The Hoval Mini-3H boiler / calorifier combination is a compact solution for your heating and hot water requirements. Dry back type flue box permits lower operating temperatures 3rd pass through the Thermolytic heat exchanger with regulators 2nd pass through baffle plate 1st pass into combustion chamber Enamelled calorifier shell Calorifier primary coil Mini-3H combination boiler The Mini-3 can be supplied as a combination boiler with an integral temperature controlled calorifier. This is available as either a 150, 200, or 300 litre unit. The enamel lined steel calorifiers are fitted with a built-in primary heating coil, providing rapid recovery of DHW, and insulated with 50mm polyurethane plastic foam within a steel Hoval red casing. Optional electric immersion heater A 3kW electrical immersion heater is available as an optional extra. Where required TopTronic controllers can be fitted. Burner acoustic cover Double hinge door with swivel arrangement for ease of servicing, even with low NOx burners with longer blast tubes. Burners suitable for natural gas, oil and LPG firing. Magnesium sacrificial anode Calorifier immersion sensor Calorifier insulation Note: This version is offered in the UK as a special. The standard combination unit has the calorifier on top of boiler. Please see dimensional details. Mg anode protection The DHW side of the calorifier is protected from corrosion by a Magnesium (Mg) sacrificial anode which is supplied on all combination units.
