Hot Water Systems in Loganholme
Ask whether the old unit can be repaired first, then let your household’s morning peak and your own block decide what goes in.

Morning peak, precinct and low ground in Loganholme
Jim Monger Plumbing and Gas repairs, replaces and installs gas, electric and heat pump hot water systems. Loganholme is in our service area, and our base is at Victoria Point. Homeowners, landlords and property managers here are usually deciding for a stand-alone house, since 92.7% of occupied dwellings were separate houses at the 2021 Census, which makes the outdoor position a real question. And 29.3% were rented, so the person approving the job may not be the person without a shower. Either way, the first thing to settle is repair or replacement. Have the unit type and what it is doing ready when you ring.
Start with whether the old unit can be fixed at all. If it cannot, how many people need hot water at once comes next. Position follows, but only part of the suburb sits in the Loganholme local plan, whose precincts hint at the kind of home and set no hot water rules. The mapped fall to lower ground applies within that area only.
We repair as well as replace, so settle that first; if replacing, count bedrooms, because 46.7% of Loganholme homes had four or more at the 2021 Census against 38.8% across Queensland. With only 4.9% at two bedrooms against 17.0% statewide, a small like-for-like unit may not suit. Families made up 79.5% of households in 2021, against 71.0% statewide, which is likely to bunch showers into the same mornings and evenings. Count showers and laundry loads in your busiest half hour before choosing a tank or continuous flow: Rinnai says flow from its gas continuous flow units may be limited when several taps or showers run together.
Position starts with the Loganholme local plan, which covers only the residential area between Bryants Road and Beenleigh-Redland Bay Road, and whose seven precincts set planning outcomes, not hot water rules. Plans range from dwelling houses in the Large lot residential precinct to medium intensity multi-storey housing in the Residential core beside Shailer Park, so a precinct is only a clue to the kind of home and site. An attached home in the Residential core is likely to have less outdoor room than a Large lot house, so raise a heat pump’s position early, because Rinnai says its heat pumps need adequate airflow and space and typically sit around 45-46 decibels. Outside the plan area, say whether it is a home or business premises, because Wikipedia puts a large commercial and industrial area east of the Pacific Motorway.
Within the plan area, the precinct map shows land falling from about 20 metres to about 5 metres in the Bryants Road local centre and on the Large lot precinct’s south-western edge, and slope can affect where a unit and its drain can go. The scheme also maps a Torres Street catchment for on-site flood detention in new development, which does not cover a water heater swap. Wikipedia has the Logan River along the suburb’s southern and western boundaries. None of the three shows that a given block floods, but if yours is near one, read its Flood Report on the Logan Flood Portal before siting a ground-mounted unit, and discuss unit height and placement at quote stage if it raises a concern. At any home, if floodwater reaches a gas or electric unit, Logan City Council says not to use it until a service provider has checked it, so that check comes before any repair or replacement decision.
Hot water problems to rule out before replacing
Hot water gone by the second shower
An undersized system and a failing part both tend to show up when showers bunch together, so the two can look alike from the bathroom. A bigger unit may not fix a fault, and a repair may not help a system that was always too small for the house, so it is worth separating the two. Tell us when the household uses hot water and when it runs out, because the answer helps with both the diagnosis and the choice of system.
Replacement assumed before asking about repair
When the hot water stops, a new unit can seem the obvious answer, although repairs are also an option and may sometimes be enough. One Google reviewer says a call to us saved them from buying a new hot water system they did not need. Ask whether a repair is possible before agreeing to a new unit. We do both repairs and replacements, and that Google reviewer says they were told honestly what they really needed to do.
Scale blamed without a check
Logan Water’s 2024/25 report lists Loganholme mainly in the Kimberley Park zone, where 48 hardness tests averaged 138.61 mg/L, about twice the 69.59 mg/L of Logan East, the zone that lists Beenleigh. That average still sits inside the 60-200 mg/L band Logan City Council classes as 'Good’, so scale is possible but not a safe assumption, and a street can move between zones. Ask what the actual fault is before agreeing to water treatment or a new unit, because zone figures say nothing about your own tank.
Rusty or discoloured hot water
Logan City Council says orange or rusty brown water that clears after 2 to 5 minutes may indicate corrosion in the house plumbing, and discoloured water can also follow nearby mains maintenance. Neither cause automatically means a failed tank, so a new unit may not solve it. Note whether it clears after 2 to 5 minutes and tell us when you ring, so the starting point can be checked before anyone talks about replacing the unit.

Frequently asked questions
Can’t see your question? Call us and we’ll talk it through.
Call 0418 871 269What should I tell you when sizing a hot water system for a Loganholme home?
Your head count and how many showers and taps run at once at your busiest time. Loganholme averaged 2.9 people per household at the 2021 Census, above the 2.5 average for Queensland, but a suburb average is not a sizing rule, so your own numbers matter more.
Does a heat pump suit a townhouse or apartment in Loganholme?
It depends on where the unit would go. Rinnai says its heat pumps require adequate airflow and space, make some noise while heating water and can lose efficiency in colder weather, so the deciding factors are how much open space the unit would have and how close it would sit to bedrooms and neighbours. In a complex, also ask whether the body corporate has a say in where an outdoor unit goes, which is a general question and not a planning rule.
Could the flood map for my Loganholme block change?
Logan City Council has endorsed limiting its flood hazard overlay mapping to the 1% annual chance event, with changes expected in early 2027 subject to Queensland Government approval. Check the current map or report close to when you decide where a unit goes.
Does replacing a hot water system need a licensed plumber?
Yes. QBCC lists installing, replacing or removing a water heater in an existing building as notifiable plumbing work, and that category must be performed by a QBCC licensed plumber or drainer. You can ask your plumber to confirm the work has been notified.
I manage a rental in Loganholme. How do we handle a failed system?
Tell us who signs off the work and how to reach the occupant, so clear repair or replacement information goes to the person deciding. Our plumbing maintenance covers rental properties as well as homes.
Can someone come out tonight if the hot water has failed?
Emergency calls are taken 24/7, including weekends. Arrival depends on the job and the time of the call, so ask when you ring.
