00:00:02.600 my name's Allen haff in today's video 00:00:05.48000:00:05.490 we're going to talk about no hot water 00:00:07.70000:00:07.710 on a bee's Minh mitad ins 100 this 00:00:11.57000:00:11.580 boiler is a thirty five kilowatt boiler 00:00:14.14000:00:14.150 so we're going to go through some of the 00:00:16.22000:00:16.230 basic things to check and also this 00:00:20.12000:00:20.130 boiler the water is fluctuating hot and 00:00:23.42000:00:23.430 cold goes up to temperature so I'll show 00:00:26.02900:00:26.039 you that and then I'll show you how to 00:00:28.00900:00:28.019 repair it as well so first of all that's 00:00:30.74000:00:30.750 all I couldn't look at the boiler this 00:00:33.65000:00:33.660 is the Vitter dooms 100 W B 1 C and it's 00:00:39.70900:00:39.719 a thirty five kilowatt boiler we would 00:00:42.92000:00:42.930 expect to get around 14 litres a minute 00:00:45.79900:00:45.809 from this at 35 degree raise I haven't 00:00:51.26000:00:51.270 turned the power on yet on this but we 00:00:53.66000:00:53.670 would check obviously we checked the 00:00:55.72900:00:55.739 power was on that's the hot water 00:01:00.93900:01:00.949 selector and we would turn that up make 00:01:03.97900:01:03.989 sure that's up on to full and then we'll 00:01:07.55000:01:07.560 turn the boiler on 00:01:13.25000:01:13.260 and then what I'm gonna do before we 00:01:16.68000:01:16.690 even take the case often before we look 00:01:19.11000:01:19.120 inside the boiler 00:01:20.31000:01:20.320 we'll go run the hot water tap and we'll 00:01:24.00000:01:24.010 check the flow rate just to make sure 00:01:26.94000:01:26.950 it's not running too quick through the 00:01:30.39000:01:30.400 boiler so we'll check that now the 00:01:34.77000:01:34.780 importance of checking this is if you've 00:01:36.99000:01:37.000 got too much flow going through the 00:01:38.58000:01:38.590 boiler then the water will be will be 00:01:42.36000:01:42.370 cooler it can only rise the temperature 00:01:44.34000:01:44.350 it's quite 35 degrees and that's at 14 00:01:48.63000:01:48.640 liters per minute so we'll see that 00:01:53.99900:01:54.009 clearly it is about 14 minute so all you 00:01:59.43000:01:59.440 got running now and then you're gonna 00:02:00.96000:02:00.970 look inside the body temperature so I 00:02:05.40000:02:05.410 turn the hot water on now it's just 00:02:08.96900:02:08.979 going up to full we would expect this 00:02:12.19900:02:12.209 normally to settle around 62 to maybe 00:02:18.35000:02:18.360 sixty seven ish maybe about 65 degrees 00:02:22.14000:02:22.150 would normally expect this to settle up 00:02:25.35000:02:25.360 if it goes above that then we would 00:02:30.42000:02:30.430 suspect it could have a problem to plate 00:02:33.33000:02:33.340 heat exchanger so so we'll see what 00:02:35.88000:02:35.890 happens here now 00:02:50.80900:02:50.819 so we can see it's going to both what 00:02:53.63000:02:53.640 would expect it to be 00:03:06.72000:03:06.730 so this again a lot higher now than we 00:03:10.08000:03:10.090 would expect so this won't indicates me 00:03:13.86000:03:13.870 or it give me an idea that we've got 00:03:16.97900:03:16.989 blocks on a partially blocked way to 00:03:19.92000:03:19.930 heat exchanger so now what we'll do 00:03:22.58900:03:22.599 we'll have look inside and just just 00:03:24.33000:03:24.340 works if this shuts off but then we'll 00:03:26.58000:03:26.590 have a look inside and we'll strip it 00:03:29.30900:03:29.319 down we'll set the play he exchanger out 00:03:31.44000:03:31.450 we'll clean out and then we'll put all 00:03:34.83000:03:34.840 back together and then we'll do this 00:03:36.83900:03:36.849 again and we'll see what difference what 00:03:39.57000:03:39.580 difference we have I can see there now 00:03:43.02000:03:43.030 Byrne has just done down so if we if we 00:03:46.74000:03:46.750 measure temperature at water now we 00:03:48.50900:03:48.519 would find that the hot water is 00:03:50.81900:03:50.829 probably not not that hot because it's 00:03:54.03000:03:54.040 it's going on and off it's going up what 00:03:56.52000:03:56.530 was the temperature should enough you 00:03:57.72000:03:57.730 can know it's gone