Instructions Part Number IN1232 Ed 1

Functional Description and Technical Features

The EVO AQUA is an appliance designed to be ﬁred speciﬁcally

by wood pellets (must comply with EN Plus). This appliance is

a boiler (central heating).

Heat energy is transferred via the stove surface (the majority

of radiant heat arises via the inspection window) to the room

and via the water heat exchanger to the heat dissipation

system. For example, hot water is “produced” and the heat is

dissipated via this medium to the buffer cylinder.

In heating mode, you can switch on the boiler and select the

required boiler output or temperature; the system can be

switched on or off automatically or the necessary output stage

can be adjusted automatically via external control units.

The comb grate is cleaned automatically when the system

starts up either manually or automatically. The wood pellets

are conveyed to the combustion chamber via an ascending

worm screw (with an intermediate rotary valve as burn-back

protection) and ignited by electrical ignition devices.

The screw conveyor delivers pellets automatically. The oxygen

necessary for combustion ﬂows into the combustion chamber

in a controlled manner. The combustion gases burn out in the

combustion chamber and the downstream ﬂue gas ducts, the

heat being released via heat exchanger surfaces. A suction

fan (which may generate some noise at high and low control

settings), adjusted to the fuel quantity and the necessary combustion air, ensures a stable vacuum in the boiler

and transports the ﬂue gases safely to the ﬂue.

The necessary air quantity is controlled via the combustion temperature.

System Requirements

The stove is always combined with other devices and therefore have speciﬁc system requirements to ensure

trouble-free operation. A number of very important requirements are described in detail in the following

paragraphs.

In the preliminary stages a well-thought-out installation plan should be drawn up by a qualiﬁed installer or

heating engineer, so that individual system components can be adapted to each other and the required overall

solution achieved.

Hydraulic balancing of the system as a whole is essential for correct operation.

Application Possibilities

- as a main heating system: Operation as central heating appliance in low-energy and single-family homes

including water heating.

- as an additional heating system: Operation in addition to other heat sources.

This distinction is important when designing the system and selecting components (solar system, buffer

cylinder, etc.). Make sure you observe the information in the assembly instructions.

Instructions Part Number IN1232 Ed 1

As a general rule, a heat load calculation must be performed by the qualiﬁed heating engineer for every boiler

installation location.

Experience shows that a heating system is operated at rated load for a total of approx. 1800 hours during a

heating season (total rated load and partial load hours added together).

E.g.: EVO 9: rated output 10 kW * 1800 h = 18,000 kWh per year; pellet caloriﬁc value approx. 4.8 kWh/kg

Pellets required per year approx. 18,000 kWh / 4.8 kWh/kg = 3750 kg

Note: Domestic Water Heating in Summer Operation

The EVO AQUA is distinguished by an especially low radiation output in the living room and by a very good air

to water capacity (9 kW: approx. 13:87%; 15 kW: approx. 10:90%). However, as the radiation output cannot be

entirely avoided for physical reasons, domestic water heating during the summer months can lead to undesirable

heating of the installation location. If this heating is not required, we recommend combined operation with

alternative domestic water heating systems (e.g. solar, immersion heater).Your heating specialist will be happy

to advise you.

Note: Heating Surfaces/Radiators in the Installation Room

In transitional heating periods (spring, autumn), when using in combination with additional heat sources (e.g.

solar system with buffer cylinder), it is possible that the heating appliance may not operate as sufﬁcient heat

is supplied by the additional heat source.

If there are no heating surfaces (e.g. radiators) in the installation room, the room would not be heated in this

case. For this reason, make sure that there is always a corresponding heating surface in the installation room.

Water System, Output Consumption

Heating requirements must ensure that the appliance operates for 1.5 to 2 hours at least 50% of the rated

output per combustion cycle.

Room and Ambient Temperatures/Humidity

The system is designed for operation in living rooms with normal humidity and ambient temperatures of +5°C

to +40°C.

At room temperatures below 5°C, suitable frost protection must be provided in the water circuit.

The system is not splashproof and must not be installed in wet rooms.

Flue Connection

It is imperative that the appliance is connected to a ﬂue suitable for solid fuels. The ﬂue draught must always

be between a minimum of 5 and a maximum of 15 Pa. If the ﬂue draught is too high (>15 Pa), we recommend

ﬁtting a draught regulator.

Combustion Air Supply

a) The appliance operates as an open ﬂue system. An adequate combustion air supply is essential.

b) It is possible to ﬁt an external combustion air supply to the EVO AQUA during installation or at a later date.

i.e. all the combustion air is drawn from outside of the building.

Pellet Quality

Wood pellets are 100% wood residues in their natural state (wood shavings, sawdust, etc.). Dry wood residues

are chopped up and compacted to form wood pellets. Pellet quality is deﬁned by EN Plus.

