Tell me more please! Which manufacturer has an extra long hose?

Its a twin barrelled pump but I lengthened the hose. Heyner brand.
 
Typical. Just ran to Halfords and all there’s the hoses were short. Also the dials don’t seem the best
 
Mains voltage compressor for me.
Saves me sweating.
The expansion vessels on unvented units are just too much for me doing it with a manual pump

As usual, odd advice from me. For pressurised heating systems ( to 1 bar ish), an electric Adidas / Puma sports pump from Sports Direct. Will get to 1 bar with ease, 2 bar with a struggle!!

For expansion vessels on unvented systems, a small CO2 cartridge in an emergency bike pump. They cost 49p/ cartridge and will charge to 4bar in 30 seconds - you then reduce the pressure to the required value.

With both, you don't need long hoses ( or foot pumps from the 1980’s) - sorry Townfanjon (but if you have it use it)

Quick, simple and effective.

The best advice I have recently received is to use a wet vac when changing radiator valves - simple, obvious and it works everytime. No potential for any mess.
