Very common heaters found in older pools. They were robust, but are aging now. Very few parts are available. Surprisingly some can be resurrected.
Common spa heater in the 1980s. There are almost no parts available for these. Keep in mind of their age. Everdure no longer supports these at all & is a different company now.
Not a common spa heater. No spare parts available.
Proved popular for a time, but are no longer supported by Bosch. We do have some aftermarket parts available for these.
Great little heaters. We can actually retrofit many parts on these heaters. Definitely worth looking at.
Older Hayward heaters were very robust. Their new heaters are pretty good.
Older Waterco heaters were often rebranded heaters, but were pretty well built. Again, we carry many spare parts.
Great little spa heaters, generally sold as part of a spa skid pack. We actually repair these heaters fairly often. Many are salvageable and worth the repair.