In practice: 2 kilograms of wood pellets correspond to approximately one litre of heating oil . Wood pellets must

be transported and stored completely dry. If they come into contact with moisture, pellets swell up considerably

as wood is hygroscopic (i.e. it constantly exchanges humidity with the environment).

Instructions Part Number IN1232 Ed 1

Only pellets produced to ENplus standard are suitable for this appliance.

How can you recognise good quality wood pellets?

Good quality: the surface looks smooth with a semi-matt sheen, pellets of equal

length, no dust.

Lower quality: longitudinal cracks, high proportion of extremely long or short pellets,

high dust content.

How can we check the compaction quality of the pellets quickly and approximately?

Put a handful of pellets into a glass of water.

Good quality: pellets sink; due to their high density compared with water.

Lower quality: pellets ﬂoat; due to their low density compared with water.

Return Flow Temperature Control

A return ﬂow temperature control is essential.The return ﬂow temperature must be at least 55°C at the appliance

return ﬂow connection (optimum value 60°C), otherwise soot and tar formation, with resulting corrosion, can

occur. Euroheat offer special connection assemblies for this purpose which can be positioned inside or outside

the boiler. Details can be found in the separate installation instructions.

Buffer Cylinder/Accumulator

A buffer cylinder/accumulator is essential for efﬁcient operation of this appliance. By using a buffer cylinder/

accumulator, the boiler can always be operated in the optimum output range, thus minimising consumption

and pollutant emissions. This also extends the service life of the system and wearing parts. The minimum size

of the cylinder should be 9kW Evo Aqua 400L/15kW Evo Aqua 500L.

Buffer Sensors

We recommend installation with buffer sensors. The stoves operation is controlled via these sensors, one sensor

is mounted in the buffer top and one at the bottom. When the top sensor drops below a preset temperature,

normally 60°C, the stove starts to operate. When the lower sensor reaches a pre set temperature, normally

65°C, the stove stops operating.

Cleaning, Maintenance and Servicing

This appliance is a wood-ﬁred boiler. Ash and soot accumulate when solid fuel is burnt, which means that

periodic cleaning and servicing is essential. If this is not carried out, faults can arise for which we cannot accept

any liability. Only a clean and correctly adjusted boiler is an efﬁcient boiler. A coating of only 1 mm of dust on

the heat exchanger surfaces increases fuel consumption by approximately 7%.

Mains Voltage/Power Supply

230 VAC/50 Hz. Voltage ﬂuctuations from -15% to +10% are admissible.

Visionconvey AIR Pellet Conveying System for EVO AQUA (suction conveying system)

The EVO AQUA boiler can be equipped or retroﬁtted with an automatic pellet conveying system which avoids

the need to top up the inbuilt hopper with pellets manually.

The design of the storage room, assembly and operation of this system are described in the separate technical

documentation accompanying the discharge system.

Instructions Part Number IN1232 Ed 1

Prior to First Lighting

Prior to lighting all connections (water,ﬂue pipe and electrical) in the system must be checked. If the system is

cold, the system pressure must be at least 1.5 to max. 2 bar.

Before operation boilers must always be ﬁlled with water and connected to the heating system. Safety devices

must not be bypassed, sealed off or removed and must be ready to operate.

Always keep the combustion chamber door closed, even when cold.

When handling the system, always use the supplied heat-resistant glove.

Ensure that there are no objects in the combustion space or combustion chamber.

Pellets (min. 5 kg) may only be admitted to the storage tank after full installation according to the assembly

and installation instructions.

All steel and cast parts are painted with highly heat-resistant paint.

On initial heating the paint dries out, which may cause a temporary increase in the development of odours

and fumes.

Please note the following points:

No individuals or pets should be present in the room.

Ensure the room is well ventilated, so that the fumes can escape unhindered.

During the hardening period the paint is soft. To avoid damaging painted surfaces, do not touch.

The paint will harden during operation.

Operating Modes

The boiler can be operated in two different operating modes: boiler mode and heating stage/buffer mode. The

two operating modes are adjusted from the basic level of the control system.

Boiler Mode

Boiler mode is stored as a standard mode in the control system and is used until the operator speciﬁcally

changes to stove mode. In this operating mode the boiler adjusts its heating output according to pre-deﬁned

control variables according to requirements, e.g. via the weather-dependent control unit, a room thermostat,

etc.

Heating Stage/Buffer Mode

In this operating mode the boiler operates with a ﬁxed output stage (output stages are deﬁned with the letter

H, e.g.: H 70 = 70% of rated output) which is adjusted individually by the customer. This output control is

continued until the customer returns to boiler mode.

An inbuilt safety device guarantees that the boiler switches off if the maximum temperature is exceeded. (This

can occur if you have selected a high output stage and the system can’t take any more power).

Once the boiler has cooled down, it starts again automatically with the selected output stage.

Instructions Part Number IN1232 Ed 1

Operation and Heating Mode

General

The boiler is operated or controlled via the control unit installed on the

left side of the boiler casing.

The control unit has a two-line display which is used to read off the boiler
