Well you could just wrap the spigot with hessian tape impregnated with boss white and ram the whole lot into the gap. Not something I would recommend but it's something you could do yourself without having to get the owners 'tradesmen' involved.
Some of those old systems had no control over DHW and you could get a situation where, if no hot water had been drawn off for a while, there was a risk of scalding.
You find on some old oil systems that the primary circuit often includes a towel rail or radiator typically in a bathroom. Sometimes this circuit is extended to provide radiators in remote parts of the house and a second pump is added. If it was done by someone who knew what they were doing then...
If your FP720 has an industry standard backplate and your sparky wired it correctly then you could swap it for a Drayton LP722. I have a LP722 controlling pumped heating and gravity hot water. It replaced a mechanical controller that had an industry standard back plate meaning it was a matter...
