135L Gas Storage Hot Water Systems
Explore 135L gas storage hot water systems for lower-to-moderate household demand and compact replacement applications. Compare burner recovery, Natural Gas or LPG configuration, dimensions, gas input and installation fit before choosing a 135-litre gas storage water heater.
What Is a 135L Gas Storage Hot Water System?
A 135L gas storage hot water system is a tank-style gas water heater with a nominal storage capacity of around 135 litres. It keeps hot water stored and ready for use, then reheats the tank with a gas burner as the temperature falls or hot water is drawn off.
Compared with electric storage, gas storage performance depends heavily on burner recovery. A 135L gas tank can therefore suit applications where compact storage is preferred but faster reheating is available.
Is a 135L Gas Storage Hot Water System Big Enough?
Lower-to-Moderate Demand
135L can suit homes where daily hot-water use is moderate and heavy simultaneous demand is limited.
Compact Replacement Sites
This capacity can suit properties replacing an existing smaller gas storage tank where space is limited.
Fast Recovery Matters
Gas burner recovery can restore usable hot water quickly after showers or other significant draws from the tank.
Like-for-Like Replacement
If an existing 135L system has comfortably met demand, another similar-capacity gas storage unit can be a straightforward path.
135L Tank Size vs Burner Recovery
Tank capacity determines the stored reserve, while burner recovery determines how quickly the water heater can replace hot water after use. Both need to be considered when sizing a 135L gas storage system.
A household with short periods of concentrated demand can benefit from faster recovery even where the tank itself is smaller than a larger electric storage system.
Gas storage typically relies much more heavily on recovery during use. The useful comparison is stored capacity plus recovery, not tank size by itself.
Should I Choose a 135L or 170L Gas Storage System?
Choose 135L where demand is lower to moderate, the existing system has performed well and a compact tank is desirable. Choose 170L where the household needs more stored reserve before relying on burner recovery.
The larger tank can provide more buffer for back-to-back showers or heavier evening demand, while 135L can be more practical where space and replacement fit are important.
Are 135L Gas Storage Systems Available in Natural Gas and LPG?
Availability depends on the product range. Gas storage systems can be offered in Natural Gas or LPG versions, and the selected model must match the property’s actual fuel supply.
Do not assume the Natural Gas and LPG versions are interchangeable simply because they share the same 135L capacity or external dimensions.
Does a 135L Gas Storage System Need a Particular Gas Line?
The gas supply must be capable of supporting the burner input of the new water heater as well as other gas appliances connected to the property.
Pipe size, run length, regulator or meter capacity and total gas load can all affect whether an existing line is suitable for the replacement system.
Does Star Rating Matter on a 135L Gas Storage System?
Yes. The gas star rating helps compare efficiency between suitable gas storage models. It indicates how effectively the appliance uses gas under the applicable rating method.
Efficiency should be considered after confirming that the tank capacity, burner recovery, fuel type and installation arrangement suit the property.
Does a 135L Gas Storage System Need a Flue?
Gas storage systems need to manage combustion products safely. The exact flue or ventilation arrangement depends on the appliance design and whether it is intended for indoor or outdoor installation.
When replacing an existing 135L system, compare the new model’s installation requirements rather than assuming every tank uses the same combustion arrangement.
Are All 135L Gas Storage Systems the Same Size?
No. Similar-capacity tanks can vary in height, diameter or width, base footprint, gas connection, water connection positions and required clearances.
Measure the existing installation area and compare the exact model dimensions before ordering a replacement.
What to Compare Between 135L Gas Storage Systems
| Feature | Why it matters | What to check |
|---|---|---|
| Tank capacity | Determines stored hot-water reserve. | Whether 135L suits actual household demand. |
| Recovery rate | Determines how quickly hot water is restored after use. | Compare manufacturer recovery information and burner input. |
| Fuel type | Natural Gas and LPG versions are different. | Match the appliance to the property’s actual gas supply. |
| Gas efficiency | Affects gas use for a suitable system. | Compare star rating between like-for-like models. |
| Dimensions | 135L models can vary physically. | Height, diameter/width, base footprint and clearances. |
| Connections & flue | Affects replacement complexity. | Gas, hot/cold water, relief valve and combustion arrangement. |
Do I Need New Valves with a Replacement 135L Gas Tank?
The replacement system needs valvework and pressure control suited to the exact cylinder and installation. Existing valves should not automatically be assumed suitable simply because another gas storage tank is already installed.
Compare the new product’s pressure requirements and relief-valve specification as part of the replacement assessment.
Replacing an Existing 135L Gas Storage Hot Water System
Before ordering, photograph the old data plate and record the brand, model, tank capacity, Natural Gas or LPG configuration, burner input, dimensions, pressure information, gas connection, hot and cold water positions and flue or outdoor arrangement.
Also consider whether the old 135L system actually met demand. If it regularly ran out, compare a 170L system or stronger recovery rather than automatically replacing litre-for-litre.
When Should I Move Up from 135L Gas Storage?
Consider moving to a larger gas storage tank where the household regularly depletes the 135L reserve during normal use, particularly with repeated showers, regular baths or heavier evening demand.
Before upsizing, confirm the existing system is recovering correctly. A burner or control fault can make a correctly sized tank appear too small.
