Depends on the burner design. A highly efficient spot rated burner
(non-modulating) coupled to a heat bank can be very efficient overall.

Ok, but that's a different game. The background was a more
conventional system.


Many top end developers are fitting Myson Kickspace heaters in kitchens.

Presumably this is to save wall space that would otherwise be needed
for a radiator.........

We had one of these (actually a wall mount version) in a previous
house to heat a stairwell and landing. It was effective but pretty
noisy. I wouldn't have wanted it in the kitchen...

These require a high temperature flow for efficient draught free operation.

Wouldn't the main point be to get enough heat output?

The solution used to be an integrated thermal store as it provides 75-80C
temps and a spot rated burner boiler always set to max temp. The efficiency
was good as the burner was highly efficient with design maximised for a set
rate.

Condensing boilers have advanced recently so now some approach it.. A DHW
only heat bank with one high temp circuit taken off the heat bank for the
Myson(s) and the CH circuit left to modulate on a condensing boiler. When
the heat bank requires heat the boiler runs up to full temp. When back on
CH it is left to modulate.

I see what you're saying but it sounds like a lot of extra complexity
- presumably an extra pump for the Myson circuit??
