The Ignis-V80 is a professional-grade, upright wood-fired swimming pool and hot tub heater delivering a powerful 80 kW of heat output — built for pools and hot tubs from 2.5 metres (8.2 ft) in diameter and above. Crafted from high-quality, seawater-resistant marine aluminium, this heater is engineered for durability, efficiency, and long-term performance in outdoor environments across the UK and Europe.
Unlike stainless steel alternatives, marine aluminium offers approximately 15× better thermal conductivity — making the Ignis-V80 up to 30% more efficient at transferring heat to your water. The 3 mm thick aluminium shell is twice the thickness of typical stainless steel furnaces, while still being 30% lighter. Aluminium also holds its shape over time — stainless steel heaters can warp and become misshapen with prolonged use.
Water circulation operates on the natural thermosiphon principle — rising hot water creates flow without requiring a pump. However, to ensure optimal and consistent flow, we recommend installing a low-speed electric pump with a flow rate of 1,500–2,500 litres/hour and water pressure up to 0.4 bar.
The unit ships complete with a 2-metre stainless steel chimney (two-part), manometer, thermometer, and automatic air separator — everything you need for a straightforward installation.

What size pool or hot tub is this heater suitable for? ⌄
The Ignis-V80 is designed for swimming pools and hot tubs with a diameter of 2.5 metres (8.2 ft) and above. Its 80 kW output makes it ideal for large-volume water heating in both residential and commercial settings.
Do I need electricity or a pump to operate this heater? ⌄
The heater naturally circulates water using the thermosiphon principle — no electricity is required for basic operation. However, to ensure smooth, consistent water flow we strongly recommend a low-speed electric pump with a flow rate of 1,500–2,500 l/h and max water pressure of 0.4 bar.
Why is marine aluminium better than stainless steel? ⌄
Marine aluminium conducts heat approximately 15× more efficiently than stainless steel, making this heater up to 30% more effective. The 3 mm thick shell is twice the thickness of standard stainless steel units, yet the heater is still 30% lighter. Aluminium also retains its shape over time — stainless steel can warp and deform from prolonged heat exposure.
Can I use chlorine or pool chemicals with this heater? ⌄
Chlorine is not recommended with aluminium heaters. For any other pool chemicals, please verify they are certified safe for use with marine aluminium before use. Incompatible chemicals can cause irreparable damage and will void the warranty.
What must I do before lighting the heater? ⌄
Always fill the heater completely with water before lighting it. Starting the fire without water inside will permanently damage the unit and void your warranty. Never operate the heater dry under any circumstances.
How do I protect the heater during winter? ⌄
When outdoor temperatures reach -1°C or below, fully drain the heater using the drainage tap on the underside of the unit. Water left inside at freezing temperatures can cause irreversible damage that is not covered under warranty.
What is included in the box? ⌄
The Ignis-V80 ships as a complete kit: the 80 kW upright heater unit, a 2-metre stainless steel chimney (two-part), a manometer, a thermometer, and an automatic air separator. No additional core components are required for installation.
