HTU Heat Transfer Unit Four Room

Adjustable outlet grilles version

So you have a fire in the lounge right and you ask why is it so hot in lounge and cold in the rest of the house, will that's easy the fire needs air to burn quite a lot of it, as the fire burns air it creates a vacuum which pulls air from all the rooms which have tiny gaps going outside where there is cold air the fire needs this air inside your home to keep burning, but this cold damp air can be displaced by taking warm air from the ceiling near the the flue of your fireplace, this is where heat transfer products come into play they are made up from a inlet grille, lengths of insulated ducting, a fan to move the air down the duct and a outlet diffuser in the rooms you wish were warmer. Heat transfer systems can be easily installed by the homeowner.



Use the excess capacity of your heating appliance to warm other rooms in your home.

How? With the HTU Heat transfer Unit!

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
