Listing controls
Boiler modules HEAT BLOC (PAW system) are used for the hydraulic connection of a heating circuit to the boiler - they ensure the circulation of heating water via a pump and, where necessary, temperature control by means of a 3-way mixing valve. They are supplied in DN 25 and DN 32 sizes, in both unmixed and mixed (type K34, 3-way valve) versions.
HEAT BLOC K31 modules are unmixed and connect directly to a common manifold; they are fitted with Grundfos (ALPHA2.1, UPM3 Auto) or DAB (EVOSTA2, EVOSTA3, EVOPLUS) circulation pumps according to the required flow rate and head of the circuit. Modules without a pump are intended for installers who add the pump separately.
Frequently Asked Questions
- What is the difference between the K31 and K34 module? K31 is an unmixed module for direct circuit connection, K34 contains a 3-way mixing valve for controlling the temperature of the heating water in the circuit.
- How do I choose a suitable circulation pump? According to the required flow rate and head of the specific heating circuit - the modules are compatible with both Grundfos and DAB pumps in various power ranges.
- Is a separate manifold required? Yes, HEAT BLOC modules are mounted on a common PAW.HEAT BLOC V23 manifold, onto which several modules can be fitted side by side.
- Can the module be ordered without a pump? Yes, versions without a pump (or without an actuator for the mixed module) are also available for installers who assemble the components separately.
