Was in B&Q tonight in Warrington and found a DeLonghi Pinguino PAC C110 Mobile Air Conditioner in the clearance section for only £50. It actually went through the till as £199, but then was reduced to £50 as on the sticker.
They had 3 left after I got mine. Cheapest I could see on-line in a quick search was over £200! Specs from the DeLonghi website are:
Air-to-Air Portable Air Conditioner
Cooling capacity: 11,000 Btu/h
Recommended for rooms up to 85m (squared)
Removes up to 24 l/d of excess moisture while conditioning
Only dehumidification function, removes up to 27 l/d of excess moisture
3 fan speeds
24hr digital timer and thermostat
Electronic controls with microprocessor
Autofan and AUTO function: the air conditioner automatically sets the fan speed and the operation mode according to the actual temperature in the room
Remote control with LCD
Refrigerant gas R410A
First post so hope it's a good one - I know its not exactly the weather to be buying an Air Con unit but at this price it seemed worth keeping for next year!
