1) The Infinitely Continuous Combi -

Heats cold mains water instantly as it runs through the combi. It never runs
out of hot water. This is the most common type of combi, generally having
lower flowrates than Nos 2 & 3 below. The largest flow rate instant combi is
a two bathroom model, 22 litres/min ECO-Hometec. Being a condenser it is
very economical too. http://www.eco-hometec.co.uk

Sorry to be pinikity but it's hard to compare the flowrate of the ECO
hometec range since they quote their flow rate at a lower temperature
rise of 30K rather than the normal 35K that other manufacturers use.
However the ECO 38 is likely to have a very good flow rate since it
has a power of 46kW. Their efficiency figures are also weird because
they use a figure of 110% to represent 100% efficiency!

Further more that are extremely expensive.

However I'm sure they are very good.

BTW: Worcester-Bosch do a 40kW Combi. Again they are quite expensive.
Once you go above 30-35kW the prices rise rapidly.
