In the master assessment, navigate to Ventilation and Infiltration
Change the system, from natural ventilation (NV) to Intermittent Extract Ventilation (IE)
Add an Individual Intermittent Extract Fan - put it`s location as something like Bathroom
At this point, preview the MHEP Report - you should see an entry under Energy demand (kWh.a) for Fans and Pumps of 28 and the same value for fuel input.
Now navigate to Heating
Add a heating system
Use CMBB10: Typical Gas/LPG Combi Boiler with underfloor heating no storage
Stick with the default values
Again go and view the MHEP report - under Energy demand (kWh.a) Fans and Pumps is now blank and their Fuel input is 0.00
It seems adding the heating system overrides the fans. That said, if you navigate back to Ventilation and Infiltration the fan is still listed.
I tried populating the boiler info first but it had no effect. and i also tried not adding any fans and leaving it as natural ventilation, but it stills appeared to affect the calculations.
