  • One Star
The two negative reviews for Raypak are totally accurate. If you are thinking of purchasing a Raypak heater online then first read their huge disclaimer on their own website. THEY DO NOT SUPPORT PRODUCTS PURCHASED ONLINE! Not sure what the difference is. I replaced a 30+ year old Raypak millivolt pool heater in 2010 with the exact same model. I figured why mess with success right? Well 50 months later this thing is leaking like a sieve where the tubing bundle is coming apart. Sure it can be replaced... for $600 and that is just the part! Tried to contact Raypak but they don't respond and they do not list their telephone number. Considering I spent almost $1600 for this junk heater the average cost to own one of these is just over $1 per day! Not a good value by any stretch of the imagination. My recommendation is to stay far away from these products... very far away! ... show more

  • After nearly 20yrs service from old Raypak, replaced with new, and love it!
After reading the other review that was so negative I had to write my own so that everyone has another view of this great heater. First of all, in regard to the very negative review concerning service, I do not have an opinion on how good or bad Raypak service is because I've never had to call them! It does say in the manual that you have to keep your water levels balanced or damage may occur. I would like to imagine your water levels would have to be VERY bad to actually affect this unit, such as very high acidity/low ph. If it leaks, then likely a header gasket is bad or main/return connections are bad, OR, a faulty install all together and it overheated resulting in a cracked heat exchanger, OR bad freeze protection circuit (which is not the responsibility of Raypak, it is a unit that kicks on the water pump for those that don't know) and the heatexchanger cracked from being frozen with water in it. Just my two cents. As far as I'm concerned Raypak makes a really great pool heater. I just replaced a nearly 20yr old Raypak with a new Raypak 406k and absolutely love it! It is still one of the easiest to hook into a compool or aqualink control system, digital interface with precise target temp control (unlike a millivolt unit that is hard to dial in your temp with any accuracy). My father replaced his Raypak about a year before I did and his was about 17yrs old. His unit stays in direct sunlight while mine is always under shade, not sure if that is why I got extra years or not. I talked my brother in-law into replacing his 4yr old extremely troublesome and expensive Teledyne Laars with a Raypak, going on 8yrs now and not a single problem. I would give this product 10 stars if I could to offset the very unfair 1 star that the other guy left over a service dispute that was likely his fault to begine with, or perhaps a bad apple, either way Raypak is worth more than 1 star in my opinion. ... show more

  • WASTE OF MONEY
This is an expensive product and Raypak does not stand behind the warranty! We purchased this and had it installed. Within 4 to 5 months, it was leaking. I contacted the manufacturer to begin a warranty claim. BE WARNED - they will blame failure of their product on YOU. They will blame your water chemistry and they will void your warranty! As any pool owner knows, water chemistry will fluctuate over days, weeks, etc. I tested my water 2 to 3 times a week and followed up at a pool store every other week. I take care of my pool. Raypak will blame you for their poorly designed heater's failure. I STRONGLY ADVISE YOU DON'T MAKE THE MISTAKE WE DID - DON'T BUY THIS PRODUCT OR ANY LIKE IT. ... show more
