Just to throw another thought in .... our roof faces east-west (maybe slightly off this but close enough) - does that make solar even more debateable ?
Planning for solar water heating a future date

You and the rest of them clearly don't know about simple thermals storage. He goes on.....
I don't appear to be I am intelligent. Again he prattles.....
Read it all. Read it 6 times - I don't care if you move your lips.

Solar is worth it if you DIY...and as fuel prices rise becoming even more worthwhile.

And conversely NOT worthwhile if you have to have it professional fitted.
Even on a DIY basis, a typical two panel collector system is going to cost £2000 to buy for the panels, pipework and controls WITHOUT a cylinder or heat transfer device.
In that case, saving £100-£150 a year will still give a payback of about 20 years and that only arises as a result of increasing fuel prices. The savings only equate to the interest on the capital and thats on a DIY basis with no cost for installation.
Getting panels on to high roofs is likely to be beyond most DIYers unless scaffolding is used!

For an East-West roof the proper way would be to have panels on each roof and the controller will detect which set had the most solar gain and automatically switch to this set.
Even more reason not to have it due to installation cost.

Flat panels lose about 35% of the available pickup power on each set in your case!
However the tubes can be angled so they only lose about 15%
However tubes can be installed horizontally on a vertical south facing wall and are very efficient in that format.

But not in the winter.
Maybe I'll speak to my neighbour who does have a south facing roof (adjoining house and right next to where the hot water cylinder will be !)
They can be installed during the winter if the weather is warm and sunny like today!
Tubes would pick up quite a bit of heat on a day like today!

Tripe!!!!
Whole solar roofs are worth it. That is the tiles are stripped and the whole roof is a solar panel. Cheaper than a ground source heat pump. and cost only a pump to run.
Have it running UFH and it will be well worth it.
Have you ever installed any solar panels? Or even any gas boilers ?
Have you taken the Solar Assessments or even been on any manufacturer's solar courses??
Just how much do you think solar panels cost??? The average at the last show was over £800 !

yep. Even a whole solar roof.
stop being silly. I run rings around you.
Nope they are for the likes of you.

DD, please do let us see some photos of these installations of yours.
guys (and gals if there are any posting)
you crack me up ! Is this heating engineer 'sledging' ? to use a cricketing term ?
Just found out we might get gazumpted on the house anyway but reading these posts really cheers me up !
Just in case we do eventually get the house:
The thermal store sounds quite interesting - just to check, could we have one with immersion, solar coil, boiler coil and wood-burner stove input (wood burner won't be used much though and solar is for future installation maybe) ?
Any suggestions re. make/size for a 5 bed, 3 bath Victorian semi
Can these be sited in the loft (big tank of HW in loft - is that a good thing even if unpressurised ?)
Also, how far away from an external wall can a boiler be sited ?
