and long-term savings matter most, a heat pump hot water system is worth the investment.
These systems draw heat from the air (like an air conditioner in reverse) to warm your water — meaning less energy use and lower emissions.
Pros:
- Energy-efficient: Uses up to 70% less electricity.
- Ideal for solar-powered homes.
- Government rebates may apply in NSW.
Cons:
- Higher upfront cost.
- Can be slightly noisier and slower to heat in colder climates.
At Clays Plumbing, we install leading heat pump hot water systems across the Central Coast — helping homeowners save on energy while staying comfortable all year round.
Key Factors When Choosing a Hot Water System
Before you make your decision, consider these key factors:
- Household size: Bigger families = bigger tank or continuous flow system.
- Energy source: Gas, electricity, or renewable options available in your area.
- Location: Outdoor vs indoor installation, ventilation, and noise levels.
- Budget: Upfront cost vs long-term savings.
