Noob here. We live in a ex commission house, wayy too cold in winter and now decided to bite the bullet on central ducted heating.
Attached is a floor plan.
Been "sold" two very different quotes, one different from the other:
14kw TQ315 system, 6 outlets.
Says Company B is trying to oversell me a unit too large and is moving old stock.
20kw TQM520 system, 7 outlets.
Says if I install a smaller unit it would be very inefficient and I'd be basically back to square one and wasted my money.
To be honest he sounded more professional?
All bedroom windows face North and is by far the warmest parts of the house, the lounge room is frigid!!
