I think a couple of people installed Heat Banks last year - what are your
views having run them for a while?

Can anyone explain the relative merits
of heating the heatbank directly or
indirectly?

When direct "all" the boilers heat goes into the store. When indirect you
are relying on the efficiency of the coil.

Why would I choose to make the primary
circuit pressurised or vented?

In theory pressurised has little advantages over vented when using a heat
bank, as long as the system is fitted correctly and inhibitor is used and
replaced every 3-4 years. Pressurised does away with the F&E tank, in a heat
bank this can be integrated with the store.

Are there any other heatbank
suppliers than DPS or Gledhill?

The flowmax is a heat bank these days, although they say thermal store.

Many of the underfloor companies provide their own heat banks (usually made
to order from other companies)

A while ago someone recommended the Worcester Greenstar(?) boiler, any
more
good/bad reports?

So, far so good with these. Just make sure the system is cleaned before
installation and correct inhibitor used and replaced every 3 - 4 years.

Use an integrated heat bank, where the CH and DHW are off the store.
