Cadac 16L Low Pressure Gas Water Heater – Compact, Load-Shedding Proof

The Cadac 99400-01-16-LP is a 16-litre gas water heater built for smaller households, delivering hot water through load shedding on battery pulse ignition with zero mains electricity required. At 10.4kg and a slim 740mm x 400mm x 210mm footprint, it’s the more compact option in Cadac’s low-pressure range, and it starts from the same low 0.03MPa water pressure as the bigger 20L model, so gravity-fed farm and off-grid systems still work.

If you’re kitting out a smaller home, a flat, or a single-bathroom property, this is sized to match — 5 to 16 litres of hot water a minute is comfortably enough to run a shower, kitchen tap, and washbasin at the same time without needing the extra capacity (or the extra gas) of the bigger model. Like its 20L sibling, it ignites on two D-cell batteries rather than mains power, so hot water keeps flowing through stage 6 load shedding exactly as it would on a normal day. Independent gas and water flow dials let you tune the output temperature as winter water gets colder.

The 32kW burner is sized to the smaller flow rate, which also means it uses less gas — rated at up to 2.52kg/hour versus 2.9kg/hour on the 20L unit, so running costs are lower if you don’t actually need the bigger model’s output. It carries the same safety package as the rest of the range: automatic flame-out protection, an anti-freeze sensor, and a dry-combustion cutout, so you’re not trading safety features away for the smaller size.

It suits two-bedroom homes, flats, cottages, and smallholdings that don’t need multi-bathroom capacity, plus anywhere wall space is tight — the slimmer 400mm width makes it easier to mount on an external wall than the larger model. You’ll still need a 9kg LPG cylinder or larger and correct ventilation, so get a qualified gas installer to handle the connection.

Key Specifications

• Low-pressure start-up (from 0.03MPa) — fires on gravity-fed tanks and weak-pressure systems most gas geysers can’t handle
• Battery pulse ignition (2x D-cell) — 100% independent of mains electricity, runs straight through load shedding
• 32kW thermal output, 5-16L/min — sized for a shower, kitchen tap and basin running together
• Lower gas consumption than the 20L model (up to 2.52kg/hour) — cheaper to run if you don’t need the bigger flow rate
• Dual gas/water control knobs — adjust temperature independently as seasons change
• Automatic flame-out, anti-freeze and dry-combustion protection — same safety package as the larger model
• Compact 10.4kg, 740 x 400 x 210mm — easier to mount where wall space is tight
• Requires a 9kg LPG cylinder or larger — budget for bottle size when installing
• 12-month manufacturer warranty — backed by Cadac

Frequently Asked Questions

Is the 16L model big enough for a family home, or should I get the 20L?

The 16L delivers 5 to 16 litres a minute, which comfortably covers a shower, kitchen tap and basin running at the same time — plenty for a smaller household or a single-bathroom property. If you regularly need two bathrooms running hot water simultaneously, or you’ve got a larger family working through multiple showers back-to-back, the 20L model’s higher 6-20L/min range gives you more headroom.

How much LPG gas does a gas water heater like this use?

This model uses up to 2.52kg of gas per hour at full output, so a standard 9kg cylinder gives you a few hours of continuous hot water use before it needs replacing. In normal daily use — showers, dishes, basin — that typically stretches to a few weeks per cylinder for an average household, though actual usage varies with household size and how many showers run back to back.

Does Daily Discounts deliver gas water heaters, and do you handle installation?

Delivery is nationwide and usually takes 3 to 5 working days. Installation isn’t included — this is a gas appliance and needs a qualified gas installer to connect and ventilate it correctly, both for safety and to keep the manufacturer’s warranty valid.
