    I found this:

    https://assets.publishing.service.g.../attachment_data/file/697525/DBSCG_secure.pdf


    I'm a little confused on this one too. Can anyone please educate me.

    As of 2005 all new installations are required to be condensing boilers. In essence I believe these work by using the flue gas to heat the return flow prior to it reaching the heat exchanger, and so that the boiler can then modulate to a lower temperature, using less gas.
    • Is this not classed as 'Flue gas heat recovery'? (see 2.2)
    • If it isn't then whats the difference? (can't find an answer online!)
    • And if it is the same, is this point then not pointless?
    Thanks in advance

    Actually looked a bit further into this and what it actually means is that flue gas heat recovery must operate in HW mode. Google boiler-plus-final-policy-and-consultation

    Hey Martyn, cheers for that. It firms it up better.

    (page 32)

    Just out of interest, do many boiler manufacturers supply this functionality as standard and/or as an add on within condensing combi's? (i'm new to the industry and am currently studying!)

    Cheers

    Add on to flue of boiler.

    Alpha used to do it, Ideal did it with ideal logic esp code boilers, Atag do it on there IC economiser combi's which i would like for my own place.

    Basically they scavenge most of the remaining latent heat out of the condensate & essentially used that heat to pre-heat the incoming mains cold water to the combi.

    Makes sense & improves efficiency.

    Also if used in addition to weather comp & load compensation you will have got as efficient a boiler as is currently possible with technology available today.

    Examples below -

    Vaillant Heat Recovery Device recoFLUE PFGHRD | Ancillaries

    WORCESTER Ecoflo Flue Gas Heat Recovery Unit 7733600047 - New inc VAT | eBay

    Baxi & Potterton Multifit GasSaver - GS1 720056901

    Hope this helps,

    Andy

    Hideous and all massively expensive

    I agree, unless it comes integral with boiler, aka the ATAG IC economiser at the right price. (I cant get one direct from them as i don't install enough boilers & am willing to travel to see rep on his next trip down to the south west)..
    Then it makes sense.
    Otherwise as mentioned above by Harvest they are certainly fugly & you would not recoup the costs during the boiler life cycle.

    Hello All,

    Further to my previous messages on this subject Today I found some `very good news` from Baxi on Boiler Plus Regulations compliance:

    Hopefully this new development from Baxi will help Baxi Combi Boiler Installers to comply with the new `Boiler Plus` additional Controls Regulations - it is an `easy fit` Air temperature sensor which clips onto Baxi Combi Boiler Flue terminals with the wire runs through the Air intake duct into the Boiler:

    Boiler Plus and IFOS

    Here are the fitting instructions:

    http://trade.baxi.co.uk/documents/7687799_IFOS_Omnibus.pdf

    Product Information Sheets:

    http://trade.baxi.co.uk/documents/DEPT_242618_Baxi_IFOS_uSense_2ppA5Leaflet_rev4_OUTPUT.pdf

    Looking at the device picture in the Fitting Instructions I cannot imagine that it will be an expensive item [?].

    I am guessing that it will be `inexpensive` when compared to other options to comply with `Boiler Plus` such as Flue Gas Heat Recovery Units which can cost between about £400.00 and £1000.00 installed - ruling them out of most Installers preferred options.

    Even the `Smart Thermostat` option costs over £200.00 without `Smart Trv`s` added at probably £60.00 each to give a more complete `Smart Heating System Control`.

    I know that Smart Trv`s or even basic Trv`s are not included in the Boiler Plus Regulations [unless Radiators are being replaced] but if I were having a `Smart Thermostat` fitted I would have one that communicated with Smart Trv`s and also install the Trv`s.

    I can imagine that because it enables compliance with the Boiler Plus Regulations at a cost that I expect to be very reasonable [?] this product will give a massive boost to sales of Baxi Combi Boilers until other Boiler Manufacturers produce a similar product - unless Baxi`s patent is specific enough to prevent others copying the device ?

    Although it is an `Air Temperature Sensor for a Baxi Combi Boiler flue` I am guessing that their patent would not prevent other Combi Boiler Manufacturers from producing something slightly different in design ?

    I hope that Members will find this helpful although it would mean installing Baxi Combination Boilers to use this option to coply with the `Boiler Plus` Regulations.

    Regards,

    Chris

    If the customer or landlord refuses to have an additional controls fitted to meet the boiler plus regulations, were does the engineer stand?

    Can't install the boiler but I'm not loosing out so get them to sign a waver

    If they sign a wavier saying you have instructed them that new controls are required so the install meets the boiler plus regulations. But the landlord has refused is the engineer filling out the benchmark covered?

    Hello All,

    I hope that this is not breaking any Forum regulations as the Videos are informative and definitely relevant to `Boiler Plus` / this thread.

    Further to my previous messages on this thread about adhering to the new `Boiler Plus` regulations I thought that Members might be interested in these 2 Videos.

    One is about the Installation process for the Baxi `In Flue Outdoor Temperature Sensor` to a Baxi Combi Boiler here:



    The other is about the Installation process for the `Nest Learning Thermostat 3rd series` to the same Baxi Combi Boiler here:



    I hope that these Videos will be helpful to some Members.

    Regards,

    Chris
