FAQs
Is this heater truly internal and submersible?
Yes. It’s designed to sit inside the tub’s water volume or a dedicated internal chamber, reducing plumbing complexity and heat loss.
What tub size will 26 kW support?
26 kW is suitable for typical garden tubs; exact performance depends on water volume, insulation, ambient temperature, and cover use.
Do I need a special flue or chimney?
Yes. Use a high-temperature rated flue of the correct diameter and height, with safe clearances and weather protection per the manufacturer.
How do I maintain the heater?
Burn seasoned hardwood, remove ash regularly, check gaskets/seals, inspect the flue, and rinse exterior surfaces with fresh water after use to limit corrosion.
Can I install it myself?
Professional installation is strongly recommended to ensure correct sealing, flue routing, ventilation, and compliance with UK safety guidance.
