Static caravan combi ....
Got my first static caravan with central heating earlier this year and never
thought about the frost protection function until this morning when there was a noise coming from the combi, it is freezing this morning here in south Airshire. It wasn't the noise of the extract you hear on over run is was a quieter noise. I am a bit worried because when we leave our van we always turn off the gas and the water and obviously any frost protection won't work. We just renewed the antifreeze in the radiator loop and was wondering was the noise the frost protection and should we leave the power and gas on when we are not here in cold weather ? .....and does the frost protection just protect the coils of the hot water system? ..... |

Turning off water to protect against frost won't help. You have to additionally drain down any part of the system not protected with antifreeze. ie hot and cold water. There's probably a drain off valve somewhere to do this. |

There's probably a drain off valve somewhere to do this. Additionally, when draining down, open all taps to get as much water out of the system as possible. If it's properly designed, there should be no/negligible water left in the system after draining down. |

Is the system one designed for caravans or a domestic one? Domestic ones (generally) have a 'frost stat' which will turn the system on if the temp goes too low to prevent damage, obviously you need to leave the gas and electric on for this. Another idea, just leave the heating on 'low', perhaps 10 degrees or even less, this will also help protect other water systems. I'm not familiar with water filled caravan heating systems - although I know they exist- our motorhome has ch but it isn't water filled. I drain the water tank etc and leave the taps 'on'. If it is very cold, I put the electric heater on low (we keep the mh on the drive), more as damp prevention, although we've never had an issue. You could consider a 'Hive' type system (assuming you have internet at the caravan). Then you could monitor the temp locally via your phone and turn the heating on when needed. That would be easy if the system is similar to or at least as easy to control as a domestic, perhaps 'single channel' (no hot water) domestic system. -- Smile for the camera ;-) https://www.youtube.com/watch?v=HxyL2_38EsQ https://www.gov.uk/report-benefit-fraud https://www.jobcentreguide.org/claim...-benefit-fraud https://childsworldamerica.org/anima...o-child-abuse/ |

So much for your boast that you have more money know what to do with. Sounds more like 'Penny wise, pound foolish.'
