Modular Manifolds

Plastic Manifold Solutions

Endorsed by leading Heat Pump manufacturers including Vaillant, Worcester Bosch & Danfoss our modular reinforced plastic manifolds remain ever popular. Modular design, self sealing, pressure tested and simple to install on site, these versatile modular manifolds are ideally suited for installation in Plant Rooms, utility rooms or outside in our modular GeoSTACK chamber.

Unlike inferior manifolds, our manifolds are resistant to corrosion and freezing - hence they will not crack.  To this end we are so confident in our modular manifolds we now offer a 3 year guarantee (must be installed strictly according to our instructions available at time of order).

Basic unit consists of:

  • Fill/Bleed Points (½”)
  • 40mm OD spigot (for connection to and from heat pump)
  • Mounting brackets
  • Isolation Valves (Flow & Return)
  • Branches complete with:
         Flowmeters (Variable) 8 to 32L/min
         Isolation valves
         Compression Couplers to suit 25mm, 32mm and 40mm collector pipes/probes


  • Thermometer with immersion sleeve, -20°C to + 40°C
  • Manometer (pressure gauge) with assembly valve, 0-6 bar
  • Auto Air Bleed Valve – An excellent way to ensure all air is removed from the collector pipe for very little cost!

Our manifolds can easily be housed in our Modular Chamber system.  Click here for more information.
