About Us & Hurlcon / Astralpool Gas Heater Services

As a former Hurlcon / Astralpool Research & Development technician, we know these heaters inside and out! We also cover all warranty and service issues directly.  All spare parts available. We carry almost all spare parts in the Service Vehicle, so where possible, we can get it up and running on the first visit.

Astralpool / Hurlcon Pool Heaters

Hurlcon Astralpol HX 70 / 120 / WX


 The hardiest of the Hurlcon heaters ever made. Very simple. Almost identical to the old Hendy hydronic boilers. (Hurlcon bought Hendy) These heaters have been almost identical for nearly 20 years. We can retrofit circuit boards on some of the older, rare models.
Models:  HX 70 / HX 120 / HX 150 / WX Series  

Hurlcon Astralpool MX Series


 These were based on Purex MiniMax / Triton models. Many models had plastic headers that warped up against a mild steel heat exchanger. If a gasket was pinched, or when the plastic warped or cracked, water leaked and corroded out the mild steel. We fix these where possible. Some are too far gone. It’s best to let us have a very good look at them.
Models:  MX 150 / MX 200 / MX 250 / MX 300 / MX 400  

Hurlcon Astralpool Viron Series


These are designed as an extremely efficient heater. They are extremely sensitive to water flow and gas pressure issues. Many of these expensive heaters are destroyed due to poor water flow on variable speed pumps, chemical damage, and chemical location. Condensation can also be a problem with these heaters.  See more Notes Below:
Models:  Viron / Viron eVo 250 / 350 / 450 / 500 / 550  

Astralpool Jacuzzi HiNRG

Astralpool HiNRG Heater Service & Repairs

 The newest of the Astralpool/Hurlcon / Jacuzzi gas heaters. These have had some ‘teething’ problems, but are proving to be a popular heater. Very easily installed indoors. There have been several improvements over the early models. Newer models are far superior over the early models.
Models:  HiNRG 175 / HiNRG 250 / HiNRG 400 aka Jacuzzi  

Hurlcon Astralpool JX 130 & 160

Hurlcon Astralpool JX Heater Repairs and Service

Hurlcon Astralpool Viron Issues:
Due to the Viron heater's extreme efficiency, they can have a few more tedious problems, similar to higher-end cars.  We see many issues caused by water & gas supply. We've listed some symptoms and causes below. Note that some symptoms can be caused by more than one thing. 

Symptoms of Gas Supply Issues:
- sooting heat exchanger
- burnt heat exchanger
- rumbling or whining of heater

- blocked condensate tank

Symptoms of water issues:

- corroded brass plugs & sensors

- corroded or overheated heat exchanger

- blocked heat exchanger

- leaking manifolds

Symptoms of water flow issues:

- overheated, burnt heat exchangers

- leaking manifolds

- boiling / banging of the heater

Symptoms of air supply issues:
- blocked condensate tank

- damaged heat exchanger fins 

- damaged firebox insulation

- damaged blower assembly

Many issues can almost be put down to "bad luck." It is best to have one of our technicians assess your heater on-site. 

MX 125 thru 500 Issues:

MX heaters, being based on older Minimax heaters, were a basically robust burning system. 

Early models were let down by plastic manifolds that warped, and a mild steel tube end plate. Poor water quality accelerated corrosion and warping. We see many MX heaters that have leaked over time. It's best to have these assessed in person.
