I have also been looking into heat banks and no matter how I assess,
one large or two small combi boilers comes out the best option all
around for me.

You should remember that a standard heat bank is good for around 40lpm
(at
60C). This is equivalent to 63lpm in combi delta Ts. That would require
5
cheap instantaneous combi boilers and a commercial gas supply to run
them.

That is nearly true. But most people don't need a commercial setup. Most
people are content on a bath fill of 5 minutes and a excellent showers.
A
combi, or combi's, can do that with less hassle in installation and lower
cost .

Where are you going to find a domestic combi able to deliver 30lpm?

I am not a fan of combi boilers as they provide no back up, which you do get
with an indirect cylinder and immersion heater, and the flow rates are a bit
poor. I have, however, now experienced my second good combi boiler. The

How many bad ones have you experienced?
