Pulsacoil for central heating?

Hi,
for my understanding, the pulsacoil is a:
direct, vented, economy 7 cylinder.

After doing some research I am considering to install 2 or 3 radiators in the house, and I probably should consider using an Indirect cylinder.
My pulsacoil is 10 years old and has always been problematic.
I am considering to change it with a different product, and maybe take advantage of the possibility of buying an Indirect cylinder.

Does anyone has some recommendation for brands or models? I find : Telford, Albion, Kingspan and others, but I wonder if you have a preferred brand, known to be associated to a high quality standard..

thank you

It is a direct unit as such.
But it is a thermal store.
The hot water inside the store is used to heat the DHW up via the plate heat exchanger.
Thus DHW at mains pressure.
You have many choice available.
But if only 3 rads etc.
Perhaps a combi boiler would be the better option for you.

I would recommend a Trianco Aztec system fitted with a cylinder if you really want. Heatrae also sell a version of this.
