All of the Midi Heater components are manufactured within the UK & Europe, we have used high quality components which ensure longevity and safe operation.

We are able to manufacture custom heater systems with a minimum order quantity of 10pcs or more, we have at our disposal 3D Scanning, 3D Printing, 3D Design and Fabrication equipment allowing us to produce high quality and cost effective solutions for your HVAC requirements.



 I.            This heater is not available without the water valve.

II.            The water valve is not a bypass design, when in the OFF position no water will flow back to the engine, therefore this heater is unsuitable for use on a vehicle which also uses the heater circuit as the engines thermostat bypass circuit. If your engine has no thermostat bypass circuit you have two options: (A) Retrofit a thermostat bypass water circuit though not always possible, or (B) clamp the valve on the heater fully open so it cannot move and then install or use the original heater bypass valve.

III.            This is not a stand-alone heater system; you will need to provide a hot water supply by plumbing your heater to your vehicles engine cooling system or a hot water heater manufactured by companies such as Eberspacher, Webasto or Mikuni.

IV.            This is not a complete kit. We would recommend the following additional items: 4 Position Fan Switch, Rotary Heater Control Knob, Bowden Cable, Water Hose, Air Ducting, Air Vents etc. We can supply all parts mentioned above and more. We do not offer packaged kits as everybody’s requirements are different and there are never two installations the same!

V.            Please make sure that no foreign matter can be ingested into the fan, this is the quickest way to destroy blower motors and could potentially cause a fire. For example, this is particular important if the heater unit is installed onto or close to the floor of the vehicle. A filtered cover may be required to protect the blower and ensure long operation life.

VI.            Don’t be afraid to get in touch with any questions no matter how trivial!
