Bloody tired of being confused. What heating system to fit ?

By smaller cylinder, you mean a smaller UVC than you might otherwise install?

 

Heat pump cylinders are generally big because they store water at 45 to 50. A typical direct cylinder could just as easily be at 70 degs, so effectively a much smaller cylinder holds just as much energy.

@Adrian Walker Also, i believe that at below 3 i would be required to fit MVHR. It is a shame but just really not got the space. I will have to have have 6 extractors for all the wet areas. I will have to have a look and consider what my options are on that front.

If you want a healthy & happy home you should have MVHR. It doesn’t take a lot of room, you can self install and will save on your heating bills.

No space in a 1,750 square foot house? I'm not the only one that's fitted one in an apartment a fraction of that size; they really aren't that big. Could go on the wall or ceiling of the laundry room, or study next the hot water tank, or the kitchen, or the largish entrance hall, or the WC...

At what stage are you planning to market the build? I'm wondering if there's any scenario where you might sell off plan and let the buyer choose the heating and internals? You'd also get some validation of the likely sale value. Or any other scenario that would let you build both side by side as there must be economies to be made. 

Ideally you'd keep both builds as similar as possible but only your own will qualify for a grant which does complicate things. What do estate agents say about ashp versus gas boiler?
