central heating pump too large for boiler rating

[jacktara]

hello all
i have a central heating problem !!!!!!!!!!
have an ideal w100 boiler ,the problem is the pump required for the central heating is too large for the recommended rating ie 1amp max yet the pump required had to be 4amps.the manufacturer recommends fitting a relay for greater currents than 1amp. the question is where do i fit the relay ?
how do i wire it?
what type of relay?........manufacturer?.........rating?
any help greatly appreciated.

its in the electrics section

OP are you sure about this? most boilers are run on a 3 or 5 amp fuse (kestons use 10amp!) also what is the pump you are using?

If your system requires a massive pump, surely a tiny boiler, like your less than ideal Ideal is not up to the job?

Does one assume you are talking about the Imax W100 commercial boiler?

The fuse rating for this boiler is 5 amp, so you should have no problems with the pump if it is rated at 5 amp.

The 1 amp fuse you mention, I assume, can only be the pcb fuse? This should have nothing to do with the pump rating.
