Choosing the Right Instant Gas Hot Water System
Before ordering an instant gas hot water system, check the existing unit and compare the product specifications carefully. Instant gas hot water systems can vary by fuel type, flow rate, temperature setting, dimensions, water pressure requirements, connection layout and power requirements.
Check these details before buying:
Gas type, either natural gas or LPG
Brand and model number of the existing system
Flow rate in L/min
Water pressure rating in kPa
Hot and cold water connection locations
Gas connection size and location
Inlet and outlet connection sizes
External, outdoor or approved location suitability
Power requirements where relevant
Temperature setting
Minimum flow and pressure requirements
Required valves and fittings
Available space for the unit
Household hot water demand
Delivery access
Spare part compatibility
Natural gas and LPG instant gas hot water systems are not the same. Always choose the correct gas type before ordering.
Instant Gas Hot Water Flow Rates Explained
Instant gas hot water systems are usually compared by flow rate in L/min rather than tank capacity. This is because they do not store hot water in a tank. Instead, they heat water as it flows through the unit.
Common flow rate considerations include:
Number of people in the home
Number of bathrooms
How many hot water outlets may run at once
Shower usage
Kitchen and laundry demand
Incoming water temperature
Required temperature rise
Natural gas or LPG availability
Product specifications
A smaller flow rate may suit compact homes, units or lower demand properties. A higher flow rate may suit larger households, multiple bathrooms or homes where more hot water outlets may be used at the same time.
Natural Gas and LPG Instant Hot Water Systems
Instant gas hot water systems must be matched to the correct gas type.
Natural gas instant hot water systems are designed for properties connected to mains natural gas. LPG instant hot water systems are designed for bottled gas supply. These products are not interchangeable unless a specific model is designed or approved for conversion using the correct parts and requirements.
Before ordering, check the label on your existing unit or product specifications to confirm whether natural gas or LPG is required.
Instant Gas Hot Water Compared With Gas Storage
Instant gas hot water systems and gas storage hot water systems both use gas, but they work differently.
An instant gas hot water system heats water as it passes through the unit. It does not store hot water in a tank and is usually compared by flow rate in L/min.
A gas storage hot water system heats and stores water in a tank ready for use. It is usually compared by storage capacity in litres.
The right choice depends on your existing system type, gas supply, household hot water demand, available space, water pressure, budget and product specifications.
Instant Gas Hot Water Parts, Valves and Accessories
An instant gas hot water order may require more than the main unit. Valves, pipework, fittings and accessories can be needed to suit the water pressure, temperature control requirements and connection layout.
Common products used with instant gas hot water systems include:
Tempering valves
Pressure limiting valves
Expansion control valves
Isolation valves
Non-return valves
Duo valves
Hot water connection kits
Copper connections
Braided connections where suitable
Unions and adaptors
Drain cocks
Gas hot water spare parts
Maintenance accessories
Ordering compatible hot water parts with the system can help make sure the right products are ready when needed.
