Swimming Pool Store for Shelly Beach

Sunshine Coast Region, QLD

The cheapest heater to buy is rarely the cheapest to own

Solar, heat pump and gas compared on your pool, not on a brochure

Shelly Beach is the smallest and most settled of the suburbs this shop covers — 925 residents at the 2021 Census, a median age of 48, and 45.3% of occupied dwellings owned outright, the highest outright-ownership share of the six. 81.7% are separate houses. Settled owners in long-held homes tend to want their pool to be usable rather than ornamental, and that is where most Shelly Beach conversations at our counter end up: heating, and whether it is worth it.

It is worth having the conversation properly, because the three options behave very differently and the cheapest to buy is rarely the cheapest to own. A heater chosen on purchase price alone is the most common expensive mistake in this part of the shop.

The first question we ask is not which system you want. It is how you actually use the pool — because a pool used occasionally and a pool used most mornings want different answers, and the honest recommendation changes completely between them.

Local knowledge

Why it matters here

**Solar** has the lowest running cost by a wide margin, since it is essentially free once installed. It needs adequate roof area with a decent northerly or easterly aspect, and it heats when the sun is out — which means it extends your season rather than guaranteeing a temperature on a given day.

**A heat pump** is the choice for genuine year-round swimming. It draws warmth from the air and delivers more heat energy than the electricity it consumes, holds a set temperature reliably, and works overnight and in cloud. Higher purchase price, modest running cost, and much better paired with a blanket.

**Gas** heats fast, on demand. It suits a pool that needs to be warm on short notice rather than kept warm continuously — a holiday house or a spa — because running it around the clock gets expensive quickly.

A common answer here is solar plus a blanket for a long shoulder season, with a heat pump added only if the household really does swim through winter. But that is a starting point, not a recommendation: we ask how you use the pool before suggesting anything.

What owners come in for

Common local challenges

The challenge

Choosing a heater on purchase price

Why it happens

Purchase price is the visible number. Running cost arrives quarterly and is easy to discount at the point of sale.

Why it matters

The cheapest unit to buy is frequently the most expensive to own, and the decision is hard to undo once it is plumbed in.

How we help

We give an estimated seasonal running cost alongside the purchase price, so the two can be compared properly rather than one at a time.

The challenge

Heating an uncovered pool

Why it happens

The heater feels like the product and the cover feels like an accessory.

Why it matters

Most heat loss is evaporative and overnight, so an uncovered heated pool spends much of its energy on the atmosphere.

How we help

We quote the blanket as part of the system rather than an upsell, and would rather specify a smaller heater with a cover than a larger one without.

The challenge

Sizing by rule of thumb

Why it happens

Heater capacity is easy to guess from pool volume alone.

Why it matters

Volume is not the driver — surface area, wind exposure, shade and the temperature you want to hold are. A unit sized on the wrong variable either never reaches temperature or costs more than it needed to.

How we help

We quote on site against surface area, exposure and target temperature, not from a table.

The challenge

Solar on a roof that cannot carry it

Why it happens

Solar is the obvious first choice on running cost, so it gets specified before anyone looks at the roof.

Why it matters

A south-facing or shaded array underperforms permanently, and the owner concludes solar does not work rather than that this roof does not.

How we help

We assess the roof before quoting and will tell you if a heat pump is the better fit for your house.

The challenge

Setting the temperature higher than necessary

Why it happens

A thermostat invites a round number.

Why it matters

Every degree above your actual comfort point costs meaningfully more to hold, all season.

How we help

We will suggest finding your real minimum rather than defaulting high, and set it with you rather than leaving it on a factory value.

What is on the shelves

Pool heating — solar

Roof-mounted solar heating, assessed on your roof's aspect and available area before quoting.

Lowest running cost of the three, and best understood as extending the season rather than holding a temperature.

Ask about solar

Pool heating — heat pumps

Air-source heat pumps that hold a set temperature through cloud and overnight.

The option for a household that genuinely swims through winter. Much better paired with a blanket.

Ask about heat pumps

Pool covers and blankets

Measured and ordered to your pool's shape, with roller options.

Most heat loss is evaporative and overnight. We would rather specify a smaller heater with a cover than a bigger one without.

Heating servicing

Annual checks that keep a heat pump running at the efficiency it was bought for.

Efficiency drifts quietly. The bill is usually the first thing that tells you.

Book a service

Free water testing

A full profile with a printed dosing plan, at the same counter.

A heated pool still needs the basics right — warmer water changes sanitiser demand.

Bring a sample in

Pumps, filters and parts

Pumps, filters, chlorinators and spares, plus the plumbing work that goes with a heating retrofit.

Heating is added to the plant, so the plant is worth checking at the same time.

Credentials and cover

Billabong Pool Service & Supply publishes ABN 63 010 047 239 and QBCC Licence No. 69021 in its own site footer. The shop is at 134 Bulcock Street, Caloundra QLD 4551 on 07 5438 1588, trading Monday to Friday 8:00am–4:30pm and Saturday 8:00am–12:00pm. The team quotes on site, installs, and services what it sells — including the annual checks that keep a heat pump running at the efficiency it was bought for. The same counter carries the water testing, chemicals, cleaners and parts side, because a heated pool still needs the basics right. Billabong does **not** issue pool safety certificates and does not perform pool safety inspections — that is a licensed pool safety inspector's work.

Frequently asked questions

What will it cost me to run?

It depends on your pool's surface area, the temperature you want to hold and whether it is covered — which is why we quote on the actual pool rather than publishing a number. You get an estimated seasonal running cost alongside the purchase price so you can compare the options properly.

Can I heat the pool with solar if my roof faces the wrong way?

East-facing generally works. South-facing rarely does well enough to justify it. We assess the roof before quoting and will tell you if a heat pump is the better fit rather than selling you an array that will disappoint.

How warm should I set it?

Warm enough that you actually use it, and no warmer. Every degree above your real comfort point costs meaningfully more to hold across a season, so it is worth finding your minimum rather than setting a round number by default.

Can heating be added to an existing pool?

Almost always, yes. It is a common retrofit and does not require reworking the pool itself, just the plant.

Do I really need a blanket as well?

If you are heating, yes — it is closer to half the system than an accessory. Most heat loss happens at the surface overnight through evaporation, so an uncovered heated pool spends a lot of its energy on the air above it.

Which of the three should I pick?

It depends far more on how you use the pool than on the pool itself. Occasional use at short notice points one way; a daily swim through winter points another. That is the first thing we will ask.

Next step

Want to keep swimming past Easter? Let us work out what that actually costs on your pool — surface area, exposure and the temperature you want to hold, with the running cost next to the purchase price. Call 07 5438 1588 or come in to Bulcock Street.
