£3,700 spent on our new (HEAT ONLY) boiler and a tad dissapointed because no hot water after 2 baths

Setting the water temperature too high, especially in a hard water area, will see a massive build up of scale inside the tank. Whilst I see your point that the hotter water won't be used as quickly, 60°C is plenty hot enough. If there is a concern about Legionella, maintaining a temperature of over 55°C for a couple of hours will kill off the bacteria.

Fitting a larger tank is an option, but the OP will need to check that the joists under it can take the extra weight.

And if you set it above 60C/65C and you have a shower pump it can cause them to fail and will definitely void most manufacturers warranties  

If they have a shower pumps that will be using more water than needed.

I would tell them all:  baths are to be taken the evening before and only showers in a morning.
Who has the time to have a bath in the morning?

At the moment, quite a large percentage of the population.

I've just re-read the OP's opening post following some replies above. His family are having baths in the morning?

Good lawd. No wonder there's a hot water shortage...

Reading between the lines I would assume you have a megaflow unvented cylinder which will take anywhere from 30 - 60 mins to reheat, baths will use the most water while showers obviously use less, you are used to continuous hot water from a combi you will have to get used to a limited supply of stored water

OP, I have a bath every morning and it's great. Did so before covid, and will continue to do so. Doesn't cause any problems in our house as the other 2 have showers - we have an electric over the bath shower, so obviously they wait until i get out. Anyhow, I'd have thought that's the easiest solution for you as you can have an electric shower any time you want. Shouldn't cost much to install, just needs a cold water feed and electrickery supply.

Fitting a smaller bath might be another approach.

...or encourage the morning ritual of a cold bath!

More seriously, though, it is a sad fact of life that these family pressures on living space are short-lived and all too often, by the time you invest in the solution, the "problem" has grown up and left the nest!  (...or is still in the nest but has turned nocturnal, so no longer competing in the morning!)

Even when I was at my desk in town for 07:00 I still used to prefer a bath to a shower. It only really adds about 5 minutes to the morning routine.
