The HeatMaster® C is a hot water generator linked to a condensing boiler
meeting the requirements of “HR-Top” standards in force in Belgium. The
boiler is certified in compliance with “EC” standards as a room sealed
appliance: C13(x) - C33(x) - C43(x) - C53 - C83(x) - C93, but it can also be
connected as an open appliance in category B23 or as an appliance operating
at positive pressure from the B23P category.
Connection type C63 (x) is prohibited in Belgium.
JACkET
The boiler is enclosed in a steel casing, which has been degreased,
had a phosphate treatment process and then stove enameled at 220 °C.
The inside of this casing is lined with a layer of thermal and acoustic insulation,
which minimizes losses.
HEAT EXCHANGER
The core of the HeatMaster® C features a new stainless steel heat exchanger
which is a result of exhaustive research and intensive laboratory tests.
This reflects almost 90 years of experience in the use of stainless steel for
heating and hot water generation systems. The specific geometry of the
exchanger has been calculated in order to obtain a very large Reynolds number
through all of its routes. The HeatMaster® C thus achieves an exceptional
output remaining stable throughout the boiler’s lifespan, given that it does
not produce any oxidation on the exchanger, which is manufactured entirely
of quality stainless steel.
BuRNER
ACV uses its BG 2000-M burner for the HeatMaster® C: this is a modulating air/
gas premix burner providing safe and quiet operation while limiting emissions
(NOx and CO) to an incredibly low level. Although the ACV BG 2000-M burner
is very modern, it uses proven technology and is manufactured using standard
spare parts that are easily available on the market.
TEMPERATuRE CONTROl
The HeatMaster® C is fitted with an “ESYS” regulator controlled
by a microprocessor, which handles the safety functions (ignition, flame
monitoring, temperature limitation, etc,) and the temperature control of the
boiler. The ESYS also features a weather dependent regulator. Simply connect
the outdoor temperature sensor, available as an option.
However, this regulator can also operate with a standard (on/off) room
thermostat. The temperature of the system is then dependent on the outside
conditions with compensation for the indoor temperature.
Two rotating buttons placed on the control panel are accessible to the
user, enabling adjustment of the temperature of the heating and domestic
hot water. By entering a specific maintenance code into the unit, qualified
installers may access certain parameters, in order to adapt the boiler to specific
requirements. In principle, these are factory preset for all normal applications.
Hot water generatIon
In addition to its exceptional capacities for hot water production,
the Tank-in-Tank system by ACV offers the following advantages:
- A solution to prevent limescale deposits: the corrugations allow
the tank to expand and contract during the heating cycle and thereby to
prevent the build-up of limescale deposits.
- Ensures that the hot water is free from legionella and bacteria:
the tank is fully immersed in the primary circuit and the domestic
water is permanently maintained at a uniform temperature of greater
than 60 °C.
- Exceptional resistance to water damage and corrosion: thanks to its
stainless steel design.
This HeatMaster® C also enables you to choose between two sanitary
function methods.
- Full priority mode: (factory preset) the boiler cuts the heating circuit
each time the domestic circuit requires it.
- Parallel mode: (only with a radiator heating circuit) the boiler
functions for heating and domestic hot water at the same time.
frost protectIon
The boiler is equipped with integrated frost protection: as soon as the outlet
temperature [NTC1 probe] goes below 7 °C, the circulator becomes active.
As soon as the outlet temperature is lower than 3 °C, the burner starts up until
the outlet temperature exceeds 10 °C and the circulator continues to run for
approximately 10 minutes.
If an outdoor temperature probe is connected, the circulator is activated when
the outside temperature drops below the preset threshold.
