Great to see you at it again..The successes I have had on those boilers and hex have been by adding Fx2 or if you want to go Nuts use Scale-breaker Fx but you must only run it in the boiler..then flush it throughly out as The later has a tendancy to stay in the system..Which then means you need to flush all the system out and check the Ph balance and ensure that there is No residue left. Im sure with all the spares Knocking around you could get a spare Flow/Return pipes to get rid of the rubber hoses..which WILL break down with the majority of chemicals you will use (Even tho they say they Don't!) You really need to reverse the flow if you want to make any dent in the scale/debris hence the flush route. Or use a blanking plate for the OEM (Old pump without the impeller on if you don"t have one) and put an external small pump and do it that way, in any direction you want.. I often found the Pump impellor gains are blocked so worth a check. 1. Canoe filter, 2. Blocked pipes 3. Pump 4. Hex . Did you get your shopping done !!
@HeatingGeek
@HeatingGeek 5 лет назад
I agree. FX2 is the best of the best. I like scale breaker FX too.(Do Kamco even sell scale breaker anymore). I have a pump adaptor for these boilers. I have a power flush too. I just cant be assed to drag it too the loft!! If I have to I will though. I am worried about the rubber pipes because I left the chemicals in there so long. Out if sight out of mind!! :-)

Hi Heating Geek, your info regarding 22mm pipework being able to dissipate up to 23kw of heat is spot on, if you are testing the boiler in P1 and putting 37kw of heat into 22mm pipework I would expect some noise as you really need 28mm flow and return pipework to do that, another great video and I like your idea with the garden pressure sprayer
@HeatingGeek
@HeatingGeek 5 лет назад
Yeah 37 kw is a bit much but usually a new boiler won't make any noise. It will just get too hot and stop firing. My boiler copes very well but I defiantly have a noisy coil. If I leave the noisy coil it will block and then become really bad (clanging) all the time.

@proteus1
@proteus1 5 лет назад
I use the mears calculator and add 10% for heating pipework. I also incorporate bigger rads as most designers do small output rads and install standard 22mm pipe. You have to be careful as you can get system flow noise, but then the winters certainly get very cold and I like to have more output for theses snowy times. Most heating systems are boilers running flat out dial, right up high. My Mrs likes the noise from the rads as it helps her sleep. If you have a good insulated new house, your probably going to be ok.
@HeatingGeek
@HeatingGeek 5 лет назад
Weather comp all the way for me. Never ever touch the thing. Works a treat after the initial set up. It took me 2 winters to get the rads balanced correctly and now its great.

@oldbutstillcurious3615
@oldbutstillcurious3615 3 года назад
? Did you rely on the boiler's pressure relief valve to limit pressure ? Glad you had success. A lot of 'Bucket Pumps', by design, incorporate two disadvantages. Firstly, they are designed to pump very small volumes of liquid into a closed system that has been purged of air. Secondly, when pumping into a closed system very high pressures can result from very little pressure on the pumping handle. The scale on the pump's own pressure gauge designed for max 70 bar will be so cramped at '3 bar end' that needle movement could be almost nil at 3 bar (fix: use suitable gauge in parallel).

Got a question mate, CH is working fine but when the hot water is turned on so there’s demand boiler doesn’t switch to water it’s just cold like the cold tap. Boiler doesn’t even acknowledge demand for hot water. Is this a faulty diverter Valve or a sensor? Ecotec pro 28 mk1, engineers fiddled about but couldn’t fix it

If P1 was max heat input, it's a fair guess that's for DHW. From your table, when running for heating it may only be a 24kW boiler. Even my rads connected with 22mm pipe (pump speed 2) won't take 19kW - but it will if there's more CH load (which is why I don't run the pump at speed 3 as 2 is enough for the boiler when there's sufficient CH load. Now, with P1, are you trying to put 37kW through a load of TRVs ? TRVs don't open very much ! They're fine on microbore, not even 15mm !

Just watched part 4 ... how did things finally work out? I could not understand why you bothered to continue trying to get rid of the noise if the noise did not come when you ran the hot water for 15 minutes - as far as I understand things the boiler runs at its normal maximum while producing hot water for the taps - it usually runs at half power or less when heating radiators - and you can permanently throttle the boiler down when in central heating mode. 80 degrees C is excessive for radiators - dangerously hot for kids and old people. Having got as far as you did, I would imagine that draining the system and putting Fernox F1 in your system would have prevented things from getting worse - and possibly slowly improved things - without risking damaging some aspect of your boiler by leaving cleaning chemicals in too long ... Can a fully functioning noise free heat exchanger get worse than it is if it is running with clean water and Fernox F1?

No worries pal, appreciate you takin the time to get back to us. Got a Worcester 28cdi, that’s not holding pressure when off (will lose a little pressure upon initially filling up and turning on heating but its stable for the most part, however it runs down to 0.5 bar after a good few hours). I think it’s the prv coz the pipe out back is dripping, but I’ve noticed there’s a leak from within the boiler as well, thought it was something to do with the filling loop, but it’s definitely dripping from just above that. I know it’s impossible for you to tell me what’s wrong without inspection, but any ideas on what it could be? Just so if I do hire somewhere they don’t mug me off. Also is it normal for no steam/smoke to come out the flue bit?
@HeatingGeek

@@jnr4evr If the boiler is the RSF version then dripping from the pipe (15mm outside) shouldn't happen. The leak above the filing loop could be the diverter or vessel. Thats if its the RSF version.

Do not use leak sealer you could kill that heat engine in days. Why are you running that boiler at 80 plus deg's, your causing the particles in the water to stick to the internals, max 72 deg's and the noise will be gone anyway. Remember if the water can't pass through the heat exchanger fast enough then it will get to a critical temp ( think shower pump cavitation, air expands water won't move, starts to overheat) similar thing inside the boiler leads to noise, the thing is it's not always the heat exchanger that's part blocked, systems get dirty pumps get tired, filter get part blocked as rubber collects the scale. I had a Vaillant 415 making that noise that you think is the heat exchanger but it was while doing low burn rate test, by adjusting the fan speed in D something or other to a few percent higher speed the noise went, all it was, was the fan could not blow the products of combustion out of the flue due to the direction of the air movement outside, it needed just a bit more fan speed that is adjustable, the noise was the same noise though that we all know and had me fooled for a while.
