Goldair 1200W radiant heater

This is an excellent heater. It’s practical, lightweight, easy to use and gives instant warmth as well as being affordable. The level of heat can be adjusted to one, two or all three bars. I highly recommended it. Fan from Double Bay Hardware was incredibly helpful and accomodating. Wonderful customer service. Cheers, Evelin.

Have only used 1, the other is spare as it is difficult to find these globes & the other one will probably blow any day now as they are connected to the same switch. Works as expected.

I ordered two small light bulbs on line as nobody seemed to stock the ones I needed..
They arrived in a day!
It is so gratifying to find a hardware store that genuinely cares about its customers.
I am also glad to see so many positive reviews.
I live in Crows Nest but I will now make a trip to Double Bay just to check these guys out.
I noticed a review by a customer saying that the prices are too high and to go to Rose Bay Bunnings.
O.K. go to Bunnings and try and get some really knowledgeable advice.
Chances are YOU WON'T!
I would rather deal with genuine people in this world who KNOW what they are talking about and that goes for ALL businesses..
