If you want a quote on getting that Fujitsu installed I will see what I can do. As a floor console it will be more expensive that a high wall unit, the nocria would not be a bad choice either because if forces the air downwards.

You are right the heat pump is the cheapest way to heat that area unless you can find cheap firewood.

Yes, Please PM me a quote, though I don't know when or even if we'll be going the heat pump way as there's still some "Selling" to do at this end.

The Nocria unit looks good too and would consider something like that though I fear the draught from a wall mounted one may not meet with SWMBO's approval.

Is it just the unit price that's more expensive for the floor console or the installation as well?
