@@warriorsofwarmth Thanks. ,I guess you don't know what a Supa tap washer is? I can probably bodge a new insert . But I'm trying to find a replacement first.
Righteous & happy :) Dewalt are shaking in their boots haha. Nice 👍 Yup, those knockoffs are really tempting 😓I was looking at a "Mirka" orbital sander, almost pulled the trigger on it but thought better not risk it. I feel like changing my mind now 😂
@@warriorsofwarmth why would it want it to modulate lower for heating surely the zero governor is in place for modulation and doesn’t it turn off automatically when it reaches temperature needed
Johno, my customer has 15mm primary flow and returns going to a vented hot water cylinder, could I use these if I wanted to changed to unvented, your fan Roo.
@@warriorsofwarmth Fair enough, but better results with ultrasonics & if so, less worry of problems if re used, so maybe cheaper and better in the end.
The whole point of putting down Beading or Quadrant is to replace Silicone. Why would you apply silicone again along with the Beading or Quadrant? You will still have the issue with black mould if you do this. Also, this has got to be one of the most annoying tunes ever
Great content👌 I'm having drama with a Betacom 3. Changed Diverter cartridge, but heating circuit is still half open on HW demand..I'm now thinking faulty Harness🤔(i.e. is it not fully moving to HW) or Dirt in the hydrobloc...I'm stumped😮
@@warriorsofwarmth all good there, recognises demand, fires up, heat goes around Plate and down the Flow....HW is warm at best, isolate the Flow= Instantly Hot.
Totally agree on the fuel poverty, i see some shocking poverty. Scares me how little safety net there is these days and the government paints a picture of people milking it....the reality is the polar opposite
Yeah seen that one, normally there's one on the gas valve itself, I went to a f28 fault two days ago and couldn't find the pressure point on the gas valve to see if it was opening up
@@warriorsofwarmthThank you for your answer. shall I switch the boiler off and check if that help? Or it won't change anything and I should call engineer? Anything else what I could try on my own?
I've seem more of these controllers in plant rooms than when on my fgas and air source heat pump course. Maybe the course I went on was bad😂. Seem similar controllers on pumps and pressurisation units. There's some free air source heat pump courses. As for fgas the best priced one I've seen is in potters bar. Ellis training.
@@warriorsofwarmth Johno what does the outcome of 1.89 litres refer to? Is it the capacity that the system needs in order to maintain a delta T of 20 C or something else, please forgive my ignorance, your fan Roo
@@warriorsofwarmth I can see they are all rated just like boilers, some listing the maximum flow rate and others listing the pipe size. Its relatively simple now, I need 1" pipe size and at least 45Kw with a max flow rate around 1.89 L/min, thanks man!
Johno, I need your help, how do I size a low loss header, there is no information on it anywhere. My customer has a gigantic house, 33 radiators, he put a massive pump on it to drive it to all rooms because his boiler on its own was too wussy to over come the resistance, well ok, but the consequence is that there is not enough delta t across the flow and return so the boiler modulates at a lower than optimal temperature. I phoned Vaillant, they suggested a low loss header to create a neutral point and provide hydrolic separation, ok thats fine, but how to size the thing? No one knows, all engineers I know are dunces, no one on the internet can help, you are our only hope, your fan Roo.
boiler is Vaillant light commercial, 44 Kw , S-pan, unvented cylinder and rads, lots of rads. Design temp delta t is 20 Celsius. It has an internal pump and an external more powerful pump that the householder installed in an attempt to overcome the resistance to the heating circuit. Vaillant propose hydrolic seperation i.e a low loss header. Thanks so much for taking the time Johno.
Johno, how do I size a low loss header. My customer has a light commercial Valiant boiler, 44 KW, it needs a low loss header as there is not enough differential temperature across the installation to make it ramp up to max temp. Any ideas, your fan Roo.
I have an apprentice, he's in his third year at Forth Valley College and he's always going on about emerging technology and telling me to do a heat pump installers course. I thought you might have some vids on whats involved. There are other ones on the internet but I canny trust them like i can trust you. If you have the time and inclination Johno, please make a heat pump installation vid, your fan Roo.
@@warriorsofwarmth Thx. I am aware of that from red to black in colour. But the burner now has a new part number. Are you saying there is no change with the burner, being the same old early failure job?
Wow, interesting video. I have been looking online on how to build a wine cooling room and meat curing room. Similar to this I guess. Cannot wait to watch once kids are in bed!
You are legend Johno helping the kid out. I gotta admit I prefer the older Baxi 600's and 800's, huge fan of a mechanical pressure gauge rather than the new digital ones, so much so that I would fit a Main or even a Platinum, but ok, It was easy to put them into service mode too, for commissioning. Can I suggest a video on Open Therm and how to wire? Would be interesting. thanks so much for all your effort in making the vids, your fan Roo.
