Frequently Asked Questions
Which Digiheat model is right for my spa?
Choose your model based on your spa size, usage frequency, and desired heating time. Smaller spas may only need a 2.4kW–4.8kW heater, while larger swim spas or plunge pools may benefit from the faster heat-up time of an 18kW or 24kW three-phase model.
Can the Digiheat be installed outdoors?
Yes. The Digiheat has a weatherproof cabinet suitable for outdoor installation. It’s designed to withstand Australian outdoor conditions when installed according to the manufacturer’s guidelines.
Is the titanium element worth it?
Absolutely. The titanium coiled element is highly resistant to corrosion from chlorine, salt, ozone, and spa chemicals like baquacil or iodine — making it ideal for long-term use and reliability.
What’s the minimum flow rate for operation?
Single-phase models (2.4kW to 6.0kW) require a minimum flow of 100 L/min. Three-phase models (18kW and 24kW) require 250 L/min. Ensure your circulation pump can meet this requirement.
Does the Digiheat come with a controller?
Yes. All models include an integrated LED digital control panel that shows water temperature and allows easy setpoint adjustment. It also displays diagnostic codes in the event of a fault.
Can I install this heater myself?
While plumbing is straightforward, electrical installation must be carried out by a licensed electrician to comply with AS/NZS standards and ensure warranty coverage.
What’s the warranty on Digiheat heaters?
Residential installations are covered by a 2-year warranty. For commercial applications, a 1-year warranty applies. Refer to Waterco's warranty booklet for full terms and conditions.

HeaterFix gave us great service in replacing our Hurlcon HX120 spa heater. We didn’t expect to see it until November, but it arrived in a week and is installed. Well done Jason.

He had our Pool Heater installed a few weeks ago, and the advice on the best location and positioning was more than just fit and leave it was working within the space and surroundings to suit our needs. Price is important, but you always remember the quality. Thank You.