down now so that's 00:04:00.72000:04:00.730 the reason for the problem with the 00:04:04.22900:04:04.239 spoiler so let's go strip it down now 00:04:06.66000:04:06.670 and we'll have a walk as always if 00:04:10.02000:04:10.030 you're gonna take the combustion cover 00:04:11.91000:04:11.920 off a boiler make sure you guess if 00:04:14.91000:04:14.920 registered I'll get somebody else gets a 00:04:17.67000:04:17.680 registered to do it for you you've got 00:04:20.03900:04:20.049 two screws under here first of all 00:04:23.37000:04:23.380 what's in the power off and then we 00:04:26.25000:04:26.260 would do all our safety checks do they 00:04:29.61000:04:29.620 undo these two screws a bomb and then 00:04:32.52000:04:32.530 we'll just lift the cover off as I said 00:04:40.46900:04:40.479 this this has got seal on here so you 00:04:44.04000:04:44.050 must be kept safe registered if you if 00:04:55.50000:04:55.510 want to get to put heat exchanger just 00:04:58.40900:04:58.419 lift these flops down and then the plate 00:05:02.07000:05:02.080 heat exchanger is right at the back 00:05:04.44000:05:04.450 there to make it easier I'm going to 00:05:07.74000:05:07.750 take the burner out now this seems to 00:05:11.55000:05:11.560 say that's been serviced 2017 which 00:05:15.77900:05:15.789 normally when people write stuff like 00:05:18.00000:05:18.010 this and it means that it's been foolish 00:05:20.49000:05:20.500 down but when I look at the gas pipe 00:05:23.46000:05:23.470 here I can see and it's still got the 00:05:25.77000:05:25.780 seal on there so I would suspect that 00:05:29.43000:05:29.440 when we lift this out in a minute 00:05:31.32000:05:31.330 this has never been serviced but well 00:05:34.32000:05:34.330 have a look and we'll see the gas on 00:05:36.96000:05:36.970 this is the yellow tap just turn the gas 00:05:40.08000:05:40.090 off to it and then we'll just gonna do 00:05:43.74000:05:43.750 this number here and I'll check all the 00:05:46.32000:05:46.330 leads off and then we'll set the burner 00:05:48.42000:05:48.430 out 00:05:56.47000:05:56.480 [Music] 00:06:30.45000:06:30.460 it's not absolutely that bad inside no 00:06:38.59000:06:38.600 but I'll give it a good clean I've got 00:06:40.74000:06:40.750 I've got a tool 00:06:43.17000:06:43.180 playing exchanges so I'll give that good 00:06:46.96000:06:46.970 give a good plain you start look at that 00:06:49.69000:06:49.700 now and then you better sit afterwards 00:06:52.12000:06:52.130 once it's all cleaned if you want to 00:06:55.63000:06:55.640 remove the insulation anyway let's get 00:07:14.56000:07:14.570 back to this hot water issue at first 00:07:17.46900:07:17.479 what was doing now is will remove this 00:07:21.12000:07:21.130 exchanger here we need to turn the cold 00:07:26.77000:07:26.780 water off to this which is that tap 00:07:29.83000:07:29.840 where well so we will turn the floor and 00:07:34.39000:07:34.400 the return pax blow up the floor and 00:07:37.45000:07:37.460 that's to return off as well and then we 00:07:40.77900:07:40.789 will drill it down from this filling 00:07:43.06000:07:43.070 loop connection here I've actually got a 00:07:45.73000:07:45.740 filter on so I'm just going to drain it 00:07:48.40000:07:48.410 from here yep I've drained all the water 00:07:53.29000:07:53.300 out on the filter now and what can do it 00:07:57.52000:07:57.530 if I open this advant yeah this 00:08:23.10000:08:23.110 so I've turned that totally off that's 00:08:26.26000:08:26.270 the cold water into the boiler I'm now 00:08:29.44000:08:29.450 gonna go on open the hot tap you need to 00:08:34.87000:08:34.880 get as much as we can as much of the 00:08:38.23000:08:38.240 water out as we can just so we don't 00:08:41.29000:08:41.300 flood the boiler when we're doing this 00:08:44.94000:08:44.950 so that's the plate heat exchanger there 00:08:48.06000:08:48.070 and we've got two skills we've got on 00:08:50.95000:08:50.960 this side and then we've got on this 00:08:53.38000:08:53.390 side no I'm gonna come out fairly easy 00:08:56.77000:08:56.780 just need to make sure we don't get any 00:08:58.72000:08:58.730 water on the circuit board 00:09:36.65000:09:36.660 and then