Kevin,
I have to say I have enjoyed reading your honest thoughts and views on your hot water system.It certainly has given me food for thought, its a shame others slag you off,when your only posting a topic that you feel can help other w/cleaners not only in the cold weather but in improving wfp effeciency.
Can I ask how much extra weight the hot water system weighs?
Does the hot water system use the Vans dieseal tank?
Does the hot water have a higher water flow rate then cold water in the winter?
How long does it take to have the system fitted and what warranty is offered with the product?
Where was it fitted?
Thanks Neil
