I belive the Slimline also has a thermostat. It is also suitable for many conservatories, as it can often be fitted on the narrow strip of brick wall between the door into the house and the frame.

We have a single glazed Victorian conservatory, there is a rad in there, fitted by a previous owner, but we have turned that off as it would just be waste having it on all the time and it's to slow to heat up the space.
But fitting a one of these fanned heaters would be possible option. As it is long thinner shape along the side of the house we have plenty of house wall space, ( as well as low down space on the conservatory wall - but the pipe runs would be longer)
So any suggestions as to which is better, high mounted blowing down or lower mounted blowing into the room (I sort of feel that the former seems better)
I fitted a lo-line recently for a friend in a conservatory. He had enough wall space, nice and neat in the corner on the house wall. It was taken off the 15mm rad circuit as it would have meant ripping up a solid wood laminate floor to get a dedicated 22mm circuit most of the way, and as I suspected did not initially perform too well. I had two choices:
Because of the way the system was piped up. No. 2 was best. The flow increased and it performed well. The original pump pumps upstairs and down and the new pump only downstairs, so downstairs has pumps in series, well half of the output of the original pump. I was thinking about wiring the second pump into a stat that controlled the Myson and the second pump, but there again access for wiring was a problem. So far no excessive noises. I wanted to fit a pump just before the Myson, but no room at all.
All a bit semi-temporary, as a thermal store and condensing boiler will be going in soon.
Sorry. I fitted a slimline, not lo-line. They bill it as a conservatory heater.
Lower mounted blowing across the floor. Hot air rises. Some high mounted units don't blow hard enough to get to the floor, before the hot air starts to rise up.
If an extra pump is needed for a conservatory heater, then are there small pumps available? The standard CH pumps seem too large to me.
A zone valve would be fine instead. You can zone off with individual pumps or with zone valves. Pump zoning also requires one way valves which are hard to find in a quiet configuration. I much prefer valve zoning, particularly if the main pump is a good one, such as a Grundfos Alpha.

I prefer pump zoning as valves restrict flow. Look insude a 22mm, and you see a 15mm orifice. Pumps are more reliable too. If using a fancoil heater you will need flow through it. 90% the existing CH pumps can't do it in a retro fit, unless the fancoil is near to the boiler/pump and the pipes are
22mm most of the way. Conservatories at times are at the end of the CH circuit with only 15mm conveniently available.Small pumps? Grundfos make a small secondary circulation pump called the Comfort for secondary circulation applications. I see no reason why it can't be used on a CH loop, but check with Grundfos if you can get hold of anyone with sense there. It comes in many variations, with integrated: timer, stat and non-return valves. A basic unit with integrated non-return valve may fit inside a fancoil units case (depends on units of course). It can be switched on via the fancoil wall mounted thermostat or programmer/stat and give extra flow to the fancoil unit. It is not cheap around £100. There may be other makers making small pumps, but I haven't seen them, perhaps others may know of one.
If cheaper smaller pumps were available, then a 3 zone setup: upstairs, downstairs, DHW cyl, could have a small pump for each zone taking up little space at all.
