General questions
Yes, the multigebo meets the latest hygiene requirements for drinking water applications (UBA metal assessment basis for drinking water) and has an EPDM seal with DVGW certification for drinking water.

Sealants should only be used as soon as the water loss is higher - 3 litres of water loss/day. Only from this leakage quantity can enough active substances react with the environment so that the leakage can be sealed.
It can be used without any problems. The large water surface with air contact poses no problem.
GEBO Liquid sealants should be removed by flushing the heating system after successful sealing. One exception is heating systems operated with boilers. The GEBO Liquid Micro used here must be removed by flushing after 4 weeks at the latest.
Hot water storage tanks or the heat exchanger in the hot water storage tank cannot be sealed. In this case, the sealants have no contact with the CO2
Yes, but please note the following: Liquid requires a minimum temperature in order to be effective.
It is common for the temperature to fall below this when used in underfloor heating systems (the operating temperature here is usually around 40°C), but nothing stands in the way of application. However, if the temperature falls below this level and the moisture accumulates in the floor, the curing time will be extended by a few days
Yes, but it must be possible to create a separate small circuit (decoupled from the entire heating circuit).
The necessary operating temperature can then be generated by a mobile "heater".
In heating systems with buffer tanks, these must always be bypassed. As there is only a low volume flow in the buffer tanks, the active substances would settle at the bottom of the buffer tanks.
Liquid sealants can also be used with deionised water (demineralised water). In this case, the system should be rinsed and refilled with deionised water after sealing.
Applications in solar systems are possible, please observe the work instructions/confirmation
GEBO Liquid sealants cannot be used in conjunction with systems filled with antifreeze. The sealants may react with the antifreeze under certain circumstances.
Liquid S can be used in condensing boilers. However, the water content must be changed, as aluminium/silicon heat exchangers are often used in this type of system. The increased pH value would damage aluminium components.
All GEBO Liquid products are sensitive to frost and must be stored accordingly.
If the heating system is heavily soiled, the system must be cleaned and flushed beforehand. Liquid Clean Art. No. : 75052 can be used for this preparatory work. An annual inspection must be carried out. This is carried out with the aid of a conductivity meter. The correct value should be 1250 micro-Siemens above the filling water.
The sealants are introduced into the heating system using a filling pump
GEBO Liquid products can be disposed of via the sewage system after they have been mixed with water in a ratio of 1:100.
Water volume in various heating systems:
Water content in litres per kW heat output of the heat generator.
- Underfloor heating approx. 21.5 litres
- Gravity heating with cast iron radiators approx. 12.9 litres
- Low-temperature heating with panel radiators approx. 8.6 litres
- Mixed systems with panel and cast iron radiators approx. 10.5 litres
The values given are approximate
The exposure time depends on the location/size of the leak. Sealing of boilers is usually completed within a few hours. When sealing underfloor heating systems, and in the case of small leakage quantities, sealing can take several days.
In principle, yes, but if the system has been weakened by corrosion, leaks can occur again and again after some time. This is usually due to the next "weakest" point becoming leaky. However, this is the exception.
Please note that sealants cannot be used as a preventative measure, as the individual active ingredients are consumed.
For ideal sealing, the heating system should be in operation. Circulation ensures that the sealant reaches everywhere.
The various sealants differ in the amount of active ingredients they contain
- Liquid Micro is suitable for a water loss of up to 10 litres per day
- Liquid S is suitable for a water loss of up to 200 litres per day
- Liquid L is suitable for a water loss of up to 500 litres per day
- Liquid XL is suitable for a water loss of up to 800 litres per day
A mixing ratio of 1:100 applies to all liquid products
GEBO Liquid products for the heating sector can be stored indefinitely.
The material must be removed immediately with water. Subsequent cleaning is not possible. Do not use cleaning agents under any circumstances.
