BOILER
2.1
Operation and components
The Avanta Plus is a high-efficiency system or combi boiler for
domestic space heating and hot water production.
The combi boiler provides space heating and contains a plate
heat exchanger, three way diverting valve and additional components to supply instant DHW direct from the boiler on a priority basis without the need for storage
The system boiler provides space heating and can be used in
conjunction with a cylinder/calorifier and other external controls
to provide DHW indirectly
Both models have helical stainless steel heat exchanger’s c/w
a premix burner ensuring high heat transfer efficiency with
flue gases being discharged via the concentric flue system.
Condensation which forms during the combustion process is
discharged via the siphon on the underside of the boiler.
An intelligent advanced boiler control unit (‘abc®’) provides all
the necessary safety and operational safeguards using internal
and external sensors etc to ensure that the boiler operates
reliably with maximum efficiency

demand) to ensure faster response. The Eco mode
disables this option therefore uses less energy.
 No hot water
Beware; the system boiler in combination with an external calorifier will not warm up the calorifier in the Eco-mode.
So, if the calorifier is empty, the tap water will be cold.

TOPPING UP, BLEEDING AND DRAINING SYSTEM
It may be necessary to bleed the central heating system or top
it up with water to ensure optimum operation of the boiler and
central heating system. If the water pressure is less than 1 bar,
the system has to be topped up with water. This section provides information on topping up, bleeding and draining.
5.1
Topping up the central heating system
Disabling the boiler
Before the central heating system can be topped up, the boiler
must be disabled. Proceed as follows:
•

Switch off the boiler.
Topping up the central heating system
The Remeha Avanta Plus runs best with a water pressure of
between 1.5 and 2 bar (see the water-pressure meter at the
bottom of the boiler). If the water pressure falls below 1 bar,
the system has to be topped up with water.

Air gets into the central heating system when topping up with
water. Bleed the central heating system as described in par.
5.2. After bleeding, the water pressure may be below the
required level again, so the system has to be topped up with
water. Topping up and bleeding twice ought to be sufficient to
reach the correct water pressure.
Consult the installer if the central heating system has to be
topped up more than three times a year.
Enabling the boiler
Once the central heating system has been topped up, enable
the boiler again, see section 7.

DISABLING THE BOILER
The boiler must be disabled before any maintenance or repairs
are carried out. If the central heating system is not used for
a long time (during the holidays, for instance, or periods of
milder weather) it is advisable to disable the boiler.

•
•
Set the room thermostat to a low temperature, e.g. 10°C,
Switch setting p4 to 1 (Eco mode), this will switch off
the heat retention function.
Now the boiler will only start working to protect itself against
freezing.
With an external frost protection connected, the boiler can also
prevent the central heating system from freezing.

TIPS FOR MAINTAINING THE BOILER AND CENTRAL HEATING SYSTEM
•
Check the water pressure of the central heating system
several times a year. If the water pressure is too low, top
up with water (see par. 5.2). The optimum pressure is
between 1.5 and 2 bar.
•
Check radiators for leaks and (particularly in damp
rooms) for rust. Treat patches of rust as early as possible.
•
Open and close radiator valves fully several times a year.
This ensures that valves continue to turn smoothly.

 Cleaning
The inside of the boiler may only be cleaned by the installer.
 Service contract
Soiling may reduce the performance of boiler components.
For this reason the boiler and central heating system must be
inspected once a year by the installer. Ask the installer or the
utility company about taking out a service contract.

ENERGY SAVINGS AND ENVIRONMENTAL PROTECTION
Comfort, cost savings and environmentally-aware use can go
hand-in-hand. This sections contains:
•
tips on saving energy
•
tips on correctly setting the room thermostat.
9.1
Tips on saving energy
•
Ensure that the room in which the Remeha Avanta Plus
is fitted is well ventilated. Do not seal up ventilation openings.
•
Place radiator foil on walls behind radiators; this reflects
heat which is otherwise wasted.
•
Do not box radiators in or hang curtains in front of them.
•
Insulate pipes in rooms which do not have to be heated
(cellars and crawl spaces).
•
Close radiator valves in rooms which people are not
using.
•
Do not let hot (and cold) water flow unnecessarily.
•
Fit an economy shower head; this can save up to 40%
energy.
•
Take a shower instead of a bath; a bath uses twice as
much water and energy.
9.2
Room thermostats and settings
The room thermostat is available in the following designs:
•
•
•
2-wire on/off thermostat
Modulating thermostat (in combination with a timer clock)
Timer-operated and programmable thermostat
The thermostat type and settings affect the total energy consumption.
LTALW7H000222a
LT.AL.W7H.000.222
A few tips:
•
A modulating thermostat, possibly in combination with
thermostatic radiator valves, is energy-efficient and offers
a high level of comfort; this combination enables the temperature to be set individually for each room. However, do
not fit a thermostatic radiator valve in the room where the
room thermostat is located.
•
Opening and/or closing thermostatic radiator valves fully
results in undesirable temperature fluctuations; turn the
thermostat control or valve up or down in small steps.
•
Set the thermostat to its night-time level (approx. 15°C)
half an hour before going to bed. This saves fuel costs
and energy.
•
Set the thermostat to a lower level well before leaving a
room.
•
Set the water temperature p1 lower in summer than in
winter (e.g. 60° and 80°C, respectively) if an on/off thermostat is being used.
•
When setting a timer-operated and programmable thermostat, don’t forget to take account of holidays and days
when no one is at home.

EXPANDING THE CENTRAL HEATING SYSTEM
Connecting thermostats
A 2-wire on/off thermostat (e.g. the Remeha Celcia 10) or to a
modulating thermostat (e.g. the Remeha Celcia 15 or 20) can
be connected to the Avanta Plus. Consult the installer about
connecting the thermostat you have chosen.
Connecting an under floor heating system
A under floor heating system can be directly connected to the
Avanta Plus (provided it is sealed to prevent oxygen diffusion).
Consult the installer about connecting to a floor heating system.
Use of solar panels
The Remeha Avanta Plus is suitable for use as a post-heater
for solar panels. Consult the installer about installing a solar
panel.
