About this heater

This HydroQuip 4.0KW 230V Low Flow Heater Assembly (27-V000-5T-SPA10) is a universal vertical heater designed for most residential spas and hot tubs requiring low flow heating systems. The 4000-watt element operates on 230-volt power and features HydroQuip's reliable vertical configuration that fits standard heater manifolds across multiple spa brands.

Built to OEM specifications, this heater assembly effectively resolves common heating issues including "HH" high limit errors and "OH" overheat conditions that plague aging spa systems. At Bubbles Supply, we guarantee this is the exact fit for your application and ship same-day from our Canadian warehouse. Plus, every heater comes with our comprehensive 1-year warranty for complete peace of mind. Professional installation recommended – always verify electrical specifications and flow requirements match your spa's system before installation.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • HH high limit fault on spa display
  • OH overheat error code not clearing
  • Spa water not heating or heating slowly
  • Heater element burned out or failed open
  • Spa cycling off prematurely due to heat fault
  • Intermittent heating with nuisance high-limit trips

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your spa runs on 230V — this heater is not compatible with 120V systems
  • Verify your system uses a low flow heater configuration, not a standard flow heater
  • Check that your existing heater manifold accepts a vertical heater assembly
  • Inspect plumbing unions and manifold connections for size compatibility before ordering
  • Diagnose whether the fault is the element, the high-limit sensor, or the control board — replacing the heater won't fix a faulty sensor or board
  • Have a qualified electrician perform installation — 230V heater work is not a DIY job in most jurisdictions

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.

Install difficulty: Hard — Technician recommendedTypically 60-120 minutes
