Hi pumps after the boiler won't work . however a mains booster pump can be fitted on the mains pipe before it splits off t boiler ( hit) and cold outlets. This would givevtyhe hot and cold equal pressure. Here is a Stuart turner mains booster pump, salamander do one too . http://www.stuart-turner.co.uk/products/flomate/mains-boost/ This will boost by 1.5bar.
Thank you for your very prompt reply. This pump would only seem to operate if my water pressure drops to 0.6 bar. I believe that I am already running at about 1.2 bar. Or am I being silly here? Are you saying that this pump would maintain 1.5 bar regardless of the number of outlets I have open?
Sorry, misread the spec .... they are talking about flow rate.
Hi , thanks for that . if your pressure is at 1.2 already then I would recommend the grunfos homne booster.it incorporates a tank and pump that can operate at 3 bar .these work very well . But how many bathrooms are you ended ng to run at the same time? http://www.anchorpumps.com/grundfos-3-0-bar-home-booster-240v?gclid=Cj0KEQjwvo6wBRCG3Zv92ZSLlIYBEiQA5PLVAlKZqRtmxXxtu4GQEPDRcXEdITqba9szTkJGDIVPbOUaAsMD8P8HAQ.
Please be aware that your combi will be limited to a certain flow rate. This is to ensure it goes through slow enough to get heated up
Hello. Thank you for the additional information. I wish to run 3 bathrooms at the same time. I know I have the wrong boiler for this but wish to make the best use of it rather than replace it. I think the unit you have suggested above may well be the answer. It will certainly make things a lot better. Thank you.
Many thanks indeed
