I am planning on installing a central heating myself. I'm probably going to buy a full system from Mr Central heating (.com). I'm going to stick to the usual 22/15mm copper system as I have some experience of working with copper. I was wondering whether anyone could reccomend a potterton 28 or Vokera compact 28? They are both about 100,000 BTU. Do you reakon that either of these will be enough to power a shower tower from home base (The silver one at £250) Any comments on any of the above would be appreciated.

It is worth checking the flow rate needed for the shower with the manufacturer and compare this to the boiler spec. Then add in a bit of slack as the flow rate at a given temperature will drop in winter when the water is colder coming into the boiler. If the shower is the one with side jets I would imagine you would need a pretty high flow rate or you would lose pressure if they were all working together and someone turned on the hot tap downstairs. I plumbed my own system in plastic (Hep20) as I was being quoted some large numbers by various plumbers. Good Luck!
Thanks Ant. The flow rate for both boilers are the same 13.5l/min. Do you (or anyone else) know whether this will work well with the shower tower? It does have the jets you mentioned. Any other views on these two boilers would be appreciated.
If the flow rates are about the same then it sounds like it should work but it may be worth getting a larger boiler as if hot water is used elsewhere in the house at the same time as the shower the pressure will drop. Also, the figures quoted will probably be under optimum conditions. As I said the flow rate at a given temp will be less in the winter when the water is colder to start with. I hope this helps.

Breezer - I appreciate your concern. But as I work for Transco I'm aware of the safety implications of connecting the gas supply. I'd loose my job if I fitted it myself and someone found out. I will definitely be getting a CORGI registered fitter in. No advice on whether Vokera or Potterton is best?
