New boiler with filter in a dirty system

[Frankenstein]

Lets say I have a new boiler installed into a system which hasn't been very well flushed (or worse - not flushed), but I install a good filter.

If I clean the filter often, will the filter be able to protect the boiler?

I know that flushing is important and I've described an unlikely scenario, but has anyone come across this situation?

Every British gas install ive seen!!!

 

[ShaunCorbs]

at a minimum the installer should put a good cleaner in the system and do a hot flush, then run the new boiler with a magna cleanse for a few hours

Only if the filter manufacturer can guarantee a 100% pick up on first pass of water.
They nearly do claim that, but nearly won't mean dirt won't get into boiler, albeit hopefully very little.
Flushing a system won't get all dirt anyhow.

Are you going to install a filter after the boiler has been fitted?

What's the normal procedure?

On the Flipside If the installer is offering a flush why wouldn't you do it??? Are you looking to do it yourself?? I say why risk the warranty get it done properly

I'm not touching my system but I want to understand it.

I think that I need to clarify something:

I'm NOT going to install a boiler into a system which hasn't been flushed.

My scenario is hypothetical. How well would a filter protect a new boiler in a dirty, unflushed system?

 

[Riley]

Depends how dirty the system is. It's just a strange question

So a filter WILL fail if the system is dirty - I assume that this is the case even if the filter is cleaned frequently.

I know its a strange question - but I want to know how good a filter is at doing its job in the worst possible situation.

Do you have all these queries with the oil filter on your car or do you accept that they work?

[Riley]

Nothing is perfect. Particularly on an existing system. You never know how bad the internals are completely. I'm sure 99% of the guys on here would recommend one rather than not. It will not 100% protect the boiler but it's better to have one than not

On both my motorbikes and cars I change the oil filter and oil at the same time. Sometimes you can just change the oil and alternate with the filter changes (I don't do this). However I would NEVER put a new filter in any vehicle with the old oil. No I don't have the same queries regarding the oil filter on my car. I'm allowed to work on my car but I'm not allowed to work on my boiler. I need the expertise of qualified installers. I'm simply trying to ascertain how effective a boiler filter is.

 

[Riley]

Put one on - simple answer

 

[AlexGas]

You!ve answered your own question.

 

[Frankenstein]

You!ve answered your own question.

At last - thank you!

No - I've gone away and thought about it. There's a fundamental difference...

1. With a car you NEVER clean and reuse the same filter
2. With a boiler you clean an reuse

So my question is still not answered. Can the filter for a boiler handle a dirty system if you clean the filter on a regular basis?

 

[walterwhite]

I think your question needs to be directed at the specific filter manufacturer - there are many on the market.

Yes. Would you ever do it like that? Never is a 100 years for a variety of reasons.

 

[Riley]

You will never get someone on here to say that they work 100% of the time because you never know who might read the thread and misunderstand do something wrong and then look to blame this forum. I think the general consensus is that magnaclean and the tf1 are regularly used items. They do work differently to the filter on your car oil so perhaps do a bit of reading on them to understand what they do and how they do it.

It wont do the job that a flush will. It will protect the boiler to a certain extent but its not 100%. On a very dirty system the filter will reach the limit of what it can hold very quickly. If you are in the process of fitting a new boiler then it is the ideal time to give the system a good clean, and all boiler manufacturers require a flush a clean of the system as part of the install.

Personally if I buy a second hand car I use an engine flush first before changing the oil and if it has a K&N air filter then yes you can wash out and reuse!

This is probably closest to the answer which I was expecting. However if cleaned very frequently, will the filter continue to clean the system and gradually diminish the debris?

 

[rpm]

In post #9 you said you wouldn`t install a new boiler without the flush first and others have pointed out the issue with the warranty if you don`t so why are you still banging on about cleaning the filter to gradually remove debris?
