Poor Shower presssure

11fernsroad

Our problem is that we have 4 bathrooms in our house and previous owner had installed a new combi boiler 38CDi.
But if we use a tap in kitchen the shower upstairs literally stops.It is even worse when two people use showers at the same time.
What would be the best and cheapest option to get some water flowing in at least two showers at the same time?
The water pressure at mains is very good.
Somebody adviced to go for Megaflow-but few others had said there are cheaper options and we could get water heated by combi to feed into hot water cylinder etc and get effective flow in the showers upstairs.
And how much would I be looking at to spend?We are based in Berkshire.

combi heater would be a good choice.

Megaflow type would be the best option, but there are other options available such as Alpha's flowsmart system.

Either way you're going to have to chuck money at the problem - the only 'cheap' way to sort out your problem is either electric showers or take it in turns.

Thanks a lot
We had a plumber come in today who said the present Worcester 38CDi (3 years) is not adequate to supply an unvented indirect cylinder,and hence needs new combi as well !!!
He said the present combi is just adequate enough to heat up the radiators in all rooms and it cant take any more strain.
We tend to take showers in the morning and use radiators in the evening(that too in winter only)
Any advice?

My plumber said combis are only really suitable for small homes - which your problem seems to agree with. So consider a different system rather than another combi would be my suggestion

Look at using a accumulator. If you have room for a cylinder fit this instead.

I have a pressurised unvented system and with two showers on upstairs there is hardly any loss in pressure if the hot tap is turned on in the kitchen. Just lots of lovely hot water.

Only drawback is that not all plumbers are qualified to work on such systems if they go wrong...
