Hi everyone.

does anyone happen to know when 2 speed heaters came in and are they just a straight swop for the single speed or what do you need to alter?

Also, does anyone happen to have one for sale?

Didn’t come in until very late - MPi only from the factory.

They are easy to retrofit, but hose size, hose connection locations and vent pipe size could all differ from what you have.

Twin speed heater conversion has done many times before-

If you haven't already done so it's worth checking the hoses & vents to correct any big gaps.

(The original MPI resistor pack is NLA but the Somerford website show stock, they're certainly not cheap!

You just need a suitable resistor or speed controller.

As above single speed heaters can easily be swapped to multiple speeds. I used an MG resistor as in this thread. https://www.theminif...eater-resistor/