with this very very easy in 00:09:44.88000:09:44.890 there so you don't want to get that 00:09:48.09000:09:48.100 anywhere near you say it Bob 00:09:49.74000:09:49.750 I'm just putting those mops so that 00:09:57.66000:09:57.670 should play heat exchanger now I'm going 00:10:00.00000:10:00.010 to clean it out just don't lock in there 00:10:03.06000:10:03.070 to shake it up it's a muck in there so 00:10:19.23000:10:19.240 now we're going to just pass them the 00:10:21.38000:10:21.390 cleaner descaler in these all's here 00:10:24.87000:10:24.880 I'll do it over sad as well but it's men 00:10:26.88000:10:26.890 they're just this side because that's 00:10:28.50000:10:28.510 the side there is in contact with the 00:10:32.01000:10:32.020 heating water this side of it is the 00:10:35.10000:10:35.110 clean water so I'll clean that out now 00:10:42.98000:10:42.990 I'm just gonna pass some chemicals into 00:10:45.99000:10:46.000 this now to clean it help 00:10:49.11000:10:49.120 we've put the chemicals in there now I'm 00:10:51.67000:10:51.680 just gonna leave it for a while and then 00:10:53.83000:10:53.840 push it out with water you could put a 00:10:56.68000:10:56.690 new player um as well but obviously 00:10:59.53000:10:59.540 they're like hundred pound plus so if 00:11:02.74000:11:02.750 you clean out then that'll save you some 00:11:05.77000:11:05.780 money now we've got the plate heat 00:11:09.61000:11:09.620 exchanger back in just one thing well 00:11:12.91000:11:12.920 couple of things really to check this 00:11:15.43000:11:15.440 wire here sometimes it falls down and it 00:11:18.43000:11:18.440 goes in between the player so when you 00:11:20.62000:11:20.630 put it back in 00:11:21.43000:11:21.440 obviously it's not gonna seal so just 00:11:24.16000:11:24.170 make sure that is out of the way also 00:11:26.77000:11:26.780 you've got some or rings of some washers 00:11:30.40000:11:30.410 in back there just make sure you've got 00:11:34.12000:11:34.130 all the muck in so there should be 00:11:36.43000:11:36.440 farther then I'm gonna just put them 00:11:38.80000:11:38.810 back back in there and then obviously 00:11:46.50000:11:46.510 all I need to do let me just play 00:12:10.79000:12:10.800 while this is stripped down I'm going to 00:12:13.65000:12:13.660 take the expansion vessel out when I'm 00:12:15.36000:12:15.370 also gonna do a service summit so you 00:12:17.43000:12:17.440 may want to cook this video and just 00:12:19.65000:12:19.660 move forward maybe a couple of minutes 00:12:21.30000:12:21.310 or so but if you want to see that part 00:12:23.79000:12:23.800 of it and then great also what I'll do 00:12:26.94000:12:26.950 is at the end we'll I'll show you the 00:12:29.19000:12:29.200 difference in the display and we'll see 00:12:31.94900:12:31.959 if that digital display is now lower 00:12:33.44900:12:33.459 which hopefully it will be so yeah I'm 00:12:39.44900:12:39.459 going to cover this out the best I can 00:12:41.61000:12:41.620 in here and then I've got that little 00:12:43.98000:12:43.990 tool and that cleans dump gaps in there 00:12:52.97000:12:52.980 so I'm gonna give this a really good 00:12:55.01900:12:55.029 stripped-down service I've removed the 00:12:58.82900:12:58.839 expansion vessel on this there's just 00:13:01.29000:13:01.300 enough on top of that just been doing 00:13:03.63000:13:03.640 that and then it just stops out nice and 00:13:05.97000:13:05.980 easy and there's a little quick there 00:13:09.53000:13:09.540 you just pull that clip out one and then 00:13:13.22000:13:13.230 this pipe this just pulls out so well 00:13:18.30000:13:18.310 this is out I'm gonna do this I'm just 00:13:23.34000:13:23.350 gonna check this pipe make sure there's 00:13:25.01900:13:25.029 no no blockage in it and then I'm just 00:13:27.54000:13:27.550 gonna read pressurize this that's tight 00:13:31.29000:13:31.300 and it's still it's still at sea alone 00:13:33.60000:13:33.610 so I know that it's not being done from 00:13:36.06000:13:36.070 new so I might as well just do it when 00:13:38.61000:13:38.620 it's all stripped down I've connected 00:13:40.68000:13:40.690 mid pump onto this now I'm just gonna 00:13:43.80000:13:43.810 