Hi guys after having to put pants back on today after wearing shorts for weeks I'm starting to think we've had our 2 weeks of summer and as it's going to be my first winter with wfp I'm really concerned about freezing etc so I'm planning now and want to get a water heater fitted and set up way before the frost comes, can anyone recommend a decentish but cheapish mid range heater, seen some cheapo's on eBay but not sure how long they'll last and what sort of flow should I be looking at per min?
Are caravan heaters any use???
