A gas air heater for the entire house is much simpler again..

Takes up a lot of room to make a decent quiet one.

No it doesn't. Normally quite tall and not very wide or deep.

You only have the one room, then?

Works fine for the whole house.

Then it has trunking of some sort.

Yes.

That takes up more space than pipes.

Yes, but that isnt space where the people
are, its under the floor or in the roof space
where even your tiny houses have plenty
of unused space. And the total system is
much more reliable than a water based
system and much easier to fix with much
less to fix if anything does go wrong.

You can't run it in the loft space or there would be condensation & mould

We can and do, just use insulated ducts.

your climate is warmer & drier. We get condensation, causing mould. That's not on. Insulation reduces but doesn't eliminate it.


If you run it underfloor that is either above or below
the insulation. Below means excess heat loss,

Not with insulated ducts.

which fails to meet BR.

Wrong.

Above means a good bit of complication & extra material.

Most of ours have concrete Slabs on the
ground now so its done in the roof space.

Not saying you couldn't make a neat job in a new build.
But for most a wet system is going to be far neater.

Thats bull****. No stupid radiators in all rooms,
at most an air register which is vastly neater.

The lack of rads is the big upside.

A massive one.

in a minority of cases yes. For most houses rads are a minor inconvenience.


I found the noise a real problem during conversations,
it wasn't loud but still enough to disrupt audibility.

There is no noise with one done properly.

I've not experienced one that good. There is only one mfr of such systems here, Johnson Starley. They used to be more popular, but are all but gone. It's hard to find such setups in use in domestic houses now.
