Description
IBO IBOMAT API 25/55 – return protection pumping group
IBOMAT API 25/55 is a complete IBO return protection pumping group designed for direct installation on the return pipe of a solid-fuel boiler or a fireplace with a water heat exchanger. The integrated TSV3B thermostatic valve keeps the return water temperature above the condensation threshold, effectively protecting the heat exchanger against low-temperature corrosion and extending the boiler’s service life.
Who it is for
- Installers of solid-fuel boilers and fireplaces – the ready-to-install device with a complete set of components (valve, pump, insulation, thermometer) eliminates the need to select and connect separate components; it installs directly on the return pipe.
- Heating system designers – the TSV3B valve with automatic bypass balancing does not require an additional balancing valve, simplifying the design of the hydraulic system.
- Users of wood- and coal-fired boilers – protecting the heat exchanger against condensation and tar buildup results in higher combustion efficiency and less frequent servicing.
- Investors and developers – protection against low-temperature corrosion significantly extends the boiler’s service life, reducing the total operating cost of the heating system.
Application
IBOMAT API 25/55 is designed to protect solid-fuel boilers and fireplaces with water heat exchangers against low-temperature corrosion. The group is installed on the return pipe of the water heat exchanger and keeps the temperature of the water returning to the boiler above the valve’s opening temperature, preventing flue-gas condensation on the surface of the heat exchanger. Depending on the version, the maximum supported boiler output is 46 kW (version 45), 42 kW (version 50), or 36 kW (version 55).
The built-in IPRO API 25-60/180 circulation pump forces the heating medium to circulate, while the integrated TSV3B valve with a thermostatic insert automatically mixes cold return water from the system with hot water from the boiler bypass – without the need for an external balancing valve. The working fluid may be water or a glycol solution with a maximum concentration of 50%.

Frequently asked questions (FAQ) – IBOMAT API 25/55 return protection pumping group
What is the IBOMAT API 25/55 used for, and why is return protection important?
IBOMAT API 25/55 protects a solid-fuel boiler or a fireplace with a water heat exchanger against low-temperature corrosion. When cold return water enters the boiler without being preheated, water vapor from the flue gases condenses on the heat exchanger surface, causing corrosion and tar buildup. IBOMAT keeps the return temperature above the condensation threshold, increasing combustion efficiency and the boiler’s service life.
How do the IBOMAT 45, 50, and 55 versions differ?
The versions differ in the opening temperature of the TSV3B thermostatic valve and the maximum supported boiler output. Version 45 opens at 45°C and supports boilers up to 46 kW, version 50 opens at 50°C and supports up to 42 kW, while version 55 opens at 55°C and supports up to 36 kW. The appropriate version depends on the boiler manufacturer’s requirements regarding the minimum return temperature.
How does the TSV3B valve work, and why does it not need a balancing valve?
The TSV3B valve has an integrated thermostatic insert that blocks inlet “A” (from the heating system) while the return water temperature is below the opening temperature – during this time, only hot water from the boiler bypass flows through the pump. When the temperature reaches the opening threshold, the valve gradually mixes return water with bypass water while automatically limiting the flow through the bypass. This automatic flow control eliminates the need to install a separate balancing valve.
Where can the IBOMAT API pumping group be purchased?
Dambat does not sell directly. IBOMAT API 25/55 is available from our trade partners, heating and installation wholesalers, and authorized online distributors.
What does the valve opening temperature mean, and how does it differ from the +5°C control range?
These are two separate parameters describing the operation of the TSV3B thermostatic valve. The opening temperature (45°C, 50°C, or 55°C depending on the version) is the threshold at which the thermostatic insert begins opening the return-water inlet from the system. The +5°C control range means that the valve moves smoothly from fully closed to fully open over a range of 5°C above this temperature – for version 45, this is therefore a range from 45°C to approximately 50°C. When selecting an IBOMAT version, follow the boiler manufacturer’s requirements regarding the minimum return water temperature.
What are the warranty terms, and how can I contact service?
IBOMAT API 25/55 is covered by a 24-month (2-year) Dambat manufacturer’s warranty, calculated from the purchase date confirmed by the original proof of purchase.
