Seeking instructions/advice for an unused 30+ year old Myson "Heat Generator"

[n1ck3l50n]

I'm completely new to the forum so I apologize in advance if i'm in the wrong area.

Today I acquired what is best described as a "Hot Water Generator" by Myson. It has never been installed, the previous owner had it for 10 years but never installed it (It just sat in the garage). The issue we have is that it has no manual or installation instructions. We got it back and opened it up to find a check list dated 12/07/1982!

Connecting everything should be simple, I'm not a plumber but the guy that has acquired it has plumbing knowledge. The issue is the age and the fact that there are no controls on it so we really have nothing to go by.

If anyone has seen one of these and has any information it would be greatly appreciated!

Attached are some pictures:

How about contacting Myson as a start. I'm sure they would be interested.

in putting it in their museum and if that fails sell it to your local scrappie!

I agree with Simon on this one

Already tried that, they said that they no longer have anything to do with it and that certain products are supported by a third party company. They gave us a phone number. After ringing it they asked us to send some pictures so they could try to work out what it was! We've not heard anything yet.

hehe I agree it's probably a museum piece but we're just curious about it!

You're local scrappie will charge you for it as it's full of R502 and he'll have to get it decommissioned first

It is an early Heat Recovery / Air Source Heat Pump (ASHP) - did they have a swimming pool? These were sometimes used for them iirc.

As it mentions in the final assembly
Vacuum
Charge
Leak Test

These are standard procedures in ASHP's
The charge gas is R502 - that is commonly used in OLD ASHP's - it is no longer used - phased out in 1995 and MUST be disposed of in accordance with the regulations - not allowed to discharge to the air - can go to jail for that.

Being that age it would need a major overhaul and service before even attempting to fire it up, and would cost more to do that than to buy a modern equivalent. - What were you hoping to use it for - are you on mains gas?

Plumbers are not allowed to install or configure these - you'll need someone like ourselves certified as plumbers and refrigeration engineers (f-gas) to be compliant.

If you're not too far we would happily come and collect it and dispose of it properly for you.

Looked like an external oil boiler in background of one of the pics.

The guy we got it from bought it to use to heat a swimming pool but had it in storage for over 10 years! We got it for free so can't really complain. When we removed one side we found 2 gauges to indicate psi of something. One was right up but the other was on zero....

See, !'m not an oily, (we just decommission them) didn't notice that

the guy who's acquired it also has a pool that is heated but it's pretty big and takes a while. I think that's why he was interested in it. They have gas but it's not mains (from bottles)....I'm no expert so excuse inaccurate terminology

It is an external boiler

It will be more trouble than even it's scrap value is worth, he'd be far better off investing in one of these cheapies: Welcome to Dream Heat Pumps - 0845 459 9820 - FREE DELIVERY

However sizing for a swimming pool is critical (well sizing any heat pump is critical) else they are either over working or continually cycling both of which lead to an early death :death:

The gauges show refrigerant pressure.
Anyone with the appropriate knowledge would have no trouble installing it and setting it up without any instructions.

BUT it's a liability as you or whoever is in possession of it will find when they try and dispose of it.
Any money spent trying to install it will be wasted.

And finally as per Worcester's comment;
