From a comfort point of view radiant
heat from the ceiling
is not a good idea as ones head needs
to be cooler than ones feet.
All heat rises so radiant heat from the
cieling is going in the wrong direction.
During the past few years there has
been a move to install it in offices
where there is a requirement for
cooling during the summer, in situations
where the summer cost of cooling
is greater than the cost of winter
heating this seems to work as cold
air falls.
However, in these situations installers
put in masses of insulation, lots more
than would have been installed when
yours was done.
Radiant under floor heating, where the
wires or pipes are installed in concrete
is not a good idea as the mass of concrete
is slow to warm up and, even slower
to cool down. If the sun shines into
your room, then you can spend good
money in the morning to heat the room
only to find the sun comes out a bit
later and suddenly you are boiling
needing to let the heat go through
the open windows.
Light weight radiant under floor heating
where the pipes are installed just under,
the wood floor and , the floor is quick to
warm and almost as quick to cool, is the
best way to go.
I lived with base board heating which
I installed, for 28 years, I had thermostatic
valves in all rooms and the home was split
into two zones living and sleeping.
This worked for me, my
heating bill was always the lowest of six
identical homes and my home was always
comfortable. T shirts and shorts were the
order of the day at all times of the year.
Nine years ago I added a sun room with
underfloor heating, this worked well for
all year round living, except for the sun,
once the sun came out it was impossible,
too hot and so bright you couldn't see.
