One thing I have noticed is that the hot water supply pipe from the top of the megaflo is constantly hot .. should that be the case or should it only be hot when hot water is drawn from the taps/shower?

Ok team - finally got someone in. Recharged air gap in megaflo. Took secondary circulation pump onto a timer that I’ve left off for 12hrs. And installed evohome hot water kit to track temp of water in megaflo. Overnight the cylinder temp has gone from 55deg to 30deg according to my evohome app...

I suppose the other solution could be a timer on the pump? I have a spare Drayton timer.. would it be possible to fit that to the pump so it’s not running all the time? Would it mean I’d still get hot water even when it’s not running?

Thanks for all this help guys. So if i took out the pump then the hot water wouldn’t circulate constantly right? It would just be on demand from the megaflo? The distant bathroom hasn’t been used for a year so feels a waste!

When you say expensive do you mean expensive to run? The bathrooms are not far enough that I’m bothered if I have to run the tap for 30 seconds or so (or wld it be significant?) to get hot water. But we have one bathroom in the loft the other side of the house so I guess far. If I can change...

John… more detail… the heating and hot water have been off for hours… but there is hot water circulating out from the megaflo *somewhere* … not rads or towel rails or any hot water using thing are on, no hot taps running. The water is circulating out from the top of the mega flow and looks like...

Noted and on the case. Is it normal for the pipe from the mains into the cylinder is warm when the hot water is on? It looks like there is a return pipe maybe from the towel rails that joins back onto the cold pipe ..

Friends i need your help! Ive moved into a house with a large conservatory attatched to the kitchen, but no door separating the the 2 rooms, just a large open double doorway (non-standard size).. With the winter approaching and the threat of a pretty cold kitchen im looking for ideas to keep...

We use hot water for the usual things - washing machine, dishwasher, washing up etc... One blast of 45mins was only enough for a bath and quick shower.. i have to set up 3 separate blasts for 3 showers through the day.. No radiators were on, no central heating at all. There is water running our...

John - you were right - towel rails are spurred off the the hot water before it hits the CH/HW valves so I guess i have same set up as you. To your question on how much cubic m of gas I’m using in a day - looks like it’s about 3?! 30kwh. That’s high right? One thing I have just noticed, my...

Yes following the bath it would go cold, but that could be due to the timer switching off too? Assume i would be able to trace the pipework to see if it was running from the boiler or the tank?

What's the best way to establish if its drawing water from the tank or just taking it from the boiler as it heats the tank..?

it is 300l - i'll give it a whirl for an hour and see if it holds. pretty sure it wont though given what i said above about how ive set up the timer and what i get out of it. in terms of boiler programmer - i had an evohome zoning kit installed, which is fine for the heating (as i say i got...

Thanks for the reply re the towel rail - i just assumed it was being taken from the hot water tank ... I had a plumber recommend i should put a timer on the pump that services the towel rails alongside some other recommendations which then surely wouldnt make sense? Im not sure what you mean by...

Friends! Please lend me your ears.. Is it 'normal' for towel rails to be heated directly from the hot water tank? Just moved into a place with an indirect unvented system, Bosch+Megaflo, and been having some real issues with efficiency/cost. I put a timer on the megaflo to limit waste there (i...
