I bleed mine on a night using an airline, (an old trick from working down the docks, we used to supply ships with fresh water but in winter after supplying we used to blow the lines clear of water with compressed air)
Vent/flue not done yet, worked with van doors open not ideal but let us work a full day to try it out.
IMO the next hot system i will buy will be a diesel fed system, ionics type. Hot water is great too use, hot pipes etc, my cheap heater will last a while and will more than pay for itself but for a more permanent solution I will have too spend some good money!!
Will review the cheapo after some more use!
