If I get the plumber to replace the heat exchanger for a brand new one, will that increase the flow back again? I decided instead of using my normal local guy, I found a guy in Dartford that specialises in Vaillant boilers, so I think he'll probably be the best one to deal with this for me...

Actually, I was wrong, I re-tested last night and actually I have. 13L per minute cold tap - approx 3.0 bar pressure 6L per minute from hot tap - don't know the bar I assume this means my boiler may need a service to get it back to the original 9L a minute which would be a 50% rise in flow...

I had been thinking of installing a new condensing boiler and getting maybe a 35kw one, but the more I've read about condensing boilers, the heaps of issues and repairs everyone seems to have with them. My house is 2 bedroom, 6 radiators, one shower. So not massive. I've had this...

I think it is very slightly in thickness. 104 fins to 102 fins. The cover is identical for both the 824 and 828 as far as I can see. All other parts have the exact same part numbers. The burner has slightly larger holes in the 828 than the 824. Do you think my Plumber would say yes or no to...

About 9 litres per minute.

The TRV's do make noise, but the Drayton ones in my experience have been very quiet. You hear them if you're next to them, but you don't if you're in another room. Plus, in the few weeks I've had them installed, I would say I've heard them adjust maybe, 4 times in total for a period of maybe a...

My cold tap is very powerful. Approx 3 bar pressure from the cold tap.

Drayton Wiser is very good. You have wireless TRV's on each Radiator, and you can control the temperature in each room individually. They're on Amazon Black Friday deals at the moment.

I have a Turbomax 824e. It works great and I don't want to replace it yet. It is regularly serviced but the pressure in the shower has always been weak the entire time I've had the boiler (20 years). It's a 24kw boiler. When you turn on a tap, hot or cold, the shower slows down to a trickle...
