Apologies if this has been covered elsewhere but I could do with a little advice if possible. I have an annexe with a shower and toilet that feeds into the main waste from the house. The main waste pipe is running clear, the blockage is in the pipe from the annexe. I have used drain rods and...

I've got a worcester dt20 programmer on the greenstar heatslave boiler but there is no sign of a thermostat in the house. I've not been bothered until now, just relied on programmer for settings, but I think I would like a thermostat with programming facilities in the house (the boiler is...

I thought I would ask here since members usually give more thought to these things than is generally the case. My old wood burner doesn't seem to be very efficient. It is also big. Friends have a Morso Squirrel which seems to blast out three times the heat mine does, despite being much smaller...

As a few people who have already been very helpful will know, I have been at war with my boiler for some time. The pump has been locking repeatedly, and that despite the fact that I am on my third inside 12 months. I got a tip that it might be micro air bubbles expanding and locking out the...

As back up for when my oil boiler packs up I am thinking of putting in an electric under sink water heater in the kitchen. Obviously at the moment the hot tap is fed from the boiler. It would be simpler to connect that feed from the boiler to the heater rather than use the cold main. Any...

second new pump in 12 months on riello oil burner is binding. I can free it and then it turns easily by hand, but obviously it is going to bind again after I put it back on. Any idea what would lead to this? Some kind of misalignment perhaps? Riello have a good reputation so I am not disposed to...

Any pointers gratefully received. Just replaced nozzle and pump strainer, reattached burner, bled through using nozzle on bottom, but getting the lockout code. Happens like this" press reset, goes into pre-ignition, electrodes fire (from sound of it) but no ignition, then back to lockout. So...

A while ago I had a lot of help with diagnosing burner lockout problem with my worcester boiler. Thanks to that I eventually found out my oil was contaminated. I cleaned the oil with a marine diesel filter, swapped out the burner pump filter, nozzle and in-line filter, and all was good. However...

I realise there are threads around this, but I haven't found the symptom I have, so maybe someone will be able to point me in the right direction. After the central heating has been on for a while a loud rapid fire knocking starts. It stops the instant I turn the tap on (have been turning hot...

I posted recently about Worcester Bosch boiler issue, and it turned out to be clogged filters from contaminated oil. With all the filters changed and the nozzle changed, and biocide added to the oil supply, it ran ok for a couple of weeks before cutting out again. It cut out and would not start...

Posting again because I am close to wits end with this. I have multiple visits from heating engineers and nobody can diagnose the issue let alone fix my Worcester boiler. I am getting closer but since I have already spent over a grand I want to try to do a bit of detective work on my own...

First of all, I am not going to try to fix this myself unless it is very simple, but I would like to be able to talk sense to a heating engineer when I can get hold of one. I had a plumber out to fix my Worcester Heatslave Combi boiler before Christmas. He seemed to have done it. The boiler ran...
