Anyone used or any experience of a Potterton Powermax? Renovating a house with limited space and this was recommended, also want a boiler with a powerful output for a soaking shower if anyone has any recommendations!
Thanks a lot.

No idea to be honest, chap called Gary posting here he's got a good grasp of all kinds of boilers, he might steer you in direction your looking for.

Pretty much all boilers are capable of heating water, as much hot water as you want. You should size your boiler only to suit total heat requirement in KW so best not go mad by over sizing, no real advantage to oversize, over sizing will only cost you more in usage.

Its possible to oversize when boiler is a self modulating boiler but I find those are only installed when possible house extension later on.

Find best boiler to meet your requirement within your budget.

Have a look at: http://www.powermax-repairs.co.uk/index.html.

I would advise you to work out your maximum hot water usage and design a system that can give you that, ie.. if you want two baths in the morning 80 liters each and a shower say 40 lites then thats 200 liters required via stored water or from a combi.

Using the old powermax stored system(the new version is not a stored water boiler), then the largest is 150 liters and once that has gone then the reheat time is 15/20 minutes, which may or may not be a problem to you, some storage systems say like the Viessmann have a plate heat exchanger inside so that when the stored water runs out then it will perform in the same way as a combi boiler. If you go for a combi boiler then go for one that has a high KW rating as the higher then the better the hot water performance.

If you decide on a mains fed appliance then you would need decent incoming mains to get the best out of these systems, if you don't have decent mains coming in to the house than any combi or mains fed appliance(powermax) may not give you the performance you require, if you wanted to boost the mains pressure then you would need to have a break tank holding enough water to at least match your maximum usage in one go, which then could be boosted with a decent pump giving great pressure to the property, there's a couple of other things that can help with pressure but i think the pumped break tank works the best. If you're mains is rubbish then you would just need to size you're cylinder(s) to match your requirement then you can easily pump that for a decent shower, Gary.
