Thanks for the replies,
I've just reversed flushed the heater with a garden hose and after a bit of
glugging and some dodgy stuff coming out reassembled the hoses. It now is a
whole lot better in terms of heat (but it still takes some time to warm up -
I think that must be due to the time the engine takes to heat the water in
the jacket and therefore not a lot I can do about it). As a check, when the
engine's up to temperature, the hose going in to the heater matrix is piping
hot while the exit hose always remains quite lukewarm - discounting a
blockage this must be showing that the heat transfer is OK.
BTW I replaced the fan motor with one out of the Dolomite 1300 and that
makes quite a difference to the volume of air.
One warmer Triumph driver!
thanks
Andy

Hi Andy,
The Smiths heater unit fitted to the Herald and Vitesse is not a
fantastic unit - much more powerful is the equivalent Delaney-Galley unit,
but I am assured that this was only ever fitted to Heralds as the valve
fouls the back of the engine on the Vitesses. Try reverse flushing the
heater core to get the muck out of it and this should at least improve
matters. Even better would be to take out the entire unit and clean the core
with some central heating descaler.
Probably not an option but interesting trivia, the Smiths heater fitted
to the first Heralds in 1959 was fitted with a heater core approximately
twice the size of that fitted to the later Heralds. This core will fit into
the later casing, but at least one of the holes in the front panel comes out
in a slightly different position. This earlier type core may be fitted to
other Smiths heaters so if you feel like getting adventurous........
Cheers,
Bill.