pump it up there's no pressure in this 00:13:45.24000:13:45.250 that's all 00:13:46.57900:13:46.589 obviously it's never being checked 00:13:49.04000:13:49.050 because it was sealed so I'm gonna put 00:13:52.19900:13:52.209 this up now 00:13:53.96000:13:53.970 there's different calculations with it's 00:13:56.25000:13:56.260 depending on the system I know I'm the 00:13:58.35000:13:58.360 top I'm up to about in bar so on there 00:14:01.38000:14:01.390 now it's just over one bar and as I undo 00:14:04.23000:14:04.240 like there the pressure will drop a 00:14:06.69000:14:06.700 little but I've just connected the 00:14:08.97000:14:08.980 expansion vessel back in now as I said 00:14:11.57900:14:11.589 very easy just to not put up one good 00:14:14.46000:14:14.470 thing about this boiler is everything is 00:14:17.18900:14:17.199 really easy to work on and then the pipe 00:14:19.53000:14:19.540 can 00:14:20.35000:14:20.360 that Piper come there and then that just 00:14:23.23000:14:23.240 connects it let's just connect them down 00:14:26.82900:14:26.839 there 00:14:35.43000:14:35.440 and then that just clips in there nice 00:14:37.84000:14:37.850 and easy I'm going to fill it back up 00:14:40.44900:14:40.459 now I've cleaned out in there but I'm 00:14:43.21000:14:43.220 gonna wash it out I normally use the 00:14:46.00000:14:46.010 system water so I've got a little whores 00:14:49.03000:14:49.040 there and then I was part of it walking 00:14:51.97000:14:51.980 down there I need to felt system back up 00:14:53.92000:14:53.930 first so I'm gonna do I know I've turned 00:14:56.25900:14:56.269 the water back on now I can see that 00:14:58.18000:14:58.190 that now is in line with the pipe work 00:15:00.81900:15:00.829 which means that's back on and I've got 00:15:04.66000:15:04.670 no leaks inside it's obviously check 00:15:07.38000:15:07.390 check inside they've got weeks I'm now 00:15:11.65000:15:11.660 gonna fill the heating side of it no see 00:15:15.69900:15:15.709 I'm pressure gauge I know 00:15:19.82900:15:19.839 one thing to point out on these is 00:15:23.73000:15:23.740 normally need to bleed the heat 00:15:26.41000:15:26.420 exchanger just to get the air out of it 00:15:47.97000:15:47.980 and then what said well do usually 00:15:50.92000:15:50.930 heating system at the warm and you see 00:15:53.35000:15:53.360 when you do this you better put some 00:15:54.91000:15:54.920 warm water down and then I just use this 00:15:57.51900:15:57.529 I just open it 00:16:00.96000:16:00.970 you need to bleed out on these anyway 00:16:05.06000:16:05.070 just open this a bit and then you can 00:16:17.97000:16:17.980 just use up then to put one down the 00:16:21.03000:16:21.040 heat exchanger and just clean and then 00:16:28.68000:16:28.690 just hope you help you with cleaning it 00:16:37.43000:16:37.440 on the bar obviously have to like it up 00:16:53.66000:16:53.670 God look inside now 00:16:55.74000:16:55.750 and a really good clean in there and now 00:17:02.16000:17:02.170 I'm just gonna put it all back together 00:17:03.87000:17:03.880 again 00:17:05.27000:17:05.280 the installation pod on this has got a 00:17:07.82900:17:07.839 little bit better damage on the best 00:17:10.14000:17:10.150 damage it's probably being underwater 00:17:14.22000:17:14.230 at some point up under condensate and 00:17:16.61000:17:16.620 what happen is when it's not being 00:17:19.29000:17:19.300 serviced for a while this in here can 00:17:22.17000:17:22.180 block up a little bit and the water of a 00:17:25.47000:17:25.480 common say doesn't get doesn't go down 00:17:28.43900:17:28.449 quick enough it could also be that 00:17:30.63000:17:30.640 there's a little part of this block so 00:17:32.91000:17:32.920 drain are somewhere like that that this 00:17:35.85000:17:35.860 boiler I got this boiler from whatever 00:17:39.42000:17:39.430 gas engineer this this remove me from a 00:17:42.24000:17:42.250 job I don't know the reason why it were 00:17:44.88000:17:44.890 removed but the good thing with these 00:17:47.55000:17:47.560 boilers is you can always bring them 00:17:50.49000:17:50.500 back to life 00:17:51.30000:17:51.310 you know they're really really good 00:17:53.13000:17:53.140 