The Boilermate is an "integrated" store, that is the CH and DHW are run

The Sytemate has the CH run direst from the boioer with the store being
DHW only.

Thanks IMM - I see now.


All the controls/pumps etc in inside the neat casing in both. The control
systems are superb in both. The are not direct. I have a Systemate.
They are best available and state-of-the-art. They are self adaptive in
that they learn the boilers behaviour. They modulate the DHW pump speed
to suit the outlet temperature. A pump is on the mains water circuit,
well it is on the primary circuit, to pump heat into the plate heat
exchanger. They are also very reliable too.


They look like they are the best designed. I like the way that most of the
main pipes and pumps are presented at the front in an orderly way. Bit
worried about the clever microcontroller. But I suppose, in an emergency,
if it went pop, a little judicious bypassing with some wire would be
possible...

But, they do seem to have thought of everything - like pump overrun and
things. I had the fitter's guide off their website and it was
comprehensive to say the least.

Also look at http://www.rangecylinders.co.uk/prod...max/index.html
The Flowmax, which is a a well priced heat bank.

Ah - that must be what Grunff has - bit difficult searching for "range
cylinders" on google :/

Best have a direct "integrated" heat bank.

Heatweb - Also looks complicated like the Gledhill, but not as neat.

Albion - simple again, like the McDonalds'.

But expensive.

So far, I've seen two price lists. The Gledhill is pretty pricey, but
still worth it, for all the benefits I get (not least having a useable
5x6 ft bit of space back). However, I've seen one of the others (McDonald?
at around the £500-700 bracket depending on size. But after I'm finished
buying pumps, controllers, random bits and bobs I'm tempted by the more
expensive but nicely integrated solution.

Thanks indeed
