Total nonsense, there is nothing wrong with condensing boilers, if they are installed correctly and commisioned correctly with good controls, unfortunately it is down to useless installations that cause the problems.
another plumber not knowing squat, condensates freezing that are put in according to M.I's are happening all over the country,
rainwater pipes are freezing too are they the fault of the installer ?

if the condense is run internally it will not freeze, simple and what has rainwater pipes got to do with condensing boilers, you seem to forget that condensing boilers are used all over Europe, and in countries far colder than the UK, the difference is installers there would not install the condense pipe externally.

what is got to do with rainwaters is
a rainwter is 2 1/2 inch, so if that can freeze, the recommended size of 1 1/4 will freeze more easily,
its not possible for always to run the condensate internally, and its perfectly ok to run then outside because the MI's say so,
so who knows best the MI's or you ?????

Me obviously, because if the manufacturers are saying that the condense can be run externally and they are freezing, then obviously it is NOT ok to run them externally, its not hard to work out, I think you will find that the German regulations forbid the condense to be run externally, why do you think that is?, we should learn from our European collegues.

It is not always possible to connect internally due to position of boiler or built in soil stacks wastes etc so perhaps the regs should be changed to say normal boilers can be fitted in that situation.
Or perhaps we should rip apart the bathroom or kitchen that cost the customer thousands to have fitted
And i think the point the guy is making is even if it is connected internally who is to say external part of existing waste will not still freeze have seen 4inch soil freeze up

I agree it is not always possible to run internally, but the installer needs to pick the best route, not the easiest, if the pipe must run externally then larger pipes must be used, 40mm or even 50mm if needed, insulation should be provided and trace heating in very exposed areas, it is down to the installer to provide a trouble free installation that will work in the harshest of weather conditions, we have to adapt to our environment

Make your mind up its either one or the other and in reality who had ever really heard of trace heating untill last year as its not something people needed to know.
Yep minus 15 for a few weeks is normal then and does trace heating work down to that temp.
A lot of customers decide they dont want an installation done in the best trouble free manner as it looks untidy etc etc

I have known about trace heating for years, it is nothing new, I always look for a route internally and normally find one, I never use overflow pipe for condense pipes.
Minus 15 is happening most years now, so you have to design a system for worst case, even if it is for a few weeks, it is at them times when your heating is most needed, at the end of the day, you do what you want, these are just my personal opinions, all installers have different standards and different ways of doing things, but all I know is I have installed numerous condensing boilers and non of my condense pipes have frozen.
Exactly John, we have to understand that the condense will freeze in winter, so we must find alternatives

If the stack is external, then connecting into an internal waste pipe will not prevent freezing any more than a dedicated 42mm condense pipe into the stack.
Then insulate it and use trace heating, as I said, this is my personal opinion, everyone is free to do as they please, but non of my installed systems have suffered from frozen condense pipes, as I do whatever I think necessary to prevent freezing
Your customers must be very understanding to allow you the luxury of a blank cheque when it comes to installing their drain lines.
