Copper and brass replacement heater matrix for your Caterham 7
Once upon a time there was a generic heater matrix used on many different vehicles, this heater matrix this heater then found itself behind the dash of the ever popular Mini. This easy availability must have been the reason that the clever guys a Caterham decided to use it in the iconic Caterham 7.
History of the heaterThe original heater matrix was one of the first we encountered to be made in vast numbers using plastic tank technology. As the years went by Mini customers began to discover that it wasn't as strong as they would like. We were challenged by the enthusiasts to make a stronger version. We designed the heater in copper and brass removing the troublesome flange, adding strength but not compromising performance. This would last much longer at a competitive price and we have now been supplying that Mini heater for over 20 years. Whilst the original could have been better the imported heaters which flooded the market to replace it were considered to be utter rubbish. Customers flocked to buy them solely based on their price and were shocked to have to replace them within no time. There are still some of these dreadful heaters around so buyer beware!
Back to CaterhamOver the years we have had several customers say that they wanted our heater for a 'kit' car but could never really get any firm information as to which one. Not until recently that is. Fortunately a customer who is a Caterham 7 enthusiast bought one of our heaters and was more than happy to supply us with some information about which vehicles it was likely to fit and how it fitted.
Our customers vehicle was produced from the mid 90's to the mid 00's and is the type with the embossed 7 and the square heater box. You will be able to see from the pictures if your box or heater is the same, the new unit is top left and the old unit is top right. The heater matrix may fit other models and i'm sure we will get some feedback soon to help with better identification. He described how our heater was a couple of mm wider at the tanks than the original (it was designed for a Mini box after all) but with a few very minor alterations to the inside of his box it could easily be accommodated. We were told that these changes would not be a major problem if another owner insisted on an changing back to an original matrix in the future. Once the box is fitted back to the body you would never know the difference, as you can see from the pictures. In the words of our customer 'It isn't a straight swap as I said, but sometimes you have to be a bit creative! '
