installing central heating

[Dc]

I am about to have a go at installing oil fired central heating in our "old cold house" and was wondering if anyone knows any useful websites or has any info on how to proceed.

I need to know:

what size copper piping to use?
what's a good make of oil-fired boiler?
radiators in aluminium or steel?
what's the formula for size of boiler?
what's the formula for size of radiator in each room?
best place to buy all the gear?

any advice gratefully received!

regards
dc

Will the system have flow and return pipes with rads. dropping off as required or will all the rad feeds come back to manifolds. Use 16 or 14 mm pipe to rads.. Flow and return depends on overall size of the system.

Geminox is a good French make, but there are a lot of other good makes depending on your budget.

>radiators in aluminium or steel?

Depends on budget.

>what's the formula for size of

Rough guide is internal volume of the house in cu.m./15 = boiler size in kWatts.

>what's the formula for size of

Again very rough guide for main living rooms volume in cu.m. by 50 = rad size in Watts (by 40 for bedrooms).

Any number of French plumbers merchants but not Bricos.

All the above is very approx. and you should get some professional advice or you could end up wasting a lot of money.
