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?

gas leak, boiler not shutting down and always running flat out.

The Central Heating system has been checked out twice - but for some reason the radiators, especially the thermostats haven't been checked -

Sticking TRVs (Thermostatic Radiator Valves) are a common problem. The valve head is usually and easy DIY fix if you can identify the correct replacement, but the valve itself requires some plumbing work.

As a temporary workaround you can try closing the lockshield valve at the other end of the radiator.

Check those TRV’s , & get a wireless room thermostat fitted to the boiler.

Gas consumption for statics is rather like that of cars in that there are some crazy claims out there and some users are just heavier users than others.

The amount of gas consumed is certainly excessive however, If the boiler works continuously for any reason it will consume excessive gas. If the checks have been correctly carried out then the issue is the heating control settings.  The temperature of the water in the radiators is thermostatically controlled and adjustable at the boiler so there should never be dangerously hot radiators. If the room stats or radiator stats are set too high, or if there is a lot of heat loss in the building then the boiler will keep going full bore.

We have 4 radiators which have thermostats.  2 of the radiators work as you would expect - ie  turn them on full and the radiators get very hot - turn them down to 1 and they are on low heat.

 

However 2 of the radiators are red hot all the time no matter what setting the thermostat is set at.

 

Points to the thermostats - although for some reason despite the central heating system has been checked twice - the radiator thermostats have not been.

Check that gas bottle is not leaking by wetting the fittings with a soap solution and look for bubbles.

I had a small mesh filter dislodge from within my fitting that subsequently created a poor gas seal at the bottle and I only got 2/3 of what I expected from a gas bottle.
