About this heater & sensor part

Heater Union Split Nut Assembly - 2". Heater elements, heater assemblies, pressure and flow switches and temperature/hi-limit sensors are the most common no-heat repairs.

Heater elements, heater assemblies, pressure and flow switches and temperature/hi-limit sensors are the most common no-heat repairs. Check your control system brand (Balboa, Gecko, Hydro-Quip and others), the heater length and kW, and the connector type against your old part. A clean filter and good water flow come first: many heater errors are flow problems.
