INTRODUCTION

General

BUFFER TANKS aren’t planned to be equipped with an electric heating resistance immersed in the device (immersion heater or any other electric heating system).

• Must be integrated on the device or the installation but near the latter :
• A safety valve calibrated at 3 bar (= maximum operating pressure of the device) and installed in such a way that no valve or any hydraulic device can accidentally isolate it from the device which is equipped with an electric heating resistance.

The buffer tank makes it possible, by increasing the volume of water in the installation, to reduce the number of start-ups of the boiler (and/or the heat pump) to make it sustainable. For heat pumps, the buffer tank also serves as a heat reserve for the defrost cycles.
Used in a decoupled system, it allows the circulator that equips each circuit (boiler, heat pump, radiator and underfloor heating) to flow independently of each other.
By greatly reducing the speeds, it also allows the settling of the sludge and the purging of the air of the installation.

INSTALLATION

In decoupling buff er (example)

In heating buffer tank (example)

MANDATORY TREATMENT OF THE HEATING CIRCUIT

Central heating installations (radiators, underfloor heating, etc…), must be desludged (existing installations older than 6 months before the boiler is replaced, or after any work is carried out) and rinsed (both new and existing installations). Use an appropriate product to eliminate the debris (soldering waste, copper, filings, metallic particles, etc…) associated with the set-up of the installation and from chemical reactions between the different metals.
Furthermore, it is important to protect (in both new and existing installations), the central heating installations from risks of corrosion, limescale and microbiological development by using a corrosion inhibitor that is suitable for all installation types (cast iron radiators, PEX underfloor heating, …).

Treatment

We recommend the use of products in the SENTINEL range for preventative and curative treatment of the heating circuits:

For new installations (less than 6 months)

1. Clean the installation with a universal cleaner to eliminate debris caused by the installation process (copper, fibres, filings, soldering waste, etc…).
   Example: SENTINEL X300 or SENTINEL X800

2. Thoroughly rinse the installation until the water runs clear, with no traces of impurities left.

3. Protect the installation against corrosion with a corrosion inhibitor
   Example: SENTINEL X100 Or against corrosion and frost with a corrosion inhibitor with an anti-freeze additive.
   Example: SENTINEL X500 or SENTINEL R600

For existing installations (older than 6 months)

1. Desludge the installation with a desludging product to eliminate any sludge from the installation.
   Example: SENTINEL X400 or SENTINEL X800

2. Thoroughly rinse the installation until the water runs clear, with no traces of impurities left.

3. Protect the installation against corrosion with a corrosion inhibitor.
   Example: SENTINEL X100
   Or against corrosion and frost with a corrosion inhibitor with an anti-freeze additive.
   Example: SENTINEL X500 or SENTINEL R600

The corrosion inhibitor allows to:

• protect against the formation of limescale,
• prevents different types of corrosion (galvanic oxidation, «pitting» or «pin-hole», acidic pH),
• prevents, in new installations, the formation of sludge and prevents the formation of bacteriological proliferation (algae in the low-temperature network)
• prevents the formation of hydrogen and limescale (lowers the sound made by the generators).

Treatment products from other manufacturers can be used if they guarantee that the product is appropriate for all the materials used in the appliance, and if they offer an efficient resistance to corrosion. To find this information, refer to the user manual.
The products used for the treatment of the heating water must comply with the local regulations in effect or the regulations in effect in the country of installation and use.

Frost protection

If the boiler(s) and/or heat pump(s) must be turned off during the winter period (ex: accidental stop; secondary residence; etc…), frost protection is necessary to avoid having to drain the hydraulic circuit of the heat pump which is located outside of the residence. For frost protection use a «mono propylene glycol» anti-freeze with a corrosion inhibitor additive.
In case the HRC70 heat pump is not working, (exterior temperature < – 20°C) it is automatically protected from freezing as the heat pump controls the circulator to maintain heat in the heating circuit which then has its temperature maintained by the Pilot’s electrical back-up or back-up boiler.

Quality of filling water
Filling using rain or well water is prohibited.
Filling of the heating circuit must be done only using untreated water (no water softener) from the drinking water network :

1. Clearwater without any deposits.
2. Ideally 15°f < TH < 20 °f (or french °).
3. Chlorides (Cl—) < 50mg/litre.
4. Sulphates (SO²4—) < 50mg/litre.

