I have recently purchased an I -heat and i thought I would share my experience as there a bugger all reviews out there.
After researching many options for central heating I took a leap and went for the iHeat. To give some context we are heating a 140sqm 1930's weather board home with insulation in the walls, ceilings and floors. Windows are single glazed and 70% of them have thermally lined curtains.
Key reasons for choosing
Hope that is useful to someone.
do you have bottled gas or connected to the street?
so might not be anywhere near as good on bottled.
You will need to crunch some numbers. My understanding is the cost per kwh is more expensive but you save on lines charges
