Hi all, first time to post on here, looking for some help from knowledgeable/experienced people here.
We're installing an ensuite and I'm looking at my options to get a decent shower. The shower head I want uses approx 15 - 18 l/min at 3bar. The shower head will be fitted to the ceiling. The CWS is in the loft but is only a joist height above the ceiling, hence a negative head pump looks necessary.
I've loked at pumps - looks like Stuart Turner monsoon is the best to go for, just wondering what pressure I should opt for, there are 1.5, 2, 3 and 4, bar options. What difference does this make - is it simply the flow rate they can kick out or does it need to match the shower head? I was going to go for the 3 bar option as the shower head specs say 15 - 18 l/min at 3 bar which is enough.
I've also researched conenctions for the pump. I'm happy about connecting the CWS from the tank in the loft. The hot water tank has a blanked off connection on the side, which looks like a 22mm threaded connection, just below the weld at the top. Can I use this as the hot water feed to the pump? Also what else should I be fitting, i.e. to remove air etc etc?
Final question/concern - the flow rate into the house is roughly 18 l/min at the kitchen cold tap. If the pump is using that is there a risk of draining the tanks and damaging the pump, or will the pump shut off if water level drops? We will need to be able to use 2 showers at once as well so surely the tanks will drain faster then they can fill?
Many thanks in advance for any responses.
