Outdoor, condensing boiler

turniton

Hi,
we are buying a house and I got a plumber to do an inspection for me.
He says the boiler is long time gone and need to go to a happy place

I do trust the guy but I would like to get info , for myself more than anything.. at least not to sound/look totally stupid when i talk to him

The condensing boiler seem to be the way to go.. and as far as I understand a 27Kw>35Kw will do for me (110 sq meters, 2 floors, C3, 1 main bathroom wih shower)

I ve seen many models on line.. I ve been told Firebird are really good (but expensive)

I just would like to have ideas and suggestions..

You will find that most of the lads here would go with the Grant, though I personally find most of the popular makes of HE boilers good. The really important thing in your case is to make sure that you are not putting a lovely new boiler onto a dirty system. You need to make sure your system had been properly power flushed or you will have your boiler working like a 10 year old one in just a few months. Use this opportunity to upgrade controls and install zones if not already done. Insulate all exposed pipework. Make sure no leaks. Add inhibitor and you will have many good years of trouble free service.

Understood Wearb, thanks a mill

just had a quick look online.. companies that do power flush cost between €400>€500, would that be correct?

Wearb

That sounds about right. I know most people think this is very expensive, but if done correctly it is certainly worth it. That is if you have any other problems, such as leaks sorted out before fitting the boiler. The main thing is not to have fresh water being introduced into your heating system after initial filling.
Someone on boards might be able to recommend someone in Galway. There are a few chancers out there. If all else fails, contact your boiler manufacturer for a recommendation.

I ve another question (which might be stupid, but I ve to ask)

would the power flushing cause the radiotors to spit out a bit of dirty water?...

I m planning to do the all second floor (new laminate floor), so should I wait until the power flushing has been done, to avoid any problem?

It would not cause them to "spit out" onto the floor (unless they are leaking already). If done correctly, it should remove any gunk built up in them. There should not be too much sludge, as it would indicate a plumbing problem that you would need to sort out before fitting the new boiler. I would prefer to have all the associated work done before fitting any flooring.

Make sure whoever you get uses quality chemicals. Fernox, kamco or sentinel would be the better ones

Thank you both guys.
The plan is coming together...
