Which type of system??Help please.

Hello, I'm currently having to replace my combi-boiler due to its once a year feature of dying just before winter and need some advise on what to do now, please.

We have terrible flow rates off the cold main due to the original builders using galvanised iron pipes and them apparently rusting up on the inside. We get 5 litres per minute at best!! We know this because the water board came round to asses the problem and quote for a new main. Unfortunately the main runs down the opposite side of the street to us and replacing it will cost £1450 plus VAT!!! Ouch. Not something I can afford at present with the new boiler needed as well.

I would like to take a decent shower, not to powerful, just good, for the first time in 6 years. I will be installing solar in the near future so would like to go for a storage tank option and replace the tank when needed.

My question is which system will be best for producing decent flow rates (I'm not expecting mains pressure hot water) on both cold and hot taps and run the central heating. We have a decent distance from the loft to the shower head as the bathroom is between the ground and first floors. I'm told this should help with flow rates and to go with a system boiler with hot water and cold water tanks. Is this correct??

Any help is most appreciated.

You would be best off with a conventional system.

Conventional boiler
Twin Coil Indirect Cylinder
Possibly a need for pump on shower but you could try it out first.

Dont buy a cylinder and then change it later just buy a twin coil and leave the coil for the solar ready to connect at a later date.

Hi Although the water main is on the opposite side of the road, the communication pipe will run to the boundary of you property where a stopcock and or meter will be found. Your costs start there and down stream to your house. Try and get a flow test carried out at the stopcock on boundary. It is likely that the galv supply to the house changes to copper or lead from boundary stopcock. Good Luck

Thanks guys.

Plucky: When you say conventional boiler do you mean a system boiler or an open vented boiler??

JustLead1: We are on the end of a three house shared supply and the stopcock is approx 40m up the road. The guy from the water board tested the flow and said there was 145 l/min and loads of pressure at the stopcock. Hope this helps.
