Default Strange (to me) pipe sizes

Hi chaps,

i am lucky enough to be about to plumb in my new heat pump! But
unfortunately the pipes sizes coming out the back, I'm not familiar

with the
sizes! There are 6 pipe stubs, 2 at 38mm, 2 at 27mm and 2 plastic

ones at
25mm. How the hell am i gonna plumb these in? I suppose what i

need are
reducers/converters to either 28mm or 22mm so i can plumb to the

buffer and
hot water tanks.

Are these sizes known as anything else? Where can i find fittings?

Also, the installation manual asks that traps be fitted on the

inlets to the
pump, are there such filters easily available?

cheers

Steve


What is the country of origin?

AWEM


Pump is from china, i am in France, but will source all the fittings in
England as my French isn't quite up to scratch, and getting anything in
France is a nightmare, i would end up driving many many miles tracking bits
and pieces down! I have measured the internal diameter of the large pipe
and it appears to be 35mm ID, the smaller copper pipes are about 23mm ID, so
are these 35mm and 22mm pipes? Id like to be able to use compression
fittings on the back of the heat pump rather than solder. I imagine i will
have to solvent weld the plastic pipes?

Cheers

Steve
