Simple question.

I am moving from a gas fired (combi boiler) central heating system to a 
wood burner fired (back boiler) central heating system.

The fires (as you might expect) are in different places in the house.

I can re-cycle the pump from the old system, but rather than it being 
horizontal, because of space, it needs to be fitted vertically in the 
circuit.

Will that cause any problems?

Cheers

Peter

Shouldn't make any difference - our pump is installed that way
(assuming that by vertically you mean the pipes go 'up & down' rather
than 'left & right'. You need to be able to get at the bleed screw in
order to get the air out of the pump - but other than that....

I guess some people might say that (depending on the age of the 'old'
pump, now might be a good time to fit a new one, to avoid the hassle
of doing so later ..  but that's your decision <g>)

We also have a lovely multifuel (wood & taybrite) boiler -
instructions with ours required a 'stat on the heating circuit to only
allow the pump to run when the water was above a certain temperature -
think it was 40 centigrade (from memory). 

The other thing we've noticed, having had 'conventional' boilers in
the past, is that the circulating water is not as hot as you'd expect
with gas or oil - but, in practice, this isn't a big deal.

Anyway - who wants to sit watching a gas boiler.... even a combi ??

The direction of flow should be upwards otherwise you can have 
problems with air locks.

Also, many pumps require the motor armature to be horizontal,
as they have water bearings, and it's important the bearings
themselves don't end up running dry in an air pocket.

The new Grundfos alpha I just fitted insists on the body being horizontal.

OTOH the existing grundfos ups 15/50 I just removed was fitted in 1994 and 
is still going strong and quiet. (The paint was faded)

Still, fit it horzontal with the connector not to the bottom

Yes, but this doesn't prevent the pump being fitted in a horizontal or
vertical pipe. IIRC, my pump came with a leaflet showing permitted and not
permitted mountings. And IIRC again, the only no-no was horizontal with
the motor underneath.

Andrew Gabriel is dead right with the fact about the motor shaft.  My
next door neighbour had his system PROFESSIONALLY installed and they
put the pump with its shaft in the vertical direction. After the summer
had gone and the system was restarted .................. the pump
didn't want to rotate did it. I was called in to administer a light
hammer blow to get it going.

That reminds me of when I helped my old man out upgrading his heating. 
He did most of the plumbing and I did the wiring (he couldn't get to 
grips with the idea of room/cylinder stats and motorised valves and things).

Anyway, all went well and the system worked nicely until one night he 
phones me up at some rediculous hour telling me that his RCD had tripped 
and, having gone round unplugging things and turning things off he'd 
eventually narrowed it down to the boiler. He said there was obviously 
something wrong with the wiring I had done and I should go around 
immediately and fix it.

I went round the next morning, and after some investigation it turned 
out that he had mounted the pump vertically instead of horizontally and 
it had begun leaking a steady drip of water which was running down the 
side of the boiler and into the wiring connection box.

He wasn't best pleased when I told him that it was his dodgy plumbing 
and not my dodgy wiring that had caused the fault!

Fergot to mention fitted with the body vertical!

That's common with a pump installed in any way if left unused for months.

Make sure it is light though

The shaft is ceramic and you can break it if you're over-enthusiastic
