Hot Water Specialists
No Hot Water? We Fix That.
A failed hot water system is never convenient. At Wattle Plumbing & Gas, we stock and install a range of quality hot water systems and can often arrange same-day or next-day replacement across Caloundra, Kawana Waters, Buderim, Maroochydore and surrounding areas.
We'll give you honest advice on whether repair or replacement is the better option — and if replacement is the right call, we'll help you choose the right system for your household size, energy source and budget.
System Types We Supply & Install
Heat Pump Hot Water
Best Value Long-Term
Works like a reverse-cycle air conditioner — extracts heat from the air to heat your water. Very low running costs and ideal for Queensland's climate.
- Brands: iStore, Thermann, Reclaim, Sanden, Rheem, Dux
- Up to 75% more efficient than electric storage
- Ideal if you have solar panels — can be timed to heat during the day
Featured — Best Solar-Compatible Option
Thermann Smart Heat Pump
The Thermann Smart is one of the most affordable heat pump options on the market — and the ideal choice if you have solar panels. Set it to heat during the day using your free solar energy and dramatically cut your running costs.
- Affordable entry-level heat pump with smart controls
- Pairs perfectly with solar PV — heat your water for free during peak solar hours
- Wi-Fi app control — monitor and schedule from your phone
- MEPS compliant
Jay recommends: If you have solar panels and want the cheapest long-term hot water running costs, the Thermann Smart heat pump is hard to beat.
Electric Storage Hot Water
Simple and cost-effective to install. Best for smaller households or where gas isn't available. Can be set to off-peak tariffs to reduce running costs.
- Brands: Rheem, Rinnai, Dux, AquaMAX
- 25L to 400L tank sizes available
- Simple, reliable and easy to service
Gas Hot Water (Continuous Flow)
Endless hot water on demand — only heats when you need it. Compact wall-mounted unit, ideal for families on natural gas.
- Brands: Rinnai, Rheem, Thermann, Bosch
- No storage tank — compact wall-mounted unit
- Suitable for natural gas connections only
Note: Gas hot water is not recommended for properties on bottled LPG — running costs are significantly higher. A heat pump or electric system is the better long-term choice.