fallout 00:17:54.00000:17:54.010 there's post packing 00:17:57.79000:17:57.800 she's gonna put burner back in now just 00:18:01.28000:18:01.290 check that seal while we're around just 00:18:04.67000:18:04.680 make sure that it's no damage on it now 00:18:17.50000:18:17.510 just ten gas up I'm gonna put a test on 00:18:20.84000:18:20.850 gas as well there's a tent gas back on 00:18:22.52000:18:22.530 and then we'll just collect the leads 00:18:24.89000:18:24.900 back in as well if you have a look on 00:18:29.93000:18:29.940 the gas valve now red doll the sale has 00:18:35.72000:18:35.730 now been broken so I know now this has 00:18:41.33000:18:41.340 been stripped down and now it's being 00:18:42.80000:18:42.810 serviced well as when we first came to 00:18:45.80000:18:45.810 this nut that will seal our cross so 00:18:49.91000:18:49.920 just a little indication that it might 00:18:52.07000:18:52.080 not have been serviced in the past so 00:18:55.97000:18:55.980 the boilers all back on now the power is 00:18:58.22000:18:58.230 on and now I'm going to go run the hot 00:19:00.50000:19:00.510 tub and then we'll see what happens with 00:19:04.25000:19:04.260 the temperature on the front 00:19:09.39000:19:09.400 so if you've got the correct floor it 00:19:11.31000:19:11.320 would expect this really to go no more 00:19:14.94000:19:14.950 than about 70 really if if the floor in 00:19:19.17000:19:19.180 going through is fast enough obviously 00:19:21.93000:19:21.940 if the floor s not fast enough then he 00:19:25.56000:19:25.570 lost lightly higher 00:19:28.63000:19:28.640 so let's just see see weapons it's not 00:19:31.84000:19:31.850 going up now as fast as it will be far 00:19:34.02000:19:34.03000:19:42.57000:19:42.580 the main the main thing with this is we 00:19:46.26000:19:46.270 don't want the boiler cycling so don't 00:19:49.11000:19:49.120 want it to get into temperature and then 00:19:51.39000:19:51.400 turning off and then back on again 00:19:54.53000:19:54.540 getting up this temperature and turn 00:19:57.00000:19:57.010 enough 00:19:59.35000:19:59.360 we want this to stabilize 00:20:02.22000:20:02.230 temperatur 00:20:04.87000:20:04.88000:20:34.30000:20:34.310 this is by a high 00:20:36.12000:20:36.130 Lila 00:20:39.89000:20:39.900 no Sunday morning mayor sir 00:20:44.51000:20:44.52000:20:53.46000:20:53.470 I'm just going to power just check 00:21:02.80000:21:02.810 for the hot bodies talk outside 00:21:07.43000:21:07.440 as you can see now this is not doing 00:21:10.05000:21:10.060 like within the class obviously before 00:21:11.67000:21:11.680 it was going right up to temperature 85 00:21:14.94000:21:14.950 or so and then the boiler was showing up 00:21:18.56000:21:18.570 again cycling before that's would be 00:21:22.56000:21:22.570 clearly seen now he's staying up so 00:21:25.28000:21:25.290 we've solved the issue of no hot water 00:21:31.22000:21:31.230 what terrain hot water 00:21:34.67000:21:34.680 plates on this I'm also gonna check the 00:21:38.75000:21:38.760 pressure on the gas 00:21:42.99000:21:43.000 check them out 00:21:45.28000:21:45.290 this has been running now for maybe 00:21:48.37000:21:48.380 about four or five minutes and it's not 00:21:51.58000:21:51.590 that they're testing gas pressures 00:21:54.25000:21:54.260 that's all up here 00:22:00.04900:22:00.059 so that's it's all fixed and it's been 00:22:03.44000:22:03.450 serviced as well it's intact 00:22:09.33900:22:09.349 I've just got all the final safety 00:22:11.98900:22:11.999 checks to do now some good testing 00:22:14.11900:22:14.129 analyzer as well 00:22:19.50000:22:19.510 so as I said before I always remember 00:22:21.69000:22:21.700 you must be gas safe registered if you 00:22:23.97000:22:23.980 will be messing about are touching are 00:22:26.73000:22:26.740 doing outcome the gas side of flue side 00:22:30.84000:22:30.850 of gas common borders or gas positives 00:22:33.51000:22:33.520 are any gas appliance are all really 00:22:35.90000:22:35.910 yeah I hope anybody who's managed to get 00:22:40.32000:22:40.330 to end of this video has found it useful 00:22:43.20000:22:43.210 and thank you very much for watching 00:22:52.29000:22:52.300
