DIY install of a DG Aste: we are thrilled. Kitchen open to dining room - volume 66 cu, old house. Outside temp of 4 deg C both rooms up to 22 deg C, average one 1 kg wood log per hour, lever set to 2/3, central heating off. Stove draws well - no blow back or smell of smoke. Large glass - great. Lever control quickly adjusts, from a few flickering flames to full roar and no need for glove to adjust. Logs burn at a rate which is slower (about 1/3) and the heat output is much higher (about x 3) than open fire in previous house. Heat permeates to bedroom above. Before work I light the stove, have a shower, & down to breakfast in a warm room before leaving at 0600. 2 hrs later my wife is up & just needs to put a log on; perfect. Log length of 8-9 inches recommended: logs can be placed aligned front to rear - do not roll against the glass and soot it up. Sweep flue pipe via fire easy. Stovefitters Manual comprehensive and helpful. Delivery from Stovefitters prompt. Emails answered within 48 hours. Support good. All enabled a DIY installation to be undertaken without difficulty. A 6" flue pipe (9m) installed by pulling up from the chimney pot with a rope: remarkably easily. Downwards would have been tricky. Liner not insulated. Stove stepped out into the room by 10 cm using 2x 30 degree elbows to maximise heat output to room. We now know that stoves need drier wood than an open fire to avoid glass smoking up and for the wood to burn well. Estimated heat radiation using the back of a hand as a thermometer is 36 % front glass, 20 % sides, 16 % top, 8% rear, 4 % base & at best guess, 16 % up the chimney. Ash tray 3/4 full after approx 80 hours of burning. My wife initially cautious about me doing a DIY install; we got quotes from 3 local fitters and looked at different review sites. DIY installation: we both agree the right decision. Aste rather than Ivar? Traditional look and the internal mechanics of the two are identical. Thank you Julian, Arran, Emma and Reg.
