Minimising the heat loss between the HP and the house is absolutely vital, but I guess if you used massive amounts of insulation it could work. The only other reason I can think of is the power of the pump that moves the water between the thermal store and the HP. If you are having to pump that amount of water then it may need upgrading, or an additional pump adding inline. You'd have to take advice on that as I don't really know if it would be a problem. I wouldn't like to pay for the the cost of the copper pipe for the 30m run though!

I read an article about these some time ago and read that they are fitted in a large majority of houses on the continent. What are the major pluses and minuses (condensed)---- I take it that the two biggies are :
Plus -- Cheaper Heating (less emissions)
Minus -- Cost of fitting and installation (payback time).
Are these practical in inner city terrace houses? Cost to buy and fit for a 3 bed house??
