Ordered a calor gas heater ... great product .....came on time .......completely useless , not worth a toss because you can't get a bottle of gas anywhere unless you already possess a suitable bottle , empty or full . Have been on to Calor Gas Appliances who Informed me they will not supply a bottle of gas either. This inability to get the main component of a gas heater should have been made loud and clear at the point of sale which is not the case. So unless you have access to a suitable bottle before you buy any calor gas products avoid the purchase or you will end up disgruntled and very very disappointed like this angry customer.
