Well I have just fitted a Flaming hot water the one of e bay and its very good and also easy to fit.I nave fitted it to the left hand back door of my van and I will not be cutting any hole into the van roof. I have to open the back doors to take out my poles from the pole tubes and then just leave them open for the heater.IT IS A LITTLE SLOW TO heat up but once it going it stays hot in the hose till the next house. Also warms up the van as the hose works like a big radiator.
I have invested 8 grand on van and new everything.Gutter vac, power waster ,van system hot system, and Slx and clx and its all working very well. All DIY and believe me its well equipped and ready to make cash.
I used my car with ladders for one year because I only had 200 quid to start. Then a back pack with Harris poles till I am were am today.
To all those starting it can get you down, its taken me 3 years of hard work.Today I own it all and paid cash and I am one of the oldest guys on the forum.
