Q: I am thinking of buying a Tornado and the literature states that it needs a 22mm cold feed. The feed to my house is 15mm, is this a problem?
 
  A: Yes - all connections on the Tornado / Tempest range are 22mm diameter, being the required diameter to achieve flow rates to gain the best performance from the cylinder.
 
Q: I have found a booklet which has a section where installation and service information should be logged. Who should complete this, and if it is not filled in is my guarantee affected?
 
  A: Yes - all unvented mains pressure cylinders require an annual service and should be installed by a suitably qualified person. Records supporting this information will be required should the guarantee be called into effect, and the booklet should be completed by the plumber/heating engineer carrying out the work.
