Hi all,
My hot water pump has given up the ghost, so I need to replace it, but looking for a bit of advice as what replacement to go with.
This is how my system is set up: I have a cold tank in the loft, a Main System 18 HE boiler in the kitchen supplying hot water to a cylinder in the airing cupboard in the first floor main bathroom. Attached to this cylinder is a Salamander ESP80CPV which is the one that's died.
This pump supplies hot water to the kitchen tap, downstairs toilet sink, main bathroom sink and bath (not the shower which is an Aqualisa Digital Quartz Pumped - also in the loft) and en suite sink and thermostatic shower.
So here are my questions:
My understanding is that my current pump is a negative head pump. Is there any reason why this would have been installed rather than a normal positive head pump?
Should I replace like-for-like with another negative head pump, or could I save some money and go for a positive head one (which I gather are generally cheaper)?
Finally, I hear good things about Stuart Turner pumps? Based on my system, what would be a good one to go for?
Hope I've provided enough details for advice/suggestions. Thanks in advance.
