sequence 12000s for sale just over 2 year old runs well £180 + p+p just needs a bit of a wash which i will do when i get it swapped for the 10000s ive got to go in its place bit too powerful for running through my heatpump hence the sale otherwise id of kept it really good pump Oh ive looked high and low for receipt of purchase as been told warranty is now 3 tears on these pumps but no joy but never had any problems in the time ive had it great pump now sold

Dave,

Just a quick word about flow rates. If the only reason you're selling this is because the flow rate through the heater is too fast, flow rates are not hard and fast rules with heat pumps, there is a degree of latitude. But if you particularly would like a slower flow rate, you could fit a bypass around the heater with a gate valve to bypass any percentage of water that you want.

EG, with a seven turn gate valve, each full turn from fully open to fully closed gives (near as dammit) a 15% reduction in flow through a bypass. There will be a slight bit of tweaking required to make up for the fact that there is unlikely to be exactly the same number of bends and pipe length in both paths but 15 % per turn won't be far out.

Thanx for the info ive got a valve on the outlet and created a by pass but i thought why not just reduce power of pump and have full flow going through it this will give the contact time needed between water and heat exchanger better pressure in the heat pump as its not flowing through as fast giving me better heating capacity from the heat pump and im not having so much water un heated by passing the unit then thanx though for your kind advice got a new pump now hence the sale of the 12000s

No problem Dave, just thought I'd better mention case you weren't aware.
