Hot Water Systems

Reliable hot water is one of those things you only notice when it's gone. Laser Plumbing Hamilton West installs, services, and repairs all types of hot water systems — electric, gas, and heat pump — so you get the right setup for your home and budget, backed by local expertise you can call on any time.

Low Pressure Cylinders

A traditional electric storage cylinder where water pressure is restricted (typically 7–12L/min). If your home is pre-1990s, you’re probably on low pressure or wetback (heated by fire).

PROS:

Cost-effective upfront
Simple technology, long-lasting
Good for smaller households or budget builds
Able to be used with a wetback system.

CONS:

Lower water pressure (affects showers + multiple outlets running at once)
Less common in new builds
Requires specific tapware compatible with low pressure

Electric Mains Pressure

Gas Mains Pressure Cylinder

Provides consistent pressure with faster heat recovery than electric cylinders.

PROS:

High pressure
Faster recovery than electric
Works with all modern tapware
Great for larger households
Natural gas option offers lower running costs

CONS:

Larger footprint than continuous flow
Requires correct ventilation and gas compliance
Running costs vary depending on LPG vs natural gas
Storage-based system (limited to cylinder volume)

Continuous Flow Gas Water Heater

Provides consistent pressure with faster heat recovery than electric cylinders.

PROS:

High pressure
Faster recovery than electric
Works with all modern tapware
Great for larger households
Natural gas option offers lower running costs

CONS:

Larger footprint than continuous flow
Requires correct ventilation and gas compliance
Running costs vary depending on LPG vs natural gas
Storage-based system (limited to cylinder volume)

Electric Instantaneous Hot Water Systems

Small electric-powered units that heat water on demand as it flows through the system, similar to gas continuous flow, but powered only by electricity.

PROS

Compact, wall-mounted, no cylinder required
Provides hot water only when needed (no storage losses)
Good for small spaces, tiny homes, offices, sleepouts
Simple installation when electrical capacity is adequate
No need for gas supply or bottle storage

CONS

Requires high electrical load (often 40–63A circuits)
Usually not suitable as the main hot water source for full homes
Lower flow rates — may struggle with multiple taps/showers at once
May require switchboard upgrades in some homes
Better suited as point-of-use units (e.g., kitchen, external cabin)

Hot Water Heat Pump System

A highly efficient system that uses ambient air to heat water — similar tech to a heat pump for heating/cooling.

PROS:

Up to 3–4x more efficient than standard electric cylinders
Significant ongoing power savings
Great for energy-conscious builds
Ideal for homeowners wanting lower monthly bills

CONS

Higher upfront cost
Outdoor unit requires space and airflow
Slight operating noise
Best performance in moderate climates

 Thanks Laser and the team. Prompt and efficient service as is usual. We had guests and the toilet started constantly flowing. The plumber (Brian) turned up replaced a washer and realigned things and now its good as gold.

 Water was pouring through the light socket from in the ceiling. Rang Laser and they said well send someone right away. That they did and repaired it promptly. Great service with really nice staff.

 I liked the professionalism and knowledge Brian was great at explaining what he was doing even though he probably done this job a million times made me feel at ease top guy . Well worth the price in the invoice. Thanks very much.
fred pilling
 10 stars for Brian. He always answers our calls and comes up with a solution. AND I especially appreciate he never laughs at my silly suggestions (I'm sure he does on the inside) but just suggests a remedy. He really is an asset to your company!
Janeen Foote
 Wonderful company to deal with. Friendly, helpful staff. No question or query from me was too hard. Advised I needed my septic tank cleaned out, when asked who I should contact offered to organise for me. Had someone here the following week. Highly recommend them
Judith Blincoe-Eddy
 Brian swiftly resolved our shower drain issue in 20 minutes, a task that had stumped two other plumbers from a different company. He quickly diagnosed the problem and implemented a fix with remarkable efficiency. Will not hesitate to use Laser Plumbing Hamilton West for all our future plumbing needs.

 Excellent service. Another plumber came up with the solution of total unit replacement and Laser was able to replace a part for a fraction of the price, maintaining the aesthetic of the room.
