HeatBloC® K33R DN 25 (1")
Field of application: for thermally controlled radiant heating, for low-temperature heating used as a return flow temperature maintenance for solid fuel boilers, wood firing and stove heating systems
Recommended application range: up to 22.5 kW*; (radiant heating, Delta T = 10 K)
up to 45 kW* (return flow temperature maintenance, Delta T = 20 K), 10 / 20 K up to 1940 l/h

incl. 1½" union nut for the installation on a PAW modular distribution manifold.With PAW mounting equipment the heating circuit can be installed on wall brackets.
Large ball valve handles
easy handling, visible closing position
Thermal control valve (adjustable) prevents the flow temperature from rising above the set maximum temperature.The control valve also enables to adjust the maximum temperature appropriately to the installation (40 - 50 °C).
Bypass (adjustable on the front) increases the circulating water quantity and decreases the flow temperature when open.
Thermostat, adjustable in the range of 20 - 60 °C, when the adjusted temperature is exceeded a switch is activated and shuts off the pump.
EnEV-compliant functional insulation
made of durable elastic EPP, complete insulation of valves and fittings, ventilation opening to cool the pump
Free access to the pump head
by simply removing the front insulation shell
Check valve in the return pipe
can be opened, 200 mm wc, spring-loaded, thus suited for horizontal and overhead installation
Flow on the right = standard
Flow and return line can be changed on site, also for heating circuits with mixing valve
All water-carrying parts are made of brass
Full metal thermometers
can be pulled off, with immersion sleeve integrated in the ball valve
PAW heating pumps with high-efficiency (ECM) technology
fitted with 2 m cable, completely premounted, integrated in the insulation, pressure tested, with serial number, perfectly designed system, pump characteristics, EuP/ErP READY
Pump can be isolated,
so that it can be replaced without draining
Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. The following must be observed during installation and commissioning: - relevant local and national regulations - accident prevention regulations of the professional association - instructions and safety instructions mentioned in these instructions.
CAUTION Personal injury and damage to property! The product must only be used in heating circuits filled with heating water according to VDI 2035 / Ö-Norm H 5195-1. The product must not be used in domestic water applications.
NOTICE Material damage due to mineral oils! Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant properties get lost. We do not assume liability nor provide warranty for damage to property resulting from sealants damaged in this way. - It is imperative to avoid that the EPDM sealing elements of the unit get in contact with substances containing mineral oils. - Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
