I always take out insurance when the manufacturing warranty has ended and pay for a proper annual service until I take out insurance which includes one.

Hi again. I've timed the revolutions on the gas meter. There are three red ones. The first takes 21 seconds to do a full turn, the second one in takes 3 minutes 35. I turned the hot water on and strangely instead of speeding up it slowed to 24 seconds. Do these figures sound normal speed? The thermostat is on 10. Thanks
weird I turned the hot water off so it was just heating and it went faster taking 25 seconds, turned on water again and it slowed to 35 seconds.

Wouldn't dare dream of not gas rating an appliance on service, Thought it was mandatory !!!!!!!!

Are you at the wind up villa?
You never gas rate a back boiler, but you check the burner pressure?
The scenario I give trainees is " you get called to a boiler which is now not heating the rads as quickly or they aren't getting as hot, you check the MI and it says BP 13 mb, you fit u gauge and confirm BP is 13 mb what could be the prob, and how do you check it"?
The answer could be lack of gas, getting to the burner, therefore not burning, the easiest check in the world and one of the most ignored is gas rate, before I check BP I would gas rate all day every day, if the boiler is 28kw a quick gas rate tells you if it is getting full gas, checking BP tells you there is gas at the test point NOT that it is getting burned, due usually to the burner needing cleaned.
Imagine checking BP then blocking an injector with your thumb, the flame would drop and put the burner out but what would it do to the BP? ( nothing, therefore BP only is hardly worth the bother)

RG3 just refers to the fire!
The data plate for the boiler can be seen if you lie down and look under the fire. You will need a torch! It will probably be the Bermuda Inset 51/5 (GC No: 44 075 06).
That boiler has an output which can be adjusted (by a Gas Safe Engineer) between 7.5 and 15kW. The input is between 9.3 and 18.6kW
So you are heating up the house twice a day from cold. No wonder you have high gas consumption!
33kWh over 2 hours is 16.5kW per hour. The boiler consumes 18kW per hour (see my previous post), so it is running flat out for about 55 minutes per hour.
Putting the idea of a combi boiler to one side for a moment, you need to check how much heating your house needs. The easiest way to do this is to use the Whole House Boiler Size Calculator. I doubt very much if you need 18kW in a two bed house with eight rads.
The next thing to do is to check if your rads can provide the required heat. Use the first table in Stelrad Elite Catalogue to find out.
