Hi there, I recently moved into a rented flat - it's a nice flat and good for the money, but it's also pretty old and has (from what I can assume) a pretty old boiler system. When I moved in I didn't have hot water, the landlord and landlady haven't actually lived in the flat so when they came...

Hello all, I’m pretty clueless when it comes to this sort of thing but as we can’t have tradesmen in the house due to shielding I’m hoping someone can give me advice to help diagnose my heating problems. We bought this house less than a year ago and starting to find that there are several...

I have a shower running off bath mixer taps (i.e. not an electric shower) and for the last few weeks it has been driving me insane... hot water has been intermittent and water pressure is terrible. Plumbers can't figure out what is causing the problem. What happens is this: when I turn on the...

Hey :-) I wonder if anyone can offer some advice. My combi boiler isn't providing any hot water. The pressure is fine, the thermostat up. It's on, electricity is supplied and pilot lit it's only 3 years old. The gauge on the front is saying 20 degrees but doesn't go above this. Is there any...

Good morning everyone, Looking for some pointers. As the title says we replaced the old broken one with a new ST9400C. Transferring the wiring didn't seem too bad at all. I have attached a pic of the old wiring. Basically one wire for CH, one for HW and the loop from Live to 2 and 5 for...

I have a Baxi Combi 80e. I have an issue that the hot water doesn't run constantly when the tap is on and will turn to cold and then get hot again. The boiler will ignite whilst it's running hot and go out when running cold. This is actually worse when running the bath tap. Would this be...
