  3. does the job. 4 Star Review

    Posted by on 14th May 2014

    I wanted an economy 7 cylinder and bought this. What I got was an Economy 7 cylinder with extra direct flow/returns. These had to be blanked off. The rest was ideal, 22mm hot supply, 15mm threaded drain tap and two immersion heater bosses. The position of all the bosses was not ideal. looking down from the top, using the cylinder as an imaginary clock face, the immersion heaters are at six o'clock, the flow/return bosses are at three o'clock and the hot water and drain off bosses are at nine o'clock. When placed in my narrow cupboard so access to the immersions and their eventual replacement can take place and have access to the drain off, the two flow/return bosses are out of sight and are unable to be accessed without the removal of the tank, should they leak etc. In a wider cupboard this problem would not be apparent. having said that the tank is in and working well. The float valve needed bracing as the cold water tank wall is thin and allows the valve to bounce when filling. The foam lagging had been cut to access the bosses fitted but needed extra cutting as these cut outs were less than accurate, allowing for the immersion heater box spanner etc. I phoned rather than order off the net, staff were friendly and the tank arrived on the morning that was stated, well packaged in a box and lined in metres of bubble wrap.

    cylinder turned up well wrapped and on time (yes it really is a 24 hrs turn round). The foam lagging needed some trimming around the immersion heater bosses (as do most pre lagged cylinders, which is a pity when just a larger blind would make it neater). The tank lid is a nice tight fit. The tank is not supplied with a bylaw 30 kit so bear that in mind.
    A good product delivered on time. Will purchase from this company again
