Love this video. This fella showing this test is bang on. In the real world, if you can’t achieve the desired flow rate to carry out the test, you have to use your noggin’ a little more and that is where experience comes in. To the apprentices watching, listen to the old fart that is trying to teach you. We may not be ‘cool’ but the odd few of us know a thing or two. Top effort. 👍

Very good video , sorry if this question seems silly, On a boiler with a 3 speed pump, Does the speed setting of the pump have any bearing on the heat transfer temperature from the main heat exchanger to the domestic hot water at the plate heat exchanger or will there be no difference what ever the pump speed is

@lestc8579

3 жыл бұрын

Yes it does..you stick it on 1 on a 3 speed and it will cause you probs

Good tip that. 👍🏽

So to recap first test between hot and cold and check for 35⁰C temperature rise and stable reading. Then test between hot water outlet and pipe between pump and main heat exchanger, there were 20⁰C difference and there should be zero or close to zero. But when it finally became 0 on third attempt, is it because you cleaned the plate or you put the clamps somewhere else? Thanks advance!

Great video and just one quick question: What I understand is that the heat lost in the primary circuit between flow and return should be gained by hot water side.? Lets say the primary flow was 75c then return 40c. Then the hot water would be 40c? How is that. Bec i thought the hot water temp = cold water in temp + (diff between primary flow and return) So lets say cold water is 8 c and the pFlow 75 preturn 50c( meaning a 25c lost to heat hot water) then hot water is 8c+25= 33c Sorry if that looks naive

Where did you get the 35c from?

I'm assuming the tests in this video apply to all makes/models of Combi Boiler, not just Ideals? Is it also correct that you can check the temperature of the primary circuit flow and return in and out of the PHEX and that a temperature difference of more than 20 degrees indicates a blocked PHEX? I'm sure I've read this somewhere but can't recall where.

No this is just the logic only due to its design, other designs may vary slightly in temperature depending on where you put your temp clamps.

Not sure of its a separate issue but a) lack of hot water via taps . Mostly goes cold ..... kitchen tap (,been fine 3+ years now is the only tap mainly that don't cause boiper to ignite . 9ccasionally it'll stop getting up upstairs bath over head shower (mixer.

Im relatively new to boilers and I was inspecting a hot water issue today with a eco Tec pro 28 combi boiler. Visually I could see major scale at the cold inlet to the plate heat exchanger. In addition the hot water appeared to be running well until suddenly it stopped coming out the faucet, then continued after about 12 seconds. I'm pretty sure it was the plate but does anyone have any other ideas? Wasn't isolation valves as none existed on the pipework....note: the water did reach requested temperature prior to cutting out. My guess is it's a sedement blockage, but any other suggestions are welcomed. Thanks ppl.

I left a well paid job fitting meters for that as well. Awful company

Double check that the water inlet isolation valve hasn't been turned down. The hot water flow usually stays about the same on a blocked plate. As it usually the flow circuit from the main heat exchanger which gets blocked . Check your mains water tap is open fully and follow the cold water feed from the boiler back. Sometimes there's an isolation valve or something similar fitted. This could also reduce the flow to all hot water outlets.

At the very end I found the part number ID to be very helpful , sick of wasting time with wrong parts.

Can anyone help me diagnose my issue - basically turn tap on, might get a little bit of hot for a few seconds (in the PHE?) then cold - then takes ages, a minute maybe of completely cold water, then the hot starts to come through. Once flowing it's fine, stays how, flow rate no problem, runs all day. I swapped the DHW spinner last year, when you turn on a tap the sensor lights up solid instantly, boiler seems to start. I removed the diverter valve and stripped it, cleaned it in ultrasonic cleaner, put in new seals, rebuilt it with lashings of silicone grease Actuator works fine, tap on, tap off it moves in and out and the plunger pushes in no problem in the valve (did before cleaning anyway) - heating outlet not getting hot when waiting for water PHE off and cleaned with drain cleaner and in ultrasonic, just a bit of rusty crap coming out, no sludge in there and it's a soft water area so no limescale.... Water flows though both sides well from hose pipe. Again once running hot water is more than adequate, heating works fine Waiting for a plumber friend to come check gas pressures etc as very rarely do get an ignition failure - can't see it being that as it locks out after 3 failed starts and it's very rare (maybe 1 this year)??? Boiler did have a gas valve about half it's life ago as it had turned into a vuvuzela.... I'm stumped!! Help lol 😄

Great video yet again from ideal man only thing I would add is he should have tested the cold water flow rate as it could be the cold feed could have only been 10 litres per minute so putting a 35kw boiler in and thinking you would achieve 16 litres , always check water pressure and flow rates on a cold tap before you install a boiler .

@kevincranfield5235

3 жыл бұрын

I never thought I would achieve 16 litres per minute when I installed my boiler, I put a larger boiler in knowing I would infact get a better delta t, temperature rise because I had a lower water flow rate, I just forgot what my flow rate was when I was making the video and then realised I could not get the 16, it was the reason you saw in the video why I put in.a 35kw so I could get a temp diff way over 35 degrees.
