Storage or continuous flow — which gas system?

Gas hot water is not one product. The two main families behave differently in real Adelaide homes.

Gas storage heats a tank of water and holds it ready. It suits households that like simple, robust plant and can accommodate tank space outdoors or in a cupboard. Recovery rate and tank size determine how many showers you get before the water cools.

Continuous flow (instantaneous) heats water on demand as it passes through the unit. There is no large storage tank. Performance depends on gas supply, unit capacity (litres per minute) and how many outlets run at once. They shine where space is tight and simultaneous use is moderate to well-matched to the unit size.

We help you choose based on bedrooms, bathrooms, morning rush habits and existing gas capacity — not a one-size flyer.

Sizing the unit to your household

Undersized continuous-flow units feel lukewarm when two showers and the kitchen run together. Oversized storage wastes purchase cost and standing energy. We ask practical questions:

• How many people live here, and when is the peak shower window?
• One bathroom or three?
• Dishwasher and washing machine on hot?
• Is the gas meter / pipework adequate for a larger continuous-flow burner?
• Where can the unit hang or stand with correct clearances and flueing?

Homes in Paradise and Magill often move from ageing storage to continuous flow during kitchen or bathroom upgrades — we check the gas run before promising a high-output wall unit.

Connect gas and water to code

Installation is more than hanging a box. We:

• Position the unit with manufacturer clearances
• Connect cold inlet, hot outlet and any condensate / relief drainage required
• Complete licensed gas fitting to the appliance — sizing, isolation, testing
• Fit or verify tempering valve installation so outlet temperatures at taps stay safe
• Commission burners / ignition and confirm stable hot water at fixtures

Natural gas and LPG setups differ. Tell us which you have when booking so regulators and appliance variants match.

Removing and disposing of the old unit

Old storage tanks are heavy, sometimes still partly full, and often leave a mess of obsolete valves. We isolate, drain as required, disconnect gas and water, remove the unit, and leave the area tidy. Continuous-flow changeovers usually free wall space and let us rationalise tangled flexible connectors from past DIY attempts.

Tempering, scalding risk and lukewarm complaints

New hot water systems need safe delivery temperatures at sanitary fixtures. Tempering valves mix in cold water to bring tap temperatures down to code requirements. If your “new” system feels lukewarm everywhere, or one tap scalds while another is tepid, the tempering set-up or a failing valve may be involved — we set and test as part of proper gas hot water installation, and we repair/replace tempering valves when they are the culprit.

Compliance certificates

Gas hot water installation includes testing and a gas compliance certificate for the gas work we complete. Keep it with your property records and insurance file. Rentals and strata managers often need a copy — ask when we finish and we will make sure you have what you need.

When gas hot water is the smart choice

• You already have adequate natural gas or a practical LPG arrangement
• You want strong recovery or well-sized continuous flow for busy mornings
• Electric switchboard or tariff constraints make large electric storage awkward
• You are replacing a failed gas unit and want like-for-like simplicity

If solar, heat pump or electric storage might suit better, we will say so and point you to general hot water system installation options rather than forcing gas.

Repairs vs replace — deciding at the quote

Sometimes you call for install because the old unit is finished; sometimes you hoped for a repair. If the tank is leaking through the shell, or a continuous-flow heat exchanger is beyond economical repair, replacement is the honest path. For component faults, see hot water repairs and hot water system leaking — we will not sell a new gas system when a valve would do.

What we need for an accurate quote

• Photos of the existing unit, flue and gas meter / bottles
• Household size and number of bathrooms
• Preference for storage vs continuous flow (if you have one)
• Access notes — side path width, unit upstairs, locked gates
• Whether tempering valves are already fitted

Flueing, clearances and outdoor placement

Gas hot water units need correct clearances from windows, doors, meters and combustible surfaces. Continuous-flow flues and fan outlets must discharge where exhaust will not re-enter living spaces. We will not install in a location that fails manufacturer rules just because the old rusty tank sat there for twenty years.

Side paths in eastern foothills homes can be tight. Measure before you buy a unit online. Bring us in for a site look if clearances are questionable — a thirty-minute visit beats a refused install on delivery day.

Upgrading from electric to gas (and the reverse)

Switching fuels is a project, not a swap. Electric-to-gas needs a compliant gas run and sometimes meter capacity checks. Gas-to-electric or heat pump needs switchboard and circuit capacity. We map the real works so your quote reflects trenches, wall chasing or electrical coordination — not a fantasy “drop-in” price.

Aftercare for new gas hot water

• Keep the certificate with your home file
• Do not store paint or solvents against the unit
• Clear leaf litter from around outdoor continuous-flow intakes
• Note isolation valve locations for everyone in the house
• Call promptly if you smell gas after install — rare, but treat seriously

Based at Russell Rd, Athelstone, we schedule gas hot water changeovers across East, North-East and West Adelaide within Monday–Friday 7:30am–5:00pm. Call 0401 916 325 when your old unit starts showing age — rust at the base, longer recovery, or rising repair frequency — so you choose the replacement window rather than an emergency Saturday without hot water.

Busy households and morning peak performance

Families with overlapping showers need either adequate storage recovery or a continuous-flow unit rated for the simultaneous litres-per-minute they actually use — not the brochure’s best-case single shower figure. We talk through real mornings: who showers when, whether the kitchen runs hot at the same time, and whether a bathroom renovation added a second shower rose. That conversation prevents the “new system still goes cold” complaint that is really a sizing miss.

If you are unsure, we would rather install correctly once than upsell a second upgrade six months later.

How to book installation

1. Call or email with photos and household details.
2. We recommend storage or continuous flow and quote supply + install.
3. On the day we remove the old unit, install, connect, temper, test and certify within business hours.
