Fischer FWH-8L INSTANT GAS WATER HEATER Copper Wire

Fischer FWH-8L is an 8-litre‐per‐minute rated instant (tankless) gas water heater, designed to supply hot water on demand without a storage tank, making it well suited for a bathroom or washroom in a Pakistani household. Key features include:

• A copper heat-exchanger / burner assembly: listings highlight a “99.9% pure copper heat exchanger” for the FWH-8L model. 

• Instant heating: Water is heated as it flows, rather than stored, which reduces standby heat loss and can yield hot water nearly immediately when the tap is turned on (subject to flow and gas conditions) 

• Comprehensive safety features: flame failure protection, over-heat protection, dry‐burn / low-pressure protection, anti‐freezing (in some listings) and automatic ignition. For example, one listing mentions “Auto Cut Off Protection Device – Anti-freezing & Dry Protection Device – Water Controlled Automatic Ignition – Zero Operating Water Pressure”. 

• Compact, wall‐mounted design: Given its instant and small capacity nature (8L/min), this unit is suitable for point‐of‐use or single bathroom setups. One listing states “8 liter capacity for optimal water heating… Compact design… high water pressure compatibility.” 

• Adjustable temperature & flow: Some listings mention adjustable controls for gas and water flow to fine tune the temperature of output hot water and adapt to varying inlet conditions. 

• Suitable for Pakistani home conditions: The listing in Pakistan highlights that the unit is marketed in local stores, including features suitable for local water/gas supply. For example, one Pakistani site lists it under “Instant Gas Geyser – 6LTR / 8LTR / 10LTR” for Fischer. 

In practical usage, the Fischer FWH-8L is ideal when you want hot water instantly for a shower or basin without the bulk of a storage tank. Because it uses gas, make sure you have adequate gas supply (LPG or piped natural gas, depending on market) and proper venting/exhaust if required for safety. The copper burner/heat-exchanger combination means higher efficiency and potentially better lifespan versus lesser materials. Installation must respect minimum water pressure and safe ventilation. If you have low water pressure, check compatibility (some instant gas heaters require a minimum flow/pressure to ignite safely).
One potential limitation: Because it’s rated for ~8 litres per minute, it is best for a single shower or basin use; if multiple outlets or very high flow are required, you might need a higher-flow unit.
