Hi Could any one tell me if the GRUNFOS UPS 15-60 130 pump is strong enough to pump water round my hot water and gravity fed central heating system which has 12 average sized radiators. I have an averaged sized 3 bed house. The reason I ask is because some of my radiators down stairs are hot @ the top but ony warm @ the bottom. I have taken off 1 of the offending rads to check out if blocked & it is clear. To make sure I turned off most of the other rads & hey presto its hot top & bottom ? Thanks in advance. :?:
Hi ALDA thanks for the reply by what you are saying I assume you think the pump is possibly big enough. I had balanced the radiators down to about 1/2 a turn open but it still feels that the radiators could be hotter at the bottom. Thanks again for the feedback. PS could not reply sooner because I could not log in, I emailed the powers that be and now i can.
