The Termojet TJ-MU pump mixing unit is installed in front of the underfloor heating manifold. The mixing unit lowers the temperature of the heating medium from a boiler or heat pump to 20–60 °C and creates a separate circulation circuit. 3 models, price from UAH 5,959. The circulation pump is not included.
Underfloor heating mixing unit up to 120 m² Termojet TJ-MU-10B
The pump-mixing unit Termojet TJ-MU-10B is a compact, ready-to-install solution for connecting an underfloor heating circuit to a boiler or heat pump.
Underfloor heating mixing unit up to 150 m² Termojet TJ-MU-25
The Termojet TJ-MU-25 pump-mixing unit is a ready-to-use hydraulic assembly for reducing the heat-transfer fluid temperature from a boiler or heat pump to the safe level of 20–60°C required for an underfloor heating system.
Underfloor heating mixing unit up to 200 m² Termojet TJ-MU-40A
The Termojet TJ-MU-40А pump-mixing unit is a powerful ready-made solution for connecting large or multi-zone underfloor heating systems to a boiler or heat pump.

Mixing unit FAQ
What is an underfloor heating mixing unit for?+
The unit lowers the temperature of the heating medium from a boiler or heat pump to the level required for underfloor heating and creates a separate circulation circuit.
Is the pump included?+
No, the circulation pump is not included. You can choose one in the «Pumps» category.
Which model should I choose?+
It depends on the underfloor heating area: TJ-MU-10B — up to 120 m² (Kvs 2.5 m³/h), TJ-MU-25 — up to 150 m² (Kvs 3 m³/h), TJ-MU-40А — up to 200 m² (Kvs 3.5 m³/h).
What does the Kvs of a unit mean?+
Kvs is the flow coefficient of the mixing valve: the flow rate in m³/h at a pressure drop of 1 bar. The higher the Kvs, the larger the underfloor heating area the unit can serve.
How is a mixing unit different from an underfloor heating mixing valve?+
It is the same equipment. The unit mixes hot heating medium from the boiler with the cooled return flow to supply water at the required temperature to the underfloor heating circuit.
Do you deliver across Ukraine?+
Yes. Termojet has been manufacturing its own products since 2002, and we deliver throughout Ukraine. Details are on the «Delivery and payment» page.