Chlorides and sulphates naturally present in the water cause pitting (a phenomenon of localized corrosion that eventually leads to the perforation of metals).
The water in the drinking system generally has a hydrogen potential (pH that determines its acidity or alkalinity level) close to neutrality (pH≈7) and therefore contains almost no dissolved carbon dioxide or carbonates.
As soon as the filling water of the installation rises in temperature the decomposition of the bicarbonates produces carbon dioxide which will be evacuated from the installation by the air traps increasing the pH value accordingly.

Facility degassing

• Dissolved oxygen in heating water is a powerful vector of corrosion by oxidation of metals.
• This aeration also contributes to the proliferation of organic sludge.
• Particular attention must be paid to the control of the non-aeration of the heating system: expansion tank and in particular to the synthetic materials used.

ANNUAL MAINTENANCE OF THE HEATING CIRCUIT (and cleaning of filters after first use)

It is MANDATORY to carry out an annual inspection of the quality of water :

1. Cloudiness: a visual test of the quality of water in the heating circuit which informs on the general state of the installation.

2. Sludge levels: desludge if necessary.

3. Limescale: Descale if necessary.

4. pH must be between 8.5 and 10 for installations made of steel. If the pH is higher than the limits shown, the metal will corrode.
   The pH of metals in their natural state is the following :

5. Water conductivity < 800 μS/cm (micro Siemens per centimetre) that provides information on total water mineralization.

Clean the filter several times

1. After the first use of the appliance (take care to stop the circulators before cleaning).
2. Annually.
   Replace the filter if necessary.

Refilling the water in the circuit dilutes the corrosion inhibitors. The water added must be limited to 5% of the total volume of the circuit. The total amount of water added to the circuit (filling and refilling) must be accounted for.
Automatic refilling is prohibited.

If the hydraulic circuit is protected using an anti-freeze product:

1. Regularly inspect the pH level and the % of glycol in the installation.
2. Never top up the glycol in an existing installation before having verified, by measuring the pH level, that the drop in the % of glycol is not due to a deterioration of the glycol.
3. When the pH becomes acidic (pH < 7), replace all of the glycols after having already drained and rinsed the installation.

APPENDIX

Help with the sizing of the buffer volume

Depending on the water capacity of the hydraulic installation, it may be necessary to add a buffer volume to prevent the operation of the boiler (s) or the heat pump with short cycles and thus preserve them.
Boilers and heat pumps that operate “on or off ” have a minimum operating time of “Gemini” and an operating differential “ΔT” (temperature difference between on and off ).
The minimum total volume that the hydraulic installation must satisfy is :
Vmini (litres)= P (kW) × time mini. (minutes) x 1000 1,163 × ΔT (°K) 60

Count the volume of the following items for the total volume of the installation :

1. the boiler (only the one with maximum power in the case of a coupling)
2. the buffer (or decoupling) bottle
3. the pipes (…)
4. the volume of the emitters of the circuit (s) that are permanently irrigated (without thermostatic valves or mixing valves)

For information, the volume of water contained in the installation is to be taken into account depending on the type of emitters permanently irrigated is given in the table below as an indication :

Type of transmitters| An equivalent volume of water (litres / kW of installed power)
---|---
Cast iron radiator| 13
Steel radiator| 10
Convector| 7
Air heater| 5
Floor Ø 13×16| 12
Floor Ø 16×20| 17

• For boilers, take the power of the highest stage, or even the total power of the boiler if it operates on all or nothing.
• Usually, the minimum running time is around 6 minutes and the operating differential is around 7 ° K.
• For heat pumps, take the power at the lowest speed (30% for example for an inverter heat pump) or the power at + 7 ° C (outside) and 35 ° C (water outlet). For heat pumps with 2 compressors, take the power of the compressor which operates at + 7 ° C (outside) and 35 ° C (water flow).
• Usually, the minimum running time is around 6 minutes and the operating differential is around 5 ° K.

When several boilers or heat pumps are coupled, only the power of a single boiler (that of maximum power) should be taken into account and not the power of all the generators.
