In the past, I've come across* a few commercial heating installations where the pumps are connected with plugs (often a 16A BS4343, aka "commando"). Makes sense as it avoids having the heating fitter have to do anything with the fixed wiring if they have to change a pump out.
At church, I had to diagnose a problem with the heating - blowing fuses and tripping the upstream MCB. The last person to do any wiring used cooker connection units for pump and boiler - so I had to disconnect wiring to isolate them. Turned out to be a faulty frost stat which passed IR tests @ 500V but "popped" when power applied to the system
Some changes to the system are needed, and I was thinking about plugs & sockets ...
The boiler is very basic at the moment - no permanent live, just apply power and it fires up. But since most boilers need both a permanent and switched live, that would mean a 4 pole plug & socket. Other than the Klix designed for emergency lighting, I can't think of anything that wouldn't be "misuse" - eg using a red BS4343 socket might lead to confusion.
It does need to be something that the "average" heating system engineer or plumber will understand
* Often the data cabinets are stuck in a services room/cellar along with the boilers etc. In one case, I was installing a network connection for a new building management system to connect to.
