How? With the HTUK Heat transfer upgrade kit!

An average size lounge requires 2-6 kw of heating, yet heating appliances such as log burners* can generate 10-20kw.
That’s 5 times the amount of heat required for a lounge room. This leaves an excess of 8-14 kw of heat available to warm other rooms in your home.
Air trapped at ceiling level can reach temperatures in excess of 30°C. So why not Transfer that heat to where it’s needed
