ENVIROPAK Condensing Boilers...

The Hunt ENVIROPAK range of condensing boilers are designed to provide an effective packaged solution, while still being at the forefront of energy efficiency.

The range is based on a firetube wet back three pass principle with the addition of a heat recovery condensing circuit.
 
Assuming an inlet gas temperature of 200ºC being provided to the heat recovery section, efficiencies of greater than 94.5% are achieved when measured in accordance with BS7190 and BS845.

They are manufactured in our Hunt Boilers' Victorian workshops and in standard form are suitable for up to a 540 kPa working pressure. (higher pressures are available)  
 
The key features of the product range include:
 
Significantly lower fuel costs and lower greenhouse gas emissions
 
Minimal additional pressure drop is induced so standard forced draft burners are suitable
 
Designed to be fully compliant with the requirements of AS1210 and AS4343
 
All condensing areas manufactured from suitable grades of stainless steel

Minimal refractories: wet back principle

Low maintenance

Complete water space around furnace

Fully packaged complete with burner and control panel

Low operating noise levels
