Smoke or Heat Alarms?

Zoomup
Mornin' All,

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?

    By contrast to Mike's example, when daughter had some repairs and repointing done, the builder put 6 pots on the 4 flues in the chimney - originally 2 on either side of semi-detached cottages. I could not convince her that there were only ever 4 hearths (which still exist).


    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. ?

    Log burners need Building Control permission and must be installed by a HEATAS installer.  In my experience the installer will arrange the Building Control;  CO detectors are mandatory and will be supplied by the installer.

    Same as new circuits, for example! ?

    a dual wall liner is always specified for enclosed fires

    Perhaps 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).

    Nobody seems to have answered my original question.


    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.

    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?

    The heat detector portion of the alarm will detect temperature rise. A smoke event with a temperature/heat rise will trigger alarm. Not sure how sensitive the threshold is but the principle is to reduce false alarms resulting from burnt toast etc just resulting in smoke!

    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!

    cheers Andy
