this is by no means the cheapest way of installing and fitting a gas hot water system but heres my list for those of you that are thinking of adding hot water to your system for winter.
corwoods E-Z heater(L5) with no 20 min cut off £180
13kg LPG bottle(from local DIY shop) £35
car radiator hose(from any car spares shop)1m £5
rectus 26/QR gardiner fittings £40
LPG stickers,gas bottle strap £7
radashe koreel hi vis 100 reel(corwoods) £230
brass fittings for reel £13
so its cost me around £500 to be up and running with robust fittings,connections and a decent reel that can withstand the hot water.
i did foolishly buy the wrong heater on ebay so its cost me £63 for a natural gas heater which is in my dads garage!

.i also bought washing machine hose and boiler hose for hot outlet to reel which was also a waste of money.both are rubbish for hot water so that was about £16 wasted.
i already had 100m of thermobore and aqua daptor red pole hose(specifically made for hot) and oh i spent a tenner on a big thick piece of plywood to mount heater on and some heatproof insulation(£2).
ive still got to get a small fire extinguisher which ive not bought yet.
i also spent £120 on 4 new gardiner stiff brushes for the hot water although i think youll be fine if your just using it lukewarm to stop hoses freezing.
its been a bit frustrating over the last few weeks with connectors blowing off/fiddling with settings and then my accident but its a learning curve!

hopefully ill be back up and running again on monday morning!

best wishes to you all
