Central Heating pump for 5 rads?

[nick69]

Should I just use a 15/50 on speed 1 or can you get a smaller pump for smaller systems?

All rads are on the same floor as the pump btw.

Cheers

15/50 on speed 1 is perfect; other pumps may be cheaper but noisier and won't last as long.

grundfos alpha 2 would be even better but not worth the money imo.

Thanks for the help. Double the price to go from 'A' to 'B', dont see the point of the alpha 2 myself but hey.

Sorry to bring this back up but ive just been given a new 15-60. I assume this would also be ok to use on speed 1, can someone just confirm yes or no please?

 

[mickyg]

yes

Also depends on which boiler(low water content and combi) as speed 1 might not be fast enough to clear heat and boiler would get noisy

Its for a Solid fuel range heating circuit.
