Light Commercial Boiler Reviews

[chris watkins]

If it is an old dirty O/V system might be an idea to leave it that way but I understand some are using large plate heat exchanges instead of LLH that way new boilers with small water ways can be on sealed system while old system remains open.
Although risk of plate blocking they are a dam-site cheaper than a boiler or two (spare could be left on site ready).

Not done personally just heard about, would be interested to here from anyone that has.

Instead of a plate get a tube heat exchanger

Just fit a 45kw vaillant with a circuit splitting plate hex. worked a treat..boiler seems good but only been in a month..we usually fit ATAG's but controls aren't as user friendly personally speaking..

We all know you take a chance putting and new boiler on an old system, the plate is a good idea but it means two pump if you have two boiler that's three pumps,the nice thing about a plate is you can strip it down, never ever fit a solid one, a plate will bump he cost up a bit. A tube one as Ermi says will do also but not many around make them any more, made to order perhaps, you could suck it and see mag-filters and mesh filter.

Quinta for me. Simple little boiler. Well built never had issues with the well maintained ones. Well apart from a h/e that corroded. But that's one. Never got along with Atag myself. Had too many bad experiences with non user friendly controls. But they obviously may have changed now.

Also, go with a plate, as said one that splits down into sections. Strainer and dirt separator is a must

There the same old folk confusing controls still.

i would go with the plate exchangers aswell. we fit them on all our systems where we connect to existing systems. If you did want to seal the existing side and are worried about pressurising the steel pipework, you could look at a spill and fill system.
