Heating
technology
HeatBloC® K36 DN 20 (¾")
Field of application: Return flow temperature maintenance for solid fuel boilers, wood firing and stove heating systems
Recommended application range: up to 10 kW; 10 K up to 860 l/h
Opening temperature 45 °C (item no. 320353xx)
Opening temperature 60 °C (item no. 320363xx)
with 1" union nut for assembly on PAW distribution manifolds
with PAW mounting equipment, the HeatBloCs can be installed on wall brackets
Large ball valve handles,
easy handling, visible closing position
EnEV-compliant functional insulation
made of durable elastic EPP, complete insulation of valves and fittings, ventilation opening to cool the pump
the insulation for the distribution manifold is integrated in the heating circuit insulation
Free access to the pump head
by simply removing the front insulation shell
Check valve in the flow pipe
opposite to the pump, can be opened, 200 mm wc, spring-loaded, thus suited for horizontal and overhead installation
Thermal control valve with automatic bypass ensures that the boiler always keeps a minimum temperature (= opening temperature +/- 3 K) and prevents the boiler from contamination.
The K36 should always be used with a buffer tank, if not, a hydraulic separator is mandatory.
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.
When electronically controlled high-efficiency pumps are used, the type of control ΔP-c (DeltaP = constant) must be set.
The pump can be entirely isolated.
No draining necessary during servicing.
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.
