Broseley Help Us


At last on Pig Row we have some form of sanity again as Broseley come through and send us the following email which makes everything crystal clear (this information was emailed to us on the 20th December 2011, and was correct at the time of publication, please check with Broseley technical direct).
Please find below a table that gives guide lines as to the operation of the Thermo Suprema 18.5 cooker (along with our comments in red, following the guidelines in the manual).

The test report is from the cooker in our lab. It sets out a sequence that will heat the oven to over 200 degrees in around 1 hour (when we did it we had it set to oven and it took us 90 minutes to get to 130 degrees, and a lot of wood).

As per the chart a large load of fuel means a full firebox of wood running front to back and pushed towards the back of the burn box. For best results use smaller wood logs so that they ignite quicker and ensure a good bed of embers once they burn (we got this right!)

For the initial heat requirement both primary and secondary air sliders should be open and the thermostat set to 5 (we were told by the rep to only use the sliders and to close down the thermostat).

ONCE THE WATER TEMPERATURE REACHES 60° THE DIAL SHOULD BE CHANGED TO THE OVEN SIDE (this would have been really handy to know from the start and may answer why the boiler got too hot).

PLEASE NOTE ONLY DRY WELL SEASONED WOOD WILL GET THE OVEN TO ITS OPTIMUM TEMPERATURE (we always use well seasoned wood from Certainly Wood).

We will now try this sequence and let you all know in the next few days if this solves the pressure drop on the boiler. Thanks for the help Broseley, can you please put this information in your manual or train your reps to know this.


A qualified engineer recommended by Broseley eventually identified problems with the pump and lack of sealant in the system. SCWS need water tight pipes unlike an unvented system. The system has run well since then.
