Can you expand a bit on that for me please as I am a plumbing novice! My main concern is that I could be losing out on the cold pressure since it is going up another floor, round that floor a bit then back down into the bathroom when it passes the bathroom feeds on it's way up to the tank...

Hi All, We are in the process of getting our bathroom redone & it has currently been stripped to it's shell. We have an unvented Santon tank loacted in the loft that was fitted last year. As part of this refurb we need to move the mains supply pipe to the tank in the loft onto a different...

Thanks Tony - You were right it does not work properly. Off to the gym to shower now!!

Hi Again, Was wondering if different water pressure (hot & cold) to a thermostatic valve will damage it? Still got the cold to the shower using the cold water from the tank in the loft (gravity)while the hot is coming from a mains pressure unvented cylinder. Will be like this for a week or...

Thanks for the quick answers. Are you kids teenagers or has it been emptied under normal use & how many bathrooms do you have? So much for the manufacturers guidelines! Looks like the 250 will be a better option for me then - will also switch to a Santon as it not the first time that I...

Finally got round to changing to an unvented system but cannot decide what size megaflo to go for. The house is currently 3 bed but will will be 4 bed with 2 baths in the future. Trying to decide between the 210 or 250. The Heatrae guides indicates that the 210 will be fine but some...

Sorry been away for a few days so have not been able to reply. The current shower with pump provides more than 17ltr a min. Any recomemndations on who to use in South West London to fit an unvented system?

Hi, Done the tests this evening. Combined flow rate of outside & kitchen tap is 15 1/2 ltrs per min. Flow rate of klitchen tap by itself is 10 ltrs per min with the pressure at the outside tap being 1.5 bar. The pressure went up to over 5 bar when i turned off the kitchen tap if that...

Thanks - will do the suggested tests & post the results when I get home.

Thanks for the quick response. The outside tap has a flow rate of about 16ltr a min but I assume that there will be more than this going to the megaflo as the pipes to that will be 22mm as opposed to 15mm to the outside tap?

Hi All, Need advice on what to do with our hot water system. Current set up is a system boiler (Potterton Suprema 60he), copper hot water tank in the bathroom & cold water tank in the loft. Stuart Turner twin 2 bar pump connected to shower in the bathroom. The shower is great at the...

Thanks - got the 32mm now.

Hi, I am in the process of getting my water main renewed into the property. The waterboard are going to renew with a 35mm pipe from the main up to my external stopcock.. Then my plumber is going to use a 25mm pipe from the external stopcock to the internal one. I was under the impression...

thanks for your comments so far. So if I have undertood correctly the custom tank will create more problems than it solves? I have looked at the Bosch HiFlow but this would mean relocating the bolier to the understairs cupboard (it's currently in the kitchen about 4 metres away from the...

Sorry forgot to add that - two adults at the moment. But there will be kids in the near future. So my plumber is wrong about the high flow combi's being able to cope with two showers at the same time? If so it looks like a custom tank for now then a Megaflow if / when we do the loft...

Need some advice please on a plumbing \ heating solution for a 1930’s 3 –Bed Semi in South West London. Currently have one bathroom with a mixer shower in the bath but plan to go into the loft & have a shower & maybe bath up there as well at some point in the future. Water pressure in the...
