Condenser Boiler Water Pipe

stebiz

I need a new boiler and have been doing some reading upon them. It appears that they are all condenser boiler types that get installed now and they need a condenser water pipe.

The boiler is situated in the back bedroom and the pipes to the bathroom some 15 feet away. If it's inside it would need to go down travel 15 feet then go up 2 feet.

If it went in the loft it would need to travel up 6 feet with a pump (I believe) and then travel 20 feet along the whole length of the back of the house.

Are there any alternatives please?

I'm no expert on boilers, (one will be along shortly) but the condensate drain pipe only needs to go into an outside drain. So, through the back bedroom wall and into the nearest drain.

Thanks but it's a bit more difficult I think. The boiler at the moment is on the right hand side. I have read about pumps being used in the loft but that is not easily accessible - another story and that would just be something else to break down.

I was thinking I could ask I roofer to cut a hole each side of the pitched roof and thread a wide piece of UPVC pipe so there is a hole each end so the plumber could thread his pipe through. Then if the pipe ever freezes (which I believe can be common) I can access the pipe easier. Is this a bit extreme or is there an easier way? I'm at my witts end. Didn't expect a problem in just replacing boiler.

Condensate pipes need to have a fall in them, so that the condensate runs away, so I don't think pumps are an option. Running the pipe horizontally through your extension roof to your bathroom waste pipes, is asking for trouble IMO, rain ingress, leaks etc.

Just a suggestion. Maybe you could run the pipe straight out away from the main house, across your extension, and into the gutter ?

The boiler experts on this forum will be along soon to say what is the best.

And, yes, freezing can be a problem

The gutter I'd be happy with but is a gutter an acceptable outlet?

Condensate is acidic so can only go into a plastic waste source as it will eat other metals, into an existing external foul drain, or can go into the ground using a purpose made soakaway which nutralises the acidity.

It can also be pumped away using a condensate pump which is a pump within a reservoir that pumps the water to any of the optional drainage sources!
You also have to understand that the further the distance the larger the pipe size needed if it is by gravity.

Very helpful. Thanks. Looks like I'll have to go with the soakaway although I may install another gulley and attach the pipes to the gulley.I can then throw some drain pipes across the front of the extension. A bit of a hassle.

My condensate pipe is run under the floorboards to anoutside wall via my garage into a drain . All approved by a corgi inspector ,it was installed 6 years ago

From my garage attached (spelling ? ) to the house it WAS run along the outside wall into the drain .

During the freezing winter the da.n pipe froze inside and cut out the boiler !

It now drips into a plastic bucket inside the garage , when it's nearly full I tip it into the drain

NO more freezing in the winter !

External condensate pipes are a pain in winter. I've covered mine in pipe lagging, but it doesn't help much. In freezing weather, an ice stalagmite forms in the drain. Over time, it grows up enough to reach the condensate pipe, and eventually blocks it.

If you can arrange an internal one, it will be a lot less hassle in the long run.
