I found that heating the hot water for 15 mins was enough - but probably had a smaller tank and don't use much hot water. I ended up leaving it off - just set the boost to 15 mins and boosted when I needed it. I would think an hour would be enough to heat the tank - but I suspect once you start...

Thanks I was thinking that the cylinder would be full and would supply on top of the cold but I guess what is taken out of it will be replaced as it’s being used so I won’t get anything above the mains flow. Just have to hope that I can get mains flow and that the outside tap is restricted so...

Checked the outside tap from a hose pipe and that gives about 14 l/m. So something is causing it to reduce to 7 l/m by the time it gets to the kitchen and bathroom. I guess that needs to be sorted out otherwise my mixer shower won't be any good? What should I expect if I'm getting 7 l/m from...

There's no room for the tanks in the loft conversion. It's almost a new floor with a flat roof. It's a bungalow and getting what my sis-in-law calls a shed-on-the-roof. The aqualisa was at my previous property. I don't remember the flow being much greater before the water softener was installed...

Reading - a shower takes about two thirds hot and one third cold water - does that mean my unvented system should get a max of 21 l/m? That sounds like a lot and two thirds hot water also sounds like a lot. The aqualisa site says their showers give 13 l/m on normal and 18 l/m on boost. I felt...

Thanks. Pressure gauge sounds a good idea, I've just ordered one - need to find somewhere where it will connect when it turns up tomorrow. The shower was installed on Saturday so I wouldn't have thought the filter would be a problem. I measured the flow and it's about 7 litres / minute at the...

Thanks. He did some quick checks but I didn’t write down what he said but he said it wouldn’t be a problem. I’m not sure he understands what I expect or how important it is. I am testing this on cold. The shower is 9.5 kw and has two elements. I’m guessing that the temperature control just...

Thanks - I’m hoping it will be better. Doesn’t the electric shower also take the cold mains pressure? I’m guessing that the hot water from the cylinder will mean greater flow? But how much? How much extra do you get from an accumulator and can they be placed anywhere? The boiler and cylinder are...

I am having a loft conversion (including extra bathroom) which will end up with a flat roof and needs an unvented system as there is no room for tanks. The plumber assures me that the shower will be no problem and similar to the pumped aqualisa quartz I had before. One of the reasons for the...
