TRINITY - sophisticated
solutions for demanding customers
Warmth from nature
The beauty of TRINITY air inserts is not everything. Thanks to the continuous development of the HITZE brand, many other innovative solutions have been obtained, which distinguish this fireplace from the others available on the market. The first one is the modern mechanism of opening the fireplace - thanks to the guillotine with service access, the use of the insert is fully safe and provides protection for the youngest.

What is more, thanks to a well thought-out construction, the user does not have to be afraid of smoke going back to the room when opening the insert.

Of course, the TRINITY fireplace inserts also have a high heating efficiency, which has been achieved with the proven HITZE solutions. These include a wide hearth, flames that increase the area of heat accumulation and exchange, and two ceramic concrete deflectors that enable longer afterburning of the fuel particles and thus increase the combustion temperature. Special attention should also be paid to an independent aerated afterburning system and a fully adjustable cast-iron flue pipe, which allows exhaust fumes to be discharged in any direction - this gives full safety and makes the TRINITY fireplace insert fully ecological.
What is more,
every fireplace in this series:
  • is made of the highest quality steel, which makes it functional and elegant over many years;
  • is very easy to clean, thanks to the EASY CLEAN system, the clean TRIO glass with air curtains and a large ash container;
  • is equipped with an innovative air intake system, thanks to which it is fed independently through three channels - under the grate, bottom air curtain and top air curtain and afterburner;
