Fischer R-50 ELECTRIC WATER HEATER DUAL POWER (HEAVY DUTY) Single welded tank Wattage control

Fischer R-50 Dual Power is a 50-litre electric storage water heater designed for heavy domestic use, offering flexibility, durability and energy-control features. Key highlights include:

• Large 50 L storage capacity — suitable for a medium-to-large household bathroom or for multiple uses (e.g., shower + basin) within a single unit.

• Dual Power / Wattage Control — The unit allows adjustable heating power (for example, modes of ~800 W / 1200 W / 2000 W) so you can moderate energy consumption depending on hot-water demand or electrical supply constraints. 

• Single welded inner tank — Heavy duty construction with one welded steel tank (rather than multiple seams) to improve durability and reduce risk of leaks. 

• Fully insulated tank — Insulation ensures that stored hot water retains temperature, reducing standby losses and improving efficiency. The unit is marketed as “fully insulated with full tank capacity as per rating” meaning you really get the rated 50 L and not a reduced internal volume. 

• Thermal safety cut-outs — Safety features such as thermostat cut-out to protect against overheating are included. 

• Imported major parts — Fischer emphasises that major components (such as heating element, thermostat, insulation) are imported, which may raise build quality above local budget models. 

• Designed for Pakistani market — The Fischer product listing specifically lists 40 L, 50 L and 60 L variants under the same “New electric water heaters” family. 

In practical usage, this water heater is ideal for a family with an above‐average hot water need, where you already have (or are willing to have) the storage type heater. The wattage control feature gives you flexibility in managing electricity usage: when demand is low or supply is weak, you may select a lower wattage; when you need faster heating or more hot water, you switch to full power. The heavy duty tank and insulation mean better durability and less heat loss, which are important in environments like Pakistan where electricity cost, water quality and reliability are major concerns.

Installation will require appropriate wiring, proper supporting wall / bracket (when full of water, 50 L + heater weight is substantial), and good plumbing (including a safety valve). Because this is a storage heater rather than an “instant/flow-through” type, you’ll start the unit ahead of time (so the 50 litres heat up) and you’ll have hot water ready to use; once it’s heated, the insulation helps retain the heat for a time.
