The clouds are moving

As i have said earlier( i think). Goggle is great but too much info becomes very confusing...thermal stores, khw, controllers, zones, How confusing! But Mark Brinkleys site has blown away the clouds, well, for today anyway. I am now thinking 'no ground source heat pump but solar slates, Eco Cat thermal store and wood burner...' we will see. I'll probably be back to an oil fired boiler tomorrow!
