I am familiar with open fires that burn logs or coal. I am not so familiar with enclosed "log burners" or enclosed "multi-fuel stoves".
When using these is there a chance of some or fumes being created when using them that could trigger a smoke alarm, especially at the time of first lighting them?
I am about to plan a system for a holiday let cottage that has two log burners in two separate rooms. We don't want false alarms as the detectors will be interlinked.
Smoke or heat types?
More importantly is CO detection and ventilation - the ventilation is down to the installer of the stove and the flue but check the CO detection is not being left to you ?
The draw on a flue is best it if is both tall, and well insulated.
CO detectors are mandatory. If the flue is (partially) blocked over an open hearth, the fire will probably never get going; but with a stove, it could smoulder and give off CO.
Occasionally birds fall down our chimneys. The tell tale sign in the stove was debris so I took off the inspection hatch at the bottom of the flue. I found either a crow or a very sooty pigeon.
I have recently seen one where the neighbour's builders removed the chimney breast upstairs, without realising that the chimney pots for the two houses were front and rear rather than either side , (i.e.two chimneys, one per house, forming a wider but less intrusive column as a bulge in the party wall) and they left both pipes, including the one to next door's woodburner, open to the bedroom at floor level.
Luckily the bits of brick dropping into the grate alerted the side with the wood burner, and in the end the whole thing became more comic than tragic, and the chance was take to fit a proper flue liner as well as to reinstate half a chimney breast, but it could have been nasty, - if it misbehaves it may be wrong - there are some very funny set-ups out there.
When I got my wood burner (with pizza oven ) I could not get a quote from anybody without lining the flue at a cost of £2k. They seemed to think that chimneys blow rather than suck. 🙄
a dual wall liner is always specified for enclosed firesPerhaps for a new stand-alone flue, but when lining an existing chimney as simple single wall stainless steel liner can be used (at least was for mine, done my a HETAS engineer and as far as I remember was in accordance with the stove manufacturer's instructions).
The wood burners are o.k. and have been professionally installed. That is not the concern.
Used by people that are not used to log burners, which do the rooms require a smoke alarm or a heat alarm? I am not concerned with CO alarms. The alarms are to be interlinked. I don't want the whole house awaken at night if a log burner smokes.
I think that I agree with Mike that an optical detector/alarm may be best, but with a big billowing cloud of smoke even they may trigger.
Nobody seems to have answered my original question.
Oh dear, too much thread drift?
I wouldn't worry about the escape of smoke in normal service, so for me it's a smoke detector. That is smoke as in the contents of the dwelling are on fire.
Do a multi sensor combined heat and optical. They according to the manufacturers have an increased resistance to false alarms.
What is the purpose of the heat detection part of the combined alarm please? How will that prevent false alarms?
I have smoke alarm in living room with log burner and never had alarm triggered when accidentally opening fire door without ensuring flue damper was fully open. All alarms interlinked with heat alarm only in kitchen to avoid false alarms. Soldering fumes during plumbing work definitely set the smoke alarms off!
