We bought a new Caravan on a site 6 months ago - and it became clear virtually from the outset that the gas consumption was excessive. The site checked the gas installation but couldn't find any problems.
We have a Combi boiler feeding 4 radiators with Thermostats in the main bedroom. twin bedroom and 2 in the lounge area ( one near the entrance door and the other kitchen area) - there is a radiator in each of the 2 bathrooms.
We were at the caravan about 4 nights last November and then the boiler was put on a timer at low heat, until we decided to drain down the system for the winter.
But in that time - we used 3 x 47kg lpg bottles.
We then stayed at the caravan for a total of 8 nights during March and only had the heating on for about 3 hours each day - but used another gas Bottle.
There does seem to be a problem with the radiator in the kitchen area and main bedroom - in that the radiators are red hot even with the thermostat set to lowest setting. The other radiators work normally.
We were told told that our gas consumption would be about 4 bottles per year - and having stayed for a total of 2 weeks have used 4+ bottles already.
Any idea why (other than the problem with the radiators already mentioned) - we are using so much gas?
