What boiler type to install

Panic over, the boiler is fine 

The house was built 2007 and we've been in since 2012. It's an Ideal HE15 with tanks in the loft and landing.  
Hive system lets me mess with timings and I've got water to heat twice a day for 15mins a go.  This usually equals 7kwh and does our family of 4 for showers.
Using Boxt as a guide, a new regular boiler is approx £2.5k, whereas a combi is another grand.  Apart from better water pressure, and possibly savings on water when the kids move on in 10/15 years, why buy a combi?
Thanks

In your case, you'd probably (almost certainly) be silly to do so.
And a combi will only give better pressure if the mains can provide it - it might not. And, a combi will only supply one hot tap at a time; your setup will most likely handle more? 
And a combi will likely require a new gas pipe betwixt meter and boiler. And you'll lose your warm airing cupboard. And hot store which you could charge using solar panels.
The HE15 is getting on, but it's a pretty simple and robust machine. A friend had one - I guess as old as yours - that went faulty, and her local GS - who'd serviced it over the years - suggested it was no longer worth repairing. The replacement (can't recall what make, possibly the same) was, I think, £1700. Another heat-only boiler, but a condensing type, so more efficient. That was, ooh, 3-4 years ago?
£2.5 seems, perhaps, a touch high, but not bad. When the time comes, get quotes from a number of sources, and compare models, warranties, and prices.
It should be the easiest of swaps, esp if the current flue goes through the wall at the boiler? A condensate pipe will need running - just about the only complexity.
