activeviii Posted December 5, 2015 Report Share Posted December 5, 2015 Baxi due 28 he has decided to play up. Water is not hot. Warm, just not hot. Radiators are the same. Could do with a service as well Anyone need a couple pound in there pocket? I'm not allowed to play with it no more. Quote Link to comment Share on other sites More sharing options...
Winston72 Posted December 5, 2015 Report Share Posted December 5, 2015 im guessing you mean baxi duo tec 28 ,potentially your diverter, diagnosis, part sourcing and replacement + servicing = more than a couple of quid ,= in the region of 280 Quote Link to comment Share on other sites More sharing options...
Doc Holliday Posted December 5, 2015 Report Share Posted December 5, 2015 If both the rads and hot water are only getting warm I'd check the primary thermistor first. Simple ohms reading should tell you if it is behaving or not. Most thermistors offer more resistence when they get warmer. Baxi should be able to tell you what perameters you can expect. As a rule of thumb, if the water is only getting hot when the heating is on and only warm when the heating is off then I'd be inclined to look at the diverter valve. It always makes me laugh though. People expect boilers to last for years (not aimed specifically at the OP but just from my own experience) and don't tend to get them serviced yet they will quite happily pay £XXXX for a new car every few years and have them serviced regularly. It's a strange relationship folk have towards their boilers. Quote Link to comment Share on other sites More sharing options...
activeviii Posted December 5, 2015 Author Report Share Posted December 5, 2015 I'm thinking diverter valve now after a bit of reading. Baxi do a device kit so there's a start. For the sake of £8 got the thermostat and it has to come out for the valve to be serviced then no lose really. I'm thinking there might be crud in the filters as well. I emptied the spiravent and magnaclean and they were rather dirty. I had a Rad moved in the summer. All rads isolated so just the drops one one Rad drained. Once the system was refilled and vented it started to make a different noise. Nothing bad just you get tuned into what things sound like and after refill it was different. Something else I have just noticed, top air vent has been weeping so looked at the one on the pump, that also is leaked. The top one has no screw in plug. OK, so anyone near here want to service my boiler, lol 2 years ago done last but chaps not around no more. It's baxi duo-tec 28 Install 2009 Full flush, twice and didn't do properly first time. No error codes showing. Quote Link to comment Share on other sites More sharing options...

imissalot Posted December 5, 2015 Report Share Posted December 5, 2015 I had one off these and hired a boiler cleaner ( big pump cleans the system) worked a treat Quote Link to comment Share on other sites More sharing options...

daz2202 Posted December 5, 2015 Report Share Posted December 5, 2015 (edited) Turn everything off and when it's all stone cold turn on the bath hot tap. If the heating flow pipe warms up then it's the diaphragm in your diverter letting by Edited December 5, 2015 by daz2202 Quote Link to comment Share on other sites More sharing options...
