    Rate of heating in a living room?

    WBosch have informed me that the minimum central heating rated output for my boiler is 7.2 kW. The other rads which I had on on the other level, are: Double panel radiator: 42" x 23" (107 cm x 58 cm) Single panel radiator: 47" x 28" (119 cm x 71 cm) Acova column rad: (60 cm x 62 cm) 3540BTU...

    Rate of heating in a living room?

    I'll maybe set the boiler to 60 C, switch off the other rads on the other level. Leave on, as originally, only the rads on the same level as the main rad and determine with certainty if cycling is occurring.

    Rate of heating in a living room?

    The other few rads are still open when I took the last measurements. I could easily take these again with these other few rads closed off again. I need to double check that the boiler was running continuously at 75 C with both valves open in order to be 100% sure , but certainly on the various...

    Rate of heating in a living room?

    When the boiler was switching on/off every 3 minutes, there were only the 4 rads on in total. After getting the connections to the main rad switched around, I also switched on some other rads on the other level. There is no "stat" that I am aware of. I'm not entirely sure what this is. There is...

    Rate of heating in a living room?

    From what I had interpreted from Youtube clips was that the circuit would be on one floor. A different floor would be a different circuit. I could well be wrong, but that's what I had taken from it. So when I balanced the rads, I balanced the rads on the floor of the rad in question. Yes, I've...

    Rate of heating in a living room?

    Can I just check, so open lockshield fully on the rad in question only, turn boiler up to 70/75 C, then re-balance other rads if required so that their lockshields still only open as little as possible whilst still allowing flow? Once this is done, then turn set boiler temp down to 60 C? The...

    Rate of heating in a living room?

    If you mean before now, it's because it's not something I'd ever given any thought to. I had heard the term before, but didn't really know what it was exactly until I looked it up on Youtube. So, the other rads on that floor are: a) the other vertical rad has 1192 watts (4071 BTU) at delta 50C...

    Rate of heating in a living room?

    An update: I now have the flow pipe connected into the TRV and the return to the lockshield. I've ascertained the order in which rads heat up on that floor. After doing, I've turned all the TRVs up full and all the lockshields closed off. Then, with the rads allowed to cool, starting with the...

    Rate of heating in a living room?

    Does this give any insight into whether a diverter would be beneficial, or best to consider this after the rad feed/supply are switched and 15C drops are added to the rads?

    Rate of heating in a living room?

    It was set to 60C though in reality it fluctuated up and down between, what was it, 55C and 67C ish as it cycled

    Rate of heating in a living room?

    It's 3 bars per column. It appeared to go up the central bar directly above the feed. Then go across the top directly across all at the top, then cascade down heating all at same time. Hopefully, that sounds ok, if not I can repeat and see if I can determine any further detail. I didn't notice...

    Rate of heating in a living room?

    I've carried out the test and it heats up along the flow side, then across all bars at the top, then from the top down across them all.

    Rate of heating in a living room?

    I'm doing that ASAP. For what it's worth, I've asked the radiator manufacturer and they state that the rad does not require a diverter (or have an in-built one).

    I've just seen a picture of TBOE at the link below, and yes that is ugly. https://www.stovefitterswarehouse.co.uk/pages/heat-sink-radiator

    Rate of heating in a living room?

    Thanks guys, your input is very appreciated. As I mentioned earlier the flow for this rad is definitely going into the lockshield, and ideally it should be going into the TRV (which is not bi-directional). So I'll get that sorted and then I'll get the rads balanced so they have 15 C drops...

    Rate of heating in a living room?

    I don't want to appear that I'm not listening. Ultimately, I have no plumbing background. I'm listening to two different opinions here and, yes I can get the window sorted, but aside from that I don't know if I need a different brand of radiator or if it's just a matter of getting the system...

    Rate of heating in a living room?

    Presumably the deltaT figure which you refer to is data which a radiator manufacturer can easily provide if I were to ask for this figure from a different manufacturer before purchase (and hoping that the figure which they provide isn't an over optimistic figure). What sort of figure would I be...

    Rate of heating in a living room?

    The times above are in minutes, so it's off for ~3 minutes or so before starting up again.

    Rate of heating in a living room?

    So you're not seeing anything from the figures to indicate that it's a problem specific to the boiler. It's more likely an issue with the radiator and the window?
