• Check The Fit: 1 inch female threaded supply and return bars with 4 circuits at 50 mm centres, made for wet underfloor heating running 16 mm pipe
• Balance Every Room: A flow meter on each supply circuit reads 0 to 5 l/min, so you can see and set the flow to every loop instead of guessing why one room stays cold
• What You Get: Supply and return bars with 8 pipe connectors fitted, 2 mounting brackets, 4 bar clamps with rubber liners and fixing screws. Add ball valves, pipe and actuators
• Ready For Actuators: The return bar has an M30 x 1.5 thread under each blue cap, so M30 x 1.5 electric actuators screw straight on for room by room zone control
• Built To Last: Stainless steel bars rated to 10 bar and 90 °C for water systems, with an automatic air vent and a drain valve on each bar for filling, venting and draining

• Compact 4 Circuit Size: Each bar is about 29 cm long with 50 mm between ports, so it fits a slim cupboard or wall cavity and suits a single zone, extension or small floor area

Run water underfloor heating in up to four rooms or zones from one compact pair of stainless steel bars. This LavaTherm 4 port manifold has a supply bar with flow meters and a return bar ready for actuators, so you can balance each loop and control each room separately.

Specifications: stainless steel bars; 1 inch female threaded ends; 4 circuits at 50 mm centres; flow meters 0 to 5 l/min on the supply bar; M30 x 1.5 actuator thread on the return bar; automatic air vent and drain valve on each bar; maximum working pressure 10 bar; maximum working temperature 90 °C; medium water.

Compatibility: for wet underfloor heating with 16 mm pipe, connected through 1 inch ball valves to your pump and mixing set or heat source. The M30 x 1.5 return ports take M30 x 1.5 electric actuators for zone control with room thermostats.

In the box: supply bar with 4 flow meters, return bar with 4 actuator caps, an automatic air vent and drain valve on each bar, 8 compression pipe connectors fitted, 2 mounting brackets, 4 bar clamps with rubber liners and fixing screws. Ball valves, pump, mixing valve, pipe and actuators are sold separately.

Why LavaTherm: the flow meters show the flow on every circuit, so balancing is quicker than trial and error. Each bar vents its own air and drains through its own valve, which keeps first fill and later maintenance simple. Stainless steel bars resist corrosion and keep their finish in a plant room or cupboard.
