Hydro-Quip 4.5 kW 240 V Titanium Heating Element for Balboa M7 – 45BNCTTM

TheHydro-Quip 45BNCTTM titanium heating element is designed to replace the element in several compatible spa heaters, including Balboa M7 as well as some older Hydro-Quip and Aquatemp models.

Its butterfly, or BowTie, design BowTie, and its offset terminals facilitate installation in heating tubes where space is limited.

With a power of 4.5 kW at 240 V, this element helps restore fast, stable, and efficient spa water heating.

Durable titanium construction

The outer sheath is made of titanium, a material known for its high resistance to corrosion and chemicals used in spa maintenance.

Titanium benefits

• Excellent corrosion resistance
• Good chemical tolerance
• Superior durability in properly balanced water
• Consistent performance
• Long service life
• Suitable for spas disinfected with chlorine or bromine

Even with a titanium element, it remains essential to maintain pH, alkalinity, and disinfectant levels within recommended ranges.

Compatible with Balboa M7 heaters

This element is mainly designed for heating assemblies Balboa M7 compatible.

It may also fit some older heaters:

• Hydro-Quip
• Aquatemp
• Assemblies using a 4.5 kW BowTie element
• Tubes requiring offset terminals

Compatibility must be confirmed using the part number, dimensions, and configuration of the current element.

BowTie design with offset terminals

The BowTie shape allows integrating an efficient heating length into a compact tube.

Offset terminals, also called offset terminals, are positioned to facilitate electrical connection in some assemblies where space is limited.

Design features

• BowTie or butterfly shape
• Offset electrical terminals
• Length of 9 3/4 in
• Format suitable for compatible heating tubes
• Mounting hardware kit included

Powerful 4.5 kW heating

The rated power of 4,500 watts allows the heating system to maintain water temperature when the element is installed in a compatible heater and water circulation is adequate.

It helps to:

• Replace a faulty element
• Restore spa heating
• Maintain a stable temperature
• Optimize heater efficiency
• Reduce heat-up time

Heating speed varies depending on water volume, spa insulation, outside temperature, and system power.

Pre-purchase checks

Before ordering, compare the following features with those of the currently installed element:

• Part number
• 4.5 kW power
• 240 V voltage
• Length of 9 3/4 in
• BowTie shape
• Position of electrical terminals
• Spacing between terminals
• Heating tube diameter
• Compatibility with the Balboa M7 system

Two visually similar elements may have different power, length, or terminal positioning.

Professional installation recommended

Replacing a heating element requires working on a 240 V electrical circuit and spa plumbing.

Installation should be performed by a qualified technician.

General steps

1. Completely cut off the spa’s electrical power.
2. Confirm absence of voltage.
3. Drain or isolate the heating tube.
4. Remove the old element.
5. Inspect the tube, seals, and connections.
6. Install the new element with the appropriate hardware.
7. Fill the circuit and remove air.
8. Check for leaks.
9. Restore power only when the tube is filled with water.
10. Check voltage, amperage, and heating operation.

Never power the element when it is dry. Operating without water or insufficient circulation can cause rapid failure.

Recommended checks when replacing

A heating element failure may be related to another system issue.

It is recommended to check:

• Circulation pump
• Water flow
• Filter cleanliness
• M7 sensors
• Relays and contactors
• Electrical connections
• Power supply voltage
• Condition of the heating tube
• Water chemical balance
• Presence of scale or corrosion

Fixing the cause of failure helps extend the new element’s lifespan.
