Gas Pool & Spa Heaters

We try to keep every model of heater in stock where possible. Due to so many manufacturing & supply-chain issues due to Covid-19 this has made this impossible. If you're looking for a gas heater, feel free to come to our shop to discuss the various models, as we have tons of experience with them all!

Ordered by Simplicity & Robustness:

• Astralpool (Hurlcon) HX Series
  
  
• HX 70 & HX 120 - Spa Heaters - Super Robust & Simple-design. Similar, proven design since the 1990s, and based on an even earlier design from Hendy Boilers. 
  
  
• Raypak (Rheem)
  
  
• Spartan 131 - Spa Heater - Super Robust & Simple-design. Similar design for over 20 years.
• Raypak Premium 280, Raypak Premum 430 - Commercial-grade, Bronze-headers, Stainless Base. The most rubust gas pool & spa heaters available. Similar design since the 1990s. 100% Proven & Reliable.
• Raypak 200, Raypak 280, Raypak 350, Raypak 430 - Super Robust with time-proven simple design.
  
  
• Astralpool (Hurlcon) ICI Series
  
  
• ICI 200, ICI 400 - Pool & Spa Heaters - Super Efficient Combustion & Compact. These are based on the popular Viron heaters, but they removed some components to dramatically simplify the design. Early 2021 had a major design-change, with more safety & diagnostic features added. 
• Astralpool (Hurlcon) Viron eVo Series
  
  
• Viron eVo 250, Viron eVo 350 are a bit simpler than the the eVo 450 and require less waterflow & gas pressure. These have had many revisions over the years, and are nothing like the early MK1 models.  Early 2021 had a major design-change, with more safety & diagnostic features.
  
  
• Viron eVo 450 - Extremely Efficient Combustion & compact. These require large water flow, and perfect gas pressure to operate efficiently. One of the biggest killers of these is 'ignorant' installation. Many plumbers don't know how to tune these heaters and they never run as well as they could
  
  

• Zodiac 

  • JXi 200, JXi 370 are very similar in design to the Mastertemp heaters, but with a major improvement in waterflow. They use a mechanical bypass to ensure water flow is sufficient through the heater at all times. This is very important with variable speed pumps.
    
    
• Pentair / Waterco / Sta-Rite
  
  
• Mastertemp 125, Mastertemp 200, Mastertemp 300, Mastertemp 400

  Super Efficient & Compact. Rotatable top. Must have perfect Gas Pressure, Water Flow, and Water Balance. When manifolds leak on these, due to corrosion, the combustion chamber can fill with water, destroying the heater.

• Astralpool - HINRG - Not Currently Manufactured since 2020
• INSNRG - Not Sold. Not Recommended.
