Product Information
Full details
The Wijas P35 instant water heater is designed for users needing compact, on-demand hot water for small spaces like under sinks. Its key benefit is its incredibly small size, making it ideal for installations where space is limited. A potential caveat is its 3.5kW power rating, which is suitable for single-point use but may not be sufficient for high-demand applications. This guide covers its features, use, setup, and troubleshooting.

FAQs
What is the primary use for the Wijas P35?
The Wijas P35 is ideal for providing instant hot water to a single outlet, such as a wash basin, in locations where space is limited.
Is this water heater suitable for a shower?
No, the 3.5kW power rating is generally too low to provide a satisfactory hot water flow for a shower, which typically requires higher power.
What electrical supply does it require?
It requires a dedicated electrical circuit with an appropriate amperage rating. Please consult the installation manual for specific requirements.
How does an instant water heater save energy?
Instant water heaters only heat water when you turn on the tap, unlike storage tank heaters that continuously heat and maintain a volume of water, thus saving energy.
Can I install this myself?
While some DIY installation is possible, electrical and plumbing connections should ideally be performed by a qualified professional to ensure safety and compliance with regulations.
What is the weight of the unit?
The unit weighs approximately 1.98 pounds.
What is the warranty period?
Please refer to the product manual or the retailer's information for the specific warranty period and terms.
Troubleshooting
No hot water produced
Check that the power supply is on and the circuit breaker is not tripped. Verify water flow is adequate and the unit is correctly connected to the cold water supply.
Water is not hot enough
Ensure the flow rate is not too high for the unit's 3.5kW capacity. Check that the temperature setting (if applicable) is correct and that the incoming water temperature is not excessively cold.
Leaking connections
Turn off the water supply and power. Tighten all plumbing connections. Replace any worn washers or seals if necessary.
Unit not turning on
Confirm the power source is active and the unit's internal protection mechanisms have not been triggered. Check wiring integrity if comfortable, otherwise consult a qualified electrician.
