These are replacements for all the previous versions of the "No-Fault" heaters installed in Hot Spring Spas and Tiger River Spas. Hot Spring is now recommending that the 4 Kilowatt version be used as a replacement for the 6 Kilowatt version as well to help prevent spurious high limit tripping. Some plumbing modification may be needed, but this heater is threaded to accept the two sensors and comes with a high limit reset.Some of the part numbers this heater replaces are:
