    Honeywell API output 'lagging'... since the clocks went back?

    Does anyone else here use Honeywell's API to access their thermostat? I am seeing what appears to be a bug in their system leading to results which are an hour behind... And I can't help but feel it is related to the clocks having gone back an hour on 31st Oct but the US not due to move until...

    Online boiler providers - good option or spawn of the devil?

    I am currently weighing up replacement boiler options, not just regarding the choice of boiler itself but who/how to get the installation work done too. I happened to stumble across the likes of Heatable and Boxt (are there others in this market too?) who seem to be offering what they describe...

    Safety/reliability of gas isolation valves

    We want to retire a gas hob (now have induction in a new kitchen in a different room) and so want to get the branch pipe that supplies it capped off. However, we're not quite ready to get that done and so ideally would like to remove the hob and - if safe to do so - have it temporarily isolated...

    Replacement Honeywell terminal blocks (moved)

    This is a long shot... almost worth not typing but you never know! I've just bought a Honeywell T6 smart thermostat - sold as 'untested; spares or repair' and I can see why! The receiver doesn't have any terminal blocks to wire to as seen (or not!) below: I have managed to lash up some...

    Seeking a boiler with a low(er) minimum modulation rate

    We've currently got an Icos HE15 heat only boiler on an sealed system (and UVC with 19kW coil) and whilst it works well enough it is 13 years old now and so I've been thinking about what I might eventually replace it with when/before the time comes. The system is well balanced with an average...

    Accuracy of Nest TPI control?

    For many years I've been using a Honeywell CM927 thermostat that has managed rock-solid control of room/house temperatures. You can see the stability in the graph below - noting in particular the grey line representing the temperature in the room with the stat and the red line showing the...

    Nest Thermostat Overreading

    I've got a Nest 3rd Gen thermostat and have found it to be overreading by ~2C. Whilst I don't have any calibrated thermometers to check against I do have a variety (I didn't realise before now that I must have an unhealthy obsession with them!) which all agree to within 0.5C of each other so it...

    Automatic bypass valve passing?

    Our CH system has an automatic bypass valve fitted but it has always been closed off (or at least set on the max value of '7') as we have three radiators without TRVs hence it was assumed it is not needed. I discovered today, however, that the bypass valve appears to be passing. Specifically...

    Pump Overrun on Intergas OV18

    I've currently got an Ideal Icos HE18 heat-only boiler and, seemingly somewhat surprisingly given what I've read about it, has never let me down. However, at 15 years old I know it is only a matter of time before it reaches the end of its life and so I thought I'd start looking at candidate...

    Adjusting Siamp Storm flush volume?

    We've got three identical toilets here all with Siamp Storm 33A flush valves... One of the toilets appears recently to be providing a relatively low flush volume. The cistern fill height is the same as the others (6L), it's just when you press the button the valve lifts and the flush starts...

    Screws for resilient bars?

    I am about to fit a new ceiling using resilient bars and am wondering what screws I should be using to affix the boards to the bars? Is this where the difference between coarse and fine threaded plasterboard comes into play? If so, my gut feeling is that it'd be the fine threaded screws that are...

    Likely cause of boiler transformer failure?

    I have an Ideal Icos HE15 heat-only boiler which, judging by the archives here, I understand to be the unwanted child of the boiler world. That said, this one is 12 years old now and has given sterling performance for the 9 years since we adopted it. Until now that is. Today the house was cold...

    Compression fitting tightness on plastic pipe?

    When using compression fittings on copper pipe I've always hand-tightened plus half a turn. I think it was just a rule of thumb taught to me by my Dad. I was wondering, however, how tight I should make a compression fitting to plastic pipe - more/less/same? My intuition is saying it should be...

    Removing UPVC window

    I want to remove a UPVC window and having hacked off one side of plaster on the inside I was expecting to find cleats similar to these securing the window to the internal wall leaf: https://www.wickes.co.uk/Wickes-uPVC-Window-Frame-Fixing-Cleats-Pack-of-10/p/180130 But I didn't see anything...

    Internet-Enabled Cat Feeder

    Thought I'd help get the new sub-forum off the ground and mention my Internet-enabled cat feeder: It has been in regular use for over 5 years now without a single hitch and whilst reliability was important I never thought I'd get this far without any issues! Further design/development...

    Shared downpipe and ownership of sewer

    [I first posted this in the plumbing section but it probably sits better here] We live in semi-detached house with an inspection chamber for the rainwater sewer at the end of the garden with two inputs and one output. The two inputs are fed by underground pipes from the rear of our house...

    Shared downpipe and ownership of sewer

    We live in semi-detached house with an inspection chamber for the rainwater sewer at the end of the garden with two inputs and one output. The two inputs are fed by underground pipes from the rear of our house; the first fed by the downpipe from the garage roof and the second fed by the...

    Solvent cement filler for a strap-on boss

    I thought I'd throw this question out to those in the know... I intend to fit a strap boss to an internal soil pipe. The pipe is made by Osma so I figured it makes sense to use their strap boss to ensure a good fit. However, I have noticed in the Osma design and installation guide (pg 110)...

    Recommended screws for skew-nailing deck boards?

    I am currently planning the construction of a deck and have opted to use Simpson DBT1Z 'hidden' deck board ties to affix the boards. As you can see from the following graphic these require nailing in to the edge of a board (for which galvanised nails are provided) and then butting up and...

    Viessmann Vitodens 100-W Compact boiler and pump overrun

    I am currently the lucky owner of an Ideal Icos connected to a sealed S-plan system with an unvented HW cylinder. Whilst it has never really given us any trouble I am acutely aware that by all accounts I am actually playing a slow-motion game of Russian roulette and it is only a matter of time...
