alde bits / parts

Our ex-hire boat has an Alde boiler. It looks like Alvechurch chucked out the pump in the water tank and fitted a proper Johnson pump instead

People have reported Solar circulating pumps work well for boat central heating - about £25. but it means cutting into a pipe to fit one.

I like the sound of this, i always thought the pump in my alde was weak, takes a long time for hot water ot get to the last rad in the bedroom.

I have the system bled down at the minute as i have replaced all the rads and most of the pipework so an ideal time to try this.

What type of pump would you think would work best?

As I said above, ours is a Johnson pump like this: https://www.asap-supplies.com/johnson-fresh-water-circulating-pump-209602

We started looking for a cheaper alternative, in the end we picked up a Johnson (or one of the many rebrands of the pump) for a good price instead

Looks a bit cheap and cheerful, so I'd have a gate valve on each side so I could swap it without having to drain the whole system

That looks rather more substantial

I once mended one of these pumps with an 12v ''0'' gauge model railway loco electric motor for about £6 plus my time, nose suspended.  Can't remember the make or number of it, but Japanese though. You can have variable speed on the motor with a 12v model railway speed controller, and if its powerful enough run a train at the same time as pumping your water.

i ordered the pump of midland swindlers ..£95 ,,good price i thought
