Pump group Termojet Boiler without mixer 1" FT in thermal insulation without pump PG-67(150)

Pump group NG-67 — a specialised Termojet unit for convenient and quick connection of an indirect DHW water heater to the heating system. The direct group without a mixer delivers coolant to the boiler coil at the full boiler temperature, while the high flow capacity Kvs 10.2 m³/h ensures minimum hydraulic resistance and fast heating of the water heater.

The design takes into account the specifics of boiler connection: the built-in check valve prevents parasitic circulation through the coil when the boiler is not heating DHW; the valves with thermometers 0–120 °C on the supply and return lines allow monitoring of the temperature differential and disconnection of the boiler circuit for maintenance without draining the system. The thermal insulation jacket reduces heat losses from the unit in the boiler room.

Applications: connecting indirect DHW water heaters to manifold boiler rooms in private homes, offices, and commercial properties. The group mounts on Termojet distribution manifolds: for standard boiler rooms the manifold K22VN.125 2+1 top+bottom with a standard centre distance of 125 mm is suitable; for series 150 manifolds, the group connects via the adapter KP200/300. Hydraulic independence of the boiler circuit from the heating circuit is provided by the hydraulic separator GS-26 1¼″.

Advantages of NG-67 from Termojet:

• high flow capacity Kvs 10.2 m³/h — fast heating of large water heaters;
• fully assembled unit: valves, thermometers, check valve, and jacket included;
• union nuts on supply and return — installation and removal without welding;
• Ukrainian production, affordable price, and official manufacturer's warranty.

Technical parameters: maximum capacity 10 kW at ΔT=10 °C and 20 kW at ΔT=20 °C, Kvs 10.2 m³/h, connection to manifold and circuit — 1″ female thread, working pressure up to 6 bar, height 286 mm, width 264 mm, volume 0,32 l. Circulation pump installation length — 130 mm; pump not included, we recommend the Termojet APE 25-60 circulation pump (130 mm).

Note: connection to a manifold with a beam spacing of 300 mm is made via the adapter KP200/300. Other pump groups — in the Termojet pump groups catalogue.

The unit is also compatible with water heater heating from a heat pump — for more on low-temperature solutions see the Termojet heat pumps catalogue.

Frequently Asked Questions

How is NG-67 different from other pump groups?
This is a specialised water heater group: compact (height 286 mm), without a mixer, with increased Kvs 10.2 m³/h for low resistance on the coil. Designed for quick and convenient connection of an indirect water heater.

Is the group suitable for any water heater?
Yes, for any indirect water heater with a 1″ threaded DHW connection. The heating capacity depends on the water heater volume and coil diameter, but Kvs 10.2 m³/h covers the needs of most models up to 300 l.
