Best storage heaters & ways to heat large area??

Lmnover

i have 20 x 40 steeltech shed that we have insulated and plan to put 2 offices and a small showroom into at the back of the house. I was thinking of heating 2 offices with storage heaters as they would be used regularly while the large area only needs occasional heat when someone comes in etc.
I have heard there are new energy efficient storage heaters but dont have any details on these?
also was considering some type of blow heater for the large area but not sure? any ideas appreciated as not the kind of thing we want to get wrong considering the winters we are having!:cool:

Nothing worse than a cold office, and blowing steam in front of you when thinking of buying something!

electric heating is rather crap in terms of cost compared to gas or oil, and the method to reduce that cost using storage heaters isn't very controllable instantaneously.

Is there any possibility you can run an LPHW feed from the house (presuming you have a boiler there?) or install a small modulating gas/oil boiler in the shed?

Presuming not, you could look at this: http://www.dimplex.co.uk/products/domestic_heating/installed_heating/duoheat_radiator/duoheat_radiator/index.htm

and for the showroom, a reverse cycle AC unit such as this: http://www.mitsubishi-aircon.co.uk/mitsubishi_electric.asp?id=198656&smn=000000000000227034

Whether you go with electric or LPHW, proper controls are essential - using thermostats & timers for the office, and thermostat, timer and even a presence sensor for the showroom.

What sort if insulation did you use, and it's on the walls & roof?
