Onga Ultra 2700 3300 4700 Spa Gas Heaters OBSOLETE - NLA

This product is obsolete or unavailable.

Scroll down for replacement options.

Description

The Onga Ultra 2700, 3300, and 4700 gas spa heaters were a Japanese heater branded by Onga, often fitted to a Spa Skid Pack. The control systems were poorly made, and no spare parts are available.

They were built in the 1990s & early 2000s, before being completely abandoned by Onga & Pentair several years ago.

All parts Obsolete and No Longer Available (NLA).

The best replacement is either the HX70 or HX120 for ground-mounting. If you can only replace with a wall-mounted heater, the JX130 or JX160 is the best option.
