the atmos one is the older less efficient heat exchanger design but in essences its the same idea so lime should in theory affect them in the same way.

Which in your opinion is the better of the two, or are they on a par.

That does not make sense! How can the radiator be hotter than the flow temperature?

the intergas is better,the boiler is more efficient, smaller, longer flue lengths and has designed out a problem with the drain that the older types had. the negative side it made the flue off centrer and has an external expansion vessel

No idea Dave, I wondered that as well.

Currently the fittings on the boiler are recording 68/53 the rads are 82. with a digital thermometer.

I have clamp on pipe stats I'll try them later. :thumbright:

The return could be put down to heat loss through the cold area, but not the flow. :dunno:

You can thank Atmos for that! They told intergas no until we hounded them mercilessly! in fact intergas asked us to write to them as they have a lot of respect for the Gaff here :wink:

an over sight maybe?

I did get the impressing of 'nothing to worry' about when I was at intergas HQ. was also told that Holland has hard water as well...
From experience we've found the "not a problem" attitude is a little unwise. We too were told that scale wouldn't be a problem and it is arguable that it is less likely to scale than plate hx with it's thin water ways. It is also true that the design helps to "flush" scale through. However as you all well know if you put a device in a hard water scale will come to some degree! As it mentions in the previously posted doc scale inhibitors help, seemingly different ones seem to perform to varying degrees of success depending on where they are in the country. Ultimately if you really want to solve scale you need to fit a water softener! :-)

It's quite interesting John, to count all the eventualities when changing from a low pressure system to a high pressure one.

Shower valve don't like it.

Old washing machine hoses split.

Radiator valve seem to be ok, as does the old pipe work and radiator.

Removing the cylinder, meant I had to swap the hot over as well as the tank cold to the shower etc.

Think I'll start turning the water off when I go out :lol: :lol:

One of the computers is ok it's a MAC. :mrgreen:
