If you go down the Heat pump rout I do not see the need for additional systems. Ours does all the hot water we need using 2.3 kWh per day for this and has never gone wrong in 6 years. To back up what knighty said you would be hard pushed to find anyone who would tell you their house had to much insulation so do all you can within the space you have available. I put in more than the regulations at the time required but I still wish I had done more as even with an efficient heating system it is still is not free to run and will only get worse as the costs of energy go up.

I have fitted a whole house heat pump.  I am very impressed with price quoted 1500  for a Sanyo rotary compressor of 15Kw output . it has performed exstremely well, I have it installed as a Hybrid with my old system of 10 rads and under floor all on separate zone M/Valves. Even during the coldest days I am well impressed during my trials and temperature dependent Hybrid use.

The Dimplex heat pump uses a Copeland Scroll compressor. Any experience with them, reliable, efficient? I think you're right, if the heat pump will do everything we need, there's not a huge point in paying any more capital expenditure for another system. May aswell upgrade any insulation as everyone says.

Dimplex are good but Kensa are also good, and simpler too, they are local to you and if you work with a local installer you should be ok.  I have worked on projects with both and Kensa units seem rugged and do deliver.  I have seen COP of 4 on well designed Kensa system, using a heat meter and a kWh meter, so they can do the business.  Spend time to reduce you heat demand as much as you can, Kensa make a 3kW heat pump now, called the shoe box, if you could use that you would be on to a winner.  Just a side note, have you got the OK from Western Power to install a heat pump, I think the form you need to submit is called a J form.

Cheers
