Hi, I am making my garage into a double one/workshop. It will take the door opening to a span of approx 4500mm. This will take the weight of the pitched roof/conc tiles etc. The drawing says toe beam over, not sure what this is! Is it made, or formed on site or bought to fit?! Whatever lintel...

You can buy a flexible duct quite cheaply. Provide it will not get damaged you could run it into the garage to an outer wall and connect to a grill. But agree it must go outside!! Dunc

Hi, Thanks for the reply i will have a closer look. Its definitely concrete on the inside. Could be version one tho'..... Ta, Dunc

Hi, I have just put in two new radiators and replaced all the on/off valves with TRV's. When I refilled the system and fired up the boiler was very noisy, banging etc. This diminished and now the boiler cuts in and out every minutes or so and then turns off after 10seconds. I guess there is an...
